1) average life of well
井的平均开采期
2) production life of a well
井开采期
3) mean temperature of heating period
采暖期平均气温
4) non-commercial well
无开采价值的井
6) average switching period
开关周期平均法
1.
Using the method of average switching period an average model of three-phase PWM rectifier (VSR) is set up; separate the disturbance obtained the steady-state model and small-signal model.
利用开关周期平均法建立三相电压型PWM整流器(VSR)的平均模型,扰动分离后分别得到稳态模型和小信号模型,其小信号模型即为线性时不变模型。
