It is interesting that (1)hyperconjugation of the solvent's CF3-donor group prefers H4/H5 of BMI cation to H2, which can be explained by the steric hindrance of PF6 anion;(2) the various-temperature 19F spin-lattice relaxation times (T1) of CF3 show phase change, e.g.

藉由分析阳离子和三氟乙醇的扩散速率求得DD值，可以看到改善在乙醇形成大的基团，产生较强的分解，三氟乙醇的性质利用19F、1H化学位移，得到(1)CF3和阳离子H4、H5形成超共轭大於对H2，因为立体效应的关系，而藉由19F迟缓时间的数据，三氟乙醇展现相变化，由一到两各堆叠的离子对，和一个阴离子形成超阴离子的情形，因为溶剂而开始崩解，在继续分解可得到自由的阴阳离子。

Based on the elliptic curve cryptosystem, a multi-key sharing scheme in which the Lagrange interpolation polynomial is used and the cheaters can be detected is presented.

文章利用拉格朗日插值的思想，提出了一种基于椭圆曲线的可防欺诈的动态多密钥共享方案；方案中每个参与者的子密钥可以不受限制的重复使用，因此在更新主密钥的时候，无需更改参与者的子密钥，从而减少了可信中心与参与者之间的通信量；方案可灵活地增删参与者，且安全性是基于椭圆曲线离散对数问题的难解性，因而其安全性比在有限域上更高；方案实现过程中解决了检验子密钥真伪的问题。

In this algorithm, the solving space of logical variables is reduced by logical constraints, and the computational complexity is not raised exponentially when the logical variable number is raised. The scale of the NLP sub-problems is also reduced. The global optimal solution will be obtained, and the local optimal problem of nonlinear system is avoided.

算法的特点为：利用逻辑变量的物理意义来缩小求解空间，避免了计算量随逻辑变量数目呈指数型上升的问题；NLP子问题的规模大大缩小，加快了求解速度；可以得到严格的全局最优解，避免了非线性模型可能带来的局部极值问题。

The abstract result contains several concrete results in the literature and can also be used to deal with some new cases for resonant differential equations.In the introduction, we briefly introduce the development process of the variational methods. In Chapter 2, we list some basic knowledges refering to the variational methods, including the Sobobev space,—△ operator, the weak solution and the minimizing sequence methods and some minimax theorems. In Chapter 3, we introduce the research process of Hamiltonian system of second order and the semilinear elliptic problems, using the methods introduced previously. In Chapter 4, we prove the main theorem of the thesis, and apply it to the problems in the previous Chapter, and can also be applied to some new resonant cases.

How to choose strategies of handing traditional culture down is an unavoidable subject in the new situation. The author of the article thinks that clothing, which is believed to be the visiting card of a people, should be simple with symbolization, pictorialization, totems and commercialization. Handing down of the living culture should be combined with ecosystem environments and places of interest to develop its content step by step. One cultural item should be exploited in one place to keep it alive forever. We should make good use of educational, research and translating organizations, media and the Internet to propagandize old and new characters and works. Some museums should be built up to protect metallic and stone relics. Setting up ecological museums or cultural villages and parks is an effective method. We should find out a new way in which key points about the understanding of the culture are explained clearly, core advantages are developed and cutlural labour force and propaganda work are revived The most important thing is to make complete use of the laws and policies on minority self-rule to find out the best way to keep Yi's traditional culture alive.

作者认为，作为民族身份"名片"的服饰应以简明为原则尽量符号化、图案化、图腾化、商业化；作为活文化的仪式与习俗的传承，除了在经济发展的前提下以村寨为基本单位尽量保护和弘扬，要尽可能与生态环境和旅游胜地紧密结合进行单个文化主题的念珠式贯串开发，一地深入开掘一个文化内蕴，使之可以传之久远；依托教育、科研、翻译机构和文艺传媒、互联网传承新老文字及典籍文化，建立文博场馆保护金石文物；建立民族生态博物馆或民族文化村文化园等也不失为一种有效的方式；译解文化传承基因，培育核心发展优势，形成文化再生力传播力，是一条应该认真探索的道路；最重要的是要充分利用好民族区域自治政策法规，使之发挥的效益最大化，并从法律和政策上寻求最佳的传统文化传承策略。

The multicast routing problem that finding the minimum cost multicast routing tree with many QoS constraints may be formalized to Steiner tree problem in network, which is a NP-complete problem that an algorithm that finds a Steiner tree can not get the best solution in polynomial time.

寻找有多个QoS约束的最小代价组播路由树可以形式化为网络中的Steiner树问题，它是一个NP完全问题，在多项式时间内不能得到最优解，因此研究者所寻求的是一种次优的、在最差情况和平均情况下的性能都接近于最优的解决方案。

Considering the coupling connections among the functional cells and their complicated relationships,such as connection in series, in parallel and in both of them and so on, as well as among the sub-structures, a computerized conceptual design method is given out for mechanical systems based on the function decomposition and recomposition method.

Against England, the most important of all the Protestant nations to reconquer, military might was not yet possible because the Catholic Powers were too occupied and divided: and so, in the 1570's Rome bent her efforts, as she had done a thousand years before in the days of Saint Augustine, to win England back by means of her missionaries the most important of all the Protestant nations to reconquer,这句话是同位语,说明 England.

对付英国，需要重新征服的所有基督教国家中最重要的一国，动用军事力量不可能。因为天主教大国们太忙，太分裂；因此罗马于 1570 年代就像一千年前，在圣奥古斯都统治时期它曾做过的那样，竭尽权力想通过传教方式把英国赢回来。写作方法与文章大意这篇文章论及"罗马教皇采用文武两手政策在欧洲，特别在英国，恢复旧教——天主教。"采用一般到具体的写作手法。可以说由大到小。大的欧洲背景，最后落实在英国的具体做法。重点在英国。答案祥解 1。
