Sending weak signals about our willingness to engage in trust or punish abuse of it makes us more vulnerable to exploitation.───对我们想加入信任的意愿发出微弱信号或惩罚滥用信任会使我们更容易被利用。

Small telescopes see a lot of sky but can detect only strong signals. Large ones, which can detect weak signals, have a narrow focus.───大型的望远镜虽可以检测到微弱的信号，却只有很小的焦距。

They check the input and output quality ensuring that weak signals are shifted to a reserve one.───他们检查输入和输出信号质量，确保弱信号被替换为储备信号。

The experiments verified that the weak signals submerged in the complex background can be enhanced efficiently by this algorithm.───通过实验证明，该算法能够有效的增强复杂背景下的微弱目标信号。

This limitation can be overcome by "repeaters, " which pick up weak signals, amplify them, and retransmit them on a different frequency.───这种限制可以被中继站所克服。中继站可以捕捉到微弱的信号，然后把它放大，再用不同的频率重新发送。

It constructs a two-dimensional block matrix to preprocess the received data vector, and then estimates the direction of weak signals.───首先构造二维阻塞矩阵对阵列接收数据进行预处理，抑制掉已知方位强干扰，再进行弱信号的谱估计。

The technology of stochastic resonance can be used to detect weak signals submerged in noise.───论文对随机共振技术运用于强噪声背景下的弱信号检测进行了研究。

Up to 80 dB on-screen dynamic range ensures visibility of weak signals in the presence of strong ones.───高达80分贝对屏幕的动态范围，确保能见度的微弱信号在场的优势。

As far as cased-hole formation resistivity logging, the key problems needed to be solved are detection of ultra-low frequency and extremely weak signals, as well as reduction of strong interferences.

The probe revealed only weak signals in genomic DNA from other cereal species, wheat, barley, maize, rice, and pearl millet, indicating that xPSF31 is a Setaria genus specific sequence.

This method also has characteristic of low amplitude detection threshold, it can detect weak signals with amplitude value smaller than 10-3 level.

An OPA128 operational amplifier with extreme low bias current and big gain is adopted for enhancing the response to weak signals.

Also its signals would contain a lot less noise, particularly important in measuring and handling very weak signals.

After this, a method for detecting weak signals in sea clutter by neural networks is presented. And the detecting model of radar is introduced.

A new circuit has been designed and developed for picking up and amplifying the weak signals of a photoelectric detector in fire detecting system.

The analysis shows that the OSF can effectively suppress multiple interferences and extract weak signals.
