摘　　要：Gauss消去法对数据没有任何的要求,即弥补了迭代法的缺陷;在消元过程中避免了误差的产生,只要在回代中的除法能除尽,就能得到精确解;如在回代过程中的除法不能在允许的范围内除尽,采用分数回代也能得到相当精确的近似精确解。本算法在成矿预测中能起到非常好的作用,文章用该方法研究广东下庄铀矿田岩层中部分微量元素对铀成矿的影响。There is no any requirement for Gauss elimination operation that not only remedies the iteration but also prevents the error from the elimination. So long as it can be divided exactly for back substitution the accurate solution can be obtained. If it can not be divided exactly during back substitution in the permitted range adoption of fractional back substitution would result in the approximate accurate solution. The method is effective for ore prediction. This paper uses the method to deal with influence of some micro-elements in the strata of Xiazhuang uranium ore field on uranium ore formation.
