Kuchokera ku kusintha kwa kupanga mipira ya World Cup, onani kugwiritsa ntchito laser mumakampani opanga nsalu
Kuyambira pa June 14, World Cup ya 2018 ku Russia yayamba bwino kwambiri, ndipo zigoli zambiri zakale zagoledwa m'masewera ambiri. Komabe, pankhani ya mpira wa World Cup, n'zovuta kulingalira momwe mpira ungasokedwe pamodzi. Ndipotu, kupatula kukhala wozungulira nthawi zonse, mpira wakhala ukuwoneka m'njira zosiyanasiyana, kuyambira zaka 85 za World Cup.
Mpira wa m'ma 1930 unapangidwa ndi chikopa, chomwe chinkasokedwa ndi manja ndi antchito aluso. Pachifukwa ichi, mpira si mpira wozungulira panthawiyi, ndipo nthawi zonse umakhala ndi mabowo.
Mu World Cup ya 1986 ku Mexico, kwa nthawi yoyamba, FIFA yagwiritsa ntchito mpira wopangidwa ndi zinthu zonse ngati gawo lakunja. Chifukwa cha kupita patsogolo kwaukadaulo, wopangayo wagwiritsa ntchito njira yatsopano yosokera chikopa, yomwe imachepetsa kuchuluka kwa zidutswa za chikopa za mpira wapaderawu poyerekeza ndi mpira wapadera wakale. Kale, mpira unkasokedwa ndi manja ndi antchito aluso, zomwe zimapangitsa mpirawo kukhala wovuta kwambiri, ndipo chifukwa chakuti malo pakati pa zidutswa za chikopa ndi akulu kwambiri, bwalo lonselo silikwanira.
Pa World Cup ya 2006 ku Germany, Adidas anasiya kotheratu njira yosokera ndi manja ndipo anayamba kugwiritsa ntchito njira yotenthetsera kuti achepetse kusagwirizana kwa pamwamba pa bwalo chifukwa cha kusoka kwa chikopa.
Mpira wosokedwa ndi laser ndi mpira wolumikizidwa bwino ndi kutentha. Ntchito yabwino kwambiriyi ili ndi ulemerero wa samba wa World Cup ku Brazil! Mpira wolumikizidwa ndi kutentha uli ndi ubwino woonekeratu kuposa mpira wosokedwa ndi manja ndi makina: kukonza kapangidwe kake kozungulira, kusunga mawonekedwe ozungulira pokankha, zomwe zimathandiza kuwonjezera mphamvu ndi kulondola; njira yatsopano yopangira ma patches imachotsa zolakwika zozungulira ndikupanga bwalo Lozungulira bwino komanso lolondola kwambiri. Ukadaulo wogwirizanitsa kutentha umapangitsa zidutswazo kukhala zoyandikana bwino, zomwe zimapangitsa mpirawo kukhala wosalala komanso wozungulira mosalekeza. Komabe, ukadaulo uwu sunakhwime kwambiri pakadali pano, ndipo nthawi zina mabuloko omwe amalumikizidwa ndi kutentha amasweka kapena kugwa.
Pa Ogasiti 3, 2005, asayansi aku Britain adasoka bwino shati pogwiritsa ntchito laser m'malo mwa nsalu. Vutoli limabweretsa mavuto atsopano ku makampani azovala zachikhalidwe. Ukadaulo watsopanowu ndi ntchito yabwino kwambiri ya Cambridge Institute of Welding Technology ku United Kingdom. Asayansi choyamba adayika madzi omwe amayamwa kuwala kwa infrared kumalo komwe shatiyo iyenera kusokedwa, kenako n’kuyika m’mbali mwake kuti madziwo alowe pakati pa zovala ziwiri zomwe ziyenera kusokedwa. Kenako, gawo lolumikizanalo limawotchedwa ndi laser ya infrared yochepa mphamvu, ndipo madzi a mankhwalawo amatenthedwa kuti asungunuke pang’ono nsaluyo ndikulumikiza gawo lomwe likuyenera kusokedwa. Kugwiritsa ntchito ukadaulo uwu kuluka mitundu yosiyanasiyana ya zovala ndikolimba kwambiri, kuposa zovala zankhondo, ndipo ndikoyenera zovala zaubweya, zovala zopumira komanso ngakhale zovala zotanuka zotchuka kwambiri. Njirayi ndi yothandiza kwambiri poluka zovala zosalowa madzi, chifukwa tsopano kusoka zovala zotere kumafuna kuletsa madzi kulowa kwa mawonekedwe, koma ndi kusoka kwa laser, mawonekedwewo ayamba kudontha atamalizidwa. Asayansi adati ukadaulowu udzapangidwanso kuti ugwiritse ntchito lasers ku bizinesi yodzipangira yokha zovala.
China ndi "mphamvu yopanga" mumakampani opanga nsalu ndi zovala. Kuti athetse vuto la kukula kwa msika, kuti akonze mpikisano wapadziko lonse ndikuwonjezera phindu, makampani opanga nsalu ndi zovala ayenera kufulumizitsa kusintha kapangidwe ka mafakitale, kuwonjezera ndalama mu sayansi ndi ukadaulo, kukonza zida zopangira zovala, kugwiritsa ntchito ukadaulo watsopano ndi njira zatsopano, ndikuwonjezera phindu lowonjezera pazinthu ndi ukadaulo.
Kugwiritsa ntchito ukadaulo wa laser mumakampani opanga nsalu ndi zovala kwawonetsa njira yomwe mabizinesi angathandizire kuti ntchito yopangira zinthu ikhale yogwira mtima, kuwonjezera phindu lowonjezera, kusintha mtundu wa kukula, kukonza njira zopangira, kusintha kapangidwe ka mafakitale, ndikusintha kuchoka pakugwiritsa ntchito ntchito zambiri kupita kukugwiritsa ntchito ukadaulo wambiri. Monga makampani otsogola mu unyolo wamakampani opanga zovala, ukadaulo wa laser uli ndi udindo komanso umagwira ntchito yofunika kwambiri pakukweza kupita patsogolo kwa makampani. Akukhulupirira kuti udzakhala ndi gawo lofunika kwambiri pakusintha kapangidwe ka mafakitale mtsogolo. Pakadali pano, kugwiritsa ntchito laser mumakampani opanga nsalu kwalowa pang'onopang'ono pakukula. Ndi kugwiritsa ntchito mwachangu ukadaulo wokonza laser, zofunikira pakupanga makina a laser zawonjezeka pang'onopang'ono. Popeza makina odulira laser ndi makina ojambula laser ali ndi zabwino zosayerekezeka pakukonza bwino, mtundu wa malonda, mtengo wopanga ndi chiŵerengero cha zolowetsa ndi zotuluka, zikuonekeratu kuti posachedwa, ukadaulo wogwiritsa ntchito laser udzawala kwambiri mumakampani opanga nsalu ndi zovala.
