(Incazelo efingqiwe)Sebenzisa inzwa ukukala i-coefficient yokucindezela okuhlobene komoya; nqamula inzwa kupompo ye-vacuum, futhi ufunde i-voltage ephumayo engu-U0 yenzwa ngalesi sikhathi. I-U. ibangelwa ukukhukhuleka kwephoyinti lenzwa eliyiziro nokuzwela ngokushintsha kwezinga lokushisa.
Sebenzisa inzwa ukukala i-coefficient yokucindezela okuhlobene komoya; nqamula inzwa kupompo ye-vacuum, futhi ufunde i-voltage ephumayo engu-U0 yenzwa ngalesi sikhathi. I-U. ibangelwa ukukhukhuleka kwephoyinti lenzwa eliyiziro nokuzwela ngokushintsha kwezinga lokushisa. Susa i-Um ku-U., bese uqhathanisa umehluko nengcindezi yomoya ukuze uthole isilinganiso phakathi kwevelu ye-voltage nevelu yokucindezela komkhathi, okungukuthi, i-Kp. Inqubo yokulinganisa iphela lapha, bese iqala ngokusemthethweni: i-voltage yokufaka ingu-5.011V, i-vacuum degree isuka ku-Shintsha isuka ku-100 iye ku-20, ne-5 njengeyunithi yokushintsha. Linganisa inani le-coefficient yokucindezela komoya elihambisana ne-vacuum degree ngayinye (Qaphela: Inani le-coefficient yokucindezela komoya eliboniswe kuthebula lilungisiwe ngokuthi v/V=0.02 ukuze kuqedwe ushintsho kuvolumu yebhamuza lengilazi kanye nezinga lokushisa elingalingani igesi emhubheni Iphutha elidalekile). Kungabonwa kudatha esethebulani ukuthi inani elilinganisiwe le-coefficient yomfutho womoya ohlobene lilokhu likhuphuka ngokuncipha kwedigri ye-vacuum futhi lichezuka kakhulu kunani layo langempela. Ubudlelwano phakathi kwalezi zinguquko ezimbili buyaboniswa.
Izinga le-vacuum () i-coefficient yokucindezela okuhlobene yomoya. Izinga le-vacuum () i-coefficient yokucindezela okuhlobene yomoya. Izinga le-vacuum () i-coefficient yokucindezela okuhlobene yomoya. I-voltage yokufaka iyashintshwa isuka ku-2V iye ku-9V. Umthelela wedigri ye-vacuum kunani elilinganisiwe le-coefficient yokucindezela okuhlobene yomoya ibonisa ithrendi efanayo. . Isibonelo: uma i-voltage yokufaka ingu-8.005V, amanani akaliwe wedigri ye-vacuum kanye ne-coefficient yomfutho womoya ohlobene aboniswa kuThebula 2. Umthelela wedigri ye-vacuum ku-coefficient yokucindezela okuhlobene komoya njengoba kubonisiwe.
Idigri yevacuum () idigri ye-vacuum yesihlobo somoya () idigri ye-vacuum yengcindezi ehlobene komoya () i-coefficient yomoya ehlobene nomoya ingafinyelela inani lapho idigri ye-vacuum ingu-100, futhi lapho i-voltage yokufaka ingu-8.005V, idigri ye-vacuum iqhathaniswa ne-vacuum degree. I-coefficient yokucindezela kwesihlobo somoya Ukuhlolwa okufanayo kwenziwa kwezinye izinsimbi elabhorethri, futhi kwatholakala imiphumela efanayo. Ukuze kuncishiswe iphutha elibangelwe inkinga yokumpompa i-vacuum, inani elilinganisiwe lomfutho womoya ohlobene lingaphindaphindwa ngevacuum ehambisanayo Izinga lokulungiswa kwemiphumela yokuhlola. Thatha idigri ye-vacuum engu-95 njengesibonelo ukuze ubonise: idigri ye-vacuum ithinta ngokuqondile i-U. Uma i-vacuum degree ingu-95, isinyathelo ngemva kokuhlukanisa ngo-95 inqubo yokudweba umdwebo we-PT ukuze uthole umthambeka (i-slope isihlobo I-coefficient yokucindezela komoya). Njengoba i-slope = A'/AT, i-slope kanye 'nemigqa, inhliziyo ttX 95 ingaguqulwa ukuze iphindaphinde ngokuqondile umthambeka ngo-95, ngoba u-P. wokunqamula umugqa ku-eksisi ye-Y ushintsha kancane kakhulu, can ngqo Inani le-coefficient yokucindezela komoya elitholiwe liphindaphindwa ngo-95 ukuze kulungiswe iphutha elibangelwe ivacuum enganele. Kafushane, ukuphindaphinda inani le-coefficient yomfutho womoya elihlobene elitholiwe ngezinga elihambisanayo le-vacuum kungalungiswa ngenxa ye-vacuum enganele. Iphutha. Isibonelo, i-voltage yokufaka ingu-5.011V, i-vacuum degree ingu-95, futhi inani elilinganisiwe lomfutho womoya ohlobene ngu-0.0038899. Iphutha elihlobene phakathi kwaleli nani nenani langempela ngu-6.28. Uma leli nani liphindaphindwa nge-vacuum degree, lingu-0.0038899X0. 95=0.0036954, iphutha elihlobene phakathi kwevelu elungisiwe kanye nenani langempela lehliselwe ku-0.97. Lesi siphetho singaba ukulungiswa okuhle emiphumeleni yokuhlola lapho idigri ye-vacuum ingekho phansi kakhulu. Uma idigri ye-vacuum iphansi kakhulu, imiphumela ehlukahlukene Umthelela wezici emiphumeleni yokuhlola usobala kakhulu. Ukulungisa kalula idigri ye-vacuum akukwazi ukuthola imiphumela yokuhlola enembile. Kodwa-ke, ngokuvamile, ipompo ye-vacuum elabhorethri ngeke ibe ne-vacuum ephansi kakhulu. Ngakho-ke, ezivivinyweni zansuku zonke zabafundi, lesi siphetho Iphutha elibangelwa i-vacuum enganele lingalungiswa kahle.
Kusukela engxoxweni engenhla, kungaphethwa ngokuthi lapho i-vacuum degree yephampu yevacuum iphansi, likhulu inani le-coefficient yomoya ohlobene elinganiswa ukuhlolwa, futhi yilapho ichezuka kakhulu kunani layo langempela elingu-0.00366K-1. Ushintsho lwevelu elinganisiwe ye-coefficient yokucindezela okuhlobene komoya luyahlukahluka nezinga le-vacuum Iyakhuphuka futhi yehla ngokuqhubekayo, okubonisa ubudlelwano bejika nomthambeka oncipha kancane kancane phakathi kwakho kokubili. Ukuhlolwa kungalungisa imiphumela yokuhlolwa ngokuphindaphinda i-coefficient yokugcina elinganisiwe yokucindezela komoya ngevelu yayo yokuvala ehambisanayo.
