will level control to 如何理解? continue to pump d-1 to the deepwell and d-2 to d-3, (d-3 will level control to d-1) until the unit is lined out and we are sure we are not getting significant amounts of liquid to the flare. 说明:d-1向深井泵送废液,d-2向d-3泵送废液,d-1和d-3没有直接关系,d-1和d-3到底是谁控制谁? pump d-1 to the deepwell是d1向深送废液,那么d3 level control to,为什么不可以理解为d3液位控制d-1?我认为d-3用来控制d1 以上各位给出有关串联、联锁,不知道是从哪个词上得到的启示? 并联:parallel 串联:series 联锁:lock level在这里,是液位的意思。查看更多
