析出物对IF钢性能的影响

一种阻性的晶闸管控制制动器被用于阻尼向串联补偿传输供电的热电发电机中的瞬态扭。重点放在开发适用的控制算，并通过多种不同的运行方式验证算法。作为一种制动器最优控制的可能方法，本文研究了离散等级一般化预先控制（ＧＰＣ），讨论了系统上ＧＰＣ执行过程中存在一些问题。用Ｐｒｏｎｇ分析来辩识系统传递函数，此传递函数与控制方案的考虑及强度特性有关。

EFFECT OF PRECIPITATES ON THE PROPERTIES OF IF STEELS

To achieve interstitial-free steel, sufficient amounts of strong carbide-formingelements such as Ti and/or Nb,are necessary to stabilize carbon even in extra-low carbon steel.However,the required amounts of these elements change with the amoumts of carbon andnitrogen. In this paper,the precipitates of carbon and nitrogen in IF steels have been investigated,and it has been found that precipitates have an important effect on the properties of the material.
