A delaunay-based method for voltage-gated potassium channels classification and structure recognition;

Aiming at the problem that the rotational response is difficult to measure in structural identification,an approximate algorithm based on Neumann expansion theory is developed for rotational response identification.

Aiming at the problem that the rotational response is difficult to measure in structural identification,an improved approximate algorithm based on generalized inverse matrix theory is developed for rotational response reconstruction.

The Form and Development of the Population Sex Structure in Taiwan;

In this paper,a predator-prey system with sex structure is investigated,sufficient conditions for permanence and extinction of the system obtained,sex ratio under different capturing rate studied and conclusion made that sex ratio is related to the capturing rate of predators.

By using the methods of documentary,questionnaire and mathematicas statistics,this paper studies sex structure of population and sports population in Shanghai,analyzes their characteristics,causes and potential problem of society.
