The processes have been extended to a "slowly varying" vertical stratified medium, and the W.

进而对“缓变”的垂直分层运动介质作了类似讨论，求出声场的w。

Relative importance of each component contained in the second-order slowly varying forces is also discussed.

探讨了二阶慢漂力中各成分在不同频率时的相对重要性。

Secondly, the obtained results were applied respectively to mine hoist systems with slowly varying mass and with quadratic or cubic nonlinear spring.

其次，将得到的结果分别应用于有平方、立方非线性弹性力的质量慢变的矿井提升系统。
