Normality,quasi - Borel exceptional value and defective number relation with multiple values of a K - quasimeromorphic mapping on a plane are investigated by using of covering surface theory.

On finite values and total deficiency of linear differential polynomials;

Inequality、Deficiency and Uniqueness of Meromorphic Functions;

To get the value distribution of meromorphic function to the polynomial function,the constants of the counting function in the inequality is generalized to polynomial function based on the Nevanlinna theory and function theory analysis method,and get the corresponding deficiency sum upper bound.

Using Nevanlinna theory of the value distribution of meromorphic functions, we investigate the problem of the existence of non-admissible solutions of a type of systems of algebaic differential equations and improve the estimation of non-admissible solutions by deficient number δ(a,w).

Further,if we consider the deficient number of f(z),then f(z) can be determined by four sets ( ,f).

On the meromorphic functions with maximum function defects;

In the theory of meromorphic functions and their value distribution, there are two kinds of defects relative to complex numbers, the relative defect and the absolute defect.

The paper discusses the defect and uniqueness of the derivatives of meromorphic func- tions of finite order satisfying.

On the Deficiencies and Differential Polynomials of Meromorphic Functions;

Relationship of the deficiencies of a kind of linear combination of meromorphic functions is discussed.

Through the determination data statistics of the flavoring materials of Fen jiu Liquor,it was concluded that the main trace components and its quantity relative ratio relationship had close effects on sensory quality of the liquor.
