This paper introduces the use of polynomial fit in compensation for frequency response of a receiver, a good result is got, and the polynomial fit is a very useful tool.

通过介绍作者在工作中使用多项式拟合进行接收机频响补偿并取得的良好效果，说明多项式拟合是一种非常有用的工具。

The final parameters of PSS are further optimized and determined by field adjustment test, such as the frequency response tests with and without compensation and the step response test.

再通过PSS现场整定试验，即无补偿、有补偿频率响应特性及抗扰动试验再次优化并确定参数；

Equivalent mathematical model of frequency response function for externally pressurized spherical gas bearing with inherent compensation was built.

建立了静压气体球轴承气膜位移-动态力频响函数的数学模型。
