In this article, the molecular vibration frequencies are determined by Laman scatters experiment, then the molecular structure is obtained. 該文通過(guò)樣品實(shí)驗，用拉曼散射測定分子的振動(dòng)頻率，進(jìn)而分析出物質(zhì)的分子結構。
The main object of this paper is to investigate the natural frequencies and model shapes offree vibrations of shallow spherical shells on the two-parameter elastic foundation. 本文研究雙參數彈性地基上扁球殼的自由振動(dòng)頻率和振型，推導了計及地基慣性力影響的扁殼自由振動(dòng)控制方程。
