本文推广了Sears液体巡游振子模型的基本方程，使之与涨落耗散第二定理相一致。将Sears处理中的7个参数减少到5个，并对液氩的速度谱得到了较好的结果。正如在西尔斯的计算中，随机力相关强度的最佳值比从Lennard-Jones势计算的值大一个数量级。
The basic equations of the itinerant oscillator model of liquids due to Sears are generalized to be consistent with the second fluctuation-dissipation theorem. The number of parameters is reduced from seven in Sears's treatment to five and, moreover, a better result is obtained for the velocity spectrum of liquid argon. As in Sears's calculation, the best value for the intensity of the random force correlation is greater by an order of magnitude than that calculated from the Lennard-Jones potential.
