以不完全Γ函数比用作固定床透过曲线的近似解

APPROXIMATE SOLUTION OF BREAKTHROUGH CURVES IN A FIXED BED USING INCOMPLETE Γ-FUNCTION RATIO

以不完全Г-函数比近似固定床透过曲线,适合于各种模型,对于多釜串联模型尤佳。经对几种不完全Г-函数近似解的比较,认为本文推荐的方法适用性广,并有足够的精度。

It is suitable for all models, esp. CSTR model, to use the incomplete Γ-function ratio as the approximate solution of the breakthrough curves in a fixed bed. The comparison amoung several approximating methods for solving incomplete Γ-function shows that the method proposed has the high applicability and enough accuracy.
