假设分布 meaning in English
hypothesis distribution
Examples
- There models are the three - parameter weibull , the normal , the extreme maximum value , and the extreme minimum value . three previous rules are taken into account to determine the appropriate models
根据误差数据的统计特点，指出了可能的假设分布有三参数weibull 、正态、极大值和极小值4种分布。 - ( 1 ) from the considering of the probabilistic model being actually established by randomness of the average relations fitting into the test data , the appropriated statistical distributions for the fatigue lives are explored by the errors , which is different from the commonsense
( 1 )概率s - n曲线本质上是在最佳拟合曲线(即均值s - n曲线)的基础上，考虑误差的随机性建立的。本文首次从误差数据的角度研究了疲劳寿命的良好假设分布模型。 - These rules consist of the total fit , the mathematics and fatigue physics , and the safety in tail predictions . an analysis of the test s - n data of 16mn steel weld joints reveals that the four models are reasonable if only considering the total fit as the conventional method did . but if by the present three rules , the appropriate models should be the normal or the extreme maximum value
根据先前提出的有限数据下良好假设分布的确定方法，包括三个原则，即假设分布形状与误差数据真实分布形状的一致性、预测的总体拟合效果、与疲劳失效机制的一致性和尾部预测的安全性，通过对线性均值s - n曲线拟合16mn钢焊接头s - n数据误差的统计分析，说明应用一般推断方法， 4种分布都可合理地作为数据的统计模型，综合考虑三原则后，极大值和正态分布是可能的良好假设分布。 - The minimum square method was used in regressing analysis for the result of treatment in a supposed distribution function , the " d " examination method was used for weibull distribution and index distribution , and obtained the distribution type in the life of the main shaft bearings , appraised the reliability life , the mean life and the reliability in 500hours of the main shaft bearings with theoretical distribution function
用残存比率法、平均故障法和累积故障法对主轴轴承可靠寿命进行了评估，用最小二乘法对现场数据统计处理结果进行了假设分布的回归分析，并用d检验法对威布尔分布和指数分布进行了分布检验，得出主轴轴承寿命分布类型。利用理论分布函数，对主轴轴承可靠寿命、平均寿命、 500小时的可靠度进行了评估。
