So we want to do experiment about the roles of self - regulation and type of feedback in calibration study . the experiment design is : 3 ( achievement feedback , outcome feedback cortrol ) x2 ( high self - regulation , low self - regulation ) x2 ( male , female ) . the tasks include standard task and comparison task 本研究的实验设计采用3 (成绩反馈组、结果反馈组、控制组) 2 (自我调节水平高、自我调节水平低的两组学生) 2 (男、女)的组间设计,所用的实验材料分为标准材料和对照材料两种。
Thirdly , the contents should be organized . arrang the inorganic chemistry experiments , organic chemistry experiments and analytic chemistry experiments in a whole , and in order to make the experimental teaching more systematically , they should be separately organized as these parts : basic knowledge of chemistry experiment , basic operation experiment , experiment of chemical quality , qualitative experiment , quantitative experiment synthesis , extration and experiment design 三是内容的组织,将无机化学实验、有机化学实验和分析化学实验整体编排,按化学实验基本知识、基本操作实验、化学性质实验、定性实验、定量实验、制备和提取及设计实验等分块组织,以利于更系统地进行实验教学。
On the basis of the finite element analysis of the press - mounting machine , to solve the modeling error of the previous modeling method , a new mixed - model method using the spring element and thin - layer solid element was introduced in this thesis . an experiment designed to test the interface static stiffness was carried out and the needed modeling datum was obtained 在对压装机进行了整体建模仿真的基础上,针对压装机整体建模存在的误差问题,本文提出了一种改进的弹簧单元和薄层实体单元混合建模的方法,并依此设计了螺栓结合面静刚度测试试验,通过试验获得了建模所需的参数。
In the experiment design , comparison samples are modeled , cured and tested at one time for reducing deviation , and w / c are choosed from 0 . 6 to 0 . 26 , test pressure frome 0 to 4mpa for covering test area . the conductivity of concrete is tested during the permeability to describe permeability process in detail 在设计方案中,采用对比样同时成型、同时养护、同时测试,以减小差异;选择水灰比在0 . 26 - 0 . 60之间,压力范围在0 - 4mpa之间,覆盖可测试区间;测试加压渗透过程中混凝土的电导率,描述渗透过程。
This article describes the development process of surrogate models and introduces some experiment design methods and approximation approaches that can be used for a mdo surrogate model , they are full factorial experiment design , orthogonal experiment design , uniform experiment design , central - composite experiment design , and polynomial response surface method , kriging method , radial basis function method and artificial neural network 为此本文中分别介绍了正交试验,均匀试验以及中心复合试验等几种试验设计方法,以及多项式响应面, kriging ,和径向基函数等几种数学近似方法。并且通过构造描述机翼展向升力分布的代理模型,对上述几种方法作了对比分析。
