With the view of the optimal approximation for the formed beams, the radiation pattern and the field distribution in the focus zone of Fresnel zone plate antenna approximation with the fields of the linear array have been studied based on the methods of weighted residue and Prony,which suit for the approximation for the real patterns of various Fresnel zone focusing configuration.

Based on the representation of interval rational Bezier curves and surfaces and by a serial of mathematical transformation, the degree reductions of them are converted to those of polynomials with upper bounds, then several algorithms are presented, with linear programming and optimal approximation methods.

As regards to our country,the optimum scheme is to set up suggestive clause about "act that is liberal in cause" in the general provisions of criminal code,and to set up the cause of the crime of full intoxication in the chapter of crime against public security.
