本文报道闽东福清方言中一项降调新发现:短降也分高低两类。降调原来分六型十种,现在发现有七型十一种。七型是从调长、调高、调拱来定义的。五个长降:高降、低降、微降、高弯降、低凸降;两个短降:短高降、短低降。这七种调型全都出现于中域。其中四型还出现于低域:弛声高长凸降(弯降变体)、弛声低短凸降、弛声低降、嘎裂高降。用于区分降调的区别特征有五对:调域[±中域],调长[±长],调拱[±直],调高[±高调头],再调高[±高调尾]。单域语言中最多三个降调,双域语言中可有四个降调。 This article reports a new decrease in Fuqing dialect in Fujian Province: short-cut is also divided into two categories. Down the original six sub-ten, now found that there are seven types of eleven. Type seven is from the transfer, increase, adjust the arch to define. Five long down: high and low, low down, slightly down, high bends, low convex; two short: short high down, short down. All seven modulations appear in the middle. Among them, four types also appeared in the low field: the relaxation of the sound is long and convex (bending deformation), the relaxation of sound is short and short, the relaxation of sound is low and the height of the crack is descending. There are five distinguishing features for distinguishing between the descending features: adjusting the domain [± midfield], adjusting the length [± length], adjusting the arch [± straight], raising the [± height profile] . Up to three drops in a single-domain language, and four drops in a dual-domain language.
