磁场对惰性气体物态方程的影响

Effect of Magnetic Field on the State Equation of Noble Gases

计算了磁场作用下氦、氖等惰性气体的第二维里系数 ,发现磁场对惰性气体第二维里系数的影响较大 (可以达到 1 0 %～ 30 % ) ;当温度不变时 ,惰性气体的第二维里系数随磁场的增强而增大 ;当磁场变化到一定范围时 ,存在一个临界磁场 Bc,当外磁场 B <Bc时 ,第二维里系数随温度的增加而增加 ,当 B >Bc时第二维里系数随温度的增加而减小 .

The second viral coefficients of inert gases such as He and Ne etc. under the effect of magnetic field are computed. It is shown that the intensity of magnetic field and temperature have great effects on the second viral coefficients of the inert gases. When temperature is constant, the coefficients increase with the increase of magnetic field intensity. There is a critical magnetic induction intensity B c, when magnetic induction intensity B<B c, the coefficients increase with the increase of temperature ; when B>B c, they decrease with the increase of temperature.
