上理想

The ideal simple pendulum movement is not practical though it is simple,and the practical case comes from the correction and improvement of the ideal case.

理想的单摆运动虽然简单却不实际，实际情况需要在理想情况的基础上进行修正和改进。

Conversely, in terms of the correspondence between the pure state and the maximal left idea, we get that if each hereditary C(superscript *)-subalgebra (or one-sided closed ideal) of A is a closed ideal in A, then A must be Abelian.

反之，利用C-代数A上的纯态与A中极大左理想的对应关系，得到了：若A中的每一个遗传子代数都是它的双侧闭理想，则A一定是交换的。

In section 2,we characterize the minimal ideals of finite dimensional symmetricself-dual Lie algebras over the complex field and gives an optimistic lower bound for thedimension of the space of invariant symmetric bilinear forms on a symmetric self-dualLie algebra by means of the number of linearly independent minimal ideals.

在第二节中，我们完全刻划了有限维对称自对偶李代数的极小理想；用线性无关极小理想的个数给出了一个对称自对偶李代数上由不变对称双线性型构成的线性空间维数的最好下界

By means of the fractions of the equation of the non一ideal constrained motion of the particle along the plane curve on the tangential direction and normal direction,the motion speed expression of the particle under this condition is derived,the constrained counter force is further gained,thus some non一ideal constraint problems are solved from the given angle.

通过质点沿平面曲线的非理想约束运动方程在切线和法线方向上的分式，导出质点这一条件下的运动速度表示式，并进一步求出其约束反力，从一定角度解决一些非理想约束问

It is good to theorize, that is to say, to analyze the problems confronting us a nation and elaborate an ideal solution for each of them.

把我们作为一个民族所面临的问题提到理论上加以分析，并为每个问题制定一个理想的方案并为每个问题制定一个理想的方案，这是对的。

In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained. By analyzing the reasons leading to overheating and unideal heat distribution, corresponding thermal simulation using an improved model was carried out. Finally, the comparison and analysis of experimental measurement results and simulation results were given.

本文基于计算流体力学中的有限体积法，建立了该变换器的热仿真模型，利用EFD Pro 8.2软件，对驱动电源内部进行了热场及热应力分析，得到了各部分的温升情况和整个电源温度场的分布情况，分析导致PCB局部过热的原因，然后针对热仿真得出的不理想的热分布情况提出了改进的方法，进行了模型改进，对PCB板上的各部分进行合理的重新布局，并再次进行了热仿真，最终得到了较为理想的结果，最后给出了实验测量结果与仿真结果的对比及分析。

According to the analysis of problems in the traditional TOPSIS, entropy and vertical projection are used to improve the TOPSIS method, which can avoid not only the non-determinacy and optional judgments resulted from subjective opinions, but also the problem that coinstantaneous scheme may be ideal or not, so that it can improve its scientificity and rationality.

在分析传统的TOPSIS法存在的问题基础上，提出采用熵权法和正交投影的思想改进TOPSIS法；改进的模型既可避免优选结果受主观判断的不确定性和随意性，又可避免距理想解近的方案与负理想解也近的问题，提高了TOPSIS法的科学性和合理性，且模型计算相对简单。

In the respect of life ideal and aesthetic pursuit, Zong Baihua takes Goethe as his exemplar. His ideal of " artistic life" contains not only classic humanist standpoint, but also the moulage of Kantist super-utilitanrianism. On one hand, his ideal is full of moving creative spirit of Goethean lasting pursuit of life.

在人生理想及其美学追求上，宗白华以歌德为模范，其&人生艺术化&理想既包含着古典人道主义的立场，又有康德式超功利观念的印痕；既洋溢着歌德式生命永恒追求的运动创造精神，又体合了叔本华所意欲的以审美静观、艺术为人生解脱的超世方式。

FEMOL is systematically applied to various moving boundary problems, including: membranes contact with rigid foundation, shape optimization of cross-sections of elastic torsional bar, seepage through a dam with a free surface, Mindlin-Reissner plates contact with rigid foundation, free Mindlin-Reissner plates on tensionless

三、将有限元线法分析推广应用到了一系列的动边界问题中，包括：薄膜接触问题，弹性扭转杆的截面优化问题，自由液面的稳定渗流问题，中厚板理论与刚性地基的接触问题，无拉力Winkler地基上自由中厚板问题，理想弹塑性扭转问题，理想弹塑性Ⅲ型裂纹问题。

We then add boundaries delineated forward/backward facing reflected shock, Mechanical equilibrium, M2=1 and reflected shock strong/weak separating conditions on the (M0,q1) map of shih(2004). This is followed by systematically investigating multiply possible three shock theoretical solutions of steady Mach reflections in perfect triatomic gases. Pressure-deflection shock polar solutions are used to help illustrate different solution behaviors of these theoretical three-shock solutions. M0 is flow Mach no. upstream of incident shock, M1 is flow Mach no. downstream of incident shock, M2 is flow Mach no. downstream of reflected shock,q1 is flow deflection downstream of incident shock.

随后本文由石(2004)论文中加入前后分界、机械平衡、M2=1及强弱分界条件，然后有系统地探讨三原子分子理想气体(r=1.2857 )稳态马赫反射参震波理论多重解之交点及其对应之压力-转折角震波极图解，并建构出此三原子分子理想气体稳态马赫反射流场三震波十阶多项式理论解於(Mo，q1)平面上之解域图，其中M0为入射震波上游流场马赫数，M1为入射震波下游流场马赫数，M2为入射震波下游流场马赫数，q1为入射震波下游流场转折角。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
