查询词典 condition equation

However, methods and references for difference equation are relatively less. The new method proposed in this paper transfer the complex boundary value problem into the existence and uniqueness of the solution of the linear equations. For linear case , we obtained the necessary and sufficient conditions for the existence and uniqueness of the solution for the BVP; For the nonlinear case ,we got a series of new sufficient conditions by using contraction mapping theory and cone theory .

而差分方程边值问题的研究方法和文献还很少，文中新的研究差分方程边值问题的方法是将复杂的边值问题求解转化为代数理论中的线性方程组解的存在和存在唯一问题；对线性情形，较容易地获得了边值问题的解存在以及唯一的充分必要条件，而对非线性情形，则通过压缩原理和锥理论等各种不动点定理，获得了一系列新的充分条件。

Using integral equation theory and"contraction mapping"theorem, we prove that this model has a unique solution.

接着用压缩映象原理证明了此模型解的存在唯一性，这为讨论经济系统的稳定性奠定了数学基础，又通过对定常的投资方程渐近稳定性的研究和非定常投资方程Liapunov稳定性研究，我们分别讨论了积累率、劳动力和科技进步对经济增长的作用，进而指出只有依靠科技进步才能实现经济的持续增长，才能真正提高人民的生活水平。

Secondly, we give a concise proof of the backward equation for Markov skeleton process .

第二，给出马尔可夫骨架过程的向后向前方程的一个十分简洁的证明。

It is shown that the parameter K in Greenwood-Johnson equation is relative to martensite.

4通过实验，得到的相变塑性公式中常数K和马氏体转变量有关。

The model is simple because only one dynamic equation of martensite is adopted.

计算结果表明，本模型预测的应力应变曲线与实验结果吻合。

High accurate degree and good stability are shown in the self memory equation by mass numerical results.

大量数值结果已表明自记忆方程具有很高的精度和很好的稳定性。

Finally, the physical nature of the Einstein\\\s mass-energy equation is discussed. It is emphasized that the elativistic increase of the mass of a moving body is physically untrue.

我们探讨了爱因斯坦质能方程所蕴含的本质物理内涵，强调运动不可能导致运动物体质量的增加。

In addition, there is a new cognition on inertial mass, Newton's second law, kinetic energy, mass-energy equation and momentum in the paper.

我们对惯性质量、牛顿第二定律、动能方程、质能方程、动量等重新进行了深刻地认识。

Basing on this, this article deeply analyzes the relations between implication and the connective "If, then" used in ordinary logical thinking, and points out that material implication is scientific abstract generation to the ordinary language "If, then". Their sameness lies in: when a conditionals protasis is true and its consequent is false, material implication equation is false.

在此基础上，论文深入地分析了蕴涵与人们极易混淆的日常逻辑思维中的"如果，则"的关系，指出实质蕴涵作为数理逻辑中对日常语言"如果，则"的科学抽象地概括，二者的相同点在于：当前件真后件假时，充分条件假言判断为假，实质蕴涵式也为假。

Summary In copyright infringement cases,if the alleged infringer uses or even plagiarizes the copyrighted works or parts thereof,which causes no substantially adverse effect on the normal exploitation of the work,nor does it inflict any substantial damages to the right owner,the de minis doctrine should be applied to exempt the liabilities of the defendant and seek the balance of interests between the right owner and the general public embodied by the copyright law.

在侵犯著作权案件中，如果被控侵权行为人虽未经著作权人的同意，使用甚至抄袭了受著作权保护的作品或作品的片段，但若情节轻微，未对该作品的正常使用产生任何实质不利的影响，亦未对权利人的权利造成实质性的损害，则应适用&不计琐细原则&，免除行为人的责任，以寻求在权利人利益与著作权法所体现的社会公共利益之间的平衡。
