相控阵雷达的天线阵面是整个雷达系统的重要组成部分，阵面中移相驱动器的移相精度是保证雷达系统测量精度的重要依据。
The antenna array is an important department of phased array radar system. The phase accuracy of shifter is necessary to the radar′s measurement accurate.
传统方法采用风机通风进行降温控制，使阵面中温度变化范围较大，造成移相驱动器的移相误差加大，影响雷达天线的性能指标。
The traditional method is using the blower to decrease the temperature, which will make the change of the temperature in wider range and larger the error of the shifter in the array system.
在光学精密测量中，PZT常作为移相驱动器用于各类干涉仪，作为纳米精度的微位移执行器驱动各种精密平移台，以及用于精密位移或压力传感器等。
In the measurement of optical, PZT is often used as driving machine to the interference instruments, then the nonlinearity should affect the precision of the measurement.
