摘　　要：目的:对阿洛卡超声仪无图像或图像时有时无的故障检修。方法:采用对怀疑电容加入直流5V电压的方法,可快速准确的找到故障电容。结论:在维修中应首先从电源入手,测量其各路电压是否正常。在对有故障机器的检修后总结发现,电源的故障率在整台机器的故障中可达到40%以上,这一点在维修中应引起工程师的高度重视,有时可起到事半功倍的效果。Purpose： to solve imaging problems of Aloka Ultrasound Instrument. Methods： we can find the capacitance with fault quickly and accurately through joining 5 volts DC to suspected capacitance. Conclusion： During repairing, check the power first, and then measure the voltages of each pathway. We made a conclusion that the error rate of the power in the whole machine reaches up to 40%. Engineers should pay great attention to power error, sometimes this can make our work easily and fast.
