摘要：

We estimate analytically the density of solitons in a zero-pressure, infinite Toda lattice at thermal equilibrium. Our prediction is in close quantitative agreement with the results of recent simulations by Muto, Scott, and Christiansen [Phys. Lett. A 136, 33 (1989)]. In particular, at low temperature, the dependence of the soliton density on the temperature follows a T1/3 law
