To established the optimum preparation condition orthogonal experiment was used comparing with the receiving of inclusion and oil content . tlc analysis was showed same between inclusion compound and volatile oil 摘要采用正交实验法，通过测定青蒿挥发油包合率和包合物产率测定油利用率、包合物收得率及含油率确定最佳包合工艺，并应用tlc对包合物进行定性分析。
Results : after we adopted uniform temperature acceleration to observe its stability laid aside for some time , we found out that the freeze - drying was stabler than water solution , its cycle of deposition was lengthened and uneasy to oxidize 结果：我们采取等温加速实验法对本品放置后的稳定性进行了观察、结果表明冻干剂较水溶液稳定，存放周期延长、不易氧化。
A general approach toward robust optimal design is proposed which is based on tolerance model and orthogonal experimental method , this method can deal with implicit and high non - linear functions and great variances in design variables 摘要结合容差模型和正交实验法的各自特点，提出了一种较为实用的稳健优化方法，该方法可以处理设计函数为隐函数或高度非线性函数，设计变量的容差可容许大些。
