    結合課題組以往的研究成果，根據試驗橋設計使用壽命100年的要求，確定出高耐久性混凝土的設計控制指標，基於最緊密堆積原理和最佳漿骨比原理對橋梁的墩柱、蓋梁、預制箱梁和橋面板用高耐久性混凝土的配合比進行設計，並對其施工應用技術進行了研究。
  4. The effect of deposited condition, include substrate temperatures, different substrates and annealing on the structural properties of zno films has been studied in considerable detail. it is found that the optimal conditions to deposit zno are below : the substrate temperature of 450c, the substrate of sapphire. the sample on this condition is 0. 3491

    通過分析襯底溫度、不同襯底和退火對樣品結構的影響，得到了樣品的最佳制備條件：襯底溫度450 、藍寶石襯底，此條件下制備的樣品具有高度（ 002 ）取向性， （ 002 ）衍射峰半高寬僅僅0 . 3491 ，原子力顯微鏡（ afm ）分析表明zno薄膜具有密集堆積的均勻柱狀晶粒。
  5. Changing the grading of sic particles not only affects the strength and pile density, but also modifies the phase compositions and microstructure of the material. with the reducing of sic particles, the strength of the material increases obviously. the nitrification scheme has the greatest influence on phase compositions and microstructure " of si3n4 ( si2on2 ) - sic, after two continuous nitrification reacting peak and short - time high - temperature treating, the best properties can be obtained ; and the residual strength of the composite is much higher after the thermal shock resistance test, which shows that the material possesses excellent thermal shock resistance

    本論文較全面地探討促進強度和顯微結構良好的si _ 3n _ 4 （ si _ 2on _ 2 ）結合相的實驗條件，實驗數據顯示：引入適量的燒結助劑能夠促進si _ 3n _ 4 （ si _ 2on _ 2 ）的生成和晶粒的長大，而過量時，其促進作用反而下降；隨著si粉加入量增加，生成的結合相明顯增多，復合材料的性能顯著提高；改變sic顆粒級配不僅影響復合材料的強度與堆積密度，而且對復合材料的物相與顯微結構也有影響，隨著顆粒逐漸細化，材料的強度有較大的提高；對復合材料的強度、物相與顯微結構影響最大的是氮化制度，經過兩個氮化高峰連續的反應和短時間的高溫后處理得到的復合材料性能最好；通過抗熱震性能實驗后復合材料的殘余強度較高，顯示出較好的抗熱震性能。
