摘　　要：借助作者研究的一种可求超越方程和高次方程近似解的“对数校直法”，推演了由气口比时面值计算其配气相位角α和Δα的近似计算公式．在现有二冲程机应用的α角和１／λ值范围内，其相对误差不超过±１．０％．With the help of “logarithm alignment method” which is developed by the author and used to extract the approximate root of transcendental and high degree equations,the author deducts the approximate formula for calculating timing angle α and Δ α from the specific time area value of the ports.Its relative error is not larger than ±1.0% within the value of angle α and 1 λ used in current two stroke engines.
