...常数,故数学模式中通常会给予两种与时间有关之条件,亦即物体之初始位置 (Initial Position) 0 y 和初始速度(Initial Velocity) 0 v ,因此问题之初始条件为: ( ) 0 0 y y = 、 ( ) 0 0 v dt dy = (4) 式(3)与式(4)即构成强制振动问题之数学模式。

The influence of compiling method, element division, initial velocity field prediction and the other parameters on the computing speed were discussed. The computing speed has been improved and the calculating time has been shortened in a certain extent.
此外,研究了编译方式、单元划分、初始速度场设定和相关参数对计算速度影响。

逃逸速度就是一个物体的速度,比如说,从加农炮中射出的最小初始速度,这样这个物体以后就可以自己脱离地球的引力。
Escape velocity is simply the speed of an object that's shot out of a cannon the minimum initial speed so that the object could later escape Earth's gravity on its own.
就是初始速度,而第二项是。
请看我们的例子里的t1和,请注意初始速度为。
t2 In our case, t1 to t2 here 0 notice the velocity is zero as a start.
I released a piece of candy, threw it from my hand, and the initial conditions have to do with where did I release it and with what velocity.
我从我的手中抛出一颗糖,初始条件就是,我从什么位置抛出的,以多大速度抛出的
They tell you the initial location and initial velocity of the object.
它们表示的是物体的初始位移,和初始速度
So,the point is,every object falling under gravity is given by the same formula, but there are many, many objects that can have many histories, all falling under gravity, and what's different from one object and the other object is, when was it dropped, from what height, and with what initial speed.
关键是,每一个受重力作用下落的物体,都有同样的表达式,但是各个受重力作用下落的物体,都有不同的初始条件,所以它们的区别在于,下落时刻,下落高度和初始速度
