噪声特性 [环境] noise characteristic
noisiness
- 出色的噪声特性和固定频率工作能很容易的实现快速滤波。
Outstanding noise characteristic and fixed frequency work can easily filter the waves fast. - 使用声强法对木工带锯机的噪声特性进行了测量,测得三面的声强值和噪声的矢量图、等高线图、三维图。
The noise characteristics of the idle bandsaw were measured with sound intensity method. Thevalues of sound intensity. vector chart, contour chart and mesh chart of noise were obtained. - 该设计在DDS信号产生部分运用外部时钟倍乘方式和防止时钟泄漏等措施,获得了更好的杂散与噪声特性;
The scheme of external clock frequency multiplying and measures for preventing clock leakage are adopted in DDS signal generator, thus featuring better spurious and noise characteristic.
