杂音

In fact, the answer is fairly simple, and can be summed up in two words: ambient noise.

事实上，问题的答案非常简单，简单到可以用两个字来概括：周围的杂音。

The first thing to see, looking away over the water, was a kind of dull line -- that was the woods on t'other side; you couldn't make nothing else out; then a pale place in the sky; then more paleness spreading around; then the river softened up away off, and warn't black any more, but gray; you could see little dark spots drifting along ever so far away -- trading scows, and such things; and long black streaks -- rafts; sometimes you could hear a sweep screaking; or jumbled up voices, it was so still, and sounds come so far; and by and by you could see a streak on the water which you know by the look of the streak that there's a snag there in a swift current which breaks on it and makes that streak look that way; and you see the mist curl up off of the water, and the east reddens up, and the river, and you make out a log-cabin in the edge of the woods, away on the bank on t'other side of the river, being a woodyard, likely, and piled by them cheats so you can throw a dog through it anywheres; then the nice breeze springs up, and comes fanning you from over there, so cool and fresh and sweet to smell on account of the woods and the flowers; but sometimes not that way, because they've left dead fish laying around, gars and such, and they do get pretty rank; and next you've got the full day, and everything smiling in the sun, and the song-birds just going it!

往 水面上望去，首先看到的是灰蒙蒙的一条线——那是河对岸的树林子——别的便什么也看不清——接着是天空中有一点儿鱼肚白；然后鱼肚白多了些，逐渐朝四周散开去；接下来，远处河水的颜色淡了些，不是那么黑了，而是灰灰的了。更远处，可以看到小小的黑点子在漂过来——那是些载货的驳船之类。还有黑黑的一长条——那是木筏子。有时能听到长桨吱吱地响，或者一些杂音。四周这么寂静，声音又来自很远的远方。过了一会儿，你看到一道水纹。凭了水纹的模样，你知道那里有一块礁石，急流朝着它冲过去，流水飞溅，成了这个模样。你看到，雾气袅袅上升，离开水面，东方红了起来，河面红了起来。你可以看到对岸河边树林子边上一处原木搭成的小屋，那可能是一个木材场，在那里堆着的一堆堆木材，中间却是空的，容得狗钻来钻去，为了能叫人家上当①。然后微风轻拂，从河上一阵阵吹来，那么凉凉的，那么清新，闻起来那么甜美，这是全凭了那些树林子和那些鲜花的缘故。可有时候也并非全是如此美妙。

I hear murmurs at the left side of the breast bone.

我听杂音在胸骨左侧。

It is heart sounds and murmurs that phonocardio-graphy records, which may help to elucidate difficult problems of auscultation.

是心音和杂音由心音描记法记录下来，这可有助于解释听诊中碰到的疑难问题。

This kind of digital PCG analyzer based on LabVIEW can be used for assistant diagnosis of cardiac Arrhythmia and cardiac abnormal noise, and as a teaching tool for clinical auscultation.

基于虚拟仪器的数字心音图分析仪能够为心率失常和异常杂音等疾病提供辅助诊断，同时也可作为听诊教学的教学工具。

There's a lot of background noise here; could you speak a little louder?

这里的背景杂音太大了，可以请您讲大声一点吗？

I learned to tune out the background noise.

我学会了不去注意背景杂音。

Methods Using Seldinger technique method,guide Magic-BD micro-catheter with Balt detachedable rubber ball to the fistulas level,when verified the ball inside the fistula of carotid-cavernous sinus but outside the carotid artery,filled the ball fully enough with iodine material until the abnormal noise disappear and release the ball remained the internal carotid artery patent.

采用Seldinger法插入导管鞘后，用带Balt可脱球囊的magic-BD导管透视下经导引管送达瘘口水平，当球囊突然"低头"或改变方向时，表示球囊已通过瘘口，进入海绵窦。以等渗造影剂交换气体后充盈球囊至杂音消失，造影证实瘘闭塞完全，并保持颈动脉通畅。

Bizarre noises are emitted from the body, a body known well enough by its owner to recognise the noises as extrinsic; air is pumped in and out of orifices as if by a bicycle pump.

异乎寻常的杂音从身体发出，这一身体被主人充分了解以致于能够识别这些杂音是外来的；空气被泵入泵出孔穴就像是通过一个自行车打气筒。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
