The tone system is the pitch function with a single syllable,which can make a distinction between difference signification.The physical level performance of the tone is the functional relationship between the fundamental frequency and time.To distinguish Putonghua Tone2 from Tone3,directly by the characteristics of tone form was not always reliable.It is integrating pitch and duration two dimensions that can have a more accurate understanding of specific Putonghua tone.Phonetic experiments analysis showed that the tonal melody of the word by Putonghua Tone2 is bent downward,the RISING performance of Tone2 is not monotonic rise ,which is by its tone of concept.The author pointed out:there is a similarity between Putonghua Tone2 and Tone3,both tonal melodies are the first down then up curve.The difference between Tone2 and Tone3 is analyzed and compared from two aspects of pitch and duration.Then the author identified and verified some of the distinguishing features to recognize Tone2 or Tone3.Finally,the author had a try to generalize the nature of Putonghua Tone2 and Tone3:Tone2 is a kind of rising tone which is bent downward shortly and then uplifts rapidly ,Tone3 is a kind of low-lying tone which is made up of a long decline segment and a short rise segment.
