纵向收缩 meaning in English
kick
longitudinal shrinkage
longitudinal shrinking
vertical contraction
Examples
- Test method for polyethylene jacket longitudal shrinkage
聚乙烯套管纵向收缩率的试验方法 - Longitudinal contraction deformation ： the component contracts in the weld direction after weiding
纵向收缩变形：构件焊后在焊缝方向上发生的收缩。 - Welding position : if the configuration collocation of weld is symmetry and the welding sequence is reasonable , the longitudinal contraction and transverse lateral contraction deformation are usually produced , incontrast , the bending deformation is usually produced
焊接位置：如果焊缝在结构布置对称，焊接顺序合理时，则主要产生纵向收缩和横向收缩变形，反之，则要发生弯曲变形。 - Taking the example in the three gorges hydroelectric station , we researched the influence of the weld process on the construction and operation of penstock after moving contract - elongate nodes , analyzed the deformation law of two plans and calculated the crosswise and lengthwise shrinkage in weld process using experience formula and theory respectively , and then analyzed the influence of the welding and installing process on shrinkage , finally chose the best installation plan
摘要以三峡水电站引水压力钢管施工现场为实例，研究取消伸缩节后焊接对引水压力钢管施工的影响，分析了两种方案在焊接过程中的变形规律，分别用经验公式和理论计算出两种方案焊接时的横向和纵向收缩量，然后分析收缩量对安装焊接过程的影响，选择出最佳安装方案。
