非简谐振动对二维系统玻意耳线的影响

THE INFLUENCES OF UNHARMONIC VIBRATION ON BOYLE CURVE IN TWO-DIMENSIONALSYSTEM

利用Collins模型,以氩为例,计算了在各种不同条件下二维系统的热力学函数.研究了二维系统在存在空位的情况下,原子不动、或平动、或作非简谐振动等情况的临界温度、玻意耳温度和玻意耳线等.所得的结果同由经验方程求得的结果相类似,与实际系统的实验值相近.

Making use of Collins model and taking Ar for example, in this paper. the author calculated the thermodynamical function of two-dimensional system considering the existence of vacancies, studied the critical point. Boyle temperature, Boyle Curve in the condition of motionlessness. translation and unhar-monic vibration of atoms. The results obtained are similar to experimental values and the results from empirical equation.
