Abstract

The necessity to measure the longitudinal and transverse relaxation times T₁ and T₂ simultaneously for the purpose of controlling the state of a flowing liquid was substantiated if flow rate q can vary by two orders of magnitude. A novel method of determining T₁ was developed. A differential-type nuclear magnetic spectrometer was designed to employ this method, which allows measuring T₁ in the whole range of flow rate q. Experimental results are also reported.

用差分核磁谱仪测定流动液体的纵向弛豫时间

摘要

如果流量q可以变化两个数量级，则为了控制流动液体的状态，必须同时测量纵向和横向弛豫时间T ₁和T ₂。开发了一种确定T _1的新方法。设计了一种使用这种方法的差动式核磁谱仪，它可以在整个流量q范围内 测量T ₁。实验结果也有报道。
