The study of lattice-valued propositional logic system based on lattice implication algebra.On the bases of previous study, by using the concepts and methods of T algebras we established the lattice-valued propositional logic system LP , whose truth values domain is a lattice implication algebra, and discussed systematically the semantical and syntactical properties of LP , proved the soundness theorem 、consistency theorem、deduction theorem and the decidability of validity of the system when the truth values lattice is finite. We also discussed the relationship between the α-theorem of some premise, say A, and the closed sets that contain A.

本文在前人研究工作的基础上，利用T代数的概念与方法，建立了真值取于格蕴涵代数的格值命题逻辑系统LP，对它的语义及语法性质进行了较系统的研究，得到了它的可靠性定理、协调性定理及演绎定理等，证明了值格有限时系统"有效性"的可判定性并讨论了某一前提A下的α定理与包含A的闭集之间的关系。

Based on a lot of empirical analysis, the author summerizes that the historical premises of mergers in the United States include of the development of modern-enterprise、the technical innovation、the expansile demand and the development of capital market, surveys the developments and characters of mergers in the United States. From Marx's capital concentration theory to the arguments between structure school and conduct school, from the theories of economists at the present age abroad to the achievements of the learned men in China. the author surveys the theorical developments of merger. Making a clear definition of the concept and premises of self-organizational merger on the hypothesis that enterprise is a kind of self-organization, futhermore, the author constructs the theoretical frame of self-organizational merger.

主要内容有：在对大量实证材料分析的基础上，归纳出美国企业兼并的历史前提是现代企业形成与发展、技术上的创新、市场需求的扩大和资本市场的发展，阐释了美国企业兼并的历程与特点；从马克思的资本集中理论，到结构主义与行为主义的争论与分歧，从当代经济学家们的若干理论，到中国学者对企业兼并的认识，跟踪考察了企业兼并理论的起源与发展；从企业是自组织系统的假设出发，界定了企业自组织兼并的内涵，提出了企业自组织兼并存在的条件体系，构建了市场结构、企业自组织兼并行为、产业绩效、政府调控的企业自组织兼并理论的SCPG分析框架，分析了企业自组织兼并理论的贡献。

After non-inoculated samples were treated with H2O2, peaks of protein had the trend of left-moving in resistant varieties, but trend of right-moving in susceptible varieties. So, when H2O2 existed, enchancement of POD activity impelled low-weight substance to polymerize high-weight protein in resistant varieties, but no difference in susceptible varieties.Samples from callus of five wheat varieties with varying degrees of resistance against wheat head blight were examined by FPLC.

对照样品在过氧化氢水浴(35℃)处理后，抗性品种的蛋白峰有&左移&现象，P_0峰有所提高，表现与赤霉病菌接种处理一致的趋势，因而，在H_2O_2存在的前提下，抗性品种中POD活力的提高促使小分子量物质聚合成大分子量的蛋白，而在感性品种中没有这些变化的出现。

There is no essential difference between the two, as the pool of metal around the hole surrounded by molten metal gravity and surface tension have to make holes to bridge the trend, while the metal vapor is generated by a continuous attempt to maintain the existence of holes.

从机理上看，这两种焊接方法的前提都是焊接时存在小孔，两者没有本质的区别，小孔周围为熔池金属所包围，熔化金属的重力及表面张力有使小孔弥合的趋势，而连续产生的金属蒸气则力图维持小孔的存在。

While the Addis hypothesis of work hypertrophy to excrete urea is erroneous, a more modern concept associated with glomerular hyperfiltration was proposed in the 1980s by Brenner.25 This hypothesis states that after any significant loss of renal function, surviving nephrons subsequently undergo functional and structural changes including increases in single nephron GFR and glomerular capillary pressure increases.

当Addis成果假设过度膨胀分泌尿素的观点是不正确的，Brenner在1980年代提出了有关肾丝球体高滤过率的最新观点25。这个前提陈述，在肾脏功能有任何显著的丧失之后，幸存的肾脏小过滤器也接著经历了机能上和构造上的改变，包含增加了一单位小过滤器的肾脏丝球体过滤率和提高肾丝球体毛细管压。

本文在现有文献和已有研究成果的基础上，综合运用了多学科的知识，从委托-代理理论出发，通过对中西方委托—代理模式的分析与比较，提出了在加快民营化进程，减少国有企业数量的前提下建立有效公司结构是解决代理问题的根本途径的观点。

Based on ready-reference and research, starting from principal-agency theory, with comprehensive implementation of many subjects and analysis and comparison between eastern-western principal-agency system, the dissertation points out building the effective corporate governance construction is the complete way of agent-problem-solving. Under the precondition that stimulation of privatized enterprises and reducing of state-owned enterprises.

Extensive research has been carried out under the hypothesises such as fixed number of constraints in one dynamic system, nondegenerative Jacobian of constraints, ideal and bilateral constraints. If one or more of these hypothesises are violated, inconsistency in state space may appear.

然而，目前有待发展的经典力学理论中有一些假设性的前提，例如约束的数目保持不变，约束的Jacobian非退化，约束是理想的，同时对含单边约束的系统研究甚少。

After analyzing their calculation principle, the authors believed that the reason for these differences was that the prerequisite calculating the stable-state geothermal temperature filed was untenable in some areas with possible unknown underground heat events, then the thermal Curie point isotherm derived from this method would not show the actual Curie point isotherm in such areas.

笔者认为造成这种差异的主要原因在于，在有可能存在未知热事件的地区，计算稳态地温场的前提条件并不成立，因而由这种方法计算出来的热居里面在这些地区并不能真正反映居里面的深度，从而形成了它与磁居里面的显著差异。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
