摘要:

The Weeks–Chandler–Anderson perturbation theory is derived for one‐dimensional Lennard–Jones systems. Its predictions are tested with molecular dynamics calculations on the full and repulsive Lennard–Jones potential. It is found that the prescription for the reference fluid is in excellent agreement with the computer calculations and that the high‐temperature approximation for the full Lennard–Jones system is a good one at high temperatures.
