发布时间：2019-06-09 16:26
【摘要】：文章结合国内外的研究,简要叙述了反刍动物产生甲烷的机理、排放途径,并着重综述了国际上所使用的测定反刍动物甲烷产生量的各种技术,其中重点阐述了呼吸室技术、示踪气体技术、红外光谱技术和微气象学技术等。对于测定单个动物释放的甲烷来说,呼吸室技术所测得的结果是最为精确的,但由于造价相对较高,限制了其大规模的应用;SF_6示踪技术的应用较为广泛;微气象学技术所测得的结果经过校正后与呼吸室技术的测定结果接近;综合考虑多种因素,红外光谱技术因其检测结果的精度较高且适用于多种条件,具有很大的发展潜力。总之,要根据测定的目的和实际条件等因素做出最合理的选择。
[Abstract]:Based on the research at home and abroad, this paper briefly describes the mechanism and emission path of methane production in ruminants, and focuses on the various techniques used in the world to determine methane production in ruminants, with emphasis on respiratory chamber technology. Tracer gas technology, infrared spectroscopy and micrometeorology. For the determination of methane released by a single animal, the results measured by respiratory chamber technology are the most accurate, but because of the relatively high cost, its large-scale application is limited, and the application of SF_6 tracer technology is more extensive. The results measured by micrometeorology are close to those measured by respiratory chamber technique after correction. Considering many factors, infrared spectroscopy has great potential for development because of its high accuracy and applicability to various conditions. In a word, the most reasonable choice should be made according to the purpose and actual conditions of the determination.
