1. Introduction

2. The Quartz Wind （石英风）

3. Rayleigh Streaming

概念1：Stokes layer（slip velocity：$$U=U(x)e^{it}$$）

概念2：Reynolds stresses

fluctuating flow, frequency $$\omega$$，fluctuating velocity amplitude $$U_0$$

streaming velocity $$u_s$$

$$u_s = -\frac{3}{4}{(1-i)U^\frac{d U}{dx} + (1+i) U \frac{d U^}{d x}}$$

划重点：The streaming velocity created by the Reynolds stresses persists beyond the Stokes layer
