Mbiri ya Ultrasound ndi Kupeza

Ukadaulo wamankhwala a ultrasound wawona kupita patsogolo kosalekeza ndipo pakali pano ukugwira ntchito yofunika kwambiri pozindikira ndi kuchiza odwala. Kukula kwa ukadaulo wa ultrasound kumachokera m'mbiri yochititsa chidwi yomwe imatenga zaka 225. Ulendowu umaphatikizapo zopereka zochokera kwa anthu ambiri padziko lonse lapansi, kuphatikizapo anthu ndi nyama.

Tiyeni tifufuze mbiri ya ultrasound ndikumvetsetsa momwe mafunde amawu akhalira chida chofunikira chowunikira zipatala ndi zipatala padziko lonse lapansi.

Chiyambi Choyambirira cha Echolocation ndi Ultrasound

Funso lodziwika bwino ndiloti, ndani adayambitsa ultrasound? Katswiri wa zamoyo wa ku Italy Lazzaro Spallanzani nthawi zambiri amatchulidwa kuti ndiye mpainiya wa ultrasound.

Lazzaro Spallanzani (1729-1799) anali katswiri wa zathupi, pulofesa, ndi wansembe yemwe kuyesa kwake kochuluka kunakhudza kwambiri maphunziro a biology mwa anthu ndi nyama.

Mu 1794, Spallanzani adaphunzira mileme ndipo adapeza kuti imayenda pogwiritsa ntchito mawu osati kuwona, njira yomwe masiku ano imatchedwa echolocation. Echolocation imaphatikizapo kupeza zinthu powonetsa mafunde a phokoso kuchokera pa izo, mfundo yomwe imathandizira luso lamakono lachipatala la ultrasound.

Mayesero Oyambirira a Ultrasound

M’buku la Gerald Neuweiler lakuti *Bat Biology, * akufotokoza zimene Spallanzani anayesera ndi akadzidzi, amene sakanatha kuwuluka mumdima popanda kuwala. Komabe, pamene kuyesa komweko kunachitika ndi mileme, iwo molimba mtima anawulukira m’chipindacho, kupeŵa zopinga ngakhale mumdima wathunthu.

Spallanzani adayesanso kuyesa komwe adachititsa khungu mileme pogwiritsa ntchito "singano zotentha kwambiri," komabe adapitilizabe kupeŵa zopingazo. Anatsimikiza zimenezi chifukwa mawayawo anali ndi mabelu omangika kumapeto kwake. Anapezanso kuti akatsekereza makutu a mileme ndi machubu otsekeka, amalephera kuyenda bwino, zomwe zinachititsa kuti aganize kuti mileme imadalira phokoso pakuyenda.

Ngakhale Spallanzani sankadziwa kuti mileme yomwe inkamveka inali yongomveka komanso kuti anthu samatha kuimva, iye ananena molondola kuti mileme inkagwiritsa ntchito makutu awo kuzindikira zinthu zimene ili pafupi.
