摘　　要：膜式溶氧电极作为测量溶液中含氧量的一种重要测量工具,但因其电化学性质受到局限而需要搅拌,针对人工搅拌的不足,提出了将提高测量稳定性的一种由于BOD5动测量的新型溶氧电极搅拌装置,装置采用离心式机械搅拌。通过实验验证,该种搅拌方式有助于稳定测量出培养瓶内溶液的溶氧量。The membrane dissolved oxygen electrode is an important tool for measuring oxygen content in solution,but there is limitation because of its chemical properties as the dissolved oxygen electrode measurement of oxygen consumption usually requires artificial stirring. A new dissolved oxygen electrode stirring device using BOD5 automatic measurement is put forward to increase the stability by using the centrifugal type mechanical stirring. Experiments show that the proposed stirring device offers stable measurement of the dissolved oxygen content in the culture bottle.
