stationary wave 【物理學】定波,駐波。

stationer

Using an l2 energy method proves that the solutions of the general initial - boundary problem to this relaxation model converges time - asymptotically to a stationary wave or a rarefaction wave or superposition of these two kinds wave for small perturbation 對此松弛模型,用l ~ 2 ?能量方法證明了在小擾動的情形下,相應的一般初邊值問題的解漸近收斂到一個穩定波或一個稀疏波或這兩種非線性波的疊加。

The aim of the paper is that providing evaluation evidences to find early the place and degree of fatigue accumulation damage through researching the relation between fatigue accumulation damage and magnetic memory effect based on stationary wave 本文的目標是通過基于駐波疲勞累積損傷與磁記憶效應關系的研究,為早期發現這類構件的疲勞累積損傷部位及其嚴重程度提供評價依據。

The key technique include nip signal ' s generation , serial port 422 communication , control system data acquisition and processing , stationary wave ratio of antenna , sending and receiving signal ' s attenuation of antenna and so on 其關鍵技術包括nip信號產生, rs - 422串口通信,控制系統各模塊數據采集和處理,機載天線駐波比及收發信號衰減測量等。

The sound absorption coefficiet of osb was tested by the stationary wave method . the results showed that the osb had good sound absorption property compared with brick and concrete 采用駐波管法測定定向結構刨花板的吸聲系數,分析比較了定向結構刨花板與磚、混凝土吸聲性能的差異。結果表明,定向結構刨花板具有良好的吸聲性能。

A series of testing experiments are made to check the performance of the model , including the simulations of a stationary wave and a plunging wave rush on the slope beach 其中包括駐波的模擬實驗,卷波的破碎模擬實驗和一組isope的官方測試( officialbenchmark )模擬實驗。

Stationary waves are distinct from the progressive ones wherein the waves move across the body of water ? as if we had dropped a pebble in the dish of water 駐波與前進波不同,在后一種情況下,水波向四周傳去?就好象我們曾向盤中投下一塊卵石時的情景一樣。
