百度 尽管如此，我依然觉得全新奥迪A8L是这个级别当中科技含量最高的车型，比如：全新奥迪A8L是国内首款搭载48V轻混系统的量产车，也是同级中首款全系标配48V轻混系统的车型；全新奥迪A8L是首款搭载高清矩阵式激光大灯的车型；全新奥迪A8L是全系标配全时四驱的D级车；全新奥迪A8L是同级别中全轮转向效果最好的车型（转向直径米）；全新奥迪A8L首次使用OLED光源尾灯，等等......48V全电气化驾驶系统这是汽车向智能汽车转变的一大步全电气化驾驶系统是一个整车概念，但是我们听到最多的就是48V轻混系统。 Legend: unrounded ? rounded |
The open front unrounded vowel, or low front unrounded vowel,[1] is a type of vowel sound used in some spoken languages. It is one of the eight primary cardinal vowels, not directly intended to correspond to a vowel sound of a specific language but rather to serve as a fundamental reference point in a phonetic measuring system.[2]
The symbol in the International Phonetic Alphabet (IPA) that represents this sound is ?a?, a double-story lowercase a. In the IPA vowel chart it is positioned at the lower-left corner. However, the accuracy of the quadrilateral vowel chart is disputed, and the sound has been analyzed acoustically as extra-open at a position where the front/back distinction has lost its significance. There are also differing interpretations of the exact quality of the vowel: the classic sound recording of [a] by Daniel Jones is slightly more front but not quite as open as that by John Wells.[3]
In practice, the symbol ?a? is often used to represent an open central unrounded vowel.[4] This is the usual practice, for example, in the historical study of the English language. The loss of separate symbols for open and near-open front vowels is usually considered unproblematic, because the perceptual difference between the two is quite small, and very few languages contrast the two. If there is a need to specify the backness of the vowel as fully front one can use the symbol ????, which denotes a lowered near-open front unrounded vowel, or ?a?? with the IPA "advanced" diacritic.
Features
[edit]- Its vowel height is open, also known as low, which means the tongue is positioned far from the roof of the mouth – that is, low in the mouth.
- Its vowel backness is front, which means the tongue is positioned forward in the mouth without creating a constriction that would be classified as a consonant. This subsumes central open (central low) vowels because the tongue does not have as much flexibility in positioning as it does in the mid and close (high) vowels; the difference between an open front vowel and an open back vowel is similar to the difference between a close front and a close central vowel, or a close central and a close back vowel.
- It is unrounded, which means that the lips are not rounded.
Occurrence
[edit]Many languages have some form of an unrounded open vowel. For languages that have only a single open vowel, the symbol for this vowel ?a? may be used because it is the only open vowel whose symbol is part of the basic Latin alphabet. Whenever marked as such, the vowel is closer to a central [?] than to a front [a]. However, there may not actually be much of a difference. (See Vowel#Acoustics.)
