摩擦声

The experimental results reveal that there is no apparent difference in the frequency of sounds generated by the friction and collision between two stones, although the sounds may differ in pressure.

由实验结果可知，摩擦与撞击这两种不同的运动机制所产生的地声音频讯号，除声压强度上会有显著的差异之外，其在频谱上并无太大的差异性存在，这可能是因为摩擦运动基本上也可视其为无数个小撞击运动，因此其所产生之地声声纹基本上大同小异。

During all these maneuvers, limitation with or without pain in joint crepitus are assessed.

在所有这些运动中，可评估关节摩擦声中关节活动有/无痛感受限。

In the quiet of that place even the voice of the surf is reduced to a whispered echo and the sounds of the forest are but the ghosts of sound--the faint sighing of evergreen needles in the moving air; the creaks and heavier groans of half-fallen trees resting against their neighbors and rubbing bark against bark; the light rattling fall of a dead branch broken under the feet of a squirrel and sent bounding and ricocheting earthward.

置身于此地的宁静之中，连拍岸的海浪声也减弱为喃喃的回响，而森林之声也宛如声之幽灵——四季常青的松针在风中微微叹息；半倒的树靠在邻树上，树皮互相摩擦发出阵阵咯咯声和更重的呻吟声；被松鼠踩断的枯枝掉地后反复弹动，发出轻微的嘎嘎声。

That grating sound you're making is the most "raucous" noise I've ever heard.

你发出的那个刺耳的摩擦声是我听过的最难听的声音。

The roar and the screech of metal as the braking train bore down on them.

接着 正在刹车的列车带着刺耳的金属的摩擦声向他们冲了过来。

We put ashore at Tagus Cove in the bronze light of late afternoon, scraping the bow of our Zodiac onto the hard black sand beach.

我们只听见船头处不时传来刺耳的摩擦声，最后船只终于停靠在坚硬的沙滩上。

The teacher's chalk grated on the blackboard.

老师的粉笔在黑板上发出刺耳的摩擦声。

The same goes fo-r another rather extreme example, Enrico Caruso's earliest reco-rdings from 1902 (Naxos Histo-rical). Yes, the surface noise of the shellacs is presented in just as much detail (if not mo-re) as Caruso's voice, but once you listen through that you can discover a dimensionality in the reco-rding that wasn't there befo-re.

同样另外一个例子是Enrico Caruso's 在1902年的录音(Naxos Histo-rical)，胶唱片与唱头的摩擦声伴随着 Caruso 的歌声，但当你一听到时，却感觉到音场的宽广是以前没有过的。

Reasons:(1) If metal friction sound is the turbocharger rotor-bearing or thrust bearing wear too much, turbocharger impeller and shell friction generated.

原因： （1）如有金属摩擦声，是增压器转子轴承或止推轴承磨损过多，叶轮与增压器壳摩擦而产生。

In the discotheque of these DJ music like a hand rotating friction piercing sound, has been let go is another one song, so could constitute an endless sowing the height match the music.

在迪斯科舞厅中的这些DJ喜欢用手转动唱片发出刺耳的摩擦声，放手时已是另一条曲子，如此构成一个可以无止境播下去的音乐大拼盘。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
