The compulsory evacuation of the city is under way after orders from Nagin on Saturday night. No vehicles are being allowed to drive into New Orleans.
纳金于周六晚间命令新奥尔良市民开始强制撤离。任何机动车不得驶入新奥尔良地区。
上述报道中，compulsory evacuation就是“强制撤离”，evacuation 就是leaving a place in an orderly fashion; especially for protection的意思，即“撤离，疏散”，“疏散、撤离的人”都叫做evacuee；而compulsory一般都用来表示“强制的，义务的”意思，比如compulsory education（义务教育），compulsory subject（必修课）等。
