This paper introduces "the fault analysis and determination method for new weaponry", and develops the theory to analyze the possible causes of faults with logic analysis method.

3—2005 Limits and measurement methods for emissions from light-duty vehicles(Ⅲ,Ⅳ phases for China),the effects of the differences of emission limits in type I test between phase Ⅲ and phase Ⅳ and the different judging methods for different cases on the result of conformity of production(COP) assessment are analyzed.

In allusion to the problem that the behavior of the equations will become abnormally difficult with the rise of exponent number measuring with condition number,the reason of the engendering of ill-conditioned linear equations has been analyzed and a judging method has been suggested.

Analysis on some familiar judgement methods about interchangeability of combustible gas;

The deployment uniformity judgement method of a kind of cluster warhead is analyzed.

with the help of matrix number and matrix music radius concepts,combined with the conclusion about the limit and numeral progression,the paper gives judgement methods of matrix progression unanimous convergence.

A judgment method for the satisfying consistency of linguistic judgment matrix;

With the help of matrix number and matrix music radius concepts and combining with the conclusion about the limit and numeral progression,two judgment methods of matrix power series absolute convergence are given.

With the discussion of extreme value problem of the multiple-valued function,and the popularizing of extreme value theory of the two-value function,This paper obtains differentiation rule about the extreme value of the multiple-value function,and illustrates the apllication of the theory with the example,providing proper guidance for the teaching of calculus.
