Figure 4:Measurement geometry.The black strips represent current-injecting electrodes,and the red dots depict the tips of the
recording electrodes.The dashed green arrow is the ultrasound beam axis and the solid blue arrow represents the current..
Figure 5:Experiment timing during parameter sweep.As seen in Figure 2,a trigger pulse from the HP33120A signal generator is sent
to an FPGA,which triggers the ultrasound pulse such that it coincides either with the current maxima or minima.
Figure 6:Experiment timing.As seen in Figure 2,a trigger pulse from the HP33120A signal generator is sent to an FPGA which
triggers the ultrasound pulse and the data acquisition after a variable delay.The delay is controlled via a parallel port from a computer

答案

楼主请追加点分吧.
图4 测量几何学.黑色条代表电流注入电极,红色虚线表示记录电极的顶端.
虚线的绿色箭头是超声波束轴线,蓝色的实线箭头代表电流.
图5 在参数扫描过程中的实验扫描.如在图2中看到的那样,来自HP33120A信号发生器的触发脉冲被送到FPGA,它触发超声波脉冲,从而和电流最大值或电流最小值一致.
图6 实验的定时.如图2所示的那样,来自HP33120A信号发生器的触发脉冲被
送到一个EPGA,EPGA触发超声波脉冲,并在可变的延迟后触发数据采集.
延迟通过计算机的并行端口进行控制.
