本文叙述了随机介质中标量波传播的路积分解的基本依据。
The basic principle of the path integral formulation for scalar wave propagation in random media is described.
因此，标量波并没有因为这样，他们的影响并不随距离减弱速度。
Scalar waves therefore do not have a velocity as such, and their effects do not diminish with distance.
本文主要研究高维空间中带有退化粘性的标量守恒律方程的光滑解的整体存在性，以及该解逼近强平面稀疏波的衰减率。
This paper is concerned with the decay rates of the solution to the strong planar rarefaction waves for scalar conservation laws with degenerate viscosity in several space dimensions.
