中文摘要：

反刍动物甲烷排放监测一直难以建立起精确的评估体系,其中一个重要原因是常用检测反刍动物甲烷排放的方法不够完善,另外检测仪器受外部环境的影响,难以保证其准确度和灵敏度。目前,红外光谱检测技术正在被广泛应用于反刍动物甲烷排放检测,一些基于红外光谱检测技术的最新检测方法,如甲烷激光检测（LMD）、傅里叶变换红外光谱检测（FTIR）、Green Feed（GF）系统和便携式自动开路气体量化系统（GQS）也得到广泛运用。与以往常用方法相比,红外光谱检测技术具有一定优势。本文根据现有文献,从红外光谱检测的原理、可靠性及与其他常见方法对比,论述了红外光谱检测方法在反刍动物甲烷排放中的应用现状和应用前景,旨在为精确检测反刍动物的甲烷排放提供参考。

英文摘要：

So far an accuracy system for detecting methane emission of ruminants has not been established,because the common measurements need more improvements,and the detector is easily affected by some environmental factors,thus hard to guarantee its sensitivity and accuracy.Infrared spectroscopy techniques have been largely applied in detecting methane emission of ruminants,and some newtechniques based on Infrared spectroscopy,such as laser methane detector（LM D）,Fourier transform infrared spectroscopy detector（FTIR）,Green Feed（GF） system and portable auto-open circuit gas quantification system（GQS）,are also widely used.Compared with common measurements,infrared spectroscopy techniques have convinces in monitoring enteric methane emission.This paper,based on the existing references,summarized the research status and prospect applications of infrared spectroscopy in detecting methane emission of ruminants,and aimed to provide further references for precisely monitor methane emission of ruminants.
