noise background

基本解釋

Besides, with smaller noise background, neuron itself is still able to normally work due to its anti-noise property.
此外，神經(jīng)元本身也具有一定的抗噪性，這使得神經(jīng)元在較小噪聲背景下仍能正常工作。
By means of the principle of correlation analysis, this paper introduces an approximate method for estimating signal-to-noise ratio on random noise background.
本文利用相關(guān)分析的原理，提出一種在隨機(jī)噪音的背景上估算信噪比的近似方法。
TV target tracing system has following features: real-time, image indistinctness on the ground of dynamic tracing and external environmental distortion, high noise background intensity and so on.
電視目標(biāo)跟蹤系統(tǒng)實(shí)時性強(qiáng)，由于是動態(tài)跟蹤和外界環(huán)境干擾，所以導(dǎo)致圖像不清晰、背景噪聲較強(qiáng)。

So hopefully, the first experiment he did, which I know that they certainly did do was maybe it's just background noise, right?
做的第一個實(shí)驗(yàn)，我相信他們肯定,是這樣做的？

And the fact that we're always facing some risk of death recedes into the background in the way that most of us don't hear background noise-- that what jumping out of an airplane does for you is it spikes the risk of death.
我們一直面對的某些死亡的風(fēng)險,這種情況下變成了背景聲音,因?yàn)槲覀兇蟛糠秩硕悸牪坏奖尘暗脑肼?,而跳下飛機(jī)帶給你的,是死亡的風(fēng)險上升。
