摆动指数

构建的方法是通过定性和定量相结合的方式，利用路段摆动幅度指数和各类敏感区的权重，计算路段敏感性指数，将各种生态敏感区对公路网规划和实施的约束性量化。

The new method calculates section sensitivity index using of road swing index and various types of sensitive area weight .

灰色摆动序列经过动态指数变换具有灰指数特性，对变换后数据序列建立GM（1,1）可以进一步提高预测精度。

In this paper , grey wobbly sequence takes on grey exponent character by an especial dynamic exponent transformation . After that , if GM ( 1,1 ) for the transformed sequence is set up , the forecasting accuracy is improved more .
