  1. The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete

    研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優質粉煤灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉煤灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉煤灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。
  2. The results of the uni - factor experiments and perpendicular experiments show their best mechanic synthesizing craft as followed : nvp ( 10 % wt ), kh570 ( 20 % wt ), hema ( 70 % wt ), initiator ( 0. 2 % wt ), crosslinker ( 20 % wt ), reacting 20 hours under 80 c. the factors which influenced organic silicon modified pvp hydrogel soft contact lens material ' s swelling capabilities were researched, which included temperature, monomer content, ion concentration etc. the experiments showed the equation swelling content ewc improved with the increase of nw, droped with the increase of kh570 and ion concentration, improved then droped with the raise of temperature, and hydrogels got the least ewc at 45 c. experiment carried on todiscuss water dehydration mechanism of organic silicon modified pvp hydrogel soft contact lens materials, which showed dehydration process could be divided into evaporating stage and diffusing stage

    正交實驗結果表明， nvp ? hema ? kh570共聚物的機械性能最佳時，其合成工藝條件為： nvp用量10 （質量百分含量，下同） ， kh570用量20 ， hema用量70 ，引發劑aibn用量0 . 2 ，交聯劑nmba用量0 . 2 ，反應溫度為80 ，反應時間16h 。討論了單體配比、溶脹溫度、離子濃度等因素對有機硅改性pvp水凝膠軟接觸透鏡材料溶脹性能的影響。實驗得出：水凝膠材料的平衡溶脹度ewc隨單體nvp含量的增加而增大， ewc隨kh570用量的增加而減小，隨離子濃度的增大而略微降低，隨溶脹溫度的升高先稍微下降後有所提高， 45時平衡含水量最低。
  3. Through the comparison between freeze - drying and heat - drying, the agglomeration and the desorption of the precursor on carbon support can be alleviated with freeze - drying method. the effects on the electrocatalysts by pretreatments of carbon support, dispersant and precursor are studied. the result shows that pretreatment of the carbon support by kmno _ 4 can add oxygen - containing functional groups on the surface of carbon, which can reduce the hydrophobicity of the carbon support, and then make it much easier for carbon to dissolve in water to form suspension ; isopropyl alcohol can make the carbon support in high dispersion in the precursor solution, which can make the precursor absorbed on the surface of the carbon

    採用高錳酸鉀氧化預處理的碳載體比表面積較大，表面含氧官能團數量較多，親水性較好，有利於前軀體在碳載體表面的吸附;選取異丙醇作為預凍液中的分散劑，有利於碳載體在前軀體溶液中的分散，容易實現前軀體離子在碳載體表面的穩定吸附和分散;使用酸性pt （ no _ 2 ） _ 2 （ nh _ 3 ） _ 2作為前軀體，可以使前軀體離子和碳載體表面的酸性含氧官能團發生離子交換反應，使得前軀體離子吸附量增大，分散更加均勻，以上三種因素的選取都可以得到催化活性更高的pt / c催化劑。
  4. Using this system, we have studied matrine - inhibittory effect and trifluoperation - neuroprotection effect in hippocampal slices, also discussed the mechanism of long - term potentiation using anesthetic rats. the experiment results showed that matrine can inhibit the hyperactivity induced by penicillin sodium in dosage by changing the relative parameters of field potential ; trifluoperation can alter ps change with the time, enhance the degree and the ratio of ps recovery, then minis the hypoxic injury ; high frequency stimulate can increase ps amplitude and epsp slope for long time, buildup the in / out function of nerve cells, and enhance synaptic plasticity

    結果表明，苦參堿能夠劑量依賴性地抑制青霉素誘導的神經元順向信號傳導激活過程，使細胞外記錄到的場電位各個參數發生相應改變；三氟拉嗪可以改變ps的時相變化，提高ps的恢復程度和恢復率，減小了神經元因缺氧引起的不可逆損傷；高頻刺激（ highfrequencystimulate ， hfs ）可以長時間的增強ps的幅度和epsp的斜率，進而增強神經元的輸入輸出功能，增加了突觸的可塑性。
  5. To improve the plasticity to find the best contents of the sample through using several kinds of binder in different content, discuss the factors influence the shaping of extrude honeycomb. ( 3 ) how to improve the stability of big - surface - al2o3

    研究高氧化鋁含量的坯料的可塑性，採用不同種類及不同添加量粘結劑進行增塑實驗，探討影響擠出成型的因素。採用氧化鑭、氧化鋇的浸漿處理以改善基體上。
