低频声子谱拉曼测试腔的设计与研制

Design and think of testing chanber for low frequency phonons

根据一些物理原理，对低能声子（≤０．０２５ｅｖ）的拉曼测试提出了一套设计思想，免除了空气中氮、氧分子对低频区（≤１８０ｃｍ￣（－１））的干扰影响，从而开拓了Ｒａｍａｌｏｇｓｙｓｔｅｍ中１４０３双单色仪探究低频声子的能力。

According to the physically principles，there had been given ideas，in order to avoid the air scattering （inclding Oxygen anf Nitrogen molecule），and then the low frequency（≤120cm^(-1)）phonons can be presented in Raman spectra，reliably and truly． So that the functions of Raman system for 1403 dotible—monochromator have been developed further， too.
