Firstly, the mechanism of heat transfer enhancement by oscillation heat surface is discussed in natural convection scene. For different oscillation amplitude and Rayleigh number, the frequency that the heat transfer rate of oscillation heat surface is higher than non-oscillation condition is found and called critical oscillation frequency. The limitation enhancement of similar physical model is still researched by this study in mixed and forced convection scenes for different amplitude and Grashof number. Generally, that a heat surface subject to a oscillation motion is advantageous to convective heat transfer is a well-known tuition.

首先探讨在垂直管道内振动高温面於自然对流领域内提升高温面热传效率的机制，并且针对不同的振幅与雷利数求得加入振动条件后，高温面散热效果可以优於稳态非振动高温面散热效果的临界振动频率；进而探讨当垂直管道流进入混合对流与强制对流范围时，在不同的振幅与葛瑞秀夫数下，亦可发现加入振动条件后，振动高温面之散热效果可以优於稳态非振动高温面散热效果的临界振动频率。

oscillation：振动

认为H+流的振动(oscillation)可能参与了根的回旋转头运动. 菌根是土壤中特有的真菌与植物根的共生联合体. 植物有了菌根,就可以通过无数细长菌丝和菌索吸收土壤中的营养和水分,扩大根系的吸收面积,提高吸收能力.

oscillation：摆动

此观念是在说;借着一种摆动 (oscillation )的过程,仆人的形像移动于团体及其个人的代表之间. 在Robinson 的观念,这个作为以色列代表的人乃是忠心的先知自己和他忠诚的门人. Eissfeldt 的说法则较含糊;他以为可能是他们的祖先中的一位.

oscillation：震荡

专家们犯了一个错误,他们会辩解说他们不可能真的预计到会发生什么事情,他们估计到了地轴偏转,但没有估计到地壳震荡(oscillation). 宇宙飞船是进入了抗引力隧道,但又被拉进了由于天体碎片重新进入大气层引起的大气'震荡'(Back-wash)中而被天体尾部的无数碎片所击中.
