衰减器

A tape simulator built in the cassette tape type digital audio/video device comprises left and right reel hubs inserted in both driving reels of the cassette deck player to be rotated; and a rotation speed attenuating unit for attenuating the rotation speeds of the left and right reel hubs to at a predetermined rate by providing resistance to the left and right reel hubs rotated by the driving reels.

This dissertation has studied various architectures of Sigma-Delta modulator systematically. According to power dissipation, stability and circuit implementation, a 2-2 cascade architecture is introduced. Oversampling ratio is 32. The attenuation factors of each integrator and interstage coefficients are obtained from behavioral simulation.

本论文系统地研究了∑A调制器的各种体系结构，根据功耗、稳定性以及电路实现等方面综合考虑，∑A调制器采用级联2—2结构，过采样比为32，并通过行为级仿真确定了积分器的增益衰减因子及级间耦合系数。

It has been proved, that the attenuation value of bridge circuit is not equal to the sum of two terminal attenuation, and it concerned with impedance of wave trap, substation bus impedance, and phase-angle of...

分析和计算表明，桥路衰减的数值不能简单地看作两个终端衰减之和，而与阻波器阻抗、线路阻抗、变电站母线阻抗和邻相同频寄生信号的相位角等参数有关。

The intensity of the ultrasonic wave will increase when the ultrasonic wave is focused by the sound lens in rock stratum.

然而 ，这种方法要受到两个因素的制约：一是增大超声换能器的功率，必然要增大超声换能器的尺寸，这在本身尺寸就很小的油井中是有一定限度的；二是当超声换能器辐射出的超声波的强度过大时，在超声换能器的周围要发生强烈的空化现象，产生大量的气泡，这些气泡将对超声波产生强烈的散射作用，导致超声波的衰减，反而降低超声波在岩层中的传播距离[1] 。
