原生晕分带序列研究方法综述

分带性是原生晕的最重要特征，分带指数法是应用最为广泛的计算轴向分带序列的方法之一，针对该方法中存在的缺陷，提出了多种新的方法，重心法以每个元素异常浓集重心的空间位置排出分带序列，同时适用于轴向分带和横向分带序列的计算，克服了其它方法中存在的缺陷，是一个很有应用前景的方法。

A Summary of Studying methods in Primary Halo Zoning Sequence

The zoning sequence is the most important feature of primary halo,and thezonal index method is one of the most widespread method,and considering the defects of themethod of zonal index, a new method has been put forward. The method of barycenterdetermines the zoning sequence by using the space position of anamalous concentrationcenter for each element,and it can be used in the calculating the sequence of axial zoning andtransversal zoning,and could correct the defects of other methods, therefore it is a usefulmethod.
