infrared spectroscopic analysis meaning in English

红外光分析
红外光谱分析
红外线分光分析

Their properties have been investigated by using scanning electronic microscopy ( sem ) , differential scanning calorimetry ( dsc ) , x - ray diffraction ( xrd ) , thermogravimetry - differential thermal analysis ( tg - dta ) , infrared spectroscopic analysis ( ir ) , and gas chromatography ( gc ) , etc . the effects of the mulser ' s stirring rate and the emulsifier concentration on the properties of encapsulated pcms have been systematically studied , and nanopcms have been obtained by increasing the stirring rate or the emulsifier concentration . the influences of different nucleating agents on micropcm performances have also been investigated in detail to search for a suitable nucleating agent to prevent micropcms from super - cooling
首先，系统研究了乳化机转速和乳化剂浓度对胶囊性能的影响，并通过提高转速或乳化剂浓度获得相变材料纳胶囊；其次，系统研究了不同成核剂对微胶囊性能的影响，找到合适的成核剂抑制了相变材料微胶囊的过冷现象；再次，详细研究了环己烷对胶囊性能的影响，并通过添加适量环己烷提高了相变材料微胶囊及纳胶囊的耐热温度。
