方差分析法 meaning in Chinese
method of analysis of variance
variance components method
Examples
- In this paper , we first analyze each factor of influencing threshing performance , and deficiency of all traditional methods such as single factor , orthogonal experiment , variance analysis and regression analysis , which have been used to study the threshing performance . in the basis of above analysis , we propose a new method of threshing performance modeling - a bp neural network . by use the new ways of threshing performance modeling - a bp neural network , we can obtain the optimum model of threshing performance , which can better describe the seed - husking plant ' s feature of complex nonlinear , multi - input - output and indefinite
本文首先分析了影响脱粒装置性能的各个因素以及传统研究脱粒性能的各种方法如单因素法、正交试验法、方差分析法以及回归分析法的缺陷，在此基础上提出了采用bp神经网络对脱粒装置性能模型进行优化，采用这种方法优化脱粒装置性能模型可以更好地刻划脱粒装置所具有的多输入多输出、复杂非线性以及不确定性等特征。 - As to the work about experiment study , at first , the paper makes certain the prominent affecting factors to the automating and humidifying property of this kind of nozzle by orthogonal experiment . by jicha analysis method and fangcha analysis method , the paper got that the nozzle aperture , the initial water temperature and the spraying pressure have prominent effect to the humidifying property while the effect of the original air state is small
试验工作方面，首先通过正交试验确定对撞针型高压小孔径离心式喷嘴雾化加湿性能影响显著的因素，运用极差分析法和方差分析法，得到喷嘴孔径、喷水初温和喷水压力对喷嘴的加湿性能影响显著，而待加湿空气初状态的影响相对较小。 - Abstract : based on the problems in assessments of quality of life and the theory of analysis of variance for split - plot design , a method for analyzing longitudinal quality of life data both univariate and multivariate was introduced with discussions on the application problems . it is also used to analyze the longitudinal quality of life in drug addicts across two groups
文摘:万崇华等.纵向资料裂区设计方差分析法及其在吸毒者生命质量评价中的应用.数理统计与管理. 1999 ， 18 ( 1 ) ， 1 - 4本文针对生命质量测评中存在的实际问题，分单变量和多变量两种情况介绍用裂区设计方差分析思想处理纵向生命质量资料的方法，对应用中的有关问题进行讨论，并用于吸毒者纵向生命质量的分析。 - According to the comparison result , the variance analysis will not be applicable when the allowance range has to be set flexibly according to specific operation requirements although it can achieve a high rate of fault detection . for example , when the allowance range of some particular component gets bigger , the variance analysis could not precisely define the new judgment boundary
比较后发现,方差特征分析法虽然可以达到很高的故障检测率,但不适用于元件容差需根据具体要求灵活设定的情况,例如当具体情况中某个元件的容差范围变大时,用方差分析法却不能准确地定出新的判断界限。
