摘要
Burgers equation in random environment is studied. In order to give the exact solutions of random Burgers equation, we only consider the Wick-type stochastic Burgers equation which is the perturbation of the Burgers equation with variable coefficients by white noise W（t）=Bt, where Bt is a Brown motion. The auto-Baecklund transformation and stochastic soliton solutions of the Wick-type stochastic Burgers equation are shown by the homogeneous balance and Hermite transform. The generalization of the Wick-type stochastic Burgers equation is also studied.
研究了随机环境中的Burgers方程.为了给出随机Burgers方程的精确解,只讨论变系数Burgers方程的系数经白噪声W(t)=B·(t)扰动所得的Wick型随机Burgers方程(B(t)是Brown运动),利用齐次平衡原理和Hermite变换给出了Wick型随机Burgers方程的自Bcklund变换和随机孤立子解的精确表达式,同时也研究了一般情形的Wick型随机Burgers方程.
