he upper-bound model of cross-wedge rolling with central bursting was proposed in this paper.
在楔横轧载荷上限法模型基础上加入曼内斯曼缺陷的典型方式—中心开裂，建立了楔横轧中心开裂上限法模型，在此基础上对楔横轧中心开裂的发展规律进行研究。
Transient Rotate Speed Meter of Motor for the Centrifugal Switch s Breaking Away;
电机离心开关断开瞬时转速测量仪
A New Type of Meter for Measuring Switching-off Speed of Motor s Centrifugal Switch;
一种新型的电动机离心开关断开转速测量仪
When the motor is started up to a fairly higher speed,the centrifugal switch will automatically make the rotor winding to be short circuit so as to be operate normally.
将转子绕组分为两段，并进行绕组移相改接，即可达到减小起动电流与增大起动转矩的目的，通过离心开关自动地将转子绕组短接后便可进入正常运行。
