| 受安装空间、高温环境和复杂介质等限制，压力测量系统中往往需要引压管腔来传递压力，管腔成为限制系统频响的重要因素。首先回顾了管腔动态特性的理论研究进展，简述了国内外围绕管腔动态特性影响因素的研究成果。其次，介绍了现有的引压管腔主要校准方法，并分析了不同校准方法自身的特点和使用条件。最后，指出了现有校准方法在实际使用中的不足，并对进一步的研究做出展望。 |
| 英文摘要: |
| Pipeline or cavity always exist before the pressure transducer when measuring pressure because of limitation of installation space, high temperature or complex media. The pressure measurement systems’ dynamic characteristics are often determined by the pipelines. The theoretical research progress of the pipeline dynamic characteristic is first reviewed, and the research results of factors affecting the dynamic characteristic are presented. Then the main calibration methods of pipeline are introduced, and the characteristics and using conditions of different calibration methods are analyzed. The existing problems and the further study needed in the future are finally discussed. |
