| 摘 要： | 用穆斯堡尔谱学研究了河南西峡铬铁矿３个矿物样品。两个铬铁矿的谱被拟合成３套双峰，一个谱被拟合成４套双峰。然后用次近邻效应和Ｂ位上阳离子二项式分布计算结果解释了出现３套或４套双峰的原因。

| Abstract: | In this paper we studied three samples of chromite found in Xixia,Henan by using Moessbauer spectra.Two spectra of the chromite were fitted by three doublets;another was fitted by four doublets.Then we explained the cause for three or four doublets with next nearest neighbor effect and the results calculated in terms of binomial distribution in B site cation. |
