摘要

在简述分布式光纤传感技术测温原理的基础上，从三维微元体传热过程出发，推导了具有渗漏和内热源的多孔介质传热微分方程，给出了基于温度测量的分布式光纤渗漏监测技术的不同监测方法的监测方程。最后，从持续线热源的角度，阐述了分布式光纤监测渗漏的基本原理

Abstract

The principles of distributed fiber optic temperature sensing technology are described briefty. From heat-transfer process of micro-body

a heat-transfer differential equation of porous medium with seepage and internal heat source is deduced. The monitoring equations of different monitoring methods are given. Based on persistent line heat-source

the basic principle of distributed fiber optic sensing technology for leakage monitoring is expounded.
