| | A new type of laser holographic vacuum stressing nondestructive testing instrument has been developed by the authors. The instrument can be used for testing comparatively large sized samples with most of its optical elements contained inside its airtight cabin. In this paper, the testing results of debond flaws for solid fuel propellant grains are given.The virtues and defects of thermal stressing and vacuum stressing are discussed. | | 本文介绍一种大型内光路真空加载激光全息无损检测仪用于固体火箭发动机药柱包复层界面脱粘缺陷检测的情况和结果,并且对热加载、真空减压加载等两种加载方式的优缺点进行了讨论。 | | 文摘来源 | | BZJ-3 Surface Wave instrument is a new detector developed based on the theory of surface wave, electromagnetic, electronics, and micro computer techniques. It is designed to non-destructively detect dam construction quality rapidly. In construction of Shisanlin concrete face rock--fill dam and Puding rolled concretedam, the data by using this instrument are more of less the same as the data obtained by means of samplingtests and by using density probes. | | BZJ-3型表面波施工质量快速无损检测仪是根据表面波理论,应用电磁、电子、微计算机技术研制成功的用于筑坝施工质量现场无损检测的新型仪器。经十三陵蓄能电站上池面板堆石坝和普定碾压混凝土拱坝现场测试,其结果与同期挖坑取样和核子密度仪测试结果十分相近,证明该仪器测试数据可靠,精度较高,可满足工程质量监测的要求。 | | 文摘来源 | | According to cardiograph, this paper designs a new harmness heart-function detector-heart function spectrometer. The spectrometer's principle is based on digital signal processing and modern spectrum analysis technology. It has higher sensitivity, faster detecting speed and higher degree of accuracy of diagnosing. This is a specific application of microcomputer automatic detection and diagnosis in medical science. | | 本文根据心音频谱图设计了一种新的心功能无损检测仪──心功能频谱仪。此仪器之原理建立在数字信号处理技术及现代频谱分析技术的基础之上,是微机自动检测与诊断技术在医学上的具体应用。 | | 文摘来源 | |   | | << 更多相关文摘 |
