查询词典 boundary value problem

This paper criticizes 4 specious propositions about current controversy on theory of value:（1）the proposition that labor is the only resource of value needn't to be verified;(2) value is created by live labor, but distributed by ownerships of production factors;(3) value is determined in the process of production, but realized in the circulation;(4) value is a kind of social relationship, where there is no atom of use-value.

论文提要本文剖析了当前有关价值争论中的4个似是而非的命题：（1）劳动是价值的惟一源泉无需证明；（2）价值是由活劳动创造的，价值的分配是按生产要素所有权进行的；（3）价值是在生产过程中决定的，在流通中实现的；（4）价值是一种社会关系，其中不包含任何使用价值原子。

The result showed that,if only the necessary but insufficient condition,the equilibrium condition ,was adopted to deal with the infinite uncertain boundary condition,the solution to the stress was non-unique due to the fact that the boundary problem here was a mal posed mathematic problem.

通过两个典型的半无限体实例，对水平表面作用无限均布压力下弹性地基的应力和位移解答进行研究，结果表明：对边界条件不明确的无限边界仅采用解答的必要非充分条件——平衡条件来等效处理，其应力解答不是唯一的，因为此时该边值问题不是一个适定的数学问题。

Westerner emphasize ethics value with ontology, epistemology relative meaning, it's the congenital defect of" value question" when western traditional philosophy thinking; Though among China traditional philosophies, originated places to embody, but, going with enervation trend of traditional culture and the impacts of western culture, especially, affected by Russian textbook of Marxism, we do not only realize the value natural instinct of China"s traditional philosophy as consciously, and philosophy is studied and comes from the west to think" value question" instead, even in order to coming and study people"s" value problem" western traditional the thinking frames. This is what cause contemporary people and historical origin of the double predicament of philosophy, also is the realism meaning of the animadvert on the present philosophy view.

西方人在与本体论、认识论相对的意义上强调伦理价值，这是西方传统哲学思考"价值问题"的先天性缺陷；虽然在中国传统哲学中，起始处就是体现为以"内求诸己"的方式把握人"生命之道"的价值性的思想，但由于近代以来伴随传统文化的衰弱趋势和西方文化的冲击，使我们一味效仿西方哲学的范式去研究哲学，尤其是受前苏联马克思主义教科书体系的影响，我们非但没有自觉意识到中国传统哲学的"价值问题"指向，反而认为对"价值问题"的哲学研究源于西方，甚至在被马克思终结了的西方传统形而上学的思维框架中来研究人的"价值问题"，这是造成当代人与哲学双重生存困境的历史根源，亦是当代哲学观批判的现实意义。

With the discussion of extreme value problem of the multiple-valued function,and the popularizing of extreme value theory of the two-value function,This paper obtains differentiation rule about the extreme value of the multiple-value function,and illustrates the apllication of the theory with the example,providing proper guidance for the teaching of calculus.
