The following are the expressions for the mean pressure set up at the detection plate and for the time of the signal to progagate from the radiator to the detector:这里是1个公式,省略) where Re is the real part of the expression appearing within the braces, 0 is the density of the medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in the medium, d2 = I +(r/zcos 8, z is the distance between the emitting and receiving plates, B is the angle between the axis of the acoustic channel and the axis of the tube, r = vro/c, v is the flow speed of the fluid, d is the diameter of the pipe, m is the circular frequency, k is the wave number, where a is the radius of the plate (this is taken as the same for the emitting and receiving plates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, and The triple sums in the expressions for N~ and N2 may be neglected if the flow speed is low, since the contributions for these become negligible.
以下的表情为代表的压力设置在检测板甲,手持骑枪和时间的信号 progagate从散热器排出到检测器(这里是1个公式、省略)。在什么地方才是真正的出现在背带,表现为0密度的吗当时的媒介的振幅振动速度、c是声音的速度中、d2 =我+ r / z,8、z是距离的发射和接收板、B之间的角度对声信道和轴轴管,r = vro / c,v的流体的流动速率公式,d 管直径的圆频率,m,凯西是波数公式* n,一个是半径的板(这是作为相同的发射和接收吗为了简单,但板板是毫无困难地讨论不同半径)、镁-,~的振动频率的发光,。总结了三倍的表达方式和N2 ~能忽略的流量速度低,因为这些变得微不足道的贡献。

So we designed a adaptive synchronizing controller based on hereinbefore hardware environment: first a small magnitude reference signal r is outputted to system through the signal card (to ensure that the vibrating system works in a linear state), and this signal is sent to the moving coil of vibrator through the power amplifier, so vibration is produced through electromagnetic induction. Secondly the vibration signal can feedback to the data acquiring card in the servo system through the acceleration sensor on the Vibroseis reactor M〓 and the base-plate M〓, then the computer can get the current vibrating state y〓 of the coil of vibrator according to the feedback information from the data acquiring card, and give a real time comparing between the current state y〓 and the reference output y〓 of the set-in reference model with current reference input being r , then regulates the correlative controlling parameters according to the error e〓=y〓-y〓 till y〓→y〓, finally normal signal sweeping begins with a certain phase fixed. Meanwhile a synchronization signal for seismic signal record is sent to seismograph from synchronization signal outputting component in the Vibroseis system to perform the controlling process of synchronization of sweeping phases.
为此,我们基于以上的硬件环境设计了一个自适应同步控制器:首先通过信号发生卡对系统输出小幅度的参考信号r(从而保证振动系统工作处于线性状态),信号通过前置放大器、功率放大器等送到激震器动圈,并通过电磁感应产生振动,振动信号通过可控震源激震器反应块M〓和基板M〓上的加速度传感器反馈给伺服系统中的数据采集卡,工控计算机根据采集卡的反馈信息,获取当前激震器动圈的振动状态y〓,并实时地将该状态与内置的参考模型在当前参考输入r下的参考输出y〓进行辨识,再将两者输出误差e〓=y〓-y〓对系统的有关控制参数进行调整,直至y〓→y〓,最后在经过某一固定的相位后,开始信号的正常扫描过程,与此同时,由可控震源系统的同步信号输出部件向地震仪送出一地震信号记录同步信号,进而完成扫描相位同步控制过程。
