The Hamiltonian equation provides us an alternate description of the basic physical laws of motion, which is used to describe by Newton's Law. Newton定律是描述物体运动的基本定律,Hamiltonian方程则为运动的基本规律提供了另外一种表达。
Effect of alternate dry and saturated soil layers on ground motion and wave propagation 含水与不含水地层的分层交错对地面运动和波传播的影响
High-speed alternate motion leads to great friction between the contact surface of ball piston and cylinder and fatigue rupture such as material wear. 但由于高速往复运动,球塞表面与缸孔表面有极大摩擦,会造成材料磨损等疲劳破坏。
