变格的

The performance function and constraint equation in calculus of variations were constructed by analyzing input and output equations of the system containing parameters to be estimated. The traditional parameter estimation problem could be transformed to that of least squares estimation.

通过分析包含待估参数的系统输入输出方程，构造变分法中的性能范函和约束方程，将传统的参数估计问题化为带约束条件的最小二乘估计问题；利用拉格朗日乘子法，分析参数估计方程，得到参数的最优估计。

The soundness and completeness theorem of this method were proved at last. 5. The a-automated reasoning method based on the a-resolution principle of LP was discussed, the author given a method to describe the set of simple generalized clauses (veriables and non-subregular 1 - IBSFs are only contained) by using a matrix, and translated the a-resolution of two clauses to column operations of this matrix.

最后，证明了该方法的可靠性和完备性； 5、对格值命题逻辑系统LP中基于α-归结原理的α-自动推理方法进行了研究，给出了用符号矩阵表示一类简单的广义子句集合(只含命题变元和非正则1-IESF广义文字)的方法，把α-归结原理转换成矩阵的列变换。

" "Mathematics is ordinarily considered as producing precise and dependable results; but in the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative are the conclusions we draw there from … Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment.

格雷厄姆对数学在投资中的作用认为数学一般被认为是能產生精确和可信赖的结果。但是在股票市场，所用的数学越复杂深奥，其从中得出的结果也就越不确定，越具有投机性。一旦引入了微积分或者高等代数，你可以把这看作是一个警告，这意味著使用数学者是在用理论代替经验。通常这给了投机欺骗性的偽装，变得好像是投资一样。

The method that combines the effective - field renormalization group with the discretized path - integral representation is extenged to study phase transition of the transverse Ising model in a quantum - spin system on the plane triangular lattice.

将离散路径积分表示下的有效场重整化群技巧推广应用于平面三角晶格上量子自旋横向Ising模型的相变研究，在这个方法中，注意区分了两种具有相同配位数而不同几何构形的晶体，并且考虑了起伏的影响，在二阶累积量近似下，得到了接近于精确解的临界值。

All crystalline structrue has been investigated by XRD, on the basis of which the relationship between dopant dose and lattice constant and the size effect of phase transformation were discussed.

利用XRD研究了掺杂钛酸铅纳米晶的晶体结构，以此为基础讨论了掺杂量与晶格常数变化的关系以及相变的尺寸效应，并研究了掺杂纳米晶的相组成和晶胞参数。

Among the contemporary avant-garde writers in China, Ge Fei is famous for his unique narrative labyrinth. All the comments and appraises from the literatus witness the literature phenomena and the trend of thoughts of this period in contemporary China.

在当代的先锋小说作家中，格非以其独特的"迷宫式"叙事著称，文学界对他的评价和褒贬都见证了这一时期当代中国的文学现象和文学思潮的运变。

While he has seen a lot more action in Spain than in Italy, he has never had a very lengthy spell under Manuel Pellegrini, and the Villarreal coach's renewal at El Madrigal has helped him make his mind up.

然而当他希望在西班牙获得的机会多于意大利时，他却从来没有在曼努埃尔·佩莱格里尼那里获得很多的出场机会，主帅的变阵使得他重新审视在这里的一切。

Not only was he, in 1953, excommunicated from the International Psycho-Analytic Association but his provocative ideas disturbed many progressive thinkers, from critical Marxists to feminists. Although, in the Western academia, Lacan is usually perceived as one of the postmodernists or deconstructionists, he clearly sticks out from the space designated by these labels. All his life, he was outgrowing labels attached to his name: phenomenologist, Hegelian, Heideggerian, structuralist, poststructuralist; no wonder, since the most outstanding feature of his teaching is permanent self-questioning.

我们经常看见的拉康脸上的标签有后现代主义者、解构主义者等等，但他经常扯掉这些标签（很多学者喜欢在脸上多贴点呢，就好像斗地主运气不好时一样，这样一来即便被抓赌了，别人也不太容易看清楚自己的容貌），甚至连现象学家、黑格尔主义者、害得割耳主义者、结构主义者、后结构主义者这些大帽子也罩不住他；在给别人布道的过程中对自身的不断盘问使拉康学会了七七二十一变。

Firstly, this paper uses the method of renormalization group to deal with the Ising Model of equilibrium phase transition and calculate and compare the critical index of the model of square cell with different lattices, which leads to the finding that the size of Kadanoff cell have greater influence on the approximate treatment of interactions between cells.

本文首先用重正化群方法处理了平衡相变的Ising模型，计算了不同格点数的正方形元胞模型的临界指数并进行对比，发现Kadanoff 元胞的大小对元胞间相互作用的近似处理影响较大。

The peak has the typical phase transition character. Combined with analyses of XRD and DSC, it is proposed that the peak originates from the ordering process, which is caused by the jump of antisite atoms to their own sublattice sites through the nearest neighboring vacancies.

这个内耗峰具有典型的相变峰特征，XRD和DSC显示，该峰的出现与样品的有序化过程有关，它产生于反位置原子通过最近邻的空位向自身亚晶格位置的跳动。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
