您要查找的是不是：
- ground noise margin 接地噪声边际
- The engine gave forth a grinding noise, then stopped. 发动机发出一阵轧轧声，随即停了下来。
- Noise margin: The term noise refers to any undesirable signal that is superimposed on a generated signal. 噪声极限：噪声这个概念指任何正常信号之外不需要的信号。
- Noise margin:The term noise refers to any undesirable signal that is superimposed on a generated signal. 噪声极限:噪声这个概念指任何正常信号之外不需要的信号。
- Noise margin refers to the maximum noise voltage that can be added to the generated signal in a digital circuit before an undesirable change is caused in the circuit output. 噪声极限就是指可以加在数字电路的正常信号上，而又不对正常输出造成危害的最大噪声。
- Using Schottky barrier diodes for D1 and D2 rather than common diodes reduces the low-level voltage on the bus, improving the noise margin. 使用肖特基二极管D1和D2，而不是普通二极管，为的是减少总线上低状态电压，改进噪声极限。
- Comparing with MLT-3 encoding scheme, the minimum distance between two levels of PAM-5 is only half that of MLT-3.This is equivalent to a loss of 6dB noise margin. PAM-5 编码跟100BASE-TX 所用的MLT-3编码相比，相邻电平之间的间距减小了一半，等效于损失了6dB的信噪比。
- The engine gave forth a grinding noise,then stopped. 发动机发出一阵轧轧声，随即停了下来。
- The products of DPCA have adopted a lot of measures to reduce the wind noise, engine noise, ground noise and car parts interfering and hitting noise in the phase of developing. 神龙公司的产品在开发阶段采用了大量措施来降低风噪声,发动机噪声,地面噪声以及车上零件干涉和碰击噪声。

- He lifted a pail of water from the ground. 他把一桶水从地上提了起来。
- Rachel who died last week was still above ground. 雷切尔上星期去世，现在还没安葬。
- Ambipolar transistors are attractive for realizing complementary-like organic integrated circuits, which operate with low power dissipation, wide noise margins and great operational stability. 目前，国际上有机双极性晶体管的研究由于受到种种限制性能并不理想，很少能获得对称性良好的高性能器件。
- This car really comes into its own on rough ground. 这辆汽车在颠簸的路上才真正显示出它独特的性能。
