Colditz was supposed to be escape proof, but these incorrigibles kept escaping (one via what may have been the world's first hang glider), although few made it to Switzerland. When I visited Colditz in 1987 with Reid and two American officers, the place had been turned into an anti-Nazi museum.

科尔迪兹公认是最难逃跑之战俘营，尽管没谁成功逃到瑞士，但这些逃心不死者还是试图逃跑（其中一个逃跑方法应属世界上第一架悬吊式滑翔机）。1987年，里德、两位美军军官和我一起参观科尔迪兹，那地方已变成反纳粹展览馆。

In order to overcome the shortage of conformable precision, polyamide affinity membrane modified by cibacron blue F3GA was introduced into the pretreatment unit to get rid of interferer from large molecule such as albumin in serum. The affinity membrane was combined with micro-fluidic chip by embedded and external methods and using external-combination pretreatment unit, average enrichment was 89.36 times, RSD was 4.37%.
