noise energy meaning in English
噪声能量
Examples
- Usually , single vector sensor will obtain infinite gain if noise energy flow can be counteracted in whole space
在理想情况下，若噪声场为各向同性噪声场，则通过声能流长时间积分，单个矢量水听器便可获得无限大的增益。 - The application of wt to power system fault signal is also discussed in the thesis . the auther also studies the application of statistics analyse theory . spectral analysis and system identify method can be used to analyse noise energy distribution and damp characteristics of bus capacitance
研究了小波变换和多分辨率结构下mallat小波分解算法分析故障暂态信号的原理和方法，用这一方法研究了故障信号的特点，性质。 - At last we give out the result of plenty of simulation data and real sar data . and we also analyze the performance of the algorithm from the point of view of different velocity , different signal / noise energy ratio , different aotufocus algorithm , different patch size
然后本文给出大量仿真数据和实测数据检测结果，分别从不同运动目标速度、不同信噪比、不同相位误差估计算法、不同分块大小等角度进行检测性能分析。 - Stochastic resonance ( sr ) is different from traditional methods ( such as correlation , equality superposition , filter etc ) in faint signal detection . sr can turn parts of noise energy into signal energy and enhance signal while wiping off noise , so that increasing the signal - to - noise rate ( snr )
随机共振检测技术与传统的弱信号检测方法(如相关、平均叠加或滤波等)不同，它可以把部分噪声能量转换成信号能量，实现增强信号能量的同时去除噪声，从而提高了信噪比。 - The frame radiated noise is one of the major noise resources of rotary machines , especially for gear case which has close shell and vibrating screen which works in vibrating ways , the frame radiated noise energy account for more than 90 % of total sound energy . so if we could not successfully resolve the problem , the noise of rotary machines would never be effectively controlled
结构噪声是旋转机械的主要噪声源之一，尤其是对于如齿轮箱这类具有封闭壳体的机械和如振动筛这类以振动为主要工作方式的机械，结构振动辐射声能占总声能的比例甚至可以达到90 95 ，因此不解决结构噪声问题旋转机械噪声就不能得到有效的控制。
