Part two is about the analysis of theoretical basis for the social assistance legal institutions,which includes their department classification,their analysis of basic concept,their theoretical support and their analysis of value,and so on.The author holds that they regulate the redistributive economic relations requiring state intervenes appropriately and reflected by the actions of social assistance,they reflect and determine the implication and distribution of the redistributive economic relations,meanwhile they reflect and determine the distribution and direction of the benefits of social assistance intervened by state appropriately.Their appearance expresses the legal connection created for the poverty phenomena between state and the poor,so these legal institutions should be classified into the department of social distributive law in economic law which reflect the essence of economic law that state intervenes the economic relations required intervention appropriately.

第二部分是社会救助法律制度的理论基础分析，其中包括社会救助法律制度部门归属辨、社会救助法律制度的基本理念剖析、社会救助法律制度的理论支持以及社会救助法律制度的价值分析等内容，认为社会救助法律制度规制了由社会救助行为所反映出来的这种需要国家适度干预的再分配经济关系，反映并决定了这种再分配经济关系的牵连和分布，同时反映和决定了在国家适度干预下相关社会救助利益的分配和流向，其出现媒介了国家和贫困者之间因为贫困现象而生成的法律关系，这一法律制度归属于经济法部门中的社会分配法律制度子部门，明显地体现着经济法的本质属性——国家对需要干预的经济关系的适度干预。

Each cell was mapped by the center point on the cell of transverse section with extended up and down for four pixel (nine-pixel lengths in total) and two pixels in width, and thereafter line convoluted dot map was obtained.
