Thus, the infrared spectra analysis can reflect the relationships of rhizobia, but in practice, there were some difficulties. 因此,红外光谱分析在一定程度上可反映根瘤菌的分类地位,但实际应用起来,仍有一定的困难。
The tribochemical changes of dodecane and stearic acid in the course of friction was studied through tribology experiments and infrared spectra analysis. 运用摩擦学实验和红外光谱分析相结合的方法,考察了十二烷和硬脂酸在摩擦过程中发生的化学变化。
