脹縮不均的 的英文怎麼說
中文拼音 [zhàngsuōbùjūnde]
脹縮不均的
英文
strangulated-
The thermal stress of ceramic regenerator resulting from its temperature difference and restricted extension and contraction has been calculated and analyzed, the result provides a theoretical basis for design and operation of high temperature air combustion system
對于由溫度分佈不均勻，陶瓷蓄熱體膨脹或收縮受限制而產生的熱應力進行了計算和分析，其結果為蓄熱式高風溫燃燒系統的設計及運行參數的選擇提供了理論依據。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。There is a material which we call invar. it is made of different metals. invar never expands or contracts much, and so it is useful in clocks
有一種我們稱之為不脹鋼的材料，它是由不同的金屬製成的，膨脹和收縮均很少。因此用在鐘里是很有用的。
