变软的

There are some information about the development of soft switch and welding machine. There are also introduce some methods about the athwart invert current and how to realize it. At last we introduced the structure of DSP and how to design the module by software.

在本论文中首先介绍了软开关技术和电焊机的一些发展，然后介绍了几种典型的逆变电路和实现逆变的方法，最后讲述了DSP的硬件结构和模块以及控制软件的设计方法了软件中的模块。

Therefore, the structure could be stable. However, the structure was changed to amorphous when the strain level was over 15%. At the same time, the binding energy increased rapidly and the structure stability was reduced. During the deformation process, both the bond angle and bond length were significantly affected by the strain level.

这表明Ni纳米线的径向很软，结构之间几乎没有能量转换，且其稳定性基本不变；当压缩程度大于15%时，Ni纳米线结构变为无定形结构，它的结合能变大，且变化很快，表明其稳定性降低；压缩程度对Ni纳米线键角和键长的分布有着很大的影响。

Bow characteristic: Knew very well the open country seeks livehood the skill, excels to hunt for the wild animal; Is very high in the carte and tierce heaven share, but does not understand the true profound carte and tierce; Does not select food, most likes the fragrant barbecue, vainly hoped for eats each kind of different game; To mountain under world all and sentiment of the male and female ignorant chong ignorant, after when descends a mountain, often by own idea weight judgment, causes trouble and makes an ass of oneself all many; Thought the myriad things equality, the birth and death, the law of the jungle all are in society the habit, cannot have the idea which the monster and the human must oppose, the innate its package cares about; Meets matter of the trouble to be able to trade a direction to ponder that, does not like from seeking the worry, but regarding the matter which already recognized, processes very the straight line thought.

对山下世界一切和男女之情懵憧无知，等到下山之后，常以自己的想法衡量判断，闯祸和闹笑话都不少；认为万物平等，生老病死、弱肉强食皆是世间常态，更不会有妖和人必须对立的想法，自有其包容心；遇麻烦之事会换个方向思考，不喜欢自寻烦恼，不过对于已经认定的事，处理起来很直线思维。一个从小在山上长大的野人走出大山，软星设定的这个男主似乎并不稀奇，纯如白纸的男主多年来用的也不少了，但是软星为野人设定的对白和桥段让这个野人变得不凡，有的时候看到他的对白都不禁感叹编剧太有才了……初期和韩菱纱大量的搞笑对白自不用说，后期和慕容紫英谈到望舒剑的用途那段也让人笑喷。
