On the other hand, edits can also be used to falsify information and give the erroneous impression that a process is under control ; for example, a program output edit may add a spurious " correction " factor to f values which fall outside of the pre - established limits, thus turning an unacceptable value into anue
另一方面，編輯可用來偽造信息，給人以錯誤的印象，認為工藝受控；例如，輸出編輯程序可以把偽造的「正確」因素加到確定的限制f值，然後將不可接受的數值轉變成可接受的。 -
