多因素试验 meaning in English
multifactorial experiment
Examples
- In order to restrict the displacement of relaxed rock effectively , the factors affecting the efficacy of anchor measures are analyzed according to mechanism of action of anchor . in terms of principle orthogonal design , the influence of parameters of anchor to displacement of excavation slope are elevated by computing using finite element method simulation , and the optimal scheme of anchoring parameters including length of anchors and space between bolts and thickness of shot concrete are defined . finally , the optimal scheme of anchor parameters are determined with considering results of theory analyse and numerical calculation , which provide theory bases for engineering
为了有效防治边坡开挖后岩体的松弛变形，根据锚杆的作用机理对影响锚固效果的主要因素进行分析，并利用处理多因素试验的科学方法?正交设计原理，以有限元数值计算为手段，以有效约束边坡开挖位移为标准，评价了锚杆长度、锚杆间距、混凝土喷层厚度等锚固参数对边坡变形的影响大小和规律，经过比较分析最终提出了锚固参数的优化设计方案，为工程设计提供了理论指导。 - By analyzing the biodegradable engine oil ' s demands on the lubrication mechanism and biodegradable performance , base oil and some additives are chosen scientifically and reasonably . the uniform design of experiment is used for arranging multi - level and multi - factor experiments . the stepwise technique is adopted to put forward the regression equation
通过分析可生物降解润滑油在润滑性能和生物降解性能两方面的要求，合理的选用基础油和添加剂，并引进均匀设计方法，合理的安排多水平多因素试验，用逐步回归对试验结果进行处理，得出回归方程，以此分析基础油对添加剂的感受性、添加剂间的配伍性。
