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
碳星光球的有效溫度不超過3000k ，同時較大的質量損失率形成了富碳的塵埃殼層，以致於它的輻射能量主要集中在1 ? 60 m的紅外波段上，並且許多分子的轉動振動能譜也集中在紅外，因此在紅外波段的研究對揭示碳星化學成份及其分佈、塵埃形成過程、恆星大氣結構和演化狀態都有十分重要的意義。 -
Based on the theoretical analysis and experimental researches, it is presented that the wider spectra are resulted from the many fluorophores with large numbers of vibrational energy levels on the ground level in the blood cells, and the reduction of the spectral intensity is due to the reabsorption of the blood cells and the energy transfer of the collisions between the fluorophore and another one or other macromolecule. on the other hand, when the concentration of the blood cells is increased, the reabsorption of the blood cells, the secondary fluorescence due to the reabsorption and the influence of the concentration on the energy levels of fluorophores are all the factors of the red - shifted spectral peaks
在進行理論分析和研究的基礎上，提出了因血細胞中存在多種熒光團，且這些熒光團的電子能級上又存在大量的不同的振動能級，從而導致被激發的熒光團發出較寬的熒光光譜；血細胞濃度的增大，熒光團以及其他大分子之間的距離變小，造成它們之間因碰撞的能量轉移概率加大，因而易產生熒光猝滅，結果導致熒光強度的變小；血細胞溶液中重吸收所導致的熒光猝滅和二次熒光發射，以及血細胞濃度的變化對其中熒光團能級系統的影響都是導致熒光峰值波長「紅移」的原因；進而研究了led光誘導血細胞產生熒光光譜的機理。 -
