1. The cfst x - type arches improve the lateral stability by sloping the arc ribs , so it is ofen used in the designs of cfst arch bridge with small ratio of the width to the span . tongwamen bridge is a half - through cfst arch bridge , its span is 238m , and the width of its roadway is 10m , so the truss ribs in - plane is sloped into x - shapc to improve its lateral stability . as the cfst x - type arches with longest span all over the country presently , the design of tongwamen bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span
   钢管混凝土x型肋拱桥是一种利用拱肋侧倾来提高其横向整体稳定性的桥型，在宽跨比较小的钢管混凝土拱桥设计中应用较多。浙江铜瓦门大桥是一座中承式钢管混凝土无铰拱桥，跨径238m ，桥宽10m ，拱肋为平面桁架形式，所以采用了x型拱肋以提高其横向稳定性。作为国内目前跨径最大的钢管混凝土提篮拱桥，该桥的建成对我国今后长大跨径小宽跨比钢管混凝土拱桥采用提篮拱具有借鉴意义。
2. The software ansys6 . 0 is used to analysis the stability of the state after construction of tongwamen bridge , linear method is used in analyzing the finite element model of the bridge , the coeffient of stability of different state after construction is given . on the basis , the effect of different factors such as the arrangement of lateral brace , the sloping angle of arch ribs , the stiffness of bridge deck system , the effect of non - orientedly conservative loadings of the hanger and tie bar etc is discussed . the different coefficients of stability of changing these factors are given , so the factors that are vital to the lateral stability of x - type arches are found , and the rationality of the methods taken to enhance the lateral stability of tongwamen bridge is evaluated
   本文应用有限元分析商业软件ansys6 . 0 ，采用线弹性方法，通过对该桥的空间有限元模型进行稳定性分析，得出其成桥运营阶段各种工况下的稳定安全系数。在此基础上，本文还通过有限元模型分析，就拱的矢跨比、吊杆(立柱)的非保向力效应、桥面系的刚度、横撑布置形式、拱肋侧倾角等因素对该桥整体稳定性的影响展开探讨与研究。文中给出了各因素变化情况下的稳定安全系数，指出了对钢管混凝土提篮拱横向稳定性有显著影响的因素及其合理变化范围，并对铜瓦门大桥提高横向稳定性的措施的经济合理性进行了分析。
3. Our factory began to cooperate with some colleges , universities and research institutes in 1960s and has developed many varieties of molecular sieves including a - type , x - type , y - type , etc . , widely applied to air separation , metallurgy , insulating glass , integrated petrochemical industry , fertilizer and refrigerating industry
   我公司自六十年代中期起，与国内一批大专院校、科研单位共同努力合作，研制开发a型、 x型、 y型等系列分子筛品种，广泛用于空分、冶金、中空玻璃、大型石化、化肥以及制冷业。
