本研究提出了微孔曝气最优气泡群的确定方法，并采用最大气泡群常数终值来表征该气泡群。
This paper puts forward the calculation of optimal bubble group and uses maximum bubble group constant to evaluate this group.
发现带电粒子以电荷群的作用力为向心力做圆周运动时，有一常数乘以频率等于带电粒子的动能。
It finds that there is a constant multiplied by frequency which is equal to the kinetic energy, when a charged particle does circular motion for the centripetal force product by the charge group.
