Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.

从119个菌株中分离筛选出了6株细菌和5株霉菌，它们可以在含有木质素的培养基上良好生长：细菌分类学鉴定结果为X1、X2和X3：假单胞菌属，X4和X5：黄单胞杆菌属，X6：枝动杆菌属；对6株细菌降解木质素性能进行了初步的研究，选定X2和X4为实验用菌种，两株菌适宜的生长温度为30℃，最适初始pH值为7；经紫外线照射诱变法处理，可使它们产生的三种木素分解酶活性均有明显的提高，细菌增长速率比诱变前明显提高。

In addition, the recombination for large numbers of charge carriers would occur in the volume or on the surface of TiO_2. Therefore, the extension of the photoactive wavelength region of TiO_2 into the visible region and improvement of quantum efficiency are desirable for popularizing more TiO_2 photocatalyst, especially under solar light for industrial areas or poor interior lighting illumination in living spaces.

但纳米TiO_2具有较宽的禁带宽度，只能吸收太阳光中5%左右的紫外线，而太阳光中近45%的可见光在处理污染物中却得不到有效利用，因此太阳能的利用率较低，这就限制了其实际使用范围；另外，TiO_2半导体载流子的复合率较高，因此量子效率较低。

It developed for military affairs first in Occident .It utilizes the characteristic of NUV spectrum (240-280nm) that UV spectrum of object is much greater than that of solar radialization in the aerosphere. Double spectrums imaging system gets UV and visible images to identify the object and background. Image infusion is a essential step of succedent image processing.

它利用中紫外区的&日盲&(240—280nm的中紫外)特性，即目标发出的紫外线远远强于太阳的紫外辐射，通过双光谱图像检测系统观察和检测该波段的紫外目标信号与背景可见光图像，并利用图像配准与融合技术，把紫外光图像准确地定位于背景图像，形成合成图像达到检测目的。

The ideal induction efficiency of UV irradiation (200 W/m〓) on improvement of salidroside production of the culture is carried out for 20 min at day 15 after subculture. The induction efficiency of the extract of the root of Rhododendron chrysanthum is higher than that of Saussurea alpicola.
