Kodi zochitika capillary ndi momwe iwo kufotokoza?

Ngati mukufuna kumwa cocktails kapena zakumwa zina kwa chubu, inu mwina mwaona kuti pamene wina wa malekezero ake ndi adatchithisira mu mlingo madzi a chakumwa ali pang'ono kuposa mu chikho kapena galasi. Zachitikiranji zimenezi? Kawirikawiri anthu sindikuganiza za izo. Koma sayansi zodabwitsa ngati nthaŵi yaitali kuphunzira bwino ndipo ngakhale nampatsa dzina lake - zochitika capillary. Anabwera yathu tipeze chifukwa chake izi zikuchitika ndipo momwe deta anafotokoza chifukwa chodabwitsa lapansi.

Chifukwa kubwera zochitika capillary

Mu chikhalidwe, chirichonse chimene chimachitika pali wololera malongosoledwe. Ngati madzi wetting (mwachitsanzo, madzi mu chubu pulasitiki), izo adzaimirira chubu, ndipo ngati si wetting (mwachitsanzo, Mercury mu cones galasi) - ndiye zasiyidwa. Komanso, Zing'onozing'ono ndi utali wozungulira capillary ndi, kuwuka kwa m'dera lokwera, kapena madontho madzi. Kodi anafotokoza zochitika ngati capillary? Physics ananena kuti iwo chifukwa cha kukhudzana ndi mphamvu ya mavuto padziko. Ngati inu muyang'ana wosanjikiza pamwamba pa madzi capillary, zikhoza kuoneka kuti maonekedwe ndi mtundu wa bwalo. Pamodzi ndi malire ake pa makoma chubu ali ndi kuthamanga mphamvu ya otchedwa mavuto padziko. Komanso, wetting madzimadzi vekitala ake malangizo akukumana downwards, pamene sanali wetting - kumtunda. Malinga ndi wachitatu lamulo la Newton, izo zivute zitani zikutipatsa wofanana ndi kuthamanga modulo kauntala. Ndipange izo tipite kapena pansi madzi mu chubu yopapatiza. Ikufotokoza mitundu yonse ya zochitika capillary. Komabe, kwa ena, anthu ambiri funso zachilengedwe adanyamuka: "Ndipo pamene siteji zochotsa kapena kutsitsa madzi?" Izi zikanakhala choncho pamene mphamvu yokoka, kapena Archimedes mphamvu sikelo mphamvu amachititsa madzi kusamukira ku chubu.

Kodi ndingatani ntchito capillary chodabwitsa?

Popeza imodzi mwa ntchito zodabwitsazi, kofala mu kupanga malo, bwino kuti pafupifupi wophunzira kapena mwana. Inu mwina kale anaganiza kuti ndi ndodo capillary.
akuphatikizapo limakupatsani kulemba pafupifupi udindo uliwonse, ndi wochepa thupi, momveka chizindikiro pa pepala kwa nthawi yaitali zinatigonjera ndi wotchuka kwambiri pakati pa kulemba fraternity. Capillary chodabwitsa amadziwikanso ankagwiritsa ntchito mu ulimi ulamuliro magalimoto ndi posungira chinyontho m'nthaka. Monga mukudziwa, dziko limene iwo kukula chikhalidwe, ali ndi dongosolo lotayirira, imene mipata yopapatiza pakati pa particles munthu. Ndipotu, palibe kanthu ngati capillaries lapansi. Malinga ndi iye madzi umaperekedwa dongosolo muzu ndi chomera amatipatsa chinyezi zofunika ndi mchere wofunika. Komabe, izi madzi njira nthaka adzauka mofulumira asanduke nthunzi. Pofuna kupewa ndondomeko imeneyi, muyenera kuwononga capillaries. Monga cholinga ichi ndi kusunga kwambiri kumasula nthaka. Ndipo nthawizina pali zinthu n'zosiyana, pamene chofunika kumapangitsanso kayendedwe ka madzi capillaries lapansi. Pankhaniyi, nthaka ukatyvayut, motero chiwerengero cha njira yopapatiza ukuwonjezeka. Mu moyo watsiku ndi tsiku, capillary chodabwitsa ntchito mavuto osiyanasiyana. Ntchito matawulo absorbent pepala ndi zopukutira m'manja zimapezeka, ntchito wicks mu nyale palafini ndi zomangamanga - zonse n'zotheka chifukwa cha kukhalapo mu dongosolo awo kwa nthawi yaitali, njira yopapatiza.
