摘　　要：试验仪器为BODTrakTMⅡ型压差式BOD测定仪,选用不同浓度的标准水样,对仪器的准确度和精密度进行试验研究;选用河道、水库天然地表水水样,进行压差式BOD测定仪与稀释与接种法的比对试验。试验结果表明,压差式BOD测定仪具有较好的准确度和精密度,在地表水的检测试验中,相对于传统的稀释与接种法,体现出较好的结果准确性和操作优越性。The test instrument is BODTrak TM II BOD tester. The accuracy and precision of the instrument are tested by using standard samples of different concentrations. The comparison test between differential pressure BOD measuring instrument and dilution&inoculation method is carried out with natural surface water samples of rivers and reservoirs. The test results show that the differential pressure BOD measuring instrument has good accuracy and precision. Compared with the traditional dilution&inoculation method, it shows good result accuracy and operation superiority in surface water test.
