摘要：
Now the wood multi-layer floor industry in China is not relating to ecological environment construction for severe pollution, low utilization rate of raw materials, high energy consumption and low products extra value. Therefore, the development countermeasure is urgent to be studied in order to help the wood multi-layer floor industry in China placidly pass through the crisis. Based on survey reports and large numbers of literature and data about wood multi-layer floor, the developing present situation of wood multi-layer floor industries in China were in detail summarized. On this basis, the ecological management mode of finishing technology of wood multi-layer floor in China were proposed to promote healthy development of wood multi-layer floor industry.

摘要：
Retard-bonded post prestressed concrete is a new distinctive prestressed type. It absorbs the good parts and abandons unfavorable parts of un-bonded and bonded in traditional post prestressed concrete. Based on a large number of orthogonal tests and theoretical analyses, a kind of super-retarding mortar which meets the requirements of retard-bonded prestressed concrete is prepared and used for the retard-bonded post prestressed concrete system. The prestressed camber, as well as strain variations of concrete and prestress losses of retard-bonded post prestressed concrete beams were studied through the experiment of 4 beams. The experimental results were compared with the theoretical results, by which the principle and law of prestress losses of retard-bonded post prestressed concrete beams were obtained. It provides the reference for the actual project application of the new retard-bonded prestressed concrete system.
