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.
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.
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.
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.
Objective:To investigate the effect of corneosclera repair and ultrasonic emulsification and cataract aspiration followed by artificial vitreous implantation in ocular penetrating injury.
To investigate the effect of corneosclera repair and ultrasonic emulsification and cataract aspiration followed by artificial vitreous implantation in ocular penetrating injury.
Purpose To evaluate the feasibility and superiority of the catarct ultrasonic emulsification, artificial lens implantation united micro trabecula resection adopt surface anesthescia.
The lesions can be showed as arteriitis,arteriectasis,aneurysm and arterial stenosis stenosis..Ultrasonic cardiography is the first choice to detect the lesions.
Echolocation is great for hunting, but Holdereid says it's also a potential weakness for bats—because in the ultrasonic world, these calls are very, very loud.
