Through the source code audit such as RATS software can find the flaw information of level of partial source code, but after all the majority that software of source code audit searchs spills over for the existence buffer such as Strcpymemcpy the C function that involuntary discharge of urine has, the measure that adopts audit source code so will undertake flaw is dug is coefficient of a possibility very small leak digs a technology, and the flaw that although also can find a few software,checks in the light of the black box of software, but possibility coefficient also is met lesser, a few undertakes flaw is dug idea that are in abroad already slowly promotion writes black box to check code for oneself, the module of a certain function that is aimed at system or software next undertakes modular flaw digs a technology.

通过RATS等源代码审计软件可以找到部分源代码级别的漏洞信息，但是究竟源代码审计软件寻找的多数为strcpymemcpy等存在缓冲区溢出遗患的C函数，所以通过审计源代码的办法来进行漏洞挖掘是一个可能性系数很小的漏洞挖掘技术，而针对软件的黑盒子测试虽然也能找到一些软件的漏洞，但可能性系数也会较小，在国外的一些进行漏洞挖掘的办法已经慢慢的提升为自己写黑盒子测试代码，然后针对系统或软件的某个功能模块进行模块化的漏洞挖掘技术。

Using coupling model M4RC3 and improved MM4, a dust storm and a snow storm were simulated respectively. The effects of radiation parameterization and microphysics parameterization on development of dust storm and snow storm mesoscale system were discussed. Dynamical and thermodynamical diagnoses were also carried out to study the developing mechanism on the systems.
