箱梁製造由鋼筋工程、模板工程、混凝土工程、預應力工程、移存梁工程、孔道壓漿工程、梁體封端工程、橋面防水層和保護層工程等施工環節組成。文中介紹的採用胎具製作和綁扎鋼筋，分底腹板和頂板分別綁扎並吊裝鋼筋骨架入模；拆裝式和液壓式兩種模板的設計、製作要求和使用方法；綜合考慮、優化混凝土配合比，混凝土灌注從兩端至中間、先底板、后腹板、再頂板的施工順序和斜向分段、腹板水平分層、附著式振搗為主、插入式搗固為輔的施工工藝，蒸汽養護的方法和規定；應力應變雙控制確保預應力施工質量的施工技術；採用重物移運器有效移梁的施工方法；壓漿、封端、橋面防水層和保護層施工的一些規定和注意事項等都是對箱梁製造行之有效的施工技術和施工方法，並可為以後類似施工作借鑒。Sow the seeds on the surface of organic fertilizer equality, sprinkle once, let the seed absorb water enough. put the cover of casing on the container, displace to the shade
將種子均勻地撒播於培養土表面，水澆灑一次，讓種子吸飽水份。將包裝封面蓋在容器上，移置蔭涼處。Optical fiber grating sensors have been widely applied to key civil engineering for its excellent apperceive and anti - wear ability, however, nowadays the package and actual engineering application of optical fiber grating sensors cannot be realized without the macromolecule glue, the aging ability of macromolecule glue restricts the wear capability of optical fiber grating sensor, using metal - package technique without glue for optical fiber grating sensors can resolve these questions mentioned above
光纖光柵傳感器由於其優異的感知和耐久性能在重大土木工程檢測中得到了廣泛的應用，然而目前光纖光柵傳感器封裝開發以及實際工程應用時基本離不開高分子膠粘劑，而高分子膠粘劑「短命」的蠕變、老化等性能嚴重地制約了光纖光柵傳感器耐久性能的發揮，採用無膠金屬化的方法對光纖光柵傳感器進行封裝，可以避免上述問題的發生。Catalytic converter is one of the main countermeasures in controlling the automotive exhaust emission in the world. most of the gasoline engine of car and light duty truck have been installed the catalytic converter in the u. s., japan and europe. from the review and analysis of a great number of foreign literatures, a set of evaluation technique and test method for reliability of automotive catalytic assembly has been set up
