四则运算教学视频:AS PER REJECTED PART TARGET IN AFTER SUPPLY TO OEM.中文？

AS PER REJECTED PART TARGET IN AFTER SUPPLY TO OEM.中文？ AS PER ATTACHMENT是什么意思？ delivery proceeds as per contract As low as $3.95 per SF 翻译：freight payable as per charter party Marked "freight payable as per charter party". 法律术语 "payable as per" 是什么意思？ forwarding: as per your instructions and at your cost是什么意思？ I don't use as wide a vocabulary as in the prepared part. 法律标准中的as per 作何解释，具体用法怎样？
