In this article, by exploiting flanking markers through the widely applied half-sib design, we have developed the structures of three variance components, i.

The variance component analysis revealed that the ratios of additive genetic variance to phenotypic variance of the majority of economi.

Based on the differential equations and the system of difference equations,the mathematical model of the procedure of the resonant rise of thyristor parallel resonant intermediate frequency power supply was established,then the analytical solutions of the transient and steady state variables were obtained.

This paper was concerned with the following discrete system,by using the theory of the fixed-point index,we investigate a boundary value problem for three-order nonlinear difference systems with parameter,and the theorem of existence of positive solution is given.

This paper is concerned with a class of third order difference systems with Dirichlet boundary condition.
