应用计算机系统评价复混药剂的实用程序

A Practical Program of Using Computer System to Evaluate the Mixture Insecticide

应用ＢＡＳＩＣ语言编制了评价复混药剂的实用程序，并对共毒系数的计算公式加以修改与完善。以ＬＣ９０值作为更重要的评价依据，采用共毒系数简化泛式：ＣＴＣ＝１００／混剂ＬＣ９０／∑（混剂中单剂含量／单剂的ＬＣ９０，精简了运算步骤，提高了运算速度和试验精度。

The paper deals with the practical program to evaluate the mixture insecticide in BASIC language,the calculate formula of cotoxicity coefficient is modofied and consummated.Based on the most important quota,LC90,the general formula is as follows:CTC=100/LC90 about the mixture/A,where A means the sum of the ratio between the content and LC90 of the single.This program simplifies the calculate steps,raise the calculating efficiency and the precision.
