The polar regions are rich in resources with high scientific value.Polar scientific research is of great significance to natural environment,climate,astronomy and geology.Polar scientific research is closely related to polar energy supply.Most research stations still use fossil fuels as the main source of power generation.This kind of power supply not only pollutes the environment,but also consumes a lot of manpower and material resources.As a kind of renewable energy such as solar energy and wind energy,renewable energy not only has the characteristics of sustainable development,but also has the characteristics of local power generation and transportation cost saving.At present,several countries have started the construction and application of polar renewable energy,and achieved good results in some Antarctic stations.Based on the investigation and summary of the application of renewable energy in various countries,this paper discusses the development trend of polar energy supply in the future,and provides a clear idea and direction for the development of polar renewable energy. 展开更多

采用高功率半导体激光作为焊接热源,在连续模式和调制模式下对316奥氏体不锈钢进行堆焊试验,分析了调制模式下占空比和调制频率对焊缝成型的影响规律,并与等效热输入连续模式下焊接的焊缝成型和硬度进行对比和分析。结果表明,在调制模式... 采用高功率半导体激光作为焊接热源,在连续模式和调制模式下对316奥氏体不锈钢进行堆焊试验,分析了调制模式下占空比和调制频率对焊缝成型的影响规律,并与等效热输入连续模式下焊接的焊缝成型和硬度进行对比和分析。结果表明,在调制模式下,随着占空比增大,焊接熔宽、熔深均呈增加趋势;当占空比>50%时,焊接模式开始从热导焊转变为深熔焊;占空比越大,频率对熔宽、熔深影响越小。显微硬度测试结果显示,调制模式的热影响区要小于连续模式,采用调制模式能够减小焊缝的热影响区,从而减小焊接变形。 展开更多

To construct the rule of law, we can not only rely on the legal system itself but also should we take good use of the legal person' s active participation in the building process, which would be the driving force. Only the static legal system itself can not nile out the presence of ruling of man and something like unjust privilege. However, legal person's dynamic involving in the conslluction of rule of law, by means of legal person's constraints to the person of rule of man, can effectively protect citizens' legitimate rights and interests, by what we can achieve the maximum degree of eliminating social injustice as well. There is no doubt that the lawyer is just the Sllong force that above-mentioned who promotes the process of legal construction to develop better and longer. 展开更多
