(Inkcazo yesishwankathelo)Sebenzisa inzwa yokulinganisa i-coefficient yoxinzelelo lomoya; qhawula inzwa kwimpompo ye-vacuum, kwaye ufunde i-voltage ye-output U0 ye-sensor ngeli xesha. I-U. ibangelwa yi-drift ye-zero point ye-sensor kunye novakalelo kunye nokutshintsha kweqondo lokushisa.
Sebenzisa inzwa yokulinganisa i-coefficient yoxinzelelo lomoya; qhawula inzwa kwimpompo ye-vacuum, kwaye ufunde i-voltage ye-output U0 ye-sensor ngeli xesha. I-U. ibangelwa yi-drift ye-zero point ye-sensor kunye novakalelo kunye nokutshintsha kweqondo lokushisa. Thabatha u-Um ukusuka e-U., kwaye uthelekise umahluko kunye noxinzelelo lwe-atmospheri ukuze ufumane umlinganiselo phakathi kwexabiso lombane kunye nexabiso loxinzelelo lwe-atmospheric, oko kukuthi, i-Kp. inkqubo yokulinganisa iphela apha, kwaye iqala ngokusemthethweni: i-voltage yegalelo yi-5.011V, idigri ye-vacuum ivela kwi-Tshintsho ukusuka kwi-100 ukuya kwi-20, kunye ne-5 njengeyunithi yokutshintsha. Ukulinganisa ixabiso lomlinganiso woxinzelelo lomoya ohambelana neqondo ngalinye le-vacuum (Qaphela: Ixabiso lomlinganiso woxinzelelo lomoya oboniswe kwitheyibhile lilungiswe nge-v/V=0.02 ukuphelisa utshintsho kumthamo weqamza leglasi kunye nobushushu obungalinganiyo irhasi kumbhobho Impazamo ebangele). Inokubonwa kwidatha ekwitheyibhile ukuba ixabiso elilinganisiweyo lomlinganiso woxinzelelo lomoya lihlala likhula ngokuhla kweqondo lokufunxa kwaye litenxa ngakumbi nangakumbi kwixabiso layo lokwenyani. Ubudlelwane phakathi kwezi nguqu zimbini bubonisiwe.
Iqondo levacuum () umlinganiselo woxinzelelo ohambelana nomoya. Iqondo levacuum () umlinganiselo woxinzelelo ohambelana nomoya. Iqondo levacuum () umlinganiselo woxinzelelo ohambelana nomoya. Igalelo lombane litshintshile ukusuka kwi-2V ukuya kwi-9V. Impembelelo yesidanga se-vacuum kwixabiso elilinganisiweyo le-coefficient yoxinzelelo lwe-air ibonisa indlela efanayo. . Umzekelo: xa igalelo lombane liyi-8.005V, amaxabiso alinganisiweyo eqondo le-vacuum kunye ne-coefficient yoxinzelelo lomoya ehambelanayo iboniswe kwiThebhile 2.
Vacuum degree () isidanga somoya esihambelana noxinzelelo lomlinganiso weqondo lokuvala isidanga () isidanga somoya esihambelana noxinzelelo lwe-vacuum () isidanga somoya esinxulumene noxinzelelo sinokufikelela kwixabiso xa isidanga se-vacuum ili-100, kwaye xa amandla ombane ayi-8.005V, idigri yevacuum vs. I-coefficient yoxinzelelo lwe-air Uvavanyo olufanayo lwenziwa kwezinye izixhobo kwibhubhoratri, kwaye iziphumo ezifanayo zafunyanwa. Ukuze kuncitshiswe impazamo ebangelwa yingxaki yokupompa ivacuum, ixabiso elilinganisiweyo loxinzelelo lomoya linokuphinda-phindwe nge-vacuum ehambelanayo Iqondo lokulungiswa kweziphumo zovavanyo. Thatha idigri ye-vacuum ye-95 njengomzekelo ukubonisa: idigri ye-vacuum ichaphazela ngqo i-U. Xa i-degree ye-vacuum i-95, inyathelo emva kokwahlula ngo-95 yinkqubo yokuzoba umzobo we-PT ukufumana i-slope (i-slope isihlobo i-coefficient yoxinzelelo lomoya). Ukusukela ukuthambeka = A'/AT, ithambeka kunye 'zingumgca, intliziyo ttX 95 inokuguqulwa ukuphinda-phinda ngokuthe ngqo ithambeka ngo-95, kuba ucango lwe-P. lomgca kwi-Y axis itshintsha kancinane kakhulu, ukuze wena ingakwazi ngokuthe ngqo Ixabiso elifunyenweyo loxinzelelo lomoya liphindaphindwa ngo-95 ukulungisa impazamo ebangelwa yi-vacuum engonelanga. Isishwankathelo, ukuphindaphinda ixabiso le-coefficient yoxinzelelo lomoya olufunyenweyo ngeqondo elihambelanayo le-vacuum kunokulungiswa ngenxa yokungonelanga kwe-vacuum. Impazamo. Ngokomzekelo, i-voltage yegalelo yi-5.011V, i-vacuum degree yi-95, kunye nexabiso le-coefficient ye-coefficient yomoya olinganisiweyo ngu-0.0038899. Impazamo enxulumene neli xabiso kunye nexabiso lokwenyani ngu-6.28. Ukuba eli xabiso liphindwe ngeqondo le-vacuum, yi-0.0038899X0. 95=0.0036954, imposiso ehambelanayo phakathi kwexabiso elilungisiweyo kunye nexabiso lokwenyani liyancitshiswa ukuya ku-0.97. Esi sigqibo sinokuba lulungiso olulungileyo kwiziphumo zovavanyo xa idigri yevacuum ingekho phantsi kakhulu. Xa idigri yevacuum iphantsi kakhulu, iziphumo ezahlukeneyo Impembelelo yezinto kwiziphumo zovavanyo ibonakala ngakumbi. Ukulungisa nje idigri yevacuum akukwazi ukufumana iziphumo zovavanyo ezichanekileyo. Nangona kunjalo, ngokubanzi, impompo yokucoca kwilabhoratri ayiyi kuba ne-vacuum ephantsi kakhulu. Ngoko ke, kwiimvavanyo zabafundi bemihla ngemihla, esi sigqibo Impazamo ebangelwa yi-vacuum enganeleyo inokulungiswa kakuhle.
Ukususela kule ngxoxo ingentla, kunokugqitywa ukuba iqondo elisezantsi le-vacuum yempompo yokufunxa, ixabiso elikhulu le-coefficient yomoya ohambelanayo olinganiswe luvavanyo, kwaye ngakumbi itenxa kwixabiso layo lokwenyani 0.00366K-1. Utshintsho lwexabiso elilinganisiweyo le-coefficient yoxinzelelo lwe-air ihluka kunye neqondo le-vacuum Ukunyuka kunye nokunciphisa ngokuqhubekayo, kubonisa ubudlelwane begophe kunye ne-slope esihla ngokuthe ngcembe phakathi kwezi zibini. Uvavanyo lunokulungisa iziphumo zovavanyo ngokuphinda-phinda icoefficient yoxinzelelo lomoya olulinganisiweyo lokugqibela ngexabiso elihambelanayo levacuum.
