The article introduces the factor of ownership change into Chinese production function model,utilizes panel data of Chinese 28 provinces in 1990 and 2001,to estimate and examine this model. The authors find that during the 10-year economic development,institutional change becomes a remarkable factor influencing Chinese economy.
Three methods of cluster analysis based on phenotype characters,heterosis,and RAPD's molecular markers,were compared in terms of methodology of heterosis grouping with 15 inbred lines used dominantly in commercial hybrid maize production in China.
This article describes the meaning, production method, main equipment and technicl & economical figures of plant construction of methanol protein production in China.
This article presents the significance of methanol prote in production in China, present major processes and equipment in the world as we ll as tech economical data for setting the production plant.
By means of the establishment of conglomerates by chemical fertilizer enterprises,agricultural institutes and agents,not only the sharing of software and hardware can be realized but also technological complementation can be accomplished,thus promoting the new fertilizers to play a greater role in agricultural production in China.
However, the future further concentration of China's production to the east caused by this shouldn't be the causes of our worry, and what should be worried about is that China's population won't be able to concentrate to the east correspondingly with the concentration of production to the east because of the restriction of institution, thus resulting in the further imbalance of production and population and more serious disparity of regional economy.
According to the mechanism in the forma-tion of double- markets and multi- markets systems, this article believes that the coexistence of double- mar-kets and multi- markets systems can basically affect and restrict China's production, distribution and con-sumption.
The genetic basis of heterosis in rice was studied in a cross between Zhenshan 97 and Minghui 63, the parents of the best hybrid widely used in rice production in China.
Based on the detection of heavy metal contents in soils in this study, it is initially concluded that the soils for dry fruit production in China are suitable for hazard-free growing.
Several exploratory experiments were carried out with a view to investigatethe rotary-cutting param ters which might affect the qualities of thick veneersfrom two common hardwood species, ash and basswood. Results revealed thatpossibilities for improving veneer qualities could be expected by regulating thepeeling variables.Rotary-cutting angle or clearance angle(a), compressibility th-rough nose-bar gap(△)and cutting temperature(t). were selected as The mainquality control factors during peeling Under vario...
In China, fish sauces are usually prepared from small marine fish of low marketvalue. In general, the raw materials are salted in the fishing boat, more than 30% ofsalt (by weight) being used. Therefore the period for fermentation in traditional proces-sing is very long. In this experiment we have tried to use low salt and high temperature processing.The salt was diluted with water to reach a concentration about 20.22 and 24°Be′. Thetemperatures of fermentation were set at 40--45℃ and 50--55℃. The results a...
