摘要：
On the basis of using RegCM regional climate models and with the data of 10km horizontal resolution to perform numerical simulation in subtropical region of China for 20 years, the author makes a conclusion that: Compared with the global model, regional model provides a more detailed temperature and precipitation in the spatial distribution of information. There exists an apparent performance of the phenomenon of "Warm Nest" in the southern part of both Hunan and Jiangxi in the simulation process, reproducing the basic features of the climate of those regions.

摘要：
In order to evaluate its potential health risk to human settlements, the volatiles of Pinus massoniana biomass which was used indoor, were adsorbed and determined by TD-GC-MS. And the main constituents of volatiles at 40 degrees C were 1,4-methanoazulene,decahydro-4,8,8-trimethyl-9-methylene-(53.09%), bicyclo[2.2.1]heptan-2-one, 1,7,7- trimethyl-(11.4%), cyclooctasiloxane, hexadecamethyl-(9.28%), octasiloxane, 1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(5.09%), 1,3-benzodioxole, 5-(2-propenyl)- (3.19%), p-menth-1-en-8-ol(2.93%), tricyclo[5.4.0.0 (2,8)] \undec-9-ene, 2,6,6,9-tetramethyl-(2.43%), eucalyptol(2.03%), etc. The main constituents of volatiles at 60 degrees C were 1,4-methanoazulene,decahydro-4,8, 8-trimethyl-9-methylene-(43.43%), bicyclo[2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)- (7.34%), 1,6,10-dodecatriene, 7,11-dimethyl-3-methylene-(6.63%), 1,4-methanoazulen-9-ol,decahydro-1,5,5,8a-tetramethyl-(5.9%), octasiloxane, 1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(4.24%), 1r-.alpha.-pinene(4.1%), etc. So the Pinus massoniana biomass was safe under 60 degrees C.

摘要：
A study of the modified diatomite prepared by the PAM coated on the surface of the raw diatomite and applied to treat the simulated wastewater with intensive concentration of lead ions [Pb(Ⅱ)]. Pb(Ⅱ) has been considered as one of some significantly toxic heavymetals (Cd,Cr,Pb, Mn,Cu,Zn,et al) contaminated the surfacewaters. The results indicated that modification could enhance the diatomite and acidic heavymetal wastewater’s compatibility; Obtained that modified diatomite’s saturated adsorption capacity could reach 66.15~ 68.95mg/g, superior to raw one; At the same time, the comparation of four common adsorbents and modified diatomite’s adsorption capacity under some given conditions showed: modified diatomite > zeolite > vermiculite > raw diatomite > red soil; Observed by SEM, PAM molecule arrayed on the diatomite’s surface smoothly that improved its interior structure and the charge on the surface, even enhanced the sedimentation performance of the diatomite in heavymetal wastewater.
摘要：
Nowadays, QQ Instant Message has become one of the most popular and widely used forms of electronic instant communication way. The social interactions or contacts patterns between people by QQ Instant Message can be analysis using social network mode. Tracking the user' data activities is always known as significant source of information, allowing the Network Managements to be aware of the activities that the user carried through, along with their outputs. At the same time, it can be considered a privileged element, exploited by the researchers and the developers to improve the communication environments. In this paper, we present the latest results of our research works, regarding the approach adopted for efficiently tracking the QQ user's activities.

摘要：
Land use and cover changes lead to the changes of land surface structure and exert a big influence en the supply of land ecosystem service by changing the structure and function of the ecological system. With the collaboration of the Arc GIS software, the diagram of LUCC pattern in Changde City is vectorized. On the basis of Geostatistics, the nature and effect of the spatial differences of the ecosystem service value are analyzed. Accordingly, the study is of great significance to in-depth discussion on the comprehensive effects of the land use changes and reducing damages of economic constructions on the ecological environment by utilizing the land in a rational way. The results indicate: (1) the per unit area service and function value of the various land ecosystems in Changde City is revised and measured in accordance with the benchmark unit price of China's land ecosystem and ecological service proposed by Xie Gaodi and the methodology by Peng Jian and other experts. (2) there is a spatial correlation among the service and function indicators of the land ecosystem. Kriging Interpolation Model can describe and analyze the spatial distribution pattern and accurately reflect the nature of the regional spatial differences. (3) Geostatistics is applied so as to simulate the spatial consecutive distribution pattern of the regional variations. The characteristics of regional variations have been taken into consideration. Hence, the nature of spatial variations of ecological service and function service can be analyzed and reflected. (4) the differences of ecological service and function value cannot justify the rationality of the land use in Changde City. However, such changes reflect the impact of the land use changes on the land ecological service value, which can help readjust the land structure and utilize the land in a rational way. The appropriate model of ecological service use reasonably takes into account balancing the relationship between the land exploitation and use, the social and economical development, and the ecological and environmental improvement. The reasonable using land gives impetus to the region's interactive and coordinate development in order to achieve the maximization of social, economic and ecological effects.

摘要：
GPS then started a new era of navigation. Even though the system is very sophisticated the user does not have to be an expert to use it. The devices have become so small that they can be carried around without any difficulty to any place. So it can be seen as a tool that introduced accurate navigation to the masses. Its success can also be measured by the fact that other nations are also implementing similar systems. The combined use of GPS and these systems will lead to better availability and more precise positioning. Also the scheduled launches of new satellites will increase the accuracy of GPS by adding additional, technically even more elaborated, satellites to current constellation. Certainly the development of GPS remains of interest in the future.
