Comparing the ratio of standard deviation to the average for these two distributions shows that they are similar.
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）。
According as compare of voltage deviation and its variable ratio, optimal control of voltage and current is realized with querying fuzzy control sheet and adjusting adverse variable pulse width.
比较电压偏差及其变化率，查询模糊控制表，调节逆变脉宽，可实现电压及电流的理想控制。
The comparison result of computation value and measure value shows that their deviation is within 3% for low load ratio, and has increasing tendency for high load ratio, but it is within 5%.
对于较小的负荷变化率，压力计算值与测量值偏差小于3%，而较大的负荷变化率时，偏差有增大趋势，但其误差小于5%。
