Within the blind Angle area of the Amalog Sonoscope leakage flux inspection system, the rotary rolling caused flaws in seamless steel pipes were missed quite often due to low detection sensitivity.
无缝钢管表面的斜轧缺陷，因位于漏磁纵横向检测机组的盲角区域，检测灵敏度低，容易漏检。
When the leakage flowrate is small, the pressure curve in frequency domain loses its sensitivity first then that in time domain loses its sensitivity.
当泄漏量较小时，压力曲线在频域先于时域失去其对不同泄漏位置的敏感性。
The experiment result showed that this technology can greatly improve the measuring sensitivity and detecting precision of leakage location on pipeline.
理论分析和试验结果表明，该测试技术可以有效地提高管道泄漏测试的灵敏度和定位精度。
