The results indicate that with decreasing significantly the number and size grade of inclusions for the alloy refined with JDMJ flux, tensile strength and elongation increase; however, the yield strength is less than that of the alloy refined with MgO ceramic filter and unrefined alloy. With the decrease of the inclusions contents, the corrosion rate of the alloys quickly vary from 2.419 mg/（cm 2 ·d） to 1.265 mg/（cm 2 ·d）. After inclusion content is reduced to 0.385%, the corrosion rate has almost no changes. Finally, the relationship between the volume fraction of inclusions and service properties of GW103K alloy under different conditions are established quantitatively.展开更多

By the end of 2016, there were 231 million people over the age of 60 in China, accounting for 16.7% of the total population. About 150 million people aged 65 and over make up 10.8 percent of the total population. China is expected to enter the peak period of population aging by 2035. Therefore, the government as a single pension service main body management pattern already can not adapt to our country entered the aging society, mobilize and fostering social organizations to participate in the pension services is to build perfect endowment service system, satisfy people pension service demand model of a kind of indispensable. In view of the development of social organizations has just started in our country, there exist many problems and difficulties, so this article USES the ISM method, for social organizations to participate in research and analyze influence factors of pension services, and then find out the social organization in the process of participation in pension service problems, put forward effective solutions.展开更多

Based on the comparison research, the processes were optimized, such as steelmaking, heat treatment and multiple forging processes. The quality of Baosteel mandrels was greatly improved by increasing the homogenizing of an annealing temperature and refining processes. The results of the pilot trial showed that the average number of piercing steel tubes for Baosteel mandrels was over 3000 ,which reached the level of imported mandrels.展开更多

Based on the economic attributes of public goods and personal belongings, this paper divides the old-age service into the old-age service of private property and the properties of public goods （pure public goods and quasi-public goods） according to the family status, economic status and health status of the clients. This paper explores the theoretical basis of price decision mechanism and effective supply of these two kinds of old-age services, and finally puts forward the concrete measures of the reform of the old-age service price in the light of the actual situation of the current pension service in our country.展开更多

The results show ： the t8/5 , t8/3 and inner wall peak temperature Tp decrease with the cooling rate increases. The welding energy is carried off by flowing medium, the cooling rate increases, and many unbalanced microstructures such as granular bainite, martensite and M-A generate ; it worsens the properties of HAZ. Under air-cooling, the cooling rate is slow, the austenite grain grows obviously, the lath ferrite crosses the whole austenite, and it causes the hardness value is also big. The change of HAZ width is not obvious with the increase of cooling rate; and burn-through is not susceptible to the cooling rate. The quench microstructures increase and the hydrogen does not outflow from the HAZ easily when increase the cooling rate, so the susceptibility of hydrogen cracking increases.展开更多

It is the inevitable choice for the development of Chinese characteristics for the aged. At present, with the continuous development of the combination of medical care and rehabilitation, the process of combination of medical care and breeding is slow, and the problems of inter departmental cooperation, high cost of resource integration and low service efficiency have emerged. The paper puts forward that multi head management of different responsibility management body is a bottleneck problem that hinders the integration of medical care. From the objective and subjective two points of view, the administrative system level barrier and the inter departmental interest game are the important reasons that obstruct the medical support and break through the estrangement of the Department and realize the cooperation. Then, according to the theory of large part system reform, the author boldly proposes the idea of establishing a new comprehensive functional department that specializes in the management of pension related affairs.展开更多
