Izixhobo ze-LMEC-16 zoMlinganiselo weSound Velocity kunye ne-Ultrasonic Range

Inkcazelo emfutshane:

Isantya sokusasazwa kwezandi zesandi sisixa esibalulekileyo somzimba.Kwinqanaba le-ultrasonic, ukubekwa, umlinganiselo wesantya solwelo, umlinganiselo wemodyuli elastic, umlinganiselo wobushushu begesi ngoko nangoko, uya kubandakanya isantya sesandi somzimba.Ukudluliselwa kunye nokwamkelwa kwe-ultrasound kukwayenye yeendlela ezibalulekileyo zokulwa nobusela, ukubeka iliso kunye nokuxilongwa kwezonyango.Esi sixhobo sinokulinganisa isantya sokusasazwa kwesandi emoyeni kunye nobude bezandi zamaza emoyeni, kwaye songeze umxholo wovavanyo we-ultrasonic rangeing, ukuze abafundi bakwazi ukulawula imigaqo esisiseko kunye neendlela zovavanyo lwethiyori yamaza.
