“现代汉语缺乏严格意义上的形态变化”这一总的特征，使汉语的时体系统某些方面也呈现出自己的特点。

The character of "lacking in restricted morphological change in modern Chinese" makes some parts of Chinese tense and aspect system present its own features.

计算结果表明，热脉冲作用下，转变时体系平均温度高于平衡计算熔点，结构转变是过热熔化过程，系统不可能发生从晶态到非晶态非平衡转变。

The results show that the average system temperature is higher than the calculated equilibrium melting point of cu while the transformation occurs which should be an overheated melting process.

众所周知，当提到接触 STEM（科学、技术、工程学、数学）课程时，公共教育体系存在巨大的空白。

We all know there exists a great void in the public educational system when it comes to exposure to STEM (Science, Technology, Engineering and Mathematics) courses.

So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.

因此，当我们考虑一个键的长度的时候，这就应该是我们的键长，这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。

And so what I get is the energy of the system at the equilibrium separation is given by minus z plus.

这就是通过减去z+得到得平衡分离时,我得到的能量体系。

So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.

我们知道我们总是希望使我们的系统,处于能量尽可能低的状态，因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低，相较于分开时。
