基于超声CT成像的钢-混凝土组合结构界面损伤识别研究

Jianzhu Gangjiegou Jinzhan
针对传统超声检测方法难以准确识别钢-混凝土组合结构内部缺陷的难题，提出了基于超声Computed Tomography （CT） 成像的钢-混凝土组合结构界面剥离损伤量化方法。研发了具有电磁屏蔽功能的磁吸式新型超声换能器，利用Akaike Information Criterion （AIC） 算法提取透射波初至的方法。基于所建立的正演数值模型和反演分析，系统性研究了Back Projection Technique （BPT），Algebra Reconstruction Technique （ART）

注射复合ｒｈＢＭＰ－２骨水泥制作猕猴椎动脉型颈椎病模型

Zhongshan Daxue xuebao. Yixue kexue ban, 2016
【目的】 寻求一种安全、微创、可信的构建椎动脉型颈椎病动物模型的方法。【方法】 高频超声监测正常猕猴（６只，雌雄各半，年龄３．５ ～ ５．５岁，体质量４ ～ ６ ｋｇ）的椎动脉血流状况，在高频超声的引导下通过骨穿针在猕猴颈Ｃ５－６左侧椎动脉旁注射复合重组人骨形态发生蛋白－２ （ｒｈＢＭＰ－２ ）的磷酸钙骨水泥１．５ ｍＬ来制作椎动脉型颈椎病模型，并用高频超声监测造模后椎动脉收缩期峰值血流（ＶＳ） 、舒张期末峰值血流（ＶＤ）、阻力指数（ＲＩ）、血管内径（Ｄ ...

基于改进小波阈值—CEEMDAN的变压器局部放电超声波信号白噪声抑制方法

Gaoya dianqi
为了有效去除变压器局部放电超声信号中的白噪声干扰，提高后续局部放电模式识别及定位的准确性，提出了一种基于改进小波阈值和自适应噪声完全集合经验模态分解（complete ensemble empirical mode decomposition with adaptive noise，CEEMDAN）的变压器局部放电超声波信号去噪方法。首先，通过对放电信号进行CEEMDAN分解得到一系列由高频到低频的本征模函数IMF（intrinsic mode function）；然后，利用多尺度排列熵（multi ...
