dead-end main

There is a whirlpool or dead zone below the main water flow zone when the flow changes and the size of which is related to flow but its location basically unchanged.

当流量在一定范围内变化时，主流区下方均有漩涡低速区或死水区，该区域的大小与流量有关，其位置基本不变。

The results show that the new type of proportional direction valve is of good steady state control characteristics and equal displacement characteristics. The linearity of the control curve of the main spool displacement is well. However, there exists a certain neutral position control dead zone.

研究结果表明，新型比例方向阀的稳态特性和等位移特性良好，主阀芯位移控制曲线的线性度也较好，但有一定的中位控制死区。

Main steam temperature system is a typical open loop stable system with large time delay, its model can be described by an equivalent First Order plus Pure Dead Time ( FOPDT) type.

火电厂主汽温系统是典型的大滞后开环稳定系统，其过程模型可以等效为常用的一阶加纯滞后形式（FOPDT）。

And so the world forgets that the main business of Criticism, after all, is not to legislate, nor to classify, but to raise the dead.

于是世人遂忘记，批评的首要职务并不是去制定条律，也不是去做分类，而是去起死回生。
