一个改进的计算饱和烷烃回转半径的经验公式

AN EMPIRICAI FORMULA OF IMPROVEMENT FOR CAICULATION OF PARAFFIN GYROIDAL RADIUS

本文以 Wiener拓扑指数为基础 ,结合分子密堆积信息指数 P3,分子支化度参量P2 ,提出了一个新的计算饱和烷烃回转半径的经验公式 ,计算结果显示 ,其相关性优于任碧野〔1〕文经验式 .

This paper puts forward a new empirical formula for calculating of Paraffin Gyroidal Radius on the basis of topological index Wiener. The index combines with the information index P\-3 and P\-2 and characterizes the structure of organic compound .Regression analyses show that the formula has better correlativity than Ren's .
