Continuously Enhancing Resources Utilization Ratio and the Production Technology Level of Cleaner Fuel so as to Realize Sustainable and Rapid Development
The main results are following:(1) Net emergy output ratio and emergy input ratio of cropping system in Jilin province are both higher,they are 2.03 and 6.18.This shows that production technology level is high while its environmental pressure is severe.
The analyzing results show that it will bring new opportunity for the development of Medium Diameter welded pipes afte r adjusting the production structure of welded pipes and improving the production technology level of Medium Diameter welded pipe.
Based on integrating the effects of yield potential from irradiation and temperature,average yield level of last three years,soil fertility,fertilization and water management levels and production technology level on yield increment,the dynamic yield increment index was quantified and a rapeseed knowledge model for design of target yield under different temporal and spatial environments was developed through knowledge engineering and system modeling method.
The production technology level and product practicality quality level of domestic elevator wire rope enterprises are introduced. It is pointed out that the current production development situation of domestic wire rope for elevator and product development orientation are to develop forging rope,double strength rope and compound structure wire rope for elevator.
The progress of polybutadiene rubber production process are introduced. The production consumption and market prospect of polybutadiene rubber at home and abroad are analysed. Suggestions for the development of polybutadi- ene rubber in China are put forward,including improvement of production technology,exploiture of new production and trademark,enlargement of export as well as enhancement of application and development.
Only by improving the level of productive technology, reducing energy consumption, improving the efficiency of energy utilization, it is possible to realize economic sustainable growth in long under the condition of guaranteeing sustainable utilization of energy.
Now, China is undergoing a transitional period from a planned economy system to a market economy system, with the economy growth sliding down and economic conflicts in-depth getting increasingly sharp in that the level of productive technology lags behind, scientific and technological content in products is low, added value is low, and market competitiveness is of great lack. .
In the fourth chapter, the enterprise’s internal resources, product’s combination, the level of productive technology, personnel resource management and organizing structure are analyzed.
Only by improving the level of productive technology,reducing energy consumption,improving the efficiency of energy utilization,it is possible to realize economic sustainable growth in long under the condition of guaranteeing sustainable utilization of energy.
Based upon the material from academic exchanges in group discussions at the Interna- tional Meeting on Petroleum Engineering in Beijing, March 19~22, 1982, this article summarizes the recent foreign developments and production techniques on dewaxing and paraffin inhibition in oil wells and oil delivery lines, injection water quality and pro- duced water treatment, oilfield automation, separation, measurement etc., and sets forth ideas on how to improve them in accordance with China situation.
This article stresses on the discussion of the rock drillability in diamond drilling. It is generally agreed that the drilling rate, not the true but the apparent rock drilladility and should not be used as a standard for rock drillahility classification. Drilling rate is effected by the state-of-the-art and the intrinsic attributes of the rocks drilled. The intrinsic attributes of rocks, out of our control, may be represented by a quantitative index (or the drillability value) and expressed as the exponent...
