查询词典 second boundary value problem

The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

利用GC—MS分析技术，在陆相地层中检测出正构烷烃、类异戊二烯烷烃、萜烷和甾烷类生物标志化合物并根据生物标志化合物和特征值研究，将二叠系—三叠系生物演化划分为三个大的阶段，即晚二叠世的菌藻类低等生物与高等植物混源阶段（63层以下），界线异常层的菌藻类低等生物阶段（63-69层）和早三叠世高等植物与菌藻类低等生物混源阶段（69层以上），界线附近异常层的第二阶段又进一步细分为4个次一级阶段，生物演化阶段与沉积环境变化及界线异常层具有非常密切关系。

Motivated by this, we consider the global behavior of positive solutions of three-point boundary-value problems for second-order differential equations, under two different kinds of boundary-value problems, using fixed point theorem, fixed point index theorem and cone theory.

本文受到文献[7]的启发，运用不动点定理、不动点指数定理以及锥理论，分别研究了两种不同边值条件下二阶微分方程三点边值问题正解的整体性。

FENG Kang, YU De-hao and some other scholars of our country are the first ones to create the natural boundary element method, and they have successfully studied the natural boundary reduction method for the boundary value problems of harmonic equation and biharmonic equation.

我国学者冯康、余德浩等首创自然边界元法，并已成功地研究了调和方程及双调和方程边值问题的自然边界归化方法。

In this paper the natural boundary reduction for some elliptic boundary value problems with concave angle domains and its natural boundary element methods are investigated.

本文研究凹角型区域椭圆边值问题的自然边界归化及其边界元法。

In order to bypass the difficulty of discretizing the boundary r or the Lebesgue discontinuous set Su in the Mumford-Shah model, we use an edge-detector function and a threshold value to induce a thin-belt where the image boundary lie in and displace the length of the boundary by the area of the thin-belt approximatively.

为避免在离散化Mumford-Shah模型中的边界Γ或Lebesgue不连续集S_u的困难，我们借助边界检测算子和门限值，确定图像边界所在的窄带区域，用窄带区域面积近似边界的长度。

It is proved by using the function approximation theory and martrix theory that for a degenerate elliptic equation of the first class, if the third boundary value condition is satisfied at its nondegenerate boundary and the given derivative values are satisfied at its degenerate boundary, then its solution is existent and unique.

摘 要 运用逼近理论及矩阵理论证明：如果一类退化椭圆型方程在非退化边界上满足第三边界条件，在退化边界上满足给定微商值，那么它的解是存在且唯一的。

The inventory consists of seven subscales: physiological value, psychological value, interpersonal value, affectional value, vocational value, moral value, and human life value.

量表内容包括有生理的价值、心理的价值、人际的价值、情感的价值、职业的价值、首选的价值及人生的价值等七个分量表。

The paper draws the following conclusions:Brand value is the evaluation to the brand as asset and equity and it can be expressed as brand financial value and brand equity. Brand value comes from the extra utility it takes to the customers by satisfying their special needs. The forming base of the brand value is closely relative to the customers, and there are some other factors infecting brand value such as brand extension. Brand value evaluation includes two parts. One is to have a valuation to the brand financial value, the other is to evaluation of the brand equity by choosing a suitable brand equity model.

经过上述研究，本文得到以下结论：品牌价值是对品牌作为一种资产和一种权益的价值量化，具体体现为品牌财务价值和品牌权益价值；从效用价值论的角度，品牌价值来源于品牌带给消费者的特殊效用；品牌与消费者的关系是品牌价值的形成基础，品牌价值的大小还要受到其他因素的影响；完整的品牌价值测评应由两方面构成：按照收益法原则测评品牌的财务价值；选择适当的品牌权益模型对品牌权益进行测评。

This paper doesn't research on the general theory and method for valuation, while I try to find a unique way to improve and apply the traditional valuation theory and method in order to meet the need of the new background and new environment. Putting valuation into the value chain background, research on corporate valuation of node corporations of value chain and the value distribution in a value chain, through which the valuation result will reflect the value aim of those companies in value chain and establish a basis for companies to make sure their strategic positions in value chain and to plan their strategy are the main creations of this paper.

因此本文并不是研究价值评估的一般理论与方法，而是将价值评估置于价值链理念下，研究价值链结点企业的价值是否达到了预定目标，并试图建立整条价值链的价值库，以掌握价值链的价值分布问题，从而帮助企业分析自己在价值链中的战略位置，为企业进行战略目标的制定打下良好的基础。

After that, the article expounds how the social labor value theory overcomes the theoretical hard nuts in the financial accountings:(1) it has solved the issue of conformity between the production domain and accounting domain by holding that the social labor creates the value, which decides that the domains of production and accounting should be extended to cover the tertiary industry;(2) it has solved the issue of the valuation standards in the economic accounting by holding that the theoretical value should be converted into the actual value and that only when the price of production is used as the valuation standards can the financial accounting and economic accounting have a true valuation basis;(3) it has solved the issue of creation and distribution of surplus value and explicitly points out that the power of science and technology determines that the surplus value comes mainly from the materialized labor. Only when we have a clear understanding of this point and have realized that the value of product is created jointly by the materialized labor and the laborer can we straighten out the relationship in the distribution of earning inside the enterprise and understand that the distribution on the basis of contributed capital is a reasonable choice at present.

其次，着重阐述了社会劳动价值论如何解决经济核算中的理论难题：一是解决了生产范围与核算范围的统一问题，认为社会劳动创造价值，决定了生产范围与核算范围都必须扩大到第三产业；二是解决了经济核算的计价标准问题，认为必须从理论价值转化为实际价值，用生产价格作为计价标准，才能使会计核算和经济核算真正具有计价基础；三是解决了剩余价值的创造与分配问题，并明确指出，科技的力量决定了剩余价值主要来自于物化劳动，只有认清这点，承认企业的产品价值是物、活劳动共同创造的，才能真正理顺企业的利益分配关系，才能理解按资分配是现实合理的选择。
