Kutentha Kwambiri Kwambiri

Mfundo zazikuluzikulu mpweya wotentha amamvetsetsa ndikugwiritsidwa ntchito popanga zinthu kuchokera ku 1920s. Panthawi ya nkhondo yachiŵiri ya padziko lonse, lusoli linakula mofulumira kuti likhale ndi nthawi yeniyeni yolimbana ndi nthawi yolimbana ndi njira yowonjezera, yodalirika yopangira zipangizo zamagetsi zamphamvu. Posachedwapa, kuyang'ana pa njira zowonongeka bwino ndikugogomezedwa pa kuyendetsa bwino kayendedwe ka khalidwe kwachititsa kuti pakhale kukonzanso kwa teknoloji yopangira muyeso, pamodzi ndi chitukuko choyendetsedwa bwino, chonse cholimba zopatsa mphamvu zotentha.

Kutentha kwachitsulo kumachitika chinthu chogwiritsira ntchito magetsi (osati kwenikweni maginito zitsulo) pamene chinthucho chiyikidwa mu maginito osiyanasiyana. Kutentha kwachitsulo kumachokera ku hysteresis ndi kuwonongeka kwa eddy kwamakono.

Zoyipa za Hysteresis zimachitika ndimaginito chabe monga chitsulo, faifi tambala, ndi ena ochepa. Kutaya kwa Hysteresis kumanena kuti izi zimayambitsidwa chifukwa cha kusamvana pakati pa mamolekyulu pomwe zinthuzo zimakhala ndi maginito koyamba mbali imodzi, kenako mbali inayo. Mamolekyu amatha kuwonedwa ngati maginito ang'onoang'ono omwe amatembenuka ndikusintha kulikonse komwe kuli maginito. Ntchito (mphamvu) imafunika kuti asinthe. Mphamvu imasintha kukhala kutentha. Kuchuluka kwa kagwiritsidwe ntchito ka mphamvu (mphamvu) kumawonjezeka ndi kuchuluka kwakusintha (pafupipafupi).

Zotayika pakadali pano zimachitika mukamtundu uliwonse wamagetsi. Izi zimayambitsa mutu, ngakhale zida zake zilibe maginito omwe amakhala ndi chitsulo ndi chitsulo. Zitsanzo zake ndi zamkuwa, zamkuwa, zotayidwa, zirconium, zosapanga dzimbiri zosapanga dzimbiri, ndi uranium. Mafunde a Eddy ndi mafunde amagetsi omwe amalowetsedwa ndimachitidwe osinthira zinthuzo. Monga momwe dzina lawo limatanthawuzira, amawoneka kuti amayenda mozungulira mozungulira pamiyala yolimba kwambiri. Zotayika zamakono za Eddy ndizofunikira kwambiri kuposa kutaya kwa hysteresis pakuwonjezera kutentha. Dziwani kuti kutenthetsa kutentha kumagwiritsidwa ntchito pazinthu zopanda maginito, pomwe palibe zotayika za hysteresis zomwe zimachitika.

Kutentha kwachitsulo kuti kuumitsa, kuyimitsa, kusungunuka, kapena zolinga zina zomwe zimafuna kutentha pamwamba pa Curie kutentha, sitingadalire hysteresis. Chitsulo chimataya maginito ake pamwamba pa kutentha kwake. Pamene chitsulo chimatenthedwa pansi pa Curie mfundo, zopereka za hysteresis ndizochepa kwambiri moti zimatha kunyalanyazidwa. Kwa zofunikira zonse, I2R ya mazira a mphepo ndi njira yokha yomwe magetsi amagwiritsira ntchito kutentha kuti apange kutentha.

Zinthu ziwiri zofunika kuti mpweya wabwino uzitha kuchitika:

  • Kusintha kwa maginito
  • Zida zamagetsi zimayikidwa mu maginito
zofunikira zowonjezera kutentha
zofunikira zowonjezera kutentha
