【摘要】：文章結合國內外的研究,簡要敘述了反芻動物產生甲烷的機理、排放途徑,并著重綜述了國際上所使用的測定反芻動物甲烷產生量的各種技術,其中重點闡述了呼吸室技術、示蹤氣體技術、紅外光譜技術和微氣象學技術等。對于測定單個動物釋放的甲烷來說,呼吸室技術所測得的結果是最為精確的,但由于造價相對較高,限制了其大規(guī)模的應用;SF_6示蹤技術的應用較為廣泛;微氣象學技術所測得的結果經過校正后與呼吸室技術的測定結果接近;綜合考慮多種因素,紅外光譜技術因其檢測結果的精度較高且適用于多種條件,具有很大的發(fā)展?jié)摿��？傊?要根據(jù)測定的目的和實際條件等因素做出最合理的選擇。
[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.
