Elastic collisions deplete very little of the electron's energy . 彈性碰撞中電子減少的能量非常少。
As neutrons pass through matter, they make occasional elastic collisions with nuclei . 當中子穿過物質時,偶爾與核發生彈性碰撞。
Additional insight is gained by examining the elastic collision of equally massive particles in the center-of-mass frame of reference . 對質量相等的兩質點的彈性碰撞更徹底的理解,可通過質心參照系而獲得。
As neutrons pass through matter , they make occasional elastic collisions with nuclei 當中子穿過物質時,偶而與核發生彈性碰撞。
It is well known that the problems about the elastic collision of two bodies in 2 - d space can not be exactly solved generally 摘要眾所周知一般說來,關于兩個物體的彈性碰撞的一些問題無法被確切解決。
