The application of additive manufacturing technology to the charge molding of energetic materials will subvert the traditional manufacturing concept of energetic materials, realize the advanced charge design concept, shorten the research and development time of weapons and equipment, and improve the comprehensive performance of weapons and equipment, which is of great significance for the rapid development of high-tech weapons and equipment. This paper analyzes the research progress of additive manufacturing technology in the field of energetic materials at home and abroad and puts forward some suggestions for future research of this technology. .展开更多

The incomes of traders and middlemen in different transaction mechanisms are compared on the base of static transaction models which are followed by the dynamic factor of technology progress. It can be found that the indirect trade is dominant in the circumstance where search cost is high. With the technology progress, the search cost trends to decrease. The increase in direct trade will have influence on the middlemen. But the middlemen will not disappear; its market power is dependent not only on the absolute level of the technology, but also on the comparative level of the technology adopted by the different transaction mechanisms.展开更多

It is necessary to test the effect of these efforts with quantitative method. To be exact, whether and how China's low-carbon technology innovation responds to climate change should be tested. Based on the2004-2015 panel data of 30 provinces in China, we use the method of ESDA analyzing the spatial correlation of China's low-carbon innovation technology. Furthermore, we use the spatial Durbin model empirically analyzing the spatial spillover effects. The results obtained are as follows: first,supply and demand of Chinese low-carbon innovation has some deviation in the spatial distribution. The low-carbon technology innovation as the supply factor shows the characteristics of expanding from the east to the west. Innovation in eastern China has always been the most active, but innovative activities in the middle and western China are gradually decreased.However, carbon emissions have the characteristics of moving westward, implying the change of technology demand different from technology supply. Second, China's low-carbon innovation actively responds to the trend of climate change, indicating China's technological efforts have paid off. However, the spatial spillover effects are not significant, showing that the efforts in each region of China still work for himself. Third, environmental regulation and market pull are important factors for low-carbon technology innovation. Among them, both supporting policy and inhibitory policy have significant impact on the local low-carbon technology innovation, but no significant spatial spillover effects. It shows that environmental policies in different regions are competitive and lack of demonstration effects. Economic growth and export as market pull have higher level of effect on low-carbon technology innovation for both local and adjacent areas.Some policy implications are proposed based on these results finally.展开更多

Some success and many setbacks in earthquake disaster mitigation consistently enrich our knowledge regarding the complexity of the conditions for earthquake occurrence and the process of earthquake preparation, promote the reconstruction and modernization of technical system for earthquake monitoring, and deepen the scientific research of earthquakes. During the last 5 years, the improvement and modernization of technical system for earthquake monitoring have clearly provided the technical support to study and practice of earthquake prediction and precaution, give prominence to key problems and broaden the field of scientific research of earthquakes. These have enabled us to get some new recognition of the conditions for earthquake occurrence and process of earthquake preparation, characteristics of seismic disaster, and mechanism for earthquake generation in China’s continent. The progress we have made not only encourages us to enhance the effectiveness of earthquake disaster mitigation, but also provides a basis for accelerating further development of earthquake science and technology in China in the new century, especially in the 10th five-year plan. Based on the history reviewed, the author sets forth a general requirement for development of earthquake science and technology in China and brings out 10 aspects to be stressed and strengthened at present and in the future. These are: upgrade and setup of the network of digitized seismic observation ; upgrade and setup of the network for observation of seismic precursors; setup of the network for observation of strong motion; setup of the laboratories for experiment on seismic regime; establishment of technical system for seismic information, emergency command and urgent rescue; research on short-term and imminent earthquake prediction; research on intermediate- and long-term earthquake prediction; research on attenuation of seismic ground motion, mechanism for seismic disaster, and control on seismic disaster; basic research fields related to seismology and geoscience. We expect that these efforts will significantly elevate the level of earthquake science and technology in China to the advanced international level, improve theories, techniques, and methods for earthquake precaution and prediction, and enhance the effectiveness of earthquake disaster mitigation.展开更多
