牛顿运动定律应用于质点时就得到这样一个著名的向量方程式： f ma - A few months later , karl schwarzschild gave the solution for the gravitational field of a point mass , showing that something we now call a black hole could theoretically exist
几个月之后，卡尔?史瓦西给出了点质量引力场解决方法,表明我们现在称做黑洞某物理论上可以存在。 - In effect , bodies are assumed rigid and treated as point massed ; sprigs are massless and electrical leads resistanceless , suitable corrections are made to the system mass or resistance ; temperature are uniform ; etc
在效果上，物体被假设为是刚体并且质量都集中在一点上，弹簧的质量可以忽略；导线的电阻为零；或者是可以得到合适的关系式使得系统的质量、电阻和温度的分布是均匀的。 - This paper is developed a algorithm to generate airplane ' s 4d approach trajectory , by using fourth order runge - kutta , based on a set of point mass equations of motion , pilot procedure and air traffic control procedure
本论文是基于飞机质心运动方程组，结合飞行操作程序和空管管制程序，根据飞机的空气动力学模型、推力模型和实时的大气气象模型，用四阶龙格? ?库塔积分法规划出飞机下降进近4d轨迹。
