The relationship between the error signal and gain parameters of PID controller is nonlinear, and , a normal controlled system＇ s step response figure , under the condition of ideal change of the three PID gain parameters in the different time , PID con troller.

但是，目前使用的PID控制器大多仍是传统的线性PID 控制器，其控制信号是通过将参考输入与被调节量的偏差及其微分、积分进行简单的线性组合来生成的，而且PID控制器的增益参数在系统动态响应过程中是固定不变的，不能反映偏差信号的变化l2j。

Result The results showed that for the causes why tuckahoe cultivation field cann't be used successively, the change of organic matter, available N, available P, available K in the soil could almost be excluded, the decrease of pH value was likely one. The number of Blattodea increased in evidence, but the further study must be required to elucidate the causality.

结果］结果表明，对于茯苓栽培场不能连续使用的原因，有机质、速效氮、速效磷和速效钾的变化可以排除；pH值有明显下降，推测是重要因素之一；蜚蠊目昆虫数量有明显增加，其因果关系尚需进一步研究。

However, the widespread overuse of fertilizers, containing nitrogen and phosphorus by farmers to increase their crop yields, has led to significant quantities being left unabsorbed by plants.

The forward results show that the surface response is different when using vertical line source and slant source for the same model. we shouldn't consider slant well as vertical line source in practical application.

正演结果表明相同模型使用倾斜线源和直线源其地表响应有较大的差别，实际应用中不能将井斜较大的井当作垂直线源，而应以倾斜线源处理。
