adj.不送气的；不吐气
Objective To explore the spectro-mode features of unaspirated consonants of Chinese Putonghua produced by healthy, normal children and children with cleft palate.───目的：初步掌握健康儿童和腭裂术前患者汉语普通话语音中不送气辅音的声学特征。
The results of experimental study show that Chinese unaspirated and aspirated consonants as two phonemic categories can be established in JPL's perception and production.───结果表明，日本学习者能够在感知和发音中建立汉语不送气音和送气音两个音位范畴。 但学习者不能在发音中准确地产生汉语送气音。
the voiceless consonants are aspirated, strong and long. the voiced consonants are unaspirated, weak and short.───清辅音送气，强，长。浊辅音不送气，弱，短。
Second, the GAP of the unaspirated bilabial plosives is longest.───二是不送气双唇塞音的闭塞段时长最长。
