简介:本教(也作“苯教”)是西藏地区土生的宗教,受本教影响的藏区文化观念区别于藏传佛教文化和汉文化,《尘埃落定》中蕴含着西藏本教的观念,主要表现在世界观、女性崇拜和生死轮回观念上。本教观念的蕴含,带给作品独特的审美特征,象征性地表达了藏族文化中人们对宇宙人生的理解,以及作者的宗教与人文关怀。
简介:摘要: 超声波无损探伤( NDI ),是超声无损检测技术的一种发展与应用,具有穿透能力强、设备简单、使用条件和安全性好、检测范围广等根本性的优点,加上压电复合材料、数字信息化处理技术和计算机模拟等高新技术的应用,检测设备由最初的模拟机,到现在应用最广的智能数字机,再到超声检测新宠相控阵设备,检测技术不断提高,工件内部缺陷的呈现形式越来越清晰、直观、精准。本文通过基础的 A 型脉冲波形显示检测原理,分析焊缝内部缺陷的超声检测技术要点。
