单相电动机运转时,产生与运转方向逆方向的转矩,因此不可能在短时间内改变方向。
Unlike tracing requirements to use cases, tracing in the reverse direction is often overlooked, but we accomplished this easily in Rose.不像跟踪需求到用例,反方向的跟踪经常被忽略,但是我们可以很容易的在Rose中完成这一点。
As the winds reverse direction (offshore versus onshore), they alternately enhance or suppress upwelling, which changes nutrient concentrations.由于风向会发生反转(离岸与陆上),它们通过加强或抑制上升流的交替,从而改变养分的含量。
