A general model of the transient behaviour of an oxygen probe is derived on more general assumptions than those previously considered. The present state of the art is shortly discussed in its relation to the newly derived equations: (1) the reducibility of the three-layer diffusional model to two-layer ones is discussed, and the two-layer model considering the membrane and the liquid film is verified experimentally, (2) experimental and theoretical treatments of transient probe characteristics determination are examined, and (3) the influence of chemical reactions of the first order as well as of zero order (microorganism respiration) in measured media on transient probe characteristics is quantified.
基于比之前所考虑的更为普遍的假设，推导了氧探头瞬态行为的通用模型。简要讨论了当前技术水平与新推导方程的关系：（1）讨论了三层扩散模型简化为两层模型的可约性，并通过实验验证了考虑膜和液膜的两层模型；（2）研究了瞬态探头特性测定的实验和理论处理方法；（3）量化了被测介质中一级以及零级化学反应（微生物呼吸）对瞬态探头特性的影响。
