The livestock sector is probably the largest source of water pollution, contributing to eutrophication, 'dead' zones in coastal areas and degradation of coral reefs.
畜牧业很可能是水污染的最大来源，造成富营养化、沿海地区出现“死区”和珊瑚礁退化。
Dead-time effects can be regarded as a kind of space-vector, which is determined by two factors: sector number and direction of phase current.
死区效应可被视为一种空间矢量，它由两个因素决定：扇区数和相电流方向。
The relationship between the dead-time voltage sector and the stator current sector is analyzed and a method for compensating the stator voltage sector is proposed based on the reconstructed current.
分析了死区电压矢量和定子电流矢量的关系，由此得到一种根据重构电流矢量来补偿定子电压矢量的方法。
Sometimes the negative pressure control system of boiler in power plant contains a strong nonlinear sector such as dead-zone which makes the system oscillate.
火电厂炉膛负压控制系统中有时含死区类的强非线性环节，死区使该控制回路产生振荡，仅用常规pid控制器无法克服这一现象。
