摘要不合理的乾燥條件導致稻穀出現裂紋，破碎敏感度增大，碾米時整米率降低。 -
The preparation of optically active composite is a promising alternative to obtain a kind of new and competitive sensing membrane for fiber optic sensors, and has attracted the global attention. in this thesis, the modified sol - gel sensing membranes based on fluorescence quenching have been prepared by using tetraethoxysilane ( teos ) and dimthyldimethoxysilane ( dds ) as the main material, formamide as the drying control chemical additive ( dcca ), ru ( phen ) 3cl2 and ru ( bpy ) 3cl2 as the indicator. this kind of membranes is crack - free and has low indicator - leaking rate
本文以四乙氧基硅烷（ teos ） 、二甲基二乙氧基硅烷（ dds ）為主要原料，以甲酰胺為控制乾燥劑，二價釕離子絡合物釕（ ） ?聯吡啶（ ru （ bpy ） _ 3cl _ 2 ）和釕（ ） ?菲咯啉（ ru （ phen ） _ 3cl _ 2 ）為熒光指示劑，採用改進的溶膠凝膠技術，通過添加控制乾燥劑和有機摻雜兩種手段，制備了基於熒光猝滅原理的光纖氧敏感膜。 -
Next was an experimental study on modification of stone ballast concrete small hollow block. the influence of polypropylene fiber, expansion agent and both of them on permeability - resistance and both moisture expansion and dry shrinkage of the block were systematically tested. the testing results and theoretical analysis slowed that they all can improve its properties, among which polypropylene fiber can most effectively restrain it ’ s moisture expansion and drying shrinkage ; however, the block doubly blended with polypropylene fiber and expansion agent will be likely to most beneficially improve crack - resistance of wall filled with the block
試驗結果和理論分析表明，單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能改善混凝土空心砌塊的性能，其中，聚丙烯纖維更有利於限制單個砌塊的濕漲干縮，單摻聚丙烯纖維的空心砌塊濕脹干縮的波動性最小;雙摻聚丙烯纖維與膨脹劑對限制石渣砌塊濕脹干縮的效果不理想，但雙摻砌塊將更有利增強于砌塊填充墻的整體抗裂性。 -
The influence of polypropylene fiber, expansion agent and both of them on moisture expansion and dry shrinkage of the filled wall were systematically tested. the testing results and theoretical analysis slowed that polypropylene fiber was the most beneficial to restrain it ’ s moisture expansion and drying shrinkage, however, the block doubly blended with polypropylene fiber and expansion agent can most beneficially improve crack - resistance of wall filled with the stone ballast block, at the
試驗結果和理論分析證明上述試驗結果及理論分析，即單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能限制混凝土空心砌塊的濕漲干縮，其中，聚丙烯纖維的限制效果最好;但是，膨脹劑的補償收縮與聚丙烯纖維的限縮聯合作用使得雙摻砌塊更有利於增強混凝土空心砌塊填充墻的整體抗裂性能。 -
The author summarized the research results in this respect in recent years ; introduced the vitrifying conversion of rice and its influence on thermal physical property ; described the formation of crack and explained the formation of crack according to the theory of vitrifying conversion ; expounded the relationship between crack, breakage, percentage of head rice and vitrifying conversion ; finally put forward the suggestions to improve the existing rice drying technology and relevant problems to be studied further
介紹了稻穀的玻璃化轉變及其對熱物性的影響；論述了裂紋的形成以及根據玻璃化轉變理論對裂紋形成的解釋；闡述了裂紋、破碎、整米率、玻璃化轉變的相互關系；最後提出對現有稻穀乾燥工藝進行改進的建議以及有待進一步研究的問題。 -
The research in present years indicated that the vitrifying conversion could take place during rice drying, which resulted in great influence on crack and breakage of rice
近來的研究表明，玻璃化轉變可以在稻穀乾燥過程中發生，並對裂紋和破碎產生很大影響。
