Kukho iindlela zeshumi elinambini zokulinganisa
Umzimba. Oku kuhlala kwenziwe nge-mercury thermometers. Kodwa ngoku kwintengiso ungayifumana imivimbo ehamba ze, infrared, galaline, elektrone. Cinga ngohlobo oluqhelekileyo lwee-thermometers, siqikelela izibonelelo zabo kwaye
.
I-Mercury Thertometer
Izibonelelo:
Iqondo lobushushu lilinganiswa sisininzi sabantu endleleni. I-thermometer enjalo yiflask yeglasi ene-capillary equkethe iMPUCE. Ngamanye amaxesha le thermometer ibizwa ngokuba yi-Mercury, kuba i-mercury inokuphakama ibe kwinqanaba lokugqibela lokufudumeza kwaye aliwele ngaphandle kokungcangcazela.
Izinto ezingalunganga:
I-Mercury Thercury ithathwa njengeyingozi kakhulu ngenxa ye-mercury, ngaphandle kwento yokuba ibonisa eyona nto ichanekileyo. Kodwa ukuba uyaphula, i-Mercury inokubangela iingxaki ezinkulu. Izibini ze-mercury zinefuthe elibi kwimpilo yabantu.
Yifunde: Yintoni ekufuneka yenziwe ngabazali xa umntwana enobushushu obuphezulu?
I-GallistanTeermometer
Izibonelelo:
Ijongeka ngathi ikhangeleka ngathi yi-thercometer ye-mercury, kodwa enyanisweni ayikho i-mercury ngaphakathi. Endaweni yalo-umxube wezinyithi zolwelo njenge-India, iTin kunye ne-gelium (Gallinstan). Ayinabungozi ebantwini. Ukwahlula kwethemometha enjalo akuyi kwenzakalisa impilo yabantu.
Izinto ezingalunganga:
Kukho ukungaqiniseki okukhulu kwethemometha-kunzima kakhulu ukuyibeka phantsi isalathiso sokulinganisa ubushushu bomzimba. Umxube wensimbi uhamba ngetyhubhu yeglasi enobunzima obukhulu olwahlukileyo kwi-mercury. Kananjalo ukuze ithemometha enjalo ibonise isiphumo esichanekileyo, ufuna ukudinwa ecaleni komzimba. Ukuba le meko ayiqapheli, iqondo lobushushu linokungalunganga.
I-Digital Thermometer
Izibonelelo
Inkangeleko yanamhlanje. I-thermometer enjalo yityhubhu yeplastiki enemiboniso, i-wiring iguqukile kwizindlu. Ibonisa iziphumo zicacile, umgangatho wobushushu udla ngokuthatha imizuzu emi-3 ukuya kwezi-5. Xa kugqityiwe ukulinganiselwa kobushushu, i-beep izandi. Ixabiso lokugqibela lobushushu obulinganiselweyo kwisixhobo siyagcinwa.
ukungancedi
I-elektrometer ye-elektromer inezinto ezimbini ezingalunganga. Iindleko eziphezulu kunye nokubakho kokufumana isiphumo esichanekileyo kunye ne-pirting engagungqiyo emzimbeni. Abantwana abancinci banzima ukuyeka indawo, ngoko ihlala inomxholo othi upost isiphumo esingachanekanga.
I-infrared thermometer
Izibonelelo
I-thermometer ye-infrared ilungele ukulinganisa ubushushu bomzimba kunye nokulinganisa ubushushu obuncinci. I-thermometer enjalo ilungele ukulinganisa ubushushu emntwaneni, kuba akunyanzelekanga ukuba iphazamise, kwaye oku kuphinda kuqinisekiswe ngokulula kunye nokulula. Imilinganiselo ithatha nje imizuzwana nje, kwaye isiphumo sivele kwangoko kwisibonisi. Idatha kwimilinganiselo yobushushu yakutshanje igcinwe.
ukungancedi
Eyona nto iphambili kwi-thermometer enjalo yindleko eziphezulu. Impazamo ekulinganiseni isixhobo esinjalo siphezulu. Isiphumo esichanekileyo ngakumbi, kuyimfuneko ukuba baqhube amanqanaba aliqela. Kubalulekile ukusebenzisa le fowuni kwezinye iindawo zomzimba, njengebubunzi, iWhiskey kunye nendlebe.
Yeyiphi kwezixhobo eziboniswe ziziphumo ezichanekileyo?
Ukuze ufumanise ukuba ingaba i-thercurmomesters ye-therculory yanamhlanje igqithile ngaphezulu, kwenziwa uvavanyo. Elabhoratri, kufakwa isikhongozeli wamanzi, ihekelo ekhethekileyo kunye nesixhobo esasinoxanduva lokusasazwa kwe-iyunifomu yolwelo kwaye kugcinwe iqondo lobushushu. Yayingama-36,2 ° C.
Ngovavanyo, i-Gollin ezininzi yase-Ialine, i-elektrometers ne-elektrometer yathengwa. Ngokweziphumo zamava, kunokutshiwo ukuba iMercury kunye ne-Galin-esemgangathweni ye-thermometers ichazekile. Kwakhona ukufundwa kwe-elektroniki thermometers yajika ichaneke ngokupheleleyo kwaye yayikufuphi nexabiso lokwenyani lobushushu. I-thermometers ye-infrared ayizange ihlangane ngokupheleleyo nomsebenzi.
Ngaba uyathanda ukuba yeyiphi i-thermometer eyenza ukhetho?
I-Mercury Thercury ithathwa njengeyona ichanekileyo kwaye ihluma indalo yonke le thermometers. Kodwa akunakwenzeka ukuphonononga ukuba xa isetyenziswa, isilumkiso esikhulu kubalulekile. Imele igcinwe kwimeko kwindawo apho abantwana baya kufumana khona.
Ukuba ngequbuliso kwabakho imeko apho i-Mercury themometer yaphukile, kungcono ukufuna uncedo kwiingcali kwaye ubone ukuba iibhola ze-Mercury azibonwa. Kubalulekile ukuba ungalibali ukuba i-mercury ayivuyi, kwaye izibini zayo azinakuqatshelwa. Ithermometer eyaphukileyo inokubangela ityhefu yabo bonke abahlali baseflethi.
