分析了地震加速度时程模拟的常规方法，指出初始加速度时程的选取十分重要。

The normal method to simulate earthquake acceleration time history is analyzed, and it is shown clearly that choice of initial acceleration time history is important.

由于撞击夹刀块的能量包括爆炸气压和冲块的动能两项，所以夹刀块能获到很大的初始加速度。

Since the energy which strikes the tool holder includes the explosive gas pressure and the kinetic energy of the moving plunger, thus a high initial acceleration of the tool holder is obtained.

对常规方法构造初始加速度时程的方法作了改进，并建议直接使用真实地震加速度时程记录作为初始时程。

The method making initial acceleration time history in the. Normal method has been improved, and it is recommended to use real earthquake acceleration records for initial time history.

Simply knowing the acceleration is not enough to tell you where it was at the initial time.

仅仅知道加速度是,不足以告诉你它在初始时刻的位移的

So, we know in this example the initial height should be 15 meters and the initial velocity should be 10, and for acceleration, I'm going to use -g and to keep life simple, I'm going to call it -10.

我们知道在这个例子中,初始高度为15米,初始速度为10,然后是加速度,我们用"-g"表示重力加速度,为了计算方便,加速度的值取为-10
