摘　　要：通过对理想玻色粒子系统物态方程的推导和修正,再利用系统临界点的计算办法,分析发现:实际玻色粒子系统在理论上存在临界点,但实际中不可能存在;从理论上讲,玻色粒子的直径越大,临界点的体积越大,在同样的温度和压强下,临界点的视界越大,反之则相反;临界压强的数值与粒子的有效直径成平方反比;玻色粒子系统的临界温度与粒子的有效直径无关.Through the deducing and amending of the equation of material status of ideal Bose particle system,the computational method of system-critical point was put into use.It was found that： firstly,theoretically,there is a system-critical point in the ideal Bose particle system,but it can＇t exist in reality;secondly,in theory,the larger diameter of Bose particle,the larger volume critical point,and the larger field of vision at a constant temperature and pressure,and vice versa;thirdly,the value of critical pressure and effective diameter of particle are in inverse ratio and the critical temperature has nothing to do with the effective diameter of Bose particle system.
