如果你看看波长更长，到红外光谱的一部分，该吸收带是由特殊的分子。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

According to the calculated proportion of aniline and dye, if the other reaction condition is maintained, and the proportion in electrolyte is changed, the DS-PAn film with different sensation properties can be obtained, i. e. absorption range and intensity in visible spectrum can be controlled by the proportion of aniline and dye.

实验证实，可以通过预先计算苯胺与染料的比例，在电解液中改变苯胺与染料的比例，保持其他电化学反应条件不变的情况下，在经过一定时间反应后，可在多种衬底上生成不同增感效果的DS-PAn薄膜，同时此薄膜在可见光区的吸收谱带的宽度和强度可由聚苯胺与染料的比例来控制。

These substances can be distinguished easily based on the terahertz absorption spectra. The measurements suggested that even minor changes in the molecular configuration and chemical composition lead to distinct differences in THz spectrum.

实验结果显示取代基的位置和其自身的性质对化合物太赫兹吸收光谱有明显的影响，表明分子构形的微弱变化会导致太赫兹光谱的显著变化。

By the comparison of electronic spectrum and Z-scan of different substituted MPc and MNc, the peripheral substituted MNc had better nonlinear optical properties. It provided a new method to the improvement of the performance of reverse saturable absorption of the laser protective materials.

对不同金属轴向取代的萘酞菁化合物的电子光谱和Z-扫描进行了横向比较，并对相同取代基、金属轴向取代的酞菁化合物和萘酞菁化合物进行了纵向比较，发现周围取代的金属萘酞菁化合物具有较好的非线性光学性能，为提高材料的反饱和吸收性能提供了一种新的途径。

This after-shocked value of reflectivitywill influence on the confidence of calculated spectrum absorption coefficient,and its value is then of important significance.
