1) Funnel noise
漏斗噪声
2) noise funnel

3) noise funneling
噪声漏斗效应
1.
But the existence of noise funneling in the return path of cable network in HFC system restricts the selection of modulation techniques for the return path.
但HFC网络中同轴电缆网络上行信道中存在的噪声漏斗效应限制了上行信道调制技术的选择。
4) breakout noise
泄漏噪声
1.
Based on the assumption of Nelson and Morfey that there is a constant of proportionality between the fluctuating drag force and the steady state drag force acting on an in-duct element, a pressure-based technique is proposed for estimating the breakout noise due to the vibration of the duct wall caused by the interaction of the turbulent flow and the in-duct elements.
根据Nelson与Morfey的设定,在流体质元所受波动阻力和稳态阻力之比恒定的条件下,文中推广了一种基于气压值的计算方法,用来推算由管道内部因素与湍流作用所引起的管道壁泄漏噪声之声强级。
5) leakage noise
漏泄噪声
6) signal to leakage and noise radio(SLNR)
信漏噪声比

匕00PO IOudou爆破漏斗(blasting erater)药包在岩石中爆破后,在自由面形成的凹坑。爆破漏斗是工程爆破中计算装药量和爆破体积的依据,按照爆破作用性质的不同,将爆破漏斗分为标准抛掷爆破漏斗、加强抛掷爆破漏斗和减弱抛掷爆破漏斗(见爆破作用指数)。构成爆破漏斗的要素有:最小抵抗线W;爆破漏斗半径;;爆破作用半径R;爆破漏斗深度D;爆破漏斗可见深度h和漏斗张开角(破裂角)0(见图)。蚀之 爆破漏斗图
