例句
- This timing is affected by the relationship among poppet weight, spring rate, poppet travel distance, plunger speed, and plunger diameter.
定時(shí)受提升閥重量，彈簧振頻，提升閥閥程，活塞速度以及活塞直徑的影響。 - The additional benefit of lifting the plug is the low friction and low torque required to cycle the valve.
提升閥塞的其他優(yōu)點(diǎn)是循環(huán)操作閥門(mén)所要求的低摩擦和低扭矩。
