摘要
The aim of designing sentences with special tone combinations is to investigate the declination tendency of intonation in Chinese Putonghua.The result shows that baselines of prosodic phrases（PP）,as the basic declination units,show the phenomena of declination clearly,and the declination slope is in inverse proportion to the length of PP.Different tone combinations of PP have different declination slopes.The primary conclusions are as follows： （1） If low points are at the beginning of prosodic word（PW）,the absolute value of baseline slope is larger than those at the end;（2） The declination of PP is larger,if it is at the beginning of sentences than that at the end;（3） When there are several PPs in sentences,although in different syntactic relations the degree of declination is different,they have the common ground of PP declination.
