3 . in " plan making and experiment design " process link , individual is the main factor result in students " difficulty . group and teacher are the second important factor and there is no significant difference between them ( 3 )在“制定计划与设计实验”环节,个体因素是导致学生困难的主要因素;小组因素和教师因素是第二位的因素,二者差异不显著。
Surrogate model is an important component of multidiscipline design optimization ( mdo ) . a surrogate model is created with experiment design methods and approximation approaches , and it can be easily integrated into a mdo framework 通过对比分析,我们认为要构造代理模型就必须引入能够大大减少试验次数的试验设计方法和能够解决高维非线性问题的近似方法。
An optimal robust design method based on experiment design approach and fuzzy mathematics is used to satisfactorily gain global optimal solution and the effectiveness of this method is verified by means of a practice 将试验设计方法和模糊数学知识结合起来,利用模糊数学中的隶属度函数及贴近度原则实现了这一多目标稳健设计的最优问题,并通过实例证明了该方法的有效性。
Application of the combined experiment design method to ethanol - water system has shown it ' s able to use for determination of the appropriate conditions for salt effect in extractive distillation with salt of binary close boiling or azeotropic mixtures 联合试验设计法在乙醇-水体系的应用表明:该法可用于二元共沸、近沸体系的加盐萃取精馏过程中盐效应适宜条件的确定。
In this paper , glycidyl ether , which was high epoxide value and low viscosity , was synthesized from 2 - trimethylene glycol , epichlorohydrin and the normal butyl alcohol by phase transfer catalyst based on the orthogonal experiment design 摘要采用1 , 2 -丙二醇、正丁醇和环氧氯丙烷为原料,在相转移催化剂的作用下反应,通过正交实验合成了的高环氧值、低粘度的混合醇缩水甘油醚。
