骨骼肌收缩曲线的灰色建模研究

A Study on Grey Model of Contraction Curve of Musculi Skeleti

在骨骼肌非单调变化曲线的单调增与单调减变化的转折点处分段，分别建立灰模型。残差检验表明该模型的精度优于全数据序列建立的灰模型，并得出结论：单调变化曲线的灰模型能很好地反映骨骼肌收缩曲线上升期和缓慢下降期的发展变化过程，序列的分段、联合是提高非单调变化曲线的灰模型精度的一种有效方法。

Non-monotone curve of the musculi skeleti is divided into two parts at the turning point between monotone increasing and mono- tone decreasing. The precision of the grey model built on every part, tested by error, is superior to that built on the all numbers.The conclusion is that the progressing process of increasing period or decreasing period that belongs to the contraction curve of mus- culi skeleti can be exactly reflected by grey model of monotone curve, and dividing and combination of the series is an effective method that improves the procision of grey model built on non-monotone curve.
