In addition the brittleness and effect of heat treatment in magnetic field have been greatly improved and the grain size becomes smaller.

钒元素还有细化晶粒的作用，并能改善脆性和磁场热处理效果。

The results indicate that, with the increase of rolling times, the grain size becomes smaller, the content of sorbite multiplicates, and the yield strength improves.

结果表明，随轧制道次的增加，晶粒尺寸逐渐减小，索氏体的含量不断增加，屈服强度逐渐提高。

The smaller feature size and the new appeared structures bring some new problems. The design of electrostatic discharge (ESD) protection devices becomes more and more different.

但是在器件特征尺寸的缩小以及新颖结果的出现的同时，不可避免的会带来一些负面的影响，其中静电放电保护器件的设计就变得越来越困难。
