A method of minimization to a class of boundary-value problems of differential equations with convolution is given by using potential operator defined in a real Banach space, separating coupled variable; the transformed minimum principle on Laplace transformation and the weighted minimum principle in original place-time domain are established.

In addition, using the variable-coupling schemes and the K-B space scalar coupling scheme, we i.

Attitude control is implemented on statically indeterminate and multivariable coupling air spring vibration isolation system.

The second order coupling deformation variables, which have little effect on the dynamic behavioars of the system, are kept in the deformation.

This paper describes and sorts the methods in analyzing different sympathetic nerve activity, and introduces the research development of several groups in statistical analysis, spectral analysis, nonlinear dynamics analysis and multi-variable coupling analysis.
