波段

According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.

从模拟结果中得知，薄膜型结构之太阳电池可以经由AuGe/Au之金属反射层，再次将未被基极层完全吸收之入射光反射回太阳电池，使得薄膜型结构在长波段的外部量子效率获得提升，这结果显示薄膜型结构太阳电池可利用AuGe/Au之金属反射层在长波段的高反射率，改善使用较薄基极层时，无法将入射光完全吸收的缺点。

What\'s more, different intervals of UV have their own characters in influencing DNA: the damage to some bases by UVA may be more serious than that by UVB, and UVB did more severe damage to some deoxyribose than UVA; however, as far as the pyrimidine bases are concerned, the damage by UVB is by far more serious than that by UVA. These results may indicate that there are preferential damaging sites on DNA molecules caused by UVA and UVB irradiation. Moreover, with UVA or UVB irradiation for a long time, the photoreactivation of DNA occurred. The serious damage to deoxyribose and bases by UVB and UVC may confirm the conformation of cyclobutane pyrimidine dimers and (6-4) photoproducts.

而不同波段紫外辐射对DNA的损伤各具特点并且差异明显，UVA对一些碱基的损伤比UVB要严重，而UVB在对脱氧核糖和磷酸盐的损伤上又比UVA要严厉，但就嘧啶碱基来说，UVB对它的损伤远大于UVA，这似乎表明了不同的紫外波段对生物大分子DNA的损伤是有选择性的。

Fitting analysis with a power function for the pigment concentration and absorption coefficient showed that the absorption coefficients at 412 nm and 440 nm exhibited higher correlation with pheophytin concentration than chlorophyll a, but contrary at 675 nm.

色素浓度与吸收系数进行乘幂函数拟合分析表明，412、440nm波段吸收系数与脱镁叶绿素浓度拟合相关性高于叶绿素a，而675nm波段相反。

While the proportion of pheophytin in total pigment concentration increased, the absorption peak in the blue region of spectrum deviated from 440 nm to near 412 nm. The absorption peak height in the blue region was mainly influenced by pheophytin concentration, whereas the height in the red was decided more by chlorophyll a concentration.

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—60μm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。
