When the speed pulse signal is provided, a calculation of the speed curve is achieved using first order digital differential method and the lease square of five points three times smoothing approach.
对于有转速脉冲信号的情况，实现了基于一阶数字微分和最小二乘五点三次平滑方法的转速曲线计算方法。

In the problem of smoothing, filtering and predicting matching data in aerospace measurement, matching data refers that velocity parameter is differential of position parameter.
讨论了匹配测量数据的平滑、滤波和外推问题。所谓匹配测量数据是指位置参数和速度参数呈求导的匹配关系。
