你正在和一个人谈话，但是信号和噪音的比率低，也就是说，对方的声音(信号)，相对于周围的谈话声(噪音)是安静的。
You're in conversation with one person but the signal to noise ratio is low, meaning his voice, the signal, is quiet relative to the ambient conversational noise.
新的连接相当地快，即使是在信号噪音比率相当糟糕的情况下。
The new links are significantly faster, even when the signal-to-noise ratio is clearly worse.
实验仿真和某型雷达记录仪测试结果表明，该算法具有较好的压缩比率及较高的信号恢复质量。
By experimental simulation and test result of a certain radar recording meter, it shows that this algorithm has a higher compression rate and a better quality of signal recovery.
所有病灶在指数扩散系数像上的信号强度比率要比扩散加权像减低。

这本由采样事件信号，政企分开转发和反射波，然后表演比率，是直接关系到反射和透射系数的两个港口。
It does this by sampling the incident signal, separating the transmitted reflected waves, then performing ratios that are directly related to the reflection transmission coefficients of the two-port.
在审视过的系统中，一半以上显示出红外光的气盘信号，而在非常年轻的天体间，这个比率可达到80%。
Of those surveyed, more than half evince infrared disk signatures, and the fraction may be as high as 80 percent among the very youngest objects.
分贝通常表示两个声音信号或电力信号在功率或强度方面的相对差别的单位，相当于两个水平的比率的常用对数的十倍。
A unit used to express relative difference in power or intensity, usually between two acoustic or electric signals, equal to ten times the common logarithm of the ratio of the two levels.
