Ukungenelela kwe-LMEC-15, ukuSuswa kunye nokuLinganiswa kweVelocity kweLiza eliSandi
Qaphela: i-oscilloscope ayifakwanga
Kwizicelo ezisebenzayo, umlinganiso wesantya sokusasazeka kwe-ultrasonic ubaluleke kakhulu kumlinganiso we-ultrasonic esukela, ukubeka indawo, ukuhamba kwe-velocity yolwelo, imodyuli ye-elastic kunye neqondo lobushushu begesi kwangoko. Isantya sesilinganiselo somlinganiso esibanzi sovavanyo oluveliswa yinkampani yethu sisixhobo sovavanyo oluninzi. Ayikwazi nje ukugcina imeko yokuma kwamaza nokuphazamiseka kwesandi, kulinganisa isantya sokusasazeka kwesandi emoyeni, kodwa ikwaqwalasele ukuphazamiseka kokuqhekeka kabini kunye nokusasazeka okukodwa kwesandi sokulinganisa, ukulinganisa ubude bamaza esandi emoyeni, jonga uphazamiseko phakathi kwentsingiselo yamaza oqobo kunye namaza abonakalisiweyo, njl. Ngokwenza ulingelo, abafundi banokuyazi imigaqo-siseko kunye neendlela zovavanyo zethiyori yentshukumo.
Uvavanyo
1. Ukuvelisa nokufumana i-ultrasound
2. Linganisa isantya somoya emoyeni usebenzisa iindlela zokuphazanyiswa kwesigaba kunye nesandi
3. Funda ukuphazanyiswa kwesandi esibonakalisiweyo kunye nesokuqala, okt iliza lesandi "LLoyd mirror" ulingo
4. Qwalasela uze ulinganise ukuphazamiseka kwesambatho esiphindwe kabini kunye nokusasazeka okukodwa kwesandi
