The phenotype values of the major gene and polygene mixed inheritance of quantitative trait demonstrate multimodality, showing the mixture of more than one normal distributions, that is corresponding to more than one major gene genotypes, so the selection is different from common quantitative trait in model hypothesis and analysis.

主基因-多基因混合遗传的数量性状，其表型值呈现多峰性，表现为多个正态分布的混合，即对应多个主基因基因型，其选择与普通数量性状的选择在模型假定以及分析上都有很大的不同。

The assumption of the variable tendency of slip-line in active zone is made based on the numerical results. Combining the slip-line equations and boundaries, the formula of bearing capacity is deduced which can consider the density of soil. The formula of bearing capacity of strip footing on ponderable soil is also deduced assuming that the slip-line field of ponderable soil is the same with that of weightless soil, which is proved to be an upper-limit solution, as its the same with that deduced by the upper-limit method in Prandtl mechanism.

在数值计算结果的基础上，对有重土地基主动区滑移线变化趋势进行了合理假设，根据边界条件和特征线方程求得了条形基础极限承载力的解析表达式，该表达式可以计算考虑土重度的条形基础的极限承载力；获得了不考虑重度对滑移线场影响时(即有重土在普朗特尔滑移线场下)极限承载力的解析表达式，该表达式与普朗特尔机动场对应的极限承载力上限解的表达式相同，这就从理论上证明了在土重度对滑移线场没有影响这一假定前提下得到的极限承载力是一个上限；(3)利用上限定理求解了极限承载力的最小上限。

Compare the most differences of purchase and pooling interest accounting from six aspects which is hypothesis principle, principle of disposal, the consequences of accounting, theoretical basis, information disclose and influence of finance statement.

第三章在简要介绍购买法和权益联营法的涵义及其特点的基础上分别从会计处理假定前提、处理原则、处理结果、理论依据、信息披露、对财务报表的影响六个方面比较研究了购买法和权益联营法的主要区别，并对它们的优缺点进行评价，同时也对它们在国内外的运用现状进行了说明。

Through the comparison between R. M. Hare's ethic deductive theory and the two versions of rational prescriber's theory, the writer finds that utilitarianism can be derived from a theory of the type of rational choice only if the hypothesis is held that the chooser is in all parties' places with equal probability.

通过比较黑尔的道德推理理论和两个版本的理性立约者理论，可以发现，理性选择论类型的理论，如果要导出功利主义的结论，都需要假定选择者以相等的概率处于有关各方的地位上。
