摘要
通过引进变量代换和级数求和法得到ｌｎ２的若干新的渐近展开式，并且比较了计算ｌｎ２的收敛速度。所得结果有利于计算和判断收敛速度，对估计ｌｎ２近似计算中的误差提供了依据。
In this paper, some new asymptotic expansion formulas of ln2 are obtained byusing the substitution of rariables and summation method of the series and then the conver-gence rates of calculation ln2 are compare with each other,The results obtained are of ad-vantage for calculating and judging the convergence rate and provide a basis for estimation-the error in the approxinfate calculation of ln2.
