There are giant mineral deposits,including the Jinding Zn-Pb and Baiyangping Ag-Co-Cu,and other important mineral deposits(e.g.,Baiyangchang Ag-Cu,Jinman Cu deposits,etc.) in the Lanping Mesozoic-Cenozoic Basin,Yunnan Province,*** tabular ore-bodies and some veins hosted in terrestrial clastic rocks of the Mesozoic-Cenozoic age and no outcropping of igneous rocks in the giant deposits lead to the proposal of syngenetic origin,but the giant mineral deposits are not stratabound(***,sandstone- and Sedex-type).They formed in a continental red basin with intense crust *** mineralization is controlled by structures and lithology and occurs in different strata, and no sedimentary nature and no exhalative sediments are identified in the *** deposits show some relations with organic matter(now asphalt and petroleum) and evaporates(gypsum).The middle-low-temperature(mainly 110℃to 2.0℃) mineralization took place at a depth of about 0.9 km to 3.1 km during the early Himalayan(58 to 67 Ma).The salinity of ore-forming fluids is surprisingly low(1.6%to 18.0 wt%(NaCl)).Affected by the collision of the Indian and Eurasian plates,the mantle is disturbed under the Lanping *** large-scale mineralization is closely linked with the geodynamics of the crust movement,the mantle and mantle-flux upwelling and igneous *** mineral deposits and their geodynamic setting are unique in the Lanping Basin.

In view of not uniformity in conventional coprecipitation preparation, urea was used as the precursor of precipitator to prepare Cu/ZnO/Al2.3 catalysts for methanol synthesis. In the method, urea was dissolved in nitrate solution and hydrolyzed to produce OH- as precipitator after the solution was heated to 90℃. After 6h, the precipitation was accomplished. The evaluation results of the catalyst activity showed that this catalyst had comparable catalytic activities to the industrial catalyst, and reached its maximum activity at 2.0℃. At reaction conditions of 2.0℃, 3MPa,and SV=7600h-1, the STY of methanol was 0.38g/（mL·h） with syngas compositing of H2.CO, CO2. and N2.atmolar ratio of 65.9∶2..1∶2.9∶4.1. X-ray Diffraction （XRD） revealed that the particle size of CuO and ZnO was about 2.0nm, and Al existed in the form of ZnAl2.4 spinel in the catalysts.

[1]Global observations of electron density profile(EDP) from the COSMIC/FORMOSAT-3 satellites were used to investigate,for the first time,the additional stratification of the F2.layer over the equatorial ionosphere on a global scale,which is called F3 *** F3 layer in EDP was recognized through the altitude differential profile featured by two maxima existing from 2.0 km to the peak height of the electron *** were ,400 cases of F3 layer selected out of 48,000 occultation events at low and equatorial areas during the period of April 2.06-September *** results show that the highest occurrence of F3 layer appears at dip latitude 7-8°/ -7～-8°for Northern/Southern Hemisphere and is more pronounced during summer months at 10:00-14:00 LT. The occurrence also has a clear longitude dependence during boreal summer,with relatively higher occurrence at -80～-100°,-2.～2.°,80～12.°and -160～-170°longitudes, that is possibly associated with the wavenumber-3 diurnal tide(DE3).The results support the principle of the F3 layer proposed by Balan et al.(1998),which in turn validate the accuracy of the retrieval of the COSMIC EDP data.

＜正＞GLAD ZnS films prepared by electron beam evaporation method with glancing angle deposition technique are reported. The influence of different oblique angle on the structure and optical properties is investigated using atomic force microscopy and transmittance spectra. The GLAD ZnS films exhibit a porous structure with isolated island and columnar formed. The surface roughness increases with the increase of oblique angle. The refractive indexes of GLAD ZnS films are lower than that of corresponding bulk materials. The maximal birefringence is obtained at oblique angle α=80°, which is ascribed to the orientated growth and anistropic structure of GLAD films. Therefore, the glancing angle deposition technique is a promising technique to obtain enhanced birefringence property.

Grassland is not only one of the important ecosystems,but also is the basic vegetation for northern agro-grazing ecotone of *** the past decades,human activities have caused great land cover changes, such as desertification,grassland degradation,and *** and timely understanding of grassland is of critical importance for protecting northern agro-grazing ecotone's grassland *** fractal characteristic of grassland was analyzed using fractal theory in northern agro-grazing ecotone of *** significant conclusions are drawn as follow:(1) Spatial fractal characteristic is objectively exist in different steppe types or different elevation belt or grassland above some elevation;(2. The spatial structure of Temperate desert is the most complicated and the most unstable and that of Apline meadow is the simplest and the steadiest of all the steppe types.(3) In different elevation belt,spatial structure of High mountain grassland is the most complicated and the steadiest,and that of Middle plain is the simplest, and that of Low plain is the most unstable.(4) Spatial structure above some elevation is exist from complicated to simple and from steady to unstable when elevation is changing from high to *** above conclusions are very important for grassland administration and decision-making in northern agro-grazing ecotone of china.

＜正＞ The Altay orogenic belt, Xinjiang Uygur Autonomous Region in NW china, represents one of the important sites of juvenile crustal growth during the Phanerozoic time. However, some important issues, e.g., tectonic evolution and petrogenesis, still remain controversial. Two layers of the picritic rocks in the south margin of the Altay orogenic belt, were discovered in the lower part of marine volcanic-sedimentary
