查询词典 beam-focusing

The experimental results show that: the failure mode of strengthened beam at elevated temperature can be classified as flexure failure mode or flexure-shear failure mode, and the failure mode of strengthened beam at high temperature may be different from that at room temperature; and although the load supported by the strengthened specimen is larger than that supported by the unstrengthened specimen, the fire resistance of the strengthened specimen is still larger than that of the unstrengthened specimen, due to the influence of fire insulation.

结果表明：高温下该类构件的破坏形态大致可分为受弯破坏和弯剪破坏两类，常温下发生弯曲破坏的加固构件有可能在高温下出现破坏形态的转变；虽然加固构件所承受的荷载明显大于未加固构件，前者由于防火涂料的保护，其耐火极限仍大于后者。

Based on the fire tests of one unstrengthened reinforced concrete beam and five reinforced concrete beams strengthened in flexure with carbon fiber sheets, the influence of fire insulation thickness, load ratio and strengthening ratio on the fire resistance of reinforced concrete beam strengthened in flexure with carbon fiber sheet has been discussed.

Based on the practice of first simple beam and later continous prestressed concrete combination box in the constructions of Xiangcao river bridge and Tanglong bridge, and analyzing the quality problems in the constructions, this paper puts forward some suggestions and mensures concerning plate making, steel fixing, Concrete pouring, box beam installation and system concerting, etc.

主要针对312国道镇江段香草河大桥和汤龙公路大桥采用先简支后结构连续部分预应力砼组合箱梁的施工中，在底板制作、钢筋绑扎、混凝土浇筑、预应力张拉、箱梁安装、组合体系转换等方面所采取的质量控制措施，本文分析对比了两座桥施工中好的做法及出现的质量缺陷，提出一些防治、处理措施及建议。

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.

诱发突变谱中碱基颠换比例是0.85，且是全部G：C→T：A颠换，推测低能离子束诱变鼠伤寒沙门氏菌得分子机制可能为：离子注入→通过破坏细胞表面进入内部→刺激产生大量自由基→自由基氧化损伤DNA→G变成8氧—7，8—二氢鸟嘌呤(8—oxoG)→8—oxoG与A配对→导致G：C→T：A颠换。
