1·The weight of every index is determined by using the partial entropy weight, which integrates the subjective factors and the objective factors.

应用有偏好熵权法确定各指标的权重，综合考虑了主客观因素的影响。

2·Based on information entropy and mutual information, we proposed the definition of nonlinear partial autocorrelation.

本文在信息熵和互信息的基础上，提出了非线性偏自相关的定义。

3·For the mutual information calculated by partial volume interpolation method and Shannon entropy, certain local extremums are inevitable, which may lead to inaccurate registration.

采用部分体积插值法和香农熵计算得到的互信息，无法避免会出现一些局部极值，可能导致错误的配准。
