  1. The compatibility and harmony among workability, mechanical grade and durability are optimized, with the ground of adjusting composition and dosage of fd - 1 ; after analyzing anti - freezing damage mechanism, it is concluded that temperature is main factor, which affects structure and property of concrete. after two processes of temperature - elevation of hydration heat and temperature - descent of cold - environment, there is original damage in concrete and its existence leads to temperature fields, as results in temperature damage on transition phase > aggregate and cement mortar of concrete

    通過對負溫混凝土早期防凍分析研究認為，環境溫度對混凝土的結構形成及其性能的影響十分突出，水泥水化溫升和環境散熱降溫兩個過程導致混凝土結構內部產生不均勻溫度場，對過渡相、水泥砂漿以及骨料都能產生不同程度的溫度損傷，產生內部溫差應力裂紋，初始損傷也是不可避免的。
  2. Through systematically analyzing the composition and structure of concrete from three levels of macroscopic, microcosmic and ultra - microcosmic, the author of this paper found that the mechanical properties and durability of concrete depended on mainly its composition and structure. the interface, which is one of three composition of concrete ( hardened cement paste, aggregate and interface ), is the most weak zone in concrete

    作者通過對混凝土材料的組成和結構進行宏觀、微觀和細觀三個層次的系統分析發現，混凝土材料的力學性能和耐久性主要取決于其微觀的組織構成；在組成混凝土材料的三相（硬化水泥漿體、集料和硬化水泥漿體-集料界面過渡區）中，界面過渡區是其中最薄弱的一環。
  3. On the basis of analyzing factor ( soil particle composition, soil bulk density, water stable aggregate content, antecedent soil moisture, slope gradient, rain intensity, accumulation depth and soil crust, soil and water conservation tillage measures ) affecting soil infiltration rates, several relation models was obtained ; analyzed in detail different soil and water conservation tillage measures intensifying infiltration rates, while there have the same rainfall condition, the increasing infiltration rates of contour tillage and artificial digging and artificial hoeing in gully areas of loess plateau are 67 % and 41 % and 29 % ; the increasing infiltration rates in hilly areas of loess plateau is 45 % and 22 % and 14 %

    在相同的降雨條件下，黃土高原溝壑區等高耕作與直線坡相比，可提高入滲67 ，人工掏挖可提高入滲41 ，人工鋤耕可提高入滲29 ；黃土丘陵溝壑區等高耕作可提高入滲45 ，人工掏挖可提高入滲22 ，人工鋤耕可提高入滲14 。並根據黃土高原超滲產流的概念和水量平衡方程，建立了不同水土保持耕作措施強化入滲速率模型。
  4. Based on the basic principles of densified systems containing homogeneously arranged ultra - fine particles ( dsp ) and reactive powder concrete ( rpc ) adopted by foreign researchers specialized in building materials, silica rume, ultra - fine fly ash, quartz powder, 52. 5 - class portland cement and superplasticizer were selected and mixed, the theoretic of mixed steel fiber reinforced cement - based composite materials and of micro - aggregate filling voids were applied, the composition was adjusted, the mixture ratio of rpc was optimized, a suitable curing schedule was adopted, in the result, an ultra - high performance concrete designated rpc was successfully prepared by normal technology methods

    本文基於超細粒聚密材料（ dsp ）和活性粉末混凝土（ rpc ）配製的基本原理，選用硅灰、粉煤灰、石英粉和硅酸鹽水泥，輔以高效減水劑，採用多重復合的技術路線，運用混雜鋼纖維增強理論和微集料填充密實原理，調整材料組成，優化混凝土配合比，結合適宜的養護制度，在現有技術條件下，成功制備出了rpc200材料。
  5. Abstract : through a study on soil aggregate composition, nutrient status and enzymatic activity under mixed forest of chinese fir alniphyllum fortunei and pure stand of chinese fir, the results indicated that, compared to pure stand, the soil structural property was ameliorated, the soil capacity of nutrient supplying and was improved, and the soil enzymatic activity were enhanced

    文摘:通過對杉木擬赤楊混交林及杉木純林土壤團聚體結構、土壤養分狀況及酶活性的研究表明，與杉木純林相比，混交林土壤結構性能得到改善，供肥和保肥能力加強，各種土壤酶活性提高，土壤肥力較好。
