普通话韵母iou、uei、uen省写理由辩驳

Reasons for Omitting One of the Letters in Mandarin Rhymes IOU,UEI and UEN

普通话韵母iou、uei、uen的音变不是必然的,故三者的音变不能成为三者的省写形式在发音上的客观依据。当iou、uei、uen前面加声母时对三者实行省写不妥当,因为省写依据不足、以偏概全、有误导作用。DF理论不能说明三者可以省写。

It is unnecessary to change the pronunciation of Mandarin rhymes IOU,UEI and UEN in that these changes of pronunciation cannot be the basis for omitting one of the letters when we write them. When they emerge from the consonants behind,we should not omit one of the letters,because there are no sufficient reasons for doing so. Moreover,it is one-sided and misleading. DF theory does not mean we can change them arbitrarily.
