  1. In this paper, the so preparing self - compacting concrete with low and middle strength using super fine mountain sand artifical sand and phosphorus slag is studied systemically. through the study the influence of the shape, the proportion of the dust and the grade of sand to the workability and the mechanical property of self - compacting concrete, it is found that super fine mountain sand artifical sand are not suit to prepare low and middle strength self - compacting concrete, but when they are combined and the additive and assistant band material are used, c20 - c40 high performance self - compacting concrete is prepared ; the corresponding additive is developed to solve the delamination caused by the low proportion of banding material ; the evaluating system for the workability of low and middle strength self - compacting concrete is built ; the controlling method for production, construction and curing was set up. and the result of the research is applied into several projects

    通過分析特細山砂和機制砂的顆粒形態、粉末含量、顆粒級配等特性對自密實混凝土的工作性能和力學性能的影響，發現特細山砂、機制砂不宜單獨用於配製中低強度等級自密實混凝土，宜將特細山砂和機制砂進行合理復配，並選擇合適的外加劑和礦物摻合料，優化配合比設計，可生產c20 c40中低強度等級自密實高性能混凝土；研製開發出了具有高效減水、保塑、抗離析功能的外加劑，有效解決了中低強度等級自密實混凝土由於膠凝材料用量少而出現的離析、泌水問題；應用正交設計方法，對因素和水平進行合理選擇，確定了生產中低等級自密實混凝土的最優配合比；建立了中低強度等級自密實混凝土的工作性評價體系；提出了生產、施工及養護的質量控制技術方法。
  2. Surplus environmental capacities of din and po4 - p were positive and remained constantly, relative to 1st grade environmental capacities, from late 1970s to mid 1980s, but it decreased sharply from mid 1980s to late 1990s

    膠州灣din和po _ 4 - p剩餘環境容量在20世紀70年代末至80年代中期變化較小，相對國家一級海水水質標準下的環境容量還具有約60的容納能力。
  3. The value of surplus environmental capacity of din exceeded about 70 percent of the 1st grade environmental capacity in 1997. since 1997, the impact of nutrients pollution has begun to mitigate because of the enhancing protection of marine ecology by local government. the variation of surplus environmental capacities of din and po4 - p in jiaozhou bay implicated that the discharge amounts of din and po4 - p to jiaozhou bay were bearable from late 1970s to mid 1980s

    但自80年代中期至90年代中後期，營養鹽剩餘環境容量迅速減小，至1997年din剩餘環境容量已超過國家一級海水水質標準下膠州灣din環境容量約70 ，而自90年代末開始膠州灣din剩餘環境容量又有所增加，而po _ 4 - p剩餘環境容量減小速度趨緩。
