偏流的近似计算与分析

A Formula for Approximate Calculation and Analysis of Drift

本文推导了一个计算偏流的近似解析公式。公式的物理意义明显,能正确反映物理量与偏流的关系。因而公式也可用于分析各因素对偏流和方向散布的影响。文中通过实际算例表明公式的精确程度也是令人满意的。

An analytical formula for estimation of drift is given in this paper. This formula has evident physical meaning, and shown the relationship between the physical parameter and the drift, so it may be used to analyse factor influencing drift and cross-disperion. The results of the examples show that the accuracy of the formula is guite good.
