quantizing

In the Lorentz invariant coupling model of the interaction between nucleon N(antinucleon) and neutral meson π~0,the authors thoroughly analyze the moment regularization of N-loop propagator in the moment renormalization,and find that traditional minus-piding can be substituted by the matrix function expanding.

采用核子N(反核子N-)与中性介子π0相互作用的Lorentz不变耦合模型,对N-N-圈图传播子在“动量重整化方案”中的“动量正规化”作了深入细致的分析与考证,发现可以采用“矩阵函数展开法”来替代通常采用的“传统减除法”,并由此对N-N-圈图传播子函数中的“发散量”与“有限量”作了十分简捷有效的分离,获得了“重整化有限量”的一个具有“明确计算含义”的表达式。

Based on the characteristics of the superheated steam temperature of thermal power plant,a scheme of composite PID-fuzzy control system is put forward.

以火电厂过热汽温为对象,采用PID—模糊混合控制方案,为改善控制效果同时引入量化因子自调整,并应用MATLAB的SIMULINK对系统进行了仿真分析。
