- 英文摘要:
Theoretica1 and experimental studies are performed for the tubing method
which is an accurate and reliable method to measure the dissolved oxyged in fermenta-
tion. Medical grade silicon rubber tubing (I. D. 0.2cm., O. D. 0.3cm.) and Beckman
Oxygen Analyzer Model F-3 are used for these experiments. Calibration 1ines for
the cases of many combinations of agitation speed and aeration ratio are prepared
using city water as liquid. Experimental results show that simplified Equation (17-a),
(pAr√Pa)=1-exp(-Αk0), which is derived by theoretical analysis, is a good correlation
for the reading of oxygen analyzer and oxygen tension in liquid. - 中文關鍵字: --
