A variable parameter value rolling grey forecasting model (RGM) is constructed, which makes an enhancement to the fixedparameter value RGM.
在固定参数动态灰色预测模型基础之上进行改进，提出了可变参数动态灰色预测模型。

Generally fixed quantity prediction method has a certain deficit because of the case that predicts a time moving parameter system with fixedparameter model.
一般的定量预测方法因用固定参数模型预测一个时变参数系统的情况而致存在一定的局限性。

This parameter is not a fixed number-the more intense the competition, the higher it can go, as the brain's fear centers progressively remove any restraint against performance.
