vibrational band meaning in Chinese

振动带
振动谱带

Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower , and therefore most of the energy from carbon stars are radiated between 1 to 60um range , in which the vibrational and ro - vibrational bands of many molecules also lies , the study of infrared spectra in this wavelength range is very important to reveal chemical compositions , dust formation process , the atmospheric structure and evolutionary status of stars
碳星光球的有效温度不超过3000k ，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1 ? 60 m的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。
