气泡室中"胚胎"气泡的联并成长为可见气泡的理论计算

借助岛的联并理论,可以很好地解决气泡室中"胚胎"气泡成长为可见气泡问题.理论计算表明,联并后的大"胚胎"气泡在成长为可见气泡的过程中,气泡的半径不仅与工作物质如液体的表面张力系数、饱和蒸汽压和流体的沸点有关,而且还与"胚胎 "气泡从其周围吸收热量和"胚胎"气泡联并的个数有关.理论上可以合理解释能量相同的中子和质子入射到气泡室所产生的径迹粗短;也可以合理解释电荷数较多的入射粒子较能量相同但电荷数不同的入射粒子,其在气泡室中径迹上气泡的半径要大.

Theory calculation of combination of "Embryo" bubble growing-up visible bubble in bubble camber

By aid of island combination theory of "embryo" bubble, it is resolved well the quesition which "embryo" bubble grows up a visible bubble in the bubble camber. Through theory calculation it is shown that radius of the big "embryo" bubble combinated not only relates with work matter such as surface tension coefficient, saturation vapour pressure and boiling point of liquid, but also does absorbing quantity of heat and the numbers of "embryo" bubbles combination. It is explained reasonably that the radius of bubbles in bubble camber is different for the same energies of neutrons and proton. The track of neutron in bubble camber is long and thin, and the track of proton in bubble camber is wide and short. It is also explained reasonably that the bubble radius of the incident particles with more charges which there are the same energies will be wider than that of the incident particles with less charges in the track.
