The results showed that extremely cold rain and snow weather of Sichuan Basin was related well to the variations of water vapor、 frontogenetic function of Yangtze River Basin. at the mid-lower level of the troposphere, especially at 700 hPa level, there was water vapor convergence exiting lastly in Sichuan Basin for long time. And the time of convergence of water vapor was congruous with of cold air in Sichuan basin, and provided the water vapor conditions for the occurrence of low-temperature disaster.

结果表明：四川盆地的低温雨雪天气与南来的水汽变化及长江流域的锋生作用有密切关系，在对流层中低层700hPa上，四川盆地长时间存在稳定的水汽辐合区，水汽辐合的时段基本与盆地冷空气活动时间段一致，这为低温降水的发生提供了水汽条件。

The minimum potential region of water vapor transport vector correspond to intense heavy rainfall region, and the water vapor convergence of the heavy rain region is supplied by the hemisphere scale water vapor transport, indicating that even for a regional severe flood it must gain water vapor supply from very extensive regions.

水汽通量的势函数极小值区对应强降水区，并且暴雨区的水汽辐合是由半球尺度的水汽输送造成，这表明，即使对于该年背景的区域性大暴雨/洪水，它也必须从极大范围地区获得水汽供应。1999年水汽辐合的中心位置较1998年偏东偏南，这使得1999年降水较1998年偏南。

Firstly, the GPS data in Naqu, Gaize, Deqn, Tengchong, Mengzi and Simao are processed, the change of remote sensing water vapor using six ground GPS receivers in Tibet Plateau and Yunan province are analyzed, the results based on GPS with those based on the radiosonde data are compared, and the relationships between the amount of atmospheric water vapor and the ground vapor pressure, ground temperature and precipitation are studied. It shows that the annual amount of atmospheric water vapor is about 0.2~2.0cm over Tibet Plateau and 0.5~4.5cm in Yunan province.

The results show that the increasing weight of tungsten oxide nanopowders and the color of tungsten nanomaterials turns light yellow from dark blue and black by increasing oxygen partial pressure in blown gas; the decreasing weight of tungsten oxide nanopowders and the color of tungsten oxide nanopowders becomes dark blue by the plasma that compares row increase including the hydrogen.The tungsten oxide nanomrods was increasing with chamber pressures. Urged nanoparticles to have the clavate fusion phenomenon in the development process with increasing plasma currents, and increased the nanorods distribution quantity along with the generated time to be more, 12 minutes later presents all nanorods. This system to prepare a monoclinic crystal W18O49 nanorods successfully, each hourly output approximately is 0.33 gram, and monoclinic crystal WO3 tungsten oxide nanoparticles, each hourly output approximately is 5.77 grams, its growth mechanism is Vapor-Solid solidly the physiognomy explanation.
