The results showed that extremely cold rain and snow weather of Sichuan Basin was related well to the variations of water vapor、 frontogenetic function of Yangtze River Basin. at the mid-lower level of the troposphere, especially at 700 hPa level, there was water vapor convergence exiting lastly in Sichuan Basin for long time. And the time of convergence of water vapor was congruous with of cold air in Sichuan basin, and provided the water vapor conditions for the occurrence of low-temperature disaster.

结果表明：四川盆地的低温雨雪天气与南来的水汽变化及长江流域的锋生作用有密切关系，在对流层中低层700hPa上，四川盆地长时间存在稳定的水汽辐合区，水汽辐合的时段基本与盆地冷空气活动时间段一致，这为低温降水的发生提供了水汽条件。

The sound segments are grouped into consonants and vowels.there are several basic ways in which articulation can be accomplished:the articulators may close off the oral tract for an instant or a relatively long period;they may narrow the space considerably;or they may simply modify the shape of the tract by approaching each other.manners of articulation:stop,fricative,approximant,lateral.other consonantal articulations include TRILL,TAP or FLAP and AFFRICATE.consonants may be produced at practically any place between the lip and the vocal folds.eleven places of articulation are distinguished on the IPA chart.

音段可以分成辅音和元音两类。有这么几种发音的方法：发音器官暂时或相对长时间地关闭口腔通道；发音器官空间缩小；或者，发音器官互相贴近形成不同形状的通道。发音方法：塞音，擦音，通音，边音。其他的辅音发音方法包括颤音，触音或闪音，塞擦音。辅音几乎可以产生于唇和声带之间的任何部位，国际音标表区别了其中11个发音部位。发音部位：双唇音，唇齿音，齿音，齿龈音，后齿龈音，卷舌音，腭音，软腭音，小舌音，咽音，声门音。
