比如traction一词，居然连gain traction的义项都不收。。。体量小得多的朗文6都收了

同等体量的，本人首选ODE3，收词量大、释义全面，连澳大利亚/新西兰的用法都收，还有用法说明，释义用语也相当平易，感觉比OALD还好用。9 A6 T, t7 d+ `1 }. I
更难得的是，百科类词条居然还插入一小段科普：

: Y6 ~" e+ `8 N5 `Visible light is electromagnetic radiation whose wavelength falls within the range to which the human retina responds, i.e. between about 390 nm (violet light) and 740 nm (red). White light consists of a roughly equal mixture of all visible wavelengths, which can be separated to yield the colours of the spectrum, as was first demonstrated conclusively by Newton. In the 20th century it became apparent that light consists of energy quanta called photons which behave partly like waves and partly like particles. The velocity of light in a vacuum is 299,792 km per second

The first small mammals evolved from reptiles about 200 million years ago, and the group diversified rapidly after the extinction of the dinosaurs to become the dominant form of land animal, with around 4,000 living species. Mammals belong to the class Mammalia, which contains the subclass Prototheria (monotremes) and the infraclasses Metatheria (marsupials) and Eutheria (placental mammals such as rodents, cats, whales, bats, and humans)
