中文摘要：

与特殊音调联合设计句子的目的是在中国 Putonghua 调查语调的偏斜趋势。作为基本偏斜单位，诗体学的短语(PP ) 的基线清楚地看偏斜的现象的结果表演，和偏斜倾斜在到 PP 的长度的反的比例。PP 的不同音调联合有不同偏斜斜坡。主要结论如下:(1 ) 如果低点在诗体学的词(PW ) 的开始，基线斜坡的绝对值比在结束的那些大；(2 ) PP 的偏斜更大，如果它在结束比那在句子的开始；(3 ) 当在句子有几 PP 时，尽管在不同语法关系偏斜的度是不同的，他们有 PP 偏斜的共同点。

英文摘要：

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.
