Under anaerobic conditions (where oxygen is absent) they metabolise the fuel by feeding off it and in doing so produce natural chemical reactions that produce a current.
在厌氧条件下(比如缺氧的地方)通过取食产生新诚代谢并以此引起化学反应产生电流。

But a study in the journal Current Biology suggests that feeding birds in winter can influence their course of evolution.
不过《当代生物学》杂志上的一项研究却表明，在冬季向鸟类投食可能会影响到它们的进化进程。

Longitudinal uniformity is decided to a great extent by weighting balance feeding fiber current and transverse uniformity is closely relating to air transverse distribution.
