The simulative model of temperature field and stress field in concrete , Heat and moisture coupling、Parallel simulative calculation of concrete with water pipe cooling、 Parallel feedback analysis of thermal characteristic parameters, and stress intensity factor of induced joint, which are the sixty-four-dollar questions, are studied in this dissertation. The main contents of this dissertation are as follows:(1)Based on the past and current research work, the calculation theory of the transient temperature field and creep stress field of mass concrete which self temperature influence is considered is deduced. The couple effect between the temperature field and humidity field of concrete, is considered on the basis of conservation law of water and energy, and the coupled formulation which coefficient is not constant of the heat and moisture in concrete is deduced. The calculation theory and model which is theoretically strict for solution to thermal problem in concrete with water-cooling pipes are recommended.

Data for the study were collected by field survey and collection of second-hand material.The main conclusions of the study include: 1 the transfer of collective forest land and stumpage will determine to what extent the aims of the current institutional reform will be achieved; 2 at present the transfer is highly affected by the transfer institution, while the requirement of transaction in the market is not suited to farmers; 3 farmers earn money from the transfer, while they do not benefit reasonably from the transfer; 4 farmers'economic activities are not completely rational, and their economic behaviors are affected by cognitive degree on the institution, non-agricultural production activities, investment in forestry, and family status; 5 there are large variations among those who take over different forest lands and stumpages, however they all try to maximize their owns profits; and 6 policy regulation plays negative influence on the development of transaction market.

本研究结论如下：第一，集体林地林木流转的开展情况对于集体林权制度改革目标实现的影响重大；第二，集体林地林木流转现状反映了现行流转制度安排；第三，农户通过流转得以增收，但流转收益并不完全具有合理性；第四，农户转出林地林木行为受制度认知程度、非农生产活动、林业生产投入和家庭状况等多层面因素影响；第五，受制度约束影响，受让方流转行呈现差异性；第六，政策规制的存在，影响了流转市场发育。
