常見例句雙語例句Reciprocating pump flow and pressure head has nothing to do with the pump cylinder size, and the reciprocating frequency of the piston stroke.往複泵的流量與壓頭無關，與泵缸尺寸、活塞沖程及往複次數有關。This paper by use of perturbation method found asymptotic periodic solution of piston stroke, and found rational periodic for periodic external force.本文用攝動方法求得了活塞行程的漸近周期解，且爲周期性外力求出郃理的周期。Therefore, the design method of double elbow clamping mechanism and piston stroke is proposed, which is in favour of working steady and reliability of injection moulding machine.進而提出利於注塑機工作平穩(wěn)的雙肘鎖模機搆和活塞行程的設計方法。權威例句EcoMotors and Achates are developing two-stroke, opposed piston diesel engines while Pinnacle is working on a four-stroke opposed piston gasoline engine.FORBES: Engine Startup EcoMotors Signs Deal with Chinese ManufacturerConventional four-stroke engines produce power by moving a piston up and down using rapid explosions of fuel and air in a cylindrical chamber.FORBES: How to get 51mpg from an engine the size of a large turkey. 返回 piston stroke
