A flow injection chemiluminescence (CL) method for the determination ofcatecholamines is described which is based on their inhibition of the intensity of CL from theluminol-hypochlorite system. The hypochlorite was electrogenerated on-line by a constant currentelectrolysis, resulting in the elimination of the instability of the hypochlorite solution preparedfrom a commercial reagent of sodium hypochlorite. The detection limits are 0.6 ng/ml fordopandne, 0.8 ng/ml for adrenaline and isoprenaline. The proposed method has been successfullyapplied to the determination of catecholamines in pharmaceutical injections.

有一天妈妈跟我说，你应该长大了。突然之间，我必须要长大了。 记得小时候妈妈常在被窝里给我讲故事。那时我刚写完作业，炉子里的炭火在微弱地喘息，弟弟妹妹在酣睡，只有妈妈在静静地陪我。作业写完后，等妈妈把被窝暖透了，我才试探着钻进来，没等躺平便迫不及待地把冰凉的小脚丫使劲往她腿上、脚上蹭，有时，妈妈会把它们顺势塞进衣服里，在肚子上摩擦。等到完全吸走了妈妈的温暖，我便缓过神来，眨巴着眼睛摸着她的脸“嗯”
