摩擦音

In the production of a plosive, the air-stream is obstructed completely both in the oral and nasal tracts, so that when the closure in the oral tract is suddenly released, the compressed air rushed in the oral tract is suddenly released, the compressed air rushes out and produces an explosive sound.

根据气流通过口腔时产生的不同效果给辅音分类，可将辅音分为爆破音、摩擦音、塞擦音、鼻音和舌边音。另外，我们将半元音也放在这一部分，方便练习掌握。

Of the 8 patients,2 with Chinese pharyngeal fricatives,2 with congenital velopharyngeal insufficiency,2 with Chinese palatalized misarticulation,and 2 with normal articulation.

8例筛选患者，咽喉摩擦音、先天性腭咽闭合功能不全、腭化构音和正常构音各2例，其中男性4例，女性4例，平均年龄18岁。

Listen and repeat the sentences paying special attention to the pronunciation of stops/fricatives/front vowels.

听这些句子并且重复。做这样练习时一定要注意一些发音的规律，比如说像摩擦音啊，前元音啊等等

WT-3 could produce vowels more clearly, and produce stops, fricatives and nasal sounds with the new flexible mechanisms that functioned as the human vocal tract area and the other mechanisms.

WT-3能把元音发得更清晰、并能用新型的灵活的机制和其它机制做出停顿、发出摩擦音和鼻音。这些新型的灵活机制的功能就像人类的发音器官系统一样。

Variable bit-rate allows a codec to change its bit-rate dynamically to adapt to the "difficulty" of the audio being encoded. In the example of Speex, sounds like vowels and high-energy transients require a higher bit-rate to achieve good quality, while fricatives e.g.

变比牲率允许编解码器动态调整比特率以适应的音频解码的&难度&，拿Speex来说，像元音和瞬间高音则需较高比特率来达到最佳效果，而摩擦音则用较少的比特即可完成编码。

The findings on physical examination included atrial fibrillation, a diffuse anterior chest heave and friction rub, and severe right heart failure.

在20出头时初次被诊断为三尖瓣下移，入院三年前患者拒绝了心脏移植手术，入院后检查发现房颤、弥散性心前区搏动和心包摩擦音，以及严重的右心衰竭。

The fibrin often results in the the finding on physical examination of a "friction rub" as the strands of fibrin on epicardium and pericardium rub against each other.

纤维素性心包炎通常是由于体检时出现胸膜摩擦音而被发现。

Comparison was made about the clinical performance, such as 10 meters walking time, patient self-appraisal, squat activities and sporting pain, joint swelling, joint effusion and bone friction sound of the three groups of patients before treatment and one months, three months, six months, one year after treatment.

对比观察三组患者治疗前和治疗1月、3月、半年、1年时10米步行时间、患者自我评价、下蹲活动及运动疼痛、关节肿胀、关节腔积液、骨摩擦音等临床表现。

Semivowels are vowel-like consonants: that is, the air-flow is not stopped or impeded so as to cause a friction-sound, but the aperture through which the air passes is smaller than the aperture of any vowel, such as

半元音是有些像元音的辅音，也就是说，发半元音时，气流并不需要受阻而形成摩擦音，但气流通过的缝隙要小于发元音时通过的缝隙。例如

半元音是有些像元音的辅音，也就是说，发半元音时，气流并不需要受阻而形成摩擦音，但气流通过的缝隙要小于发元音时通过的缝隙。例如：1。/w/：舌后软颚半元音

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
