The supersonic waves diagnosis machine is use to study the body tissue of human condition. Especially stady the pathological changes neal condition of patholoyical changes and the machine could display amount about the part of patholoyical changes, the distribation staus, the position, the configuration and the site that wirltobe some important points. These have many electron element to gather the supersoric waves diagnosis muchine. So if have one part was broken that machine will not to work. This condition will find out from external ,and there have some condition need to use the log that could find it. So,I will introduce some breakdown condition and maintain.
