Extinction ratio is ratio of logic "1" average optical power to logic "0" average optical power under the worst reflection and complete modulation condition.

消光比是指在最坏反射条件时，全调制条件下，逻辑“1”平均光功率与逻辑“0”平均光功率的比值。

Even so, and despite Mr Robinson's energy and pugilistic credentials, the contest is probably as much of a mismatch as that between Hartlepool and Mr Mandelson, whose campaigning skills, complete with the occasional modulation of accent, are as formidable locally as they have proved nationally.
