The lesions can be showed as arteriitis,arteriectasis,aneurysm and arterial stenosis stenosis..Ultrasonic cardiography is the first choice to detect the lesions.
In 29 stenotic tumors that panendoscope could not transverse, thin ultrasonic probe still could pass though them with complete scanning in 21(72%) of them.
Methods The scrotum including its root and inguinal region was scanned directly to observe the diameter,the ultrasonic features and the vasculation of the spermatic cord.
Then ultrasonic wave and solvent were exerted into the crystallizable solution to change its natures,adjust the formation of crystal water and affect the change of crystal configuration.
In ultrasonic field, authors studied solidify of water base epoxy dope and suspend and decentralization of millicron grain in water base epoxy resin, developed a series of water base dope.
