The ( hbnceptiori of equivalent weight is put forward to build the model of rotary kiln " s axial movement by using the law of conservation of momentum 提出了當量質(zhì)量的概念,運用動量定律建立起回轉窯軸向運動速度模型。
When the motion tracks of two objects intersect , they may collide and have interference . before and after their collision , they meet law of conservation of momentum and law of conservation of energy 兩個物體的運動軌跡相交時,將發(fā)生碰撞、干涉,在碰撞前后滿足動量守恒和能量守恒定律。
When the author sets up the mathematics model with describing the process of two - dimensional debris flow , he develops the continuity equation by the law of conservation of mass and establishes the momentum equations by the law of conservation of momentum . the author makes full use of the advanced computer technologies , establishes the finite difference equation of numerical simulation by the differential operator fission method , and writes programs for computers which contact friendly with the other programs . the parameters are directly input on the keyboard 在泥石流堆積數(shù)值模擬方面,作者以前人工作成果為基礎,在建立數(shù)學模型時,根據(jù)質(zhì)量守恒原理,推導建立了泥石流連續(xù)性方程,根據(jù)動量守恒原理,推導建立了泥石流運動方程;在數(shù)值解法上,充分利用高速發(fā)展的計算機技術,采用算子分裂法建立數(shù)學模型的差分格式,開放式編制程序,人機對話方式設置參數(shù),計算機程序具有通用性、可擴展性和易維護性。
