( tunnel 在 劍橋英語-中文（繁體）詞典 的翻譯 © Cambridge University Press) Modeling the kinetics of multistep tunneling processes is a straightforward problem that can be solved analytically without employing simplifying approximations. 來自 Cambridge English Corpus Superexchange models are better suited to the description of tunneling through inhomogeneous media. 來自 Cambridge English Corpus The passage of particles observed in the tunnels, now extremely reduced, of the vitelline envelope demonstrates that their interactions through the interface still exist. 來自 Cambridge English Corpus The percentage of stem tunnelled, internodes bored and cobs damaged did not significantly vary among treatments in the insecticide-treated plots (table 5). 來自 Cambridge English Corpus Termites tunnelled slowly in the dry sand, but diverted their tunnelling into the wet sand once it had been discovered. 來自 Cambridge English Corpus The areas selected for excavation, our research strategies, and our methodologies-especially for the tunneling operations-were planned with continual reference to these research objectives. 來自 Cambridge English Corpus
