First of all, we introduce some interval methods and propose a new approach to find confidence interval for the slope in homoscedastic measurement error models. The performance of the interval estimation is compared in terms of both coverage probability and its diameter via simulation studies. Second, we suggest two approaches to estimate confidence intervals for the slope and joint confidence regions for both intercept and slope in heteroscedastic measurement error models. Application of these methods are illustrated with real data sets.

首先，当测量误差的变异是同质性时，我们对斜率项参数建构信赖区间，除了回顾已发表的方法外，也提出一个新的方法，建议的区间方法分别和已存在的方法做模拟比较，比较的标准建构在覆盖机率和平均长度上；另外，当测量误差的变异是异质性时，我们不仅对斜率项参数建构信赖区间提出新的方法，也对截距项参数和斜率项参数建构联合信赖区间。

In this paper, three methods for color image retrieval have been presented: hypercomplex SVD image retrieval, combination of hypercomplex convolution filter and hypercomplex SVD image retrieval and hypercomplex matrix correlation image retrieval. We made comparison among these hypercomplex-methods, and compared them with the traditional image retrieval methods. Experiment results showed that the hypercomplex-methods we presented in this paper could well conquer the problems existed in traditional image retrieval methods, and their retrieval results are much better. Meanwhile, this paper presented a new color image quality assessment based on hypercomplex SVD. It is a novel color image quality assessment that can be used as a graphical or a scalar measure to predict the distortion introduced by a wide range of noise sources. It reliably measures the distortion not only within a distortion type at different distortion levels, but also across different distortion types.

提出了超复数奇异值分解检索法，超复数卷积滤波与超复数奇异值分解相结合的检索法以及超复数矩阵相关检索法等三种超复数彩色图像检索方法，在对提出的三种算法进行比较的同时也将其与传统图像检索方法进行了比较，结果证明，超复数彩色图像检索法能较好地克服传统图像检索方法存在的问题，且检索结果更优；同时，本文提出了基于超复数奇异值分解的彩色图像质量客观评估法，这种全新的图形化与数值化相结合的方法不仅能够准确评估出彩色图像的不同失真等级，还能够区分不同的失真类型，从真正意义上实现了彩色图像的质量评估。

This article compared the integrand of infinite integral and unbounded function integral by comparing the infinitesimal with the infinity, obtained the corresponding equivalence theorem of criterion of convergence of abnormal integral, and gave out the proof.

将无穷积分及无界函数积分的被积函数运用无穷小和无穷大比较的方法进行比较，得到了相应的反常积分敛散性极限审敛法的等价定理，并给予证明，从而可运用等价定理灵活的判断反常积分的敛散性。

However,since these patients discharged from hospital for two weeks,the treatment compliance of these patients had began declining.Through the result we also find out that the treatment compliance would be declined if patients discontinued participating education for a long time.4.The result of self paired comparison suggests that diabetes education can influence QOL of diabetics.

Using the DG index to measure the diversity of soil invertebrate assemblages was more reasonable than Shannon-Wiener Diversity Index in this case because the Acarina predominated in the samples which covered up the information of other soil invertebrate taxa, while the DG index is proposed on base of the hypothesis that every species has equal independence and importance in the community and could be compared with inter-community.

在本研究中，应用密度类群指数分析土壤无脊椎动物多样性的结果比应用Shannon-Wiener多样性指数的结果更为理想，这是因为土壤无脊椎动物由于组成结构复杂，不同类群的个体数量往往存在着巨大的差异，例如蜱螨目的较大数量常掩盖了其它类群的重要信息，多样性指数不能体现这一情况，而密度类群指数是基于各物种在群落中都有同等独立性，宜在不同群落间进行同种类比较的假设，对于复杂的土壤节肢动物群落多样性的测定可获得比较贴切的结果。

There are no distinct differences between ancestral character state and descendant character state in some characters. 4. Only one outgroup can't give enough information to tell what the ancestor looks like. It make us not to understand how a lot of charactors evolved. 5. The matsutake group is polyphyletic. 6. The character coding is not precise enough. 7. Some characters are not homology. The result of molecular systematic study on the matstuake group shows the group is not monophyletic. The matsutake group is more closed to Tricholoma than Armillaria. ITS sequence of Catathelasma ventricosum is nearly identical to that of the matsutake group, although apparently they are very different from each other in morphological characters.

对松口蘑群通过形态学特征进行系统发育关系分析造成很大的干扰的原因有：松口蘑的种类大多形态特征比较简单，可提供进行分析的特征不多；某些性状在一些状态之间的反复转化，造成分析上的误差；在进化过程中某些性状无明显的祖征和衍征，在分析过程中很难确定进化极性；选择外群时应该用一个特定类群进行整体理解后，确定各个性状的极性，不要只用单种作为外群；松口蘑群是一个多系群；进行比较的性状不一定是同源的；数量性状编码过于粗放，反映不出真实的情况。

In a word, by the research method of comparison and emphasis on the bud, form, development and contabescence of feudal lord system from Song dynasty until the initial stages of liberation, this dissertation discusses the intrinsic factors of the social form of feudal lord system by comparing the similar nationalities, Dai Nationality of Xishuangbanna inYunnan and Zhuang Nationality in western Guangxi, hoping to realize the common disciplinarians of the two nationalities and find the special process of them.

总之，全文通过论述桂西壮族和西双版纳傣族宋代至解放初期封建领主制萌芽、形成、发展、衰亡的发展历程，通过比较的研究方法，比较桂西壮族和西双版纳傣族两个相近似的民族地区在封建领主制这一社会形态中的异同和形成这种异同的内在因素，冀此来认识两个民族社会发展进程中所经历的共同规律，发现这两个民族各自经历的特殊历程。

What I am remarking focuses on those more "solemn" or inspiring and useful programs, which can not just randomly let someone to preside, but should have the participation of experts, at least someone that is a professional in certain trade (even if he did not belong to the mcee profession ).

我所主要讨论的是那些比较&庄重&或者说对人有启迪、帮助的节目，不能随便的拉个主持人来主持，而应该有专家的参与，最起码是对某一行比较的专业（即便他不属于主持的行业）。

It is not clear, however, to what extent these mechanisms might overlap because there is some evidence that the local stimulus of more frequent milking can, in turn, cause more nutrients to be delivered to the udder at the expense of other tissues (DePeters et al., 1985; Kazmer et al., 1986), although there is no evidence of major repartitioning comparable to that seen with growth hormone injections.

Bauman 和弗农，1993它不清楚，然而，到什么范围因为有比较时常发生挤奶的当地刺激能，依次的一些证据，所以这些机制可能重叠，引起要递送到乳房的较多的营养物牺牲其他的薄纱织品(DePeters 及其研究同仁，1985； Kazmer 及其研究同仁，1986)，虽然没有对于主修科目的证据再分配可比较的对那与生长荷尔蒙注入一起见到。
