All these are the trigger mechanism of the severe convection and the squall line weather process. The strong instability of low level, the outbreak of low level jet and the core of the LLJ moving southeastward quickly, convective available potential energy and vertical helicity high center are indicative to the strong convection weather.

The Paper firstly, discusses the theories of quality management, arranges and analyses the basic philosophy of guaranteeing teaching quality of Master of Education in general. By retrospection the development of the graduate education in the United States, the type and major of Master of Education in the United States are identified, and the main characteristics of the graduate education in the United States are summed up. And these characteristics include: appropriate training objectives, standards of graduate admission which require the capacity for the first, curriculums which are set pragmatically and flexibly, tutors which are selected strictly, different training models, a variety of teaching methods, internal quality assurance system which is standardized and effective, a wide range of external forces of quality control.

Secondly, the properties of output sequences of stop-and-go clocked combiners are discussed. It is proved that the output sequences are stationary and obey strong law of large numbers and central limit theorem. Using the probabilistic model properly built, we analyze the rate of coincidence between the output sequences of two kinds of generators with basic operations and corresponding LFSRs sequences. All the computational formulae are derived. A recursive algorithm for efficiently computing the poster probability of partial input strings and corresponding joint probability is introduced. Moreover, divide-and-conquer attacks on this kind of generators which reconstruct the initial states of the input stop-and-go generators individually are proposed.

其次，分析了一般钟控停走组合生成器输出序列的概率分布性质，证明了生成器的输出序列是严平稳的，且服从强大数定律和中心极限定理；考察了钟控加法型组合生成器和钟控乘法型组合生成器的输出序列和相应的常规钟控下线性移位寄存器序列之间的符合率，给出了符合率的具体计算公式；给出了组合器输出序列段和输入序列段之间的联合分布以及部分输入序列段的后验概率的有效递归算法，进一步提出了利用后验概率对钟控组合生成器进行分别征服相关攻击的方法。

As the economic globalization and network internationalization developed further, it is important to control the transnational crime effectively , as to concern the international peace, security and economic development . China lies in the center of Asian-Pacific region, propose cooperating in combating the best model of the transnational crimes cooperation in this area, is the motive of this text.
