It depends on the length of delaying closing the valve plate to conduct the varying capacity and avoids some useless work , maintains the work ratio in a little range . in a word , it saves some energy 此调节系统根据延迟吸气阀关闭时间的长短确定排气量的大小,从而避免了压缩机作无用功,在压缩机气量变化的情况下,维持比功率(排气量与功率之比)几乎不变,从而节约了能耗。
The coach ' s intrinsic value and extrinsic value could predict 18 . 1 % of variance of working ratio orientation , and the intrinsic value could separately predict 38 . 3 % and 3 . 6 % of working identification orientation and working achievement orientation . 4 3 .教练的内在价值及外在价值能有效预测其工作比重取向的变异量达18 . 1 % ,而其内在价值可以分别预测其工作认同取向及工作成就取向的变异量达38 . 3 %及3 . 6 % 。
