Aeration and reoxygenation is the significant source of the dissolved oxygen for spillway discharge. Due to the strong turbulence, large numbers of bubbles are entrained into the water, which causes the supersaturation of dissolved gas concentration and leads to bubble disease of fish. Firstly, the theory of the aeration and reoxygenation for spillway discharge is analyzed base on the mass transfer theory of water-air interface and the bubble interface. Secondly, the convection and diffusion equation of dissolved oxygen and the method of parameter selection are discussed. Finally, the progress and shortage of the present study are analyzed.

The Chinese Loess Plateau has experienced drastic human-induced land cover change in the last century. The Chinese government has planned a long-term project to restore the ecology and thus the environment. This effort requires the information of the ecological potential. This study presented a complete procedure for spatially modeling the potential vegetation index in arid Loess Plateau region. Spatially distributed wetness index was used to depict the environmental condition at each pixel. Enhanced Vegetation Index (EVI) of current steppe was obtained from Moderate Resolution Imaging Spectroradiometer (MODIS) data. A statistical relationship between the wetness index and the MODIS EVI were established. Based on the statistical relationship, potential EVI was estimated at each pixel. The results show that: (1) the potential EVI ranges from 0.15 to 0.25, (2) actual EVI of irriguous farmlands is obviously greater than the potential EVI of them, and (3) actual EVI of urban area is lower than the potential EVI of them. We believe that the modeled result can effectively facilitate the vegetation restoration planning for this area. In addition, the result may function as a base against which to estimate the historic changes in land cover and land use.

Water dispersible avermectin-layered double hydroxide nanocomposites were successfully prepared using sodium dodecyl sulfate as surface modifier. Concentrations of sodium dodecyl sulfate and NaCl had important effects on the product suspensibility, the highest value of which reached 97.6%. All the samples were characterized using zeta potential and contact angle measurements. Experimental results showed that the prepared nanocomposites could protect effectively the avermectin pesticide against UV light decomposition, suggesting the nanocomposites would be a promising candidate for water dispersible formulation, especially for photosensitive pesticides.

Based on land use and urban plan maps, we extraced urban land information of Chongqing urban area in periods of 1995,2000.2008. With the help of GIS softwares and statistical analysis model, such indexes as expansion speed, expansion intensity, expansion direction, expansion morphological, and landscape features were used. This paper analyzed the spatio-temporal characteristics of urban land expansion. The results are drawn as follows: (1) Since 1995, the expansion speed and expansion intensity of urban land accelerate obviously, but urban land expansion show significant disparities and spatial heterogeneity. (2) By topography and policy factors, Chongqing urban land expansion showed the northeast - southwest axial pattern. (3) Compact ratio of urban land is low, space form is irregular, and the heterogeneity is apparent. (4) During the urban land expansion, the trend of function centralization of land use become stronger.

The semi-solid slurry of AZ91D alloy, produced by a novel self-inoculation method, is isothermal treated. Microstructure evolution and mechanism of microstructure formation during isothermal holding are investigated. The results show that primary α-Mg grains are in small size and present polygon morphology in the slurry. During isothermal holding, the size of particles increases with increasing holding time, while the roundness turns better. But the excessive long holding time is bad for the size and roundness of particles. Deformation of dendrite arm is the primary cause of microstructure formation during pouring, meanwhile, ripening and coarsening during isothermal holding. The nucleus generated from the procedure of melt treatment by self-inoculation, and competitive nucleation in undercooled melt which is near the liquidus during isothermal holding is the main source of primary α-Mg phase.

In this paper, TM remote sensing images of 1988, 1992 and 2007 and ETM + remote sensing images of 2001 were used, together with topographic maps, DEM, land usage map, forest resource distribution map, ground investigation and other materials. A study on the dynamic change characteristics of bamboo resources in Shunchang, Fujian from 1988 to 2007 was developed and GIS extraction, superposition and analysis functions were used to analyze the dynamic spatial-temporal change characteristics of bamboo resources. The result shows that: the quantity of bamboo resources in Shunchang had prominently changed from 1988 to 2007. The area of the bamboo forest increased 16814.8 hm2, which was 1.59 times larger than before. The average annual area growth rate was 3.08%; more than 93% of the bamboo forest was located at an altitude below 800m, and 99.9% of the bamboo forest was located at an altitude below 1200m. The area of the bamboo forest decreases as the altitude increases. The dynamic change of bamboo forest area is subject to the influence of multiple aspects, including natural, social and economic factors. The rapid development of bamboo industry is the direct driving force for the expansion of bamboo resources.

The relative admittances of S2 versus M2, N2 versus M2, K2 versus S2, O1 versus K1, P1 versus K1 and Q1 versus O1 in the Bohai, Yellow and East China Seas are interpolated from harmonics at 113 long-term coastal and island tidal gauge stations. The empirical cotidal charts of N2, K2, P1 and Q1 are derived from the obtained relative admittance distribution and the cotidal charts of M2, S2, K1 and O1 obtained from satellite altimetry. Comparison with observed harmonics at 5 long-term tidal stations shows that the amplitude differences of these 4 constituents range from 0.3 to 1.9 cm, and the phase-lag differences range from 4 to 7°, except that the phase-lag differences become larger in the regions close to amphidromic points.

To use GAMIT software of GPS to separately calculate the multi-phase observation data of monitoring crustal deformation using GPS in a single-day can obtain high-precision baseline vector and its coordinated factor matrix of multi phases among different crust monitoring sites. Then we will establish a model of computing drift velocity of crust monitoring sites by using multi-phase baseline vector among different sites. To use GAMIT software for processing crustal deformation data monitored by GPS developed by VB language, combining with some GPS observation data from Crustal Movement Observation Network of China to conduct the corresponding adjustment calculation can obtain the vector diagram of sixteen sites' drift velocity of Crustal Movement Observation Network of China (CMONOC). The comparative analysis of the two models' results shows the accuracy and reliability of the data processing model proposed in the chart.
