《长城与边界——明朝北疆边界意识及其前近代特征》

作　　者：赵现海

文　　摘：
与现代民族国家具有明确边界意识不同，中国古代边疆是一种动态变化的疆域而非固定不变的疆界。在洪武、永乐时期国力强盛之时，长城只是“内边疆”军事体系，与边界并无关系。但仁宣以后，伴随国力下降与防线内缩，边墙遂成为明朝、蒙古政权边界。在此之外，明朝尚设置界碑、边墩，将之定位为“军事边疆”，以作为边界防御之缓冲。但在明后期，伴随蒙古对明朝威胁加剧，明朝已在事实上丧失了对边墙以外的控制功能，这一局面在“隆庆和议”后进一步合法化。概而言之，对于长城与边界之关系，应从中国古代独特之边疆意识入手，考察其“前近代”特征与变化轨迹，而不应与当代边疆概念简单比附。
关 键 词：长城 政权边界 军事边疆 明代
正　　文：
关于中国古代长城与边界之关系，国内外学者具有不同的观点。西方学者对长城的研究，往往在“内亚”（Inner Asia）视野之下，将长城视为分隔中国内地与边疆的象征。中国学者则更为倾向于长城只是一种军事体系，而非固定边界。如唐晓峰对苏联学者瓦西 ……

Hi everyone, I wished to bring up the topic of the Color analysis test,
which I have been interested in for a considerable time.
This captivating method is often used to identify which colors best suit an individual's natural skin tone, hair, and eye color.
Since it merges elements of art and science, I
decided to raise this question here and explore how it influences personal style and confidence.



One of the most intriguing aspects of the Color analysis test is its emphasis
on categorizing people into different seasonal palettes,
such as Spring, Summer, Autumn, and Winter. Many people overlook the power
of wearing colors that harmonize with their natural features, but
this test shows how the right shades can dramatically enhance your appearance.
From my observation, understanding your color palette can help prevent costly fashion mistakes
and boost self-esteem by highlighting your best traits.
The concept of [b]color harmony[/b] plays a vital role here, directing users to make educated
and dynamic choices.

To conclude, the Color analysis test provides a unique and practical approach to understanding personal aesthetics through color.
It's a topic that touches both creativity and self-expression, and I believe many of you might have
valuable insights or experiences to share. What do you think?
I would like to hear your opinion and stories about how color analysis has impacted your style or perception.

It’s unlikely that creatine dietary supplements will technically
break your quick or kick you out of the fasted state due to minimal results on insulin and autophagy.
So will taking creatine supplements throughout your quick negatively influence insulin ranges or autophagy?
When fasting for weight loss, you need to ensure that no
matter you devour throughout your fasting window has
little to no calories and doesn’t create an insulin spike.
Anything you devour mustn't stimulate your GI tract when fasting for intestine
rest. Pure creatine monohydrate, with nothing extra in it, won’t mess
together with your quick.
Strategically incorporating these supplements can help handle nutrient gaps during caloric
restriction, supporting power metabolism, immune operate,
and general well-being. It reduces oxidative stress, improves lipid profile, and reduces insulin resistance in overweight patients—furthermore, zinc supplementation aids in bone density and tissue
production. However, too much potassium also has side effects, so staying within the really helpful every day intake of 2,600
for females and three,400 for males is essential.
It is beneficial to consult with a healthcare skilled or a registered dietitian who can provide personalized
guidance based mostly in your specific wants and targets.
You will want to enhance your protein and water consumption if
you’re seeking to bulk up. Fasting with creatine helps you shed excess calories and lose fatty weight.
For example, taking creatine throughout a fast helps your muscular
tissues break down extra ATP to produce power. Also, your body
is automatically set to use up extra sugars
and fat to release power on your actions. In truth, ingesting it will assist your burning of
energy all through the day. Equally, other research means that creatine supplementation can enhance glucose tolerance but does not affect insulin sensitivity in healthy males undergoing aerobic training 9.

Figuring Out how creatine and fasting work helps you make good selections on your health and health aspirations.
Use each methods to your benefit, ensuring your plan matches your private necessities.
Creatine is key for making vitality, particularly for fast, powerful actions.

When we train exhausting, ATP runs out fast, and that’s once we feel tired.

Creatine gives ATP a boost, letting muscle tissue maintain making vitality for read more On neurotrauma`s Official blog time.
Ketosis is primarily influenced by carbohydrate restriction, while creatine just
isn't a big supply of carbohydrates. Therefore, creatine supplementation is unlikely to disrupt ketosis.


One of the key aspects of water fasting is to abstain from consuming any
energy or nutrients for a certain time period, usually starting from 24 hours to several days.
Throughout this time, the body enters a state of ketosis, where it burns
saved fats for energy as an alternative of glucose from
meals. By introducing creatine into the mix, it may disrupt this process and probably have an effect on the general benefits of fasting.
Additionally, creatine is often consumed with water, which technically breaks the fast as it introduces calories into the physique.

Before diving into timing, it’s necessary to know how creatine
works. This naturally occurring compound is saved in our
muscles and plays a significant function in energy manufacturing throughout
high-intensity exercises. By supplementing with creatine,
you'll find a way to enhance your athletic efficiency, strength, and
muscle features.
Nonetheless, technically talking, amino acids will induce
an insulin response that will cease the autophagy course of and break
your quick. There is a direct association between intermittent
fasting and weight reduction. Creatine could be a helpful complement if you're a well-trained athlete,
particularly should you aren't presently consuming animal merchandise wealthy in creatine.

However, if you're an off-the-cuff athlete or not utilizing truly high intensity training,
then creatine supplements might not provide a lot profit and will even lead to some
weight achieve.
There’s been a long-standing debate in the health world about
whether you must take creatine and caffeine collectively, but most fashionable research exhibits
there’s no need to worry. While an older research as soon as instructed that caffeine may blunt creatine’s efficiency advantages, this has not been consistently supported by newer analysis.
In truth, many athletes and gym-goers take each successfully and see improvements in both energy and
endurance. Creatine pulls water into muscle cells, and
caffeine has a light diuretic impact.
Throughout intermittent fasting, the principle purpose is to consume no calories so
that your blood sugar ranges are not raised in any
respect. So, how will you have the power to consume pre-workout for intermittent fasting?
In fact, evidence suggests that creatine supplementation can lead to larger fat loss
over time when mixed with a nutritious diet and regular resistance
coaching.
Just make certain it’s unflavored, additive-free, and not taken throughout prolonged fasts
if autophagy is your primary goal. The method your physique
absorbs creatine into muscle cells is another consideration. Combining creatine with carbohydrates will assist increase
insulin release, so improving the absorption into your muscle tissue.
Although this isn’t required, if you wish to maximize each
aspect of your supplements, this is a good strategy. Although you may lose this little
advantage should you take creatine on an empty stomach, over time
your muscles will nonetheless saturate with creatine
as long as you would possibly be regular. Even with out train, creatine supplementation can keep
sufficient creatine phosphate ranges, supporting energy metabolism and lowering fatigue throughout daily activities.

Any impression on your glucose ranges technically breaks your quick, even when you’re not consuming
calories. In this case, taking creatine supplements does break the fast,
and whereas this take a look at was carried out on rats, many times it’s carried out as a precursor to human testing with
comparable results. The brief reply is sure, however there are necessary components to think about.

Creatine is a popular complement amongst athletes and fitness fanatics
for its potential to reinforce performance, enhance muscle mass, and
speed up recovery.

The legal consequences of non-prescriptive Sustanon 250 use in plenty of
countries can also result in fines and prolonged jail time.
As with different testosterone merchandise, Sustanon 250 can produce several undesirable unwanted facet effects.
The liver pressure will be vital (albeit most likely
tolerable) as a result of Anadrol being the only hepatotoxic compound current.
Nonetheless, we have discovered that running higher dosages will trigger more
pronounced unwanted aspect effects, which we are going
to detail in the unwanted side effects part
of this guide (further down).
Winstrol could be taken orally at 20 – 60mg per day, relying on your wants.
That stated, you would goal for a hundred – 200mg per week, however
even as little as 75mg would do you superb. Nonetheless, these numbers will convey a
host of unwanted aspect effects so be prepared for that.
Please remember that androgenic issues are not reversible in females, therefore why it's by no means a good
suggestion to threat combining this product with another substances whilst on cycle as a feminine
consumer. Newbies are encouraged to maintain cycles easy, under
management, and brief in period. D-Bal is the legal various of Dianabol, which is in style for hardcore
bulking results. Anavar is non-aromatizing and has a
relatively mild impact on liver enzymes, particularly at average doses.

In our experience, the inclusion of Deca Durabolin can improve the severity of
unwanted side effects, albeit in a more manageable way than different anabolic steroids.
Dianabol works by growing protein synthesis and nitrogen retention, which finally ends up in muscle growth.
However, Dianabol can even cause unwanted effects such as water retention, acne,
and liver damage. Trenbolone, like Winstrol, has muscle-building and fat-burning attributes, with it also making
a dry and grainy look to the muscles. It is a complementary
stack as a outcome of testosterone isn't an overly harsh steroid,
so it won't dramatically worsen Winstrol’s
already toxic nature. Nonetheless, gynecomastia is now a concern due to the presence of testosterone, potentially causing hyperestrogenism (5).

Users can scale back estrogen unwanted effects,
corresponding to water retention and gynecomastia, by taking an anti-aromatase inhibitor or a SERM (selective estrogen receptor
modulator).
While these aren’t life-threatening side effects, they are often some of the most distressing for
men because they are so visually noticeable. Since Testosterone Cypionate is often used
for 16 to twenty weeks or more, you could want a longer-than-normal PCT cycle – but four weeks
must be your absolute minimum. The typical dosing technique for any SERM utilized in PCT is to start at a better dose (40mg
of Nolvadex, for example) and scale back the dosage by half for the ultimate week solely.
Adding Deca to the stack will ensure you develop that big, full,
pumped look, and with basic common sense, you must have the power
to management water retention well on this stack. If your dosage of Testosterone
Cypionate is taken too high on this stack, water retention may turn into extra of a problem – which is why I advocate 600mg max.

Nevertheless, it’s still important to know that androgenic effects are
attainable in some users. Androgenic results are a extra critical concern for female users of Equipoise,
and virilization is an actual chance, especially where larger doses are taken.
Anadrol is an oral bulking steroid typically stacked with EQ for a short portion of the cycle.
EQ is not a giant power booster, so Anadrol takes the lead and pumps up strength gains, whereas EQ enhances endurance – making for a
killer performance combo. Most novices will only take a glance at including
testosterone in a stack with EQ to fight the suppressive nature of Boldenone.


Few males will ever be dissatisfied with a Testosterone Enanthate-only cycle, which may be both a bulking or cutting cycle.

It’s additionally the most secure steroid cycle you can do, offering exceptional power and muscle features if you
use it with a high quality diet and training program.
Testosterone Enanthate is possibly probably the most broadly used steroid as it is widely obtainable,
inexpensive, and very effective for efficiency enhancement.

These and different PCT drugs35 include their potential side effects, so at all times do your research before deciding which
ones to use. Each guy will have a different bulking objective, ranging from
wanting relatively mild features to most mass positive aspects using the most potent compounds.
Most will nonetheless need to take a bare
minimal of a thousand additional energy day by day.
This has vital benefits but additionally provides you some sense of invincibility, but again, most
users are still finest advised head To the valley's site stick with standard rep ranges for injury avoidance.
Some steroids, like Deca, are distinctive at helping heal damage and constructing
cartilage, but no compound will make you indestructible or resistant to new injuries.

Your pores and skin seems pinkish because there's an elevated flow of oxygenated
blood within the vessels close to the floor of your skin. Dbol use also results in an increased affinity
for binding to androgen receptors. In case you are
at the intermediate stage, you can opt for a 50 mg cycle every day.
Then there are extra superior users who can take as much as 100 mg
of Winstrol day by day.
Our licensed staff helps information you thru the critical recovery
phase post-cycle. Whether it’s hormone restoration, coaching changes, or vitamin optimization—we’ll help you keep your gains and feel your greatest.
An elite nighttime formula engineered to naturally enhance testosterone levels, reduce cortisol,
and improve deep sleep for maximum hormonal recovery.
Boosts natural testosterone production, supports adrenal
operate, and balances hormone output after cycle suppression.
Winstrol is handiest for intermediate to superior athletes who've
already established a robust basis of coaching, nutrition, and hormone schooling.
These individuals are better prepared to handle the
precise dosing, timing, and cycle support required to make use of Winstrol successfully.


Maintain a food regimen low in saturated fats and engage
in cardiovascular train to support coronary heart health.
Regular monitoring by a medical professional is really helpful to manage these risks.

Nevertheless, most users report seeing important positive aspects in muscle mass and power inside the
first few weeks of starting their cycle.

Методы обработки лент из драгоценных
металлов для долговечности
Методы обработки лент из драгоценных металлов для
повышения их долговечности и прочности
Для достижения высокой долговечности
изделий необходимо придерживаться нескольких ключевых рекомендаций.
Применение метода горячей прокатки позволяет улучшить структуру материала и обеспечить его высокую
прочность. Эффективная температура прокатки должна составлять около 1200 градусов по Цельсию, что обеспечивает нужную
пластичность без потери качества.

С особым вниманием стоит отнестись к процессу закалки.
Использование медленно остывающих жидкостей, таких
как масло или специальный раствор, помогает
достичь оптимального баланса между жесткостью и
малой хрупкостью. Важно контролировать температуру остывания, которая не должна превышать 400 градусов, чтобы
избежать неожиданных физических изменений.

Для предотвращения коррозии рекомендуется покрывать изделия защитными слоями.
Нанесение никелевого или специального защитного покрытия не только
улучшает внешний вид, но и значительно увеличивает срок
службы. К тому же, регулярная полировка помогает устранить мелкие царапины и сохраняет блеск на долгие годы.

При хранении важно учитывать воздействие на металл
внешней среды. Храните изделия в сухом месте, вдали от влаги и
прямых солнечных лучей. Использование специальных контейнеров
с антикоррозийными добавками значительно упрощает задачу защиты ваших украшений.

Повышение коррозионной стойкости лент из золота и серебра
Для улучшения коррозионной
стойкости изделий из золота и серебра применять легкие
покрытия из родия или палладия.

Эти металлы образуют очень тонкие, но прочные слои,
которые значительно снижают воздействие внешней агрессии на основные материалы.

Дополнительно стоит использовать комбинацию технологий анодирования и пассивирования.
Пассивирующие растворы, содержащие,
например, хромовую кислоту, формируют на поверхности защитный
оксидный слой, который предотвращает коррозию.

Регулярное очищение с использованием мягких неабразивных средств предотвратит накопление грязи
и окислов, которые могут привести к разрушению.
Рекомендуется использовать растворы на основе мыльной воды, избегая кислот и щелочей.

Избегайте постоянного контакта с химическими веществами.
Например, парфюмерия, косметика, и средства бытовой химии могут ускорить процесс старения и
вызывать пятна. Поэтому рекомендуется снимать украшения перед использованием этих продуктов.

Хранение изделий в специализированных антикоррозийных упаковках или контейнерах сделает их
долговечными. Это ограничит доступ воздуха и влаги, что является основным
фактором коррозии.
Кроме того, стоит рассмотреть возможность использования сплавов с добавлением
меди или цинка. Эти компоненты могут улучшить прочностные
характеристики и коррозионные свойства
при корректной обработке.
Технологии механической обработки для улучшения
прочности лент из платиновых сплавов
Использование термообработки в сочетании
с различными методами механического воздействия значительно
повышает прочность платиновых сплавов.
Например, закалка и последующее отжигание позволяют изменить микроструктуру материала, делая его более
устойчивым к трещинам и деформациям.


Абрезивное шлифование с регулируемой глубиной резания помогает создать гладкую поверхность, снижая внутренние
напряжения. При этом важно учитывать выбор шлифовальных инструментов: алмазные абразивы показывают
высокую эффективность
при работе с платиновыми сплавами.
Параметры скорости вращения и подачи также
требуют внимательного регулирования для достижения оптимального результата.


Контроль температуры в процессе механического воздействия
не менее значим. Существуют технологии, позволяющие поддерживать необходимый
температурный режим, что содействует минимизации
термоупругих изменений.

Внедрение таких системоградирует к
повышению однородности механических свойств.


Вакуумное напыление дополнительного
слоя, состоящего из более прочного материала, является отличной практикой для защиты от
износа. Этот метод обеспечивает высокую адгезию и увеличивает срок
службы изделий.
Разработка и внедрение числового программного управления (ЧПУ)
способствуют точности
обработки, минимизируя вероятность неравномерного наматывания и создания микровпадин,
которые могут служить точками концентрации напряжений.

Финишная обработка с помощью лазерной техники
позволяет точно настраивать толщину и геометрию, увеличивая таким образом механическую прочность.
Исследования показывают, что применение фемтосекундных лазеров помогает уменьшить термическое воздействие
на материал, сохраняя его исходные характеристики.

Переход на многоступенчатое формование
является еще одним шагом к
повышению прочности. Это позволяет перераспределить напряжения и
снизить риск возникновения трещин в результате неравномерного распределения силы.

Оценка и анализ полученных изделий
с использованием неразрушающего контроля важны для
обеспечения необходимого уровня качества.
Это наблюдение позволяет своевременно выявлять дефекты, что существенно снижает риск
осложнений в ходе эксплуатации.

Do you have a spam issue on this blog; I also am a blogger,
and I was wanting to know your situation; we have developed some
nice practices and we are looking to trade
techniques with other folks, please shoot me an email if interested.
