Through component score coefficient and percent of variance, the weight of evaluation indexes is gained.

该模型由因子得分系数和方差贡献率确定指标权重，然后以指标权重与各水样相应指标的标准化值进行加权平均得到水质评价的综合指标值，进而对评价样本进行排序和分级。

Longitudinal and correlated data are commonly modeled with generalized linear mixed models which contain both fixed and random effects. The source of the random effect may come from the genetic heredity, familial aggregation, or environmental heterogeneity. The inference of its variance component is usually difficult due to the dimension of its covariance matrix and the complexity of the likelihood function.

在生物医学统计中常接触到具有相关性的资料，这些相关性可能是基因、环境、重复测量或是时间所造成的；在这一类型的研究中，我们通常不只对治疗的效用有兴趣，观测值的变异以及观测值之间的相关性亦可能是我们所关注的量，这些变异或相关形式都可以被称为变异数成份。

The coefficient of component variance for high-frequency increased (p＜0.05) and low-frequency decreased (p＜0.01) in hypertensive patients with SAS after one night CPAP treatment.

活动后正常对照组和单纯高血压组Lc明显增加(p＜0.01，p＜0.01)，而SAS合并高血压组Lc却下降(p＜0.05)。一夜CPAP治疗后，SAS合并高血压组休息状态时Hc增加(p＜0.05)，Lc明显下降(p＜0.01)。

Thereby, these facts indicate that the SDE not only have better statistic properties but also have uniformly smaller mean square errors than ANOVAE in an available group of linear mixed models. The other significative following work is to generalize the idea of SDE to multivariate linear mixed model and obtain the SDE of variance component matrices which uniformly dominate the ANOVAE either.

对于含有一个随机效应的混合模型，目前文献中都仅讨论了方差分量的谱分解估计和ANOVA估计等价的充要条件，本文首次给出了方差分量的谱分解估计在均方误差意义下严格的优于ANOVA估计的理论结果，并推广到广义谱分解估计，从而说明谱分解估计不仅较ANOVA估计有更好的统计性质，而且在一类常用的模型下有更小的风险损失。

Like the numerator relationship matrix used in the traditional trait BLUP, in random QTL effect model of trait-marker BLUP, before estimating the variance component of QTL, the conditional relationship coefficient of additive QTL effects or the probabilities of being identical by descent of QTL alleles among relatives should to be known.

将QTL作为随机效应，和传统T-BLUP中分子血缘相关阵类似，在采用TM-BLUP进行种畜遗传评定，以及在进行QTL方差组分估计以前，首先要知道有亲缘关系个体QTL加性遗传效应间条件相关系数或基因同源相等的概率。

Based on the analysis of error characteristics and performance effect of the mostly used crystal oscillator, a method to simulate the frequency error of crystal oscillator is proposed. The major idea is to determine the Allan variance parameter of each main stochastic error component at the given sampling interval at first, then to deduct a set of corresponding frequency error series and superpose them together.

该文对在GPS接收机中使用最多的晶振的误差特性和性能影响进行了分析，在此基础上提出了一种模拟晶振频率误差的方法，即首先确定晶振在给定取样时间间隔上各主要随机误差成分的Allan方差参数，由此反演产生相应的各项晶振频率误差模拟序列并进行叠加。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
