UV Tri was observed photometrically from 1999 to 2000 at the Xinglong Station of the National Astronomical Observatories, Chinese Academy of Sciences,and was al
The optimum Mo/[H+] ratio per unit cell of the active precursors in Mo/HZSM-5 catalystsfor methane dehydro-aromatization, measured by 1H MAS NMR, was found to b
We have calculated the sulphur 1s near edge X-roy absorption fine structure (NEX-AFS) spectra of SO2 adsorbed on Pd( 111 ) in terms of the multiple-scattering C
Fault recognition and coal seam thickness forecast are important problems in mineral resource prediction. Knowledge of multiple disciplines, which include minin
Reactions between CH4 and CO2 under the action of continuous microwave discharge atatmospheric pressure were studied in a special homemade reactor. The main pro
We make a statistical study of the energy sources of high-velocity phenomena, Herbig-Haro (HH) objects. IRAS counterparts of HH objects are identified.Their col
Water yield and sediment yield in the Teba catchment, Spain, were simulated using SWRRB (Simulator for Water Resources in Rural Basins) model. The model is comp
An experiment was performed to determine the dietary phosphorus requirement of the young abalone, Haliotis discus hannai. Five semi-purified diets were formulat
The purpose of this paper is to discuss the influential factors of iteration accuracy when we use iteration to determine the numerical model for predicting wate
