This paper studies measuring technique of glass - fiber three - dimension braided composite materials perform used by others , specially graduate student chai chun qian " production 由此，本文提出了一种基于电涡流传感器进行碳纤维三维编织复合材料预制件厚度测量的研究方法。
Determination of shear strength of welded joints of reinforcement mats or cages for prefabricated components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure 高压充气混凝土或敞开结构轻型聚集混凝土预制件用加筋毡或框架的焊缝剪切强度测定
Determination of shear strength of welded joints of reinforcement mats or cages for prefabricated components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure 敞形结构高压蒸养加气混凝土或轻集料混凝土预制件用钢筋网或罩的焊缝剪切强度测定
It is based on measuring carbon - fiber three - dimension braided composite materials perform , and provides accurately data for analyzing composite materials " mechanics 同时，这也为碳纤维三维编织复合材料预制件的在线测量奠定了坚实的基础，并且为复合材料的力学性能分析提供了准确的数据。
A fortran code was developed based on the models , and it can be used to simulate both infiltration of resin into a textile perform and cure of the resin saturated perform 本文用fortran语言编写了rfi工艺过程的模拟程序，该程序可以用来模拟树脂对纤维预制件的浸渍过程和浸渍充模完成后整个构件的固化过程。
Except the foundation columns , the viaduct will be constructed by pre - casting method and the pre - cast elements will be assembled by launching girders in a way similar to the construction of hung hom bypass 高架桥除了柱趸的地基部分，全部采用预制件装嵌而成，方法与建造红?绕道类似，都是以架空形式建造。
So it is closer concerned . it has important relation between composite materials " mechanics and perform thickness and irregularity index , but so far the perform thickness is only measured by hand 然而，编织物复合后的力学性能与编织物预制件的厚度及其不匀有着重要的关系，但是目前预制件的厚度还只能依靠手工检测。
Used to component joint water - proof , building distortion seam , construction seam and metal , concrete etc seam water - proof , for example , tunnel , substructure etc underground seam water - proof construction 适用于装配式结构构件砌接缝防水，建筑物变形缝、施工缝用和金属、混凝土等各类预制件的接缝防水，例如：隧道、人防、基础工程等地下工程的接缝防水。
This paper discusses the application of image processing and mathematical statistic on the braiding homogeneity measuring of braided composites material preform , in which expounds the hardware , software architectures and realizing methods as well 本文论述了用数字图像技术及数理统计知识对编织复合材料预制件表面图像进行编织均匀性检测的方法；详细阐述了检测系统的硬件结构、软件结构及其实现方法。
The feature model includes two characters : the braided unit ' s braiding distance and braiding angle . processing the climaxes information can get the two characters . this paper uses mathematical statistic technology to realize the braiding homogeneity measuring 最后采用数理统计中的变异系数这一统计量对预制件表面图像中的每个编织单元进行分析，分别对特征模型中的花节长度量和编织角量进行均匀性统计，进而完成复合材料预制件表面编织均匀性的测量。
