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.

然而，农民们为了提高农作物的产量而广泛地过度使用化学肥料，使得相当量的肥料不能被植物所吸收。

These circumstances are usually caused by unavailability of various equipment units or subsystems.

这种情况往往是由于设备的某些部分或某些子系统不能继续使用而引起的。

Void unlink{ auto_unlink_hook :: unlink;}bool is_linked{ return auto_unlink_hook :: is_linked;}//The list can't have constant-time size!

定义一个使用基类钩子保存值的链表，该链表不能有常量时间的size函数！

When it comes to your health and your well-being, you must be unyielding in your decision to use condoms.

当涉及到你身心健康的时候，你一定不能在使用避孕套的决定上屈服。

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。

These adjustments will take account of the dilutive or concentrative effect necessary to preserve the economic equivalent of the rights and obligations of the parties under the relevant margin trade immediately prior to that event.

当您使用电话或互联网通讯指示我司开始或结束合约时，该通讯不能在我司确定您的指示被执行前，因为某些超出我司控制的情况而被中断

However, this method is discommodious and can not get the instantaneous transformation of dust concentration.

摘 要：环境粉尘浓度的测定一般使用滤膜称重方法测得，该方法费时费力，且不能得到瞬时粉尘浓度的变化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
