MODIS has the advantages of multi-band, high spatial and temporal resolution, which are propitious to the dynamic monitoring of a large area of arid regions. During late October 2008 and mid-February 2009, more than 10 provinces in east-central and northern China were hit by the severe drought. In this paper, Liaoning Province suffered the serious drought in early 2009 is selected as the study domain. The drought information in MODIS data is extracted through the thermal inertia model, which is used to distinguish the range and the degree of the drought. In order to make a deep analysis of atmospheric structure characteristics and mechanism which led to this drought, wind direction, wind velocity, temperature, humidity and structure characteristics of atmosphere energy during this drought are revealed from two aspects: weather situation, Skew-T diagram. The results show the main reason for this drought is the abnormal atmospheric structure, including the maintenance of dry cold air path caused by the strong and stable northeast cold vortex, the large temperature-dew point difference of the whole troposphere, the little water vapor in source area because of the northwest wind and the stable distribution of atmosphere.

The content of total flavonoids in peanut hulls was determined by the extraction technology of cellulose and ethanol using efficiently peanut hulls as raw materials in this paper. The extract was purified by AB-8 macroporous resin. The structure of the product had been characterized with UV- spectrum and IR- spectrum. The results showed that: the enzyme amount was 0.8%, the temperature was 40¿, the pH value was 5.0, the ethanol concentration was 70%, under these conditions, the total flavonoids content from peanut hulls was 4.86%. Using this extraction method, it proved that the purified product was luteolin by structural anlysis.

To establish a method for determination of lead in lipstick with microwave digestion and FAAS. Microwave digestion of samples with selected digestion conditions and FAAS were used to determine Pb in 10 lipstick samples. In the system of nitric acid (7.5 ml) and hydrogen peroxide (1.5ml), the time of microwave digestion was 10 minutes; a better result of digestion was obtained. The linear range and the detection limit of this method was 0.003 mg/l and 0.9994 respectively. The recovery rates of this method were 94.6%¿102.5%. This method is satisfied for determination of lead in lipstick samples.

Application investigation on polyureas anticorrosion in flue of Wet Flue Gas Desulphurization Equipment (FGD) (product model: DTTW-¿ -150) was carried out according to corrosive environment and technical parameters of a coal-fired power plan. And relevant design requirements were confirmed. The results showed that Polyureas can be used to anticorrosion in flue desulphurization equipment because of their wear and high temperature physical properties. When the construction conditions was thickness of 3.0 mm, the high-temperature polyureas protective coating smooth appearance, adhesion 7 MPa, at 150 ¿ environment polyureas still had outstanding performance. The useful life of 20-year anticorrosion coating was preliminary estimated based on the corrosion margin.

Ecological building is a key factor in sustainable development. Compared with contemporary building, the vernacular building has ecological and environment-friendly strategies which could contribute to modern building design. In this paper, Tibet is studied as a case and the main ecological aspects of Tibetan vernacular building such as natural resource, solar energy use and climate response are discussed. And it is concluded that the key of vernacular building in Tibet is the harmony attitude to the environment, and the passive and sustainable solutions should be redeveloped for modern application in building design.

Wavelet analysis has become an active research field for over twenty years. In this work, we develop the concept of a class of biorthogonal vector-valued multivariate wavelet packets associated with a pair of biorthogonal scaling function vector. A new method for constructing biorthogonal multivariate vector wavelet packets is formulated. Their characteristics are researched by means of operator theory, time frequency analysis method and matrix theory. Three orthogonality formulas regarding the wavelet packets are provided. Birthogonality decomposition relation formulas of the space L2(Rr)3 are obtained by constructing a series of subspaces of the vector-valued wavelet packets. Furthermore, several wavelet packet bases of space L2(Rr)3 are constructed from the wavelet packets

Information Systems have begun to turn simplicity to complexity, and to turn hard-to-use to easy-to-use. However, effectiveness and efficiency on information systems is not satisfying. The paper mainly analyzes information systems problems from an ecological perspective to make people scientifically and comprehensively understand information systems and seek for better solutions to development and use of information systems. Computer software ecology is the most complex among the four ecologies (computer software ecology, computer hardware ecology, computer talents ecology and information surroundings ecology which information systems ecology involves), and has bigger effect on information systems ecology and information ecology than the other three. Computer software ecology will be also mainly discussed.
