摘要
目的 :为把煎药过程中的加水量控制在一定的范围内 ,寻找到一种简便、快捷、合理的方法。方法 :随机抽取门诊处方50张 ,进行加水及煎煮实验 ,从而测定平均蓄水系数、平均吸水系数及蒸发量。并用t检验法进行实验分析。结果 :使误差降到了5 %左右 ,避免了煎药时加水的盲目性 ,保证了煎药的质量。结论 :加水量与吸水系数、蒸发量有关 ,与蓄水系数无关。加水量可通过公式 :(吸水系数 *药重 +蒸发量 +所需药量 )
Objective:To look for a rapid,simpleand rational method to determine the amount of water to be added in decocting herbs.Methods:Experiment on the amount of water and deˉcocting in50selected prescriptions.The average amount of sluice,the average absorption coefˉficient and the amount of vaporing have been calculated.Results:The error rate was about5%.This method could curb blindness in amount of water added and ensure the quality of deˉcoction.Conclusion:The amount of water is correlative with the average absorption coefficient and the amount of vaporing,does not correlative with the average amount of sluice.
