pressure ratioとは 意味・読み方・使い方

These pressure ratios are compared with each other, and when P_2/P_1≥Rmax, the pressure ratio is set to the maximum pressure ratio Rmax based on the flow velocity (S9).例文帳に追加

A pressure ratio calculation means 160 calculates the target intake pipe pressure of a pre-set intake pipe pressure absolute pressure and the pressure ratio of the intake pipe pressure after a throttle valve is continuously kept at a specified opening or higher for a specified time.例文帳に追加

圧力比率算出手段１６０は、絞り弁開度が所定開度以上を所定時間継続後に、予め設定した吸気管圧力絶対圧の目標吸気管圧力と、吸気管圧力の圧力比率を算出する。 - 特許庁

As the hydraulic pressure control of the secondary pressure and the primary pressure is performed under the reduction ratio-limited secondary pressure and the reduction ratio-limited primary pressure having a gentle reduction gradient by limiting the reduction ratio, the generation of the undershoot on the actual secondary pressure and primary pressure can be prevented.例文帳に追加

減少率に制限が加えられ減少勾配が緩やかになった減少率制限セカンダリ圧および減少率制限プライマリ圧をもとに、セカンダリ圧およびプライマリ圧の油圧制御が行われるので、実際のセカンダリ圧およびプライマリ圧にアンダーシュートが発生することが無い。 - 特許庁
