Mbiri ya Ultrasound ndi Kupeza

Ukadaulo wa ultrasound wazachipatala wapita patsogolo mosalekeza ndipo pakadali pano ukuchita gawo lofunika kwambiri pozindikira ndi kuchiza odwala. Kukula kwa ukadaulo wa ultrasound kumachokera ku mbiri yosangalatsa yomwe yatenga zaka zoposa 225. Ulendowu umaphatikizapo zopereka kuchokera kwa anthu ambiri padziko lonse lapansi, kuphatikizapo anthu ndi nyama.

Tiyeni tifufuze mbiri ya ultrasound ndi kumvetsetsa momwe mafunde amawu akhala chida chofunikira chodziwira matenda m'zipatala ndi zipatala padziko lonse lapansi.

Kuyamba Koyambirira kwa Echolocation ndi Ultrasound

Funso lofala kwambiri ndi lakuti, ndani anayamba kupanga ultrasound? Katswiri wa sayansi ya zamoyo wa ku Italy, Lazzaro Spallanzani, nthawi zambiri amatchulidwa kuti ndiye amene anayambitsa kafukufuku wa ultrasound.

Lazzaro Spallanzani (1729-1799) anali katswiri wa sayansi ya zamoyo, pulofesa, komanso wansembe amene mayesero ake ambiri adakhudza kwambiri kuphunzira za biology mwa anthu ndi nyama.

Mu 1794, Spallanzani anaphunzira za mileme ndipo anapeza kuti imagwiritsa ntchito mawu osati kuona, njira yomwe tsopano imadziwika kuti echolocation. Echolocation imaphatikizapo kupeza zinthu mwa kuwonetsa mafunde a mawu kuchokera pa izo, mfundo yomwe imagwiritsa ntchito ukadaulo wamakono wa ultrasound.

Kuyesera Koyambirira kwa Ultrasound

Mu buku la Gerald Neuweiler lakuti *Bat Biology,* iye akusimba za kuyesera kwa Spallanzani ndi akadzidzi, omwe sakanatha kuuluka mumdima popanda kuwala. Komabe, pamene kuyesera komweku kunachitika ndi mileme, iwo anauluka molimba mtima m'chipindamo, kupewa zopinga ngakhale mumdima wonse.

Spallanzani adachitanso zoyeserera pomwe adayang'ana maso a mileme pogwiritsa ntchito "singano zofiira," komabe iwo adapitiliza kupewa zopinga. Anazindikira izi chifukwa mawaya anali ndi mabelu omangiriridwa kumapeto kwawo. Anapezanso kuti atatseka makutu a mileme ndi machubu amkuwa otsekedwa, adataya luso lawo loyenda bwino, zomwe zidamupangitsa kuganiza kuti mileme imadalira phokoso poyenda.

Ngakhale Spallanzani sanazindikire kuti mawu omwe mileme inkapanga anali oti anthu azilankhula ndipo sanali kumva, iye anaganiza molondola kuti mileme inkagwiritsa ntchito makutu awo kuti izindikire malo ozungulira.
