The basic the- ory indicates that any fuze safety system is a physical system comprising finite safety ele- ments each of which can independently affect the system's states, and the arming process is a dynamic one in which the extent of safety of the system changes only gradually. The theory and method can be used to analyse the arming process and to guide the development of fuze safety systems.展开更多

This mixed system, called voluntary continuation in the obligatory system, contemplates the option for workers who have concluded a work relationship and who wish to continue accumulating weekly contributions necessary to obtain the disability and life insurance rights, such as those of dismissal in old age, and are considered in the Social Security Act of 1973.展开更多

Workers who transfer into the flexible employment from regular employment easily lost the original endowment insurance rights and interests, which increase the cost of laborer to flexible employment and impede the development of flexible employment. The establishment of the endowment insurance system of flexible employment can eliminate the apprehension of supporting themselves and enjoy in old age well.展开更多

The outstanding reflections are that attaching less importance to social insurance system, too high insurance fee and not perfect security system and other phenomena. This paper focuses on the empirical study and analysis of this type of problems, in order to put forward the feasible solution of social insurance for migrant workers. The migrant workers generally refer to the labor workers of household registration as farmers working in towns for non-agricultural occupation. At present, China＇ s migrant workers has exceeded 2.6 billion, and this group has been long in the city and rural edge, difficult to get the social insurance policy. According to the National Bureau statistics data, the migrant workers of not buying industrial injury insurance, endowment insurance, medical insurance and unemployment insurance are respectively 67.64%, 73.37%, 73.77% and 84.65%. In order to guarantee the interests of vulnerable groups in the marginalized position, the social insurance problems of migrant workers have become the our focus.展开更多
