那平均加速度到底是多少呢？
所以在撞击的过程中,平均加速度,只有。
So therefore the average acceleration during the impact 5/ divided by one quarter...
求在这段时间间隔内平均加速度的数值。
Find the magnitude of the average acceleration during the interval.
所以如果把它代进来，会得到一个，小于0的平均加速度。
So if you substitute that in there you get an average acceleration which is smaller than zero.
角度在时刻t1到t2的过程中，增加了2，故平均加速度大于，看看这个角度。
The Angle increases, 2 so in our case from t1 to t2 0 the average acceleration is larger than zero Look at the Angle.
在t1和t2之间的，这段平均加速度2，等于t2时刻的速度2，减去t 1时速度，再除以。
The average acceleration 2 between time t1 and time t2 2 would then be the velocity at time t2 minus the velocity at time t1, divided by t2 minus t1.
所以速度的符号,和平均加速度的符号,这二者都取决于,这里x正方向,是如何定义的,和0点的选取没有关系。
So the signs in the velocity and the signs in average acceleration depend crucially on how I have defined my increasing value of x not where I choose my zero points.
可是如果考虑到,和t5之间的平均加速度5，between，t1，and，t5,那么它将小于,因为这里速度为,但是到了这里却是负值。
However, if you take the average acceleration t1 0 that is smaller than zero 0 because here the velocity is zero but here the velocity is negative.
通过比较台面上不同部位上几个关键结点耦合前后平均加速度值的变化，计算出了各个频率下的附加质量，并对附加质量给振动台设计带来的影响进行了研究。
Comparing with the accelerations of two different conditions, additional masses are calculated. At last, the influences carried by additional mass during the designing of vibration table are analyzed.
目前为止，是关于速率，平均速度和加速度。
All right, so far, about speeds and average velocities and accelerations.
把这一标准差和两次的平均值相比较，我们就能发现他们很相像，（因为我们知道重力加速度是个常数）。
Comparing the ratio of standard deviation to the average for these two distributions shows that they are similar.
高中毕业生的平均周收入以加速度增长，从1985年的40美元快速增至2005年的140美元。 。
Thee average weekly income of high school graduates increased at accelerated speeds, rising from $40 in 1985 to $140 in 2005.
平均速度——时间图表可以给出这个自由落体的重力加速度。
A graph of average speeds versus time can give the acceleration due to gravity of the falling object.
加速度计的偏置误差形成一平均的常值偏离加上一振荡分量。
