First, this paper, in the field of intrinsic geometry, studies the geometric problems on garment design, as well as applies the frame and semi-geodesic coordinates to prove the fundamental theorem of being a developable surface.

文中首先在内在几何学的层次上，研究了服装设计所涉及的几何学问题，应用标架与半测地坐标方法证明了曲面成为可展面的基本定理，研究了可展面的分类及其性质，考虑到服装三维几何造型的需要，证明了组合式可展面各组成片相切连接条件的命题，作为构造可展面的理论依据，证明了单参数平面族的包络面必为可展面的命题，在此基础上发展出服装几何造型的"刮大白"方法以及相关的三种构造可展面的解析方法。3D→2D的变换是三维服装CAD的重要内容之一，其几何学实质是曲面的定长映射，文中总结了定长映射即可展面在平面上展开的基本准则，在这一准则的指导下，结合服装设计与相关领域的要求，讨论了可展面在平面上展开的解析方法与数字方法，上述内容确立了服装设计几何学的基本框架。

This paper not only in theory, but theory into practice, through the way of cases, the problem of common crime more detailed classification, through analysis of typical cases, and in different list for circumstance, common crime of general solution of this proposition, in order to make innovations.

本文并非单纯进行理论的阐述，而是理论融于实践，通过案例的方式，对加重犯的共同犯罪问题进行更为详细的分类，通过典型案例的列举与分析，在不同情况下，展开对加重犯的共同犯罪这个命题的一般解法，以期有所创新。

Consideration of size leads to a general proposition for quadratic forms in normal variate which gives conditions for a class of test statistics, which are chi-square under

正态变量的二次齐次式给出了一类统计检验的条件，对大小的考虑引出了一个对其一般性的命题，即在分类正确若为卡方分配，在分类有误时将有向上偏误。

Consideration of size leads to a general proposition for quadratic forms in normal variate which gives conditions for a class of test statistics, which are chi-square under correct specification, to be oversized under misspecification.

正态变量的二次齐次式给出了一类统计检验的条件，对大小的考虑引出了一个对其一般性的命题，即在分类正确若为卡方分配，在分类有误时将有向上偏误。

In this paper, the background of fake information diffusion in public crisis management was firstly analyzed, and then three basic propositions and three hypothesis of simulation were concluded. Then, the management countermeasures of fake information diffusion in public crisis were classified as fifteen types according to the types of strategy and executive ability, and then fifteen corresponding simulation schemes were put forward. Meanwhile, a management simulation model of fake information diffusion in public crisis was constructed and used to phenomenologically simulate the scenarios and validity of five among these fifteen management countermeasures. At last, these simulation results were contrasted and analyzed, and five novel but meaningful conclusions were drawn.

首先对公共危机伪信息特殊性及其管理复杂性进行分析，得出论文研究的三大基本命题与三大研究假设；在此基础上，一方面分析了混沌理论方法在公共危机伪信息管理仿真中的适用性，并根据混沌情景预测方法构建了公共危机伪信息扩散的管理仿真模型，另一方面依据所提出的基本命题与研究假设，从管理策略与管理执行力度两方面对公共危机伪信息管理模式进行分类，形成了十五个仿真方案；最后利用所构建的仿真模型其中的五个仿真方案的管理绩效与扩散情景进行唯象仿真，并对仿真结果进行横向对比分析，得出五大结论。

The proposition and classification of propositional forms are a very complicated problem.

命题及命题形式的分类是一个相当复杂的问题。

Two complemented lattices L_1, L_2 are said to be of the same "type" if they have identical sets of tautologies.

一个具有最小元O及最大元I的格L，如果在其中又定义了一个单值的1元运算&′&能适合O′=I，I′'=O，则称L为一可补格，一个命题演算良构式A(设只含命题连接词A，V，～)，如果命它的变数在L中任意取值且将A，V，～分别解释为L中的运算∩，U，′时，A永远得到值I，则称A为L上的恒I式，当两个可补格L_1，L_2上的恒I式集相同时，称L_1，L_2为同型的，本文就是讨论可补格按同型关系分类的问题，所得结果如下：定理设有限可补格L_2适合条件：，存在一良构式A能使则任一可补格L_1与L_2同型的一个充分必要条件是：(A_1)。

In this paper, the authors propose a temporal approaching relation and give a sort of temporal relations of propositions, based on Shoham s temporal logic, they propose a temporal logic which can describe uncertainty relation and is based on time--point and time--interval in proposition and first order case.
