Generalized Linear Models are an extension of the linear modeling process that allows models to be fit to data that follow probability distributions other than the Normal distribution, such as the Poisson, Binomial, Multinomial, and etc.. Generalized Linear Models also relax the requirement of equality or constancy of variances that is required for hypothesis tests in traditional linear models. Hypothesis tests applied to the Generalized Linear Model do not require normality of the response variable, nor do they require homogeneity of variances.

广义线性模型是线性模型的扩展，对数据的要求不必局限于服从正态分布，同时放松了对"方差一致性"的要求，这在传统的一般线性模型假设检验中是必不可少的，而在广义线性模型假设检验中，响应变量也可以服从其它分布（如：泊松分布，二项分布及多项分布等）。

However, historians have traditionally disagreed as to whether the skin Hercules is portrayed wearing in such works of art is that of the Nemean Lion or that of different lion entirely……one which Hercules is said to have killed when he was eighteen years old.

希拉当然不会因为一次失败就放弃杀死赫五力，她故意让赫五力发疯候打自己的妻子，赫五力醒了以后十分懊悔伤心，决定要以苦行来洗清自己的罪孽，他来到麦西尼请求国王派给他任务，谁知道国王受希拉的指使，果然赐给他十二项难如登天的任务，必须在十二天内完成，其中之一是要杀死一头食人狮。

We find that the orthorhombic distortion leads to a secondorder coupling term between the d-and s-wave order parameters,which results ina nonvanishing s-wave component even in a uniform system and a mixed d+s-wave pairing state.

正交畸变使得GL自由能密度泛函中包含了d波与s波序参量的二阶耦合项。这一项的存在使得即使在空间均匀的情况下也会有非零的s波成分存在，并且导致d+s混合波配对态。

The spatial distribution of intra-node flux and source were approximated by a new orthogonal quadratic polynomial expansion, and a second-order polynomial provided the spatial expansion of transverse-leakage. The neutron angular distribution of flux and transverse-leakage were represented by the S quadrature set.

Hierarchical linear modeling is the most frequently used technique for analyzing multilevel data. In this paper, the twelve key issues in multilevel research and/or using HLM software were reviewed, and provided their exact meanings and feasible solutions. The 12 key issues included intraclass correlation coefficient, sample sizes, formation of organizational constructs, centering problems, fixed effect and random effect, estimation methods, goodness of fit index, explained variation, multicollinearity, robust standard error, level one variance equation, and empirical Bayes estimates.

ResultsThe similarity, digit span, digit sign, picture, picture remembrance , vision renew in patients after treatment were higher than those before treatment ( P .05). As to the total number, total error number and persistent error number of WCST (P . 05).DiscussionIn this study, thirty - five patients who took Risperdal treatment have cognitive function disorder in different disagree, after 12 weeks, nine items among twelve items reflecting cognitive function have significant difference , indicate cognitive deficits in schizophrenia are reversible and related to new type antipsychotic drug .

实验结果 35例患者在服用利培酮治疗前和治疗12周后认知功能的测验的比较，在相似性、数字广度、数字符号、填图、图片回忆、视觉再生测验中有显著性差异（P＜O.05L在＊qT中，总测验数、总错误数、持续错误数均有显著性差异沙＜o.05人讨论本研究中35例病人应用利培酮治疗前均有程度不同的认知功能损害，经12周治疗后，反映认知功能的十二项分测验中的九项均与治疗前呈显著性差异，提示精神分裂症的认知功能损害具有可逆性，且与新型抗精神病药物密切相关。

First, It estimates the frequency-modulated coefficients by performing Radon transform to the ambiguity function result of the LFMs.

首先，通过对信号模糊函数进行Radon变换获得各分量的调频系数。然后用滤除单分量自项二次项的方法使信号成为普通的正弦信号。

Moreover, it indicates that the error is reduced with the increase of the exponent number of the Asymptotic Boundary Conditions. In the third chapter, based on the Laplace equation, the limitation of the variation methods are deduced from the process proving the operator to be self-adjoint and positive definite.
