两种近似计算的比较

The Compatision of Two Formulas in Approximate Calculation

研究勒贝陶求积公式和高斯求积公式，在中子注量场的分布计算中，其余项随结点数ｎ和轴向距离Ｚ的变化关系．并给出它们在实际计算时应注意的条件。

This article discusses mainly the Gauss一integration formula and Lobatto一integrationrormula which are used in the calculation of neutron一flux field distribution,and the change-able relations of the two formulas′remainders with nodal point numbers n and axial dis-tance,The calculated conditions of the two formulas are also given in the paper。
