oxygen constant 中文意思是什麼
oxygen constant
解釋
氧含量-
We found that tio2 thin films are a amorphism when they are not annealed ; they are anatase when annealed at 300 c ; rutile occured be anneled at 700 ; ti02 thin films are transformed into rutile completely when be anneled at 1100. oxygen - sensing properties of tio2 thin films were analysised, and we found the variation law of sensitivity with the partial pressure of o2 and temperatures. sensitivity increases with po2 / ( po2 + pn2 ) at a constant temperature. the higher working temperature is, the slower sensitivity increasing with po2 / ( po2 + pn2 ) is
對tio _ 2薄膜氧敏器件特性進行了分析，發現靈敏度隨工作溫度和氧分壓變化的規律， 400以上時，在一定工作溫度下，隨氧分壓的增加，靈敏度逐漸升高；工作溫度越高，隨p _ （ o _ 2 ） （ p _ （ o _ 2 ） + p _ （ n _ 2 ） ）的增加，靈敏度增加越緩慢，在400下靈敏度隨氧分壓增加最快；在我們所測試的工作溫度點中， 400時具有最高的靈敏度，相對於他人的工作此溫度是比較低的。 -
A novel catalytic property of hemin is described. in ammonium buffer medium of ph 8. 08. 9, hemin has an ability to catalyze the decoloration of bromopyro - gallol red. oxygen dissolved in solution plays a role as an oxidant in the reaction. with sodium dodecylbenzenesulfonate and ethanol as effect - enhancing agents, the catalytic system obeys the michaelis - menten equation of enzymatic catalysis. the michaelis constant, catalytic constant and specificity constant of the system are estimated by lineweaver - burk plot to be 3. 710
在ph 8 . 08 . 9氨性緩沖介質中， hemin催化溶解氧氧化溴鄰苯三酚紅的褪色反應。在sdbs和30 %乙醇的增效作用下，催化體系服從michaelis - menten方程。用lineweaver - burk作圖法求得米氏常數催化常數和專一性常數分別為3 . 710 -
