Abstract
A model for describing the motion of chemotactic bacteria in a capillary tube containing substrate is treated. Chemotactic substrate threshold effects are included in the chemotactic response coefficient. The ratio of the substrate threshold, ST, to the substrate level far ahead of the travelling band, S infinity, is used as a small parameter in developing an asymptotic solution of "near travelling wave" form.
摘要
研究了一种用于描述趋化细菌在含有底物的毛细管中运动的模型。趋化底物阈值效应包含在趋化反应系数中。底物阈值(ST)与行进带前方远处的底物水平(S)无穷大的比值，被用作一个小参数来推导“近行波”形式的渐近解。
