For bulk materials , non - normal distributions are generally found after routine plotting of histograms of process data . quality indices should not be computed because the values obtained may be misleading 对于散装材料,在绘制常规的过程数据直方图之后,如发现呈非正态分布,由于所获得的值可能引起误导,所以不应计算质量指数。
Since in many situations the error term is not normally distributed , it is important to know the asymptotic properties ( large sample properties ) , i . e . , the properties of ols estimator and test statistics when the sample size grows without bound 由于在很多情形下误差项可能呈现非正态分布,了解ols估计量和检验统计量的渐近性,即当样本容量任意大时的特性就是重要的问题。
Based on survey data from some researches , dead load model and vehicle load model are presented in this paper . it is quite evidence that dead load model is gaussian distribution , and vehicle load is non - gaussian distribution , which operates general traffic and rush hour traffic states 本文在国内外各种调查资料的基础上,分别引入恒荷载模型及车辆荷载模型,其中恒荷载呈正态分布:车辆荷载则为非正态分布,并将其分为一般运行状态及密集运行状态两种情况,分别建立服役期最大值分布函数。
At last distribution functions of load modes in life service are presented . based on the resisting force model and load model , the limit state equations of rc bridge are formulated . according to the resisting force is time - dependent and vehicle load is the non - gaussian distribution , jc method is applied to calculate the time - dependent reliability index of rc bridge 在抗力衰减模型及桥梁荷载模型的基础上,将可靠度理论引入桥梁结构的评定中,推导出了桥梁结构耐久性极限状态方程,并根据耐久性极限状态方程中抗力是时间的函数,以及车辆荷载为非正态分布的特点,应用当量正态法( jc法)编制相应的程序计算桥梁构件的时变可靠度指标。
