For the Riemann boundary value problems for the first order elliptic systems , we translates them to equivalent singular integral equations and proves the existence of the solution to the discussed problems under some assumptions by means of generalized analytic function theory , singular integral equation theory , contract principle or generaliezed contract principle ; For the Riemann-Hilbert boundary value problems for the first order elliptic systems , we proves the problems solvable under some assumptions by means of generalized analytic function theory , Cauchy integral formula , function theoretic approaches and fixed point theorem ; the boundary element method for the Riemann-Hilbert boundary value problems for the generalized analytic function , we obtains the boundary integral equations by means of the generalized Cauchy integral formula of the generalized analytic function , introducing Cauchy principal value integration , dispersing the boundary of the area , and we obtains the solution to the problems using the boundary conditions .

对于一阶椭圆型方程组的Riemann边值问题，是通过把它们转化为与原问题等价的奇异积分方程，利用广义解析函数理论、奇异积分方程理论、压缩原理或广义压缩原理，证明在某些假设条件下所讨论问题的解的存在性；对于一阶椭圆型方程组的Riemann-Hilbert边值问题，利用广义解析函数理论、Cauchy积分公式、函数论方法和不动点原理，证明在某些假设条件下所讨论问题的可解性；广义解析函数的Riemann-Hilbert边值问题的边界元方法是利用广义解析函数的广义Cauchy积分公式，引入Cauchy主值积分，通过对区域边界的离散化，得到边界积分方程，再利用边界条件得到问题的解。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.

如同这个，不仅拒绝放射性和等时线地球年代测定方法，争论基于可争论的假定，而且采用这类冰核和树木年代学测定，树木年代学使得均变论假定一览无遗和暗示了地球比Ussher-Lightfoot日历更为古老。

However, in some situations, models are hard to satisfy these assumptions at the same time. We meet a number of random errors with serial correlation and heteroscedasticity in practical problems. The rationality of these assumptions for random errors is doubtable. Therefore, it is necessary to test for correlation and heteroscedasticity in regression, which is an important step of dealing with regression problems and plays an important role in theory and practice.

但实际问题中，回归模型很难同时满足Gauss-Markov的三个假设，人们在实际问题中发现许多随机误差出现序列相关和方差不同的现象，因此对回归模型的随机误差的独立性和方差齐性的假设产生了质疑，从而展开了回归模型的相关性和异方差检验的研究，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。

As a result, the input symbols are no longer identically and independently distributed by definition and the distribution of PAPR derived for contiguous OFDM signal under these assumptions is not valid for the PAPR of NC-OFDM signal under these assumptions is not valid for the PAPR of NC-OFDM signals.

结果，输入符号不再是相同的，独立分布的定义和分配PAPR的推导毗连OFDM信号根据这些假设是无效的PAPR的数控OFDM信号根据这些假设是无效的PAPR的数控- OFDM信号。

His strategy is to argue for an explanatory gap on more cautious assumptions -- assumptions that are compatible with the truth of physicalism.

他的策略是认为解释鸿沟依赖于更为隐秘的预设：这些预设是相容于物理真的。

So, the assumptions for the entrepreneur"s human nature, basic needs, desires as well as common behavior intention and aims as well as the ideal assumptions of economic ""ought to be" and morality "is" which the entrepreneur achieved andexpected, and become a fundamental prefabricate premise of designing the mechanisms of incentive and moral restriction of the entrepreneurs behaviors.

因此，对企业家的人性假设，对其基本需要、欲望以及一般行为动机和目的的假设，以及企业家所达到的经济实然和所期待的道德应然的理想假设，便成为设计企业家行为激励和道德约束机制的基本预制性前提。

Its aim is not to teach specific skills but to sensitize employees to the assumptions they make about others and how these assumptions affect their behaviors, decisions, and judgment.

它的目的不是教给员工具体的技能，而是使员工认识到他们的假设对其他人的影响和这些假设怎样有效他们自己的行为、决定和判断。

this paper discussed several untestable assumptions which were often used in epidemiologi-cal observational studies,and some paradoxical results that may arise under different assumptions were showed.simpson's paradox and lord's paradox were introduced.assumption of treatment assignment in causal inference of epidemiological studies,assumption of control group in evaluation of exposure ef-fects,and assumption of missing data mechanisms in incomplete data analysis were also discussed.

本文主要讨论流行病学观察性研究中几种常用的假定，介绍simpson's悖论和lord's悖论，逆回归问题，以及在不同假定下可能出现的相互矛盾的结果。探讨流行病学研究的因果推断中处理分配机制的假定，暴露作用评价中对照组的模型假定，以及不完全数据分析中缺失数据机制的假定。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
