The preformed aluminophosphate precursor was obtained after the gel was heated at 423 K for 4 h in an autoclave.

该 预制铝前身是获得后凝胶加热423 K时为4小时，在一个反应釜。

For example, the diameter of a bar can be increased by heating and hammering axially.

例如，棒料的直径可以通过加热和轴向锤击而增大。

The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

纵观目前的永磁无刷直流电机的无位置传感器控制方法，比较成熟而可行的方法多集中于电机在中高速区域运行时，能够较准确估计转子位置；电机处于低速、极低速、静止状态时电加热管，因为反电动势幅值较小或者为零，而无法正常工作。
