提出了数控系统中一种新的指数升降速控制曲线算法-加权补偿法，该算法用加权平均及权值修正技术，解决了数控系统中指数升降速控制曲线不能任意动态调整的难题。
This algorithm USES weighting mean and modified weight to solve the problem of that the exponential curve of acceleration and deceleration could not be dynamical adjusted freely in CNC.
方法 用季节预测法中的移动平均比率法计算趋势值与调整月指数 ，最后应用模型。
Methods The trend values were calculated and the monthly indexes were adjusted with moving average method of season prediction method, and then the model was applied.
