The results: the phase transferring range of TiO2 is between 600-750℃; with the doping of tourmaline, the UV-VIS adsorption spectrum of Nd/TiO2 was basically not affected, and showed a gradual Einstein shift with the increase of calcined temperature between 300-750℃; OH intensity of Nd/TiO2 could be enhanced both in irradiation and in no irradiation when tourmaline was added in it; the doping of 0.6% tourmaline led to the best photocatalytic activity of Nd/TiO2 and the best photocatalytic effect appeared when calcined at 600℃.

结果发现TiO2的相变转化区间在600~750℃范围内；电气石掺入对Nd/TiO2材料的光吸收范围基本没有影响，在300~750℃范围煅烧后，随温度升高UV-VIS图谱有逐渐红移现象；电气石的加入使得Nd/TiO2材料在光照及未光照条件下都起到增强OH强度的作用；在Nd/TiO2材料中掺入0.6%的电气石获得最好的光催化活性，600℃下煅烧光催化效果较优。

However, the difference between Hongge and Xinjie is also apparent, perhaps reflecting the source difference in the mantle. Relative to the Hongge intrusion the Xinjie intrusion is more depleted in Nd isotope ratio and enriched in REE and LILE. The Xinjie intrusion plots in the first quadrant in Sr-Nd diagram, which shows the Sr isotope-enriched and Nd isotope-depleted slightly feature. This indicates that the source of the Xinjie intrusion may had the mantle wedge signature.

Based on the previous geological work, a large number of granitoid samples are carried on the Sm-Nd isotopic analysis. The results show that the εNd values of these granitoids occurred in Beishan Mountain area range from-16. 39 to +10. 89, some of which are characterized by the positive εNd value. It suggests that the crustal growth existed during Phanozoic in Beishan Mountain area, just like other regions in the CAOB.

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.
