Structural studies of catalyst indicated that the cystalline Na_3WO_4 and Mn_2O_3 in the catalyst disappeared after 300 h reaction, the structure of α-cristobalite in the fresh catalyst was transformed to the structure of α-tridymite and α-SiO_2. However, the yield and selectivity of C_2 products were not affected by the structural changes.
Currently, the study of this theory centers mainly on the following difficulties and deficiencies: its measurement, its investment and accumulation, its structural changes as well as its connections with property ownership.
Abstract This paper analyses the structural changes of economic growth and rural reform in Guangdong province in four aspects: the rural industrial structure, the agricultural structure labor and land utilization structure.
The second chapter describes the present condition of chines high education and structural changes and summarizes the present condition and main problem of classifies and reservation in Chinese regular university.
Following the Historical Marxism, this thesis analyzes the economic development and structural changes of TengChow Fu in the Late Qing by economic and positive method, in order to find out the economic position and the main character of this district after Chefoo becoming a opening commercial port.
Metastable structure and structural changes of Cu-Ag, Cu-Al, Ag-Al, Cu-Ag-Al alloy films prepared by co-evaporation, onto cooled substrates have been, investigated systematically, and some unique phenomena are exhibited in the amorphous formation and crystallization.
We select GroE from E. coli with two ligands naming GroEL and GroES to analyze. Based upon the crystal structural data from PDB, The relation of structure and function of GroEL apical domain combined with GroES and target protein or not, is studied, as well as the influence of the structural changes of GroEL on the accessibility and the hydrophobicity of its central cavity.
Methods of the Sequential Testing of Hypotheses in Problems of Analysis of Random Processes Involving Structural Changes
A Model of Optimal Control of Structural Changes in an Organizational System
An optimal control of structural changes in a finite time interval involves the choice of the sequence of structural transformations that maximize the total profit.
In experimental ecosystems that accommodate perch fry (Perca fluviatilis), significant structural changes within the benthic communities occurred under the effect of fish feeding on oligochaetes and on the larvae of chidonomids and other insects.
