The paper measures the agglomeration degree of China's twenty manufacturing industries in 1993, 1997, 2002 and 2003 by means of the index of industry concentration constructed by Ellision and Glaeser and concentration degree of the regions whose manufacture sales incomes rank the top five.
But under the increasing competition background of the medical industry, Tonghua medical industry begins to enter into the important period of transition in which the competing power of the market should be enhanced quickly. The conflicts that the degree of concentration of this industry is not high and the scale effect is unconspicuous appear step by step, and many enterprises for pharmacy fall across questions of lack in developmental stamina.
The nonselective, selective and double-selective spin-lattice relaxation rates of some protons in huperzine E were acquired in the absence and presence of AchE at a concentration ratio of [ligand]/[protein] = 1: 0.005.
When the initial concentration of indole was 150 mg/L, the concentration ratio of indole to pyridine was in the range of 1-10.
It is found that the character of aggregates and the degree of their influence depend on the PM-to-PEI concentration ratio, polymer structure, and reaction temperature.
It is shown that the vapor composition depends on the concentration ratio of sodium and boron oxides in the condensed phase.
It is shown that the basicity of melts increases with an increase in the Na2O content at a constant concentration ratio of glass-forming oxides.
A full characterization of the rheological properties of completely hydrolyzed milk as a function of two different parameters, i.e., the coagulator temperature and the concentration degree of the milk, is presented.
The begin of an interchange makes possible that the market has a greater level of competition, diminishing the concentration degree.
We take the concentration degree of firms in a certain sector as a reference point.
The decrease in the degree of concentration of heat flux with increasing depth is calculated.
Average concentrations of Ni(II) in suspended hydroxide and basic salts precipitated with NaOH from NiSO4 solutions and the degree of concentration of Ni(II) as functions of the initial concentration of Ni(II) salt in solution were studied.
The phenomenon of an "optical piston" was observed, indicating a high degree of concentration of atomic lithium vapor.
This method makes it possible to obtain a degree of concentration of copper ions in three cycles >amp;gt;300% higher than that attainable in the purely ion-exchange mode (without chemical reduction).
Using the apparatus, human sweat was analysed to show the degree of concentration possible with a natural sample and the variation in the chromatogram profiles of successive trapping from the same sample.
