Enyanisweni, kuyimfuneko ukutshintsha i-earmuffs ye-ear thermometers. Ukutshintsha i-earmuffs kunokuthintela usulelo olunqamlezayo. Iithemometha zendlebe ezineendlebe zikwafaneleke kakhulu kwiiyunithi zonyango, iindawo zikawonke-wonke, kunye neentsapho ezineemfuno eziphezulu zococeko. Ngoku ndiza kukuxelela ngeendlebe. Kufuneka zitshintshwe kangaphi izinto ezivala iindlebe zompu oshushu? Abazali bafanele bawuqonde lo mba ngokweenkcukacha. Kufuneka itshintshwe kangaphi ithemometha endlebeni?
Okokuqala, i-earmuff enye ingasetyenziselwa amaxesha angama-6-8, kwaye akukho mfuneko yokuyitshintsha ngexesha, elichithwa kakhulu; abantu abohlukeneyo bacebisa ukusebenzisa ii-earmuffs ezahlukeneyo, ezicocekileyo nezikhethekileyo. Sula i-earmuffs ngotywala kunye nekotoni ukwandisa ukuphindaphinda kokusebenzisa i-earmuffs.
Okwesibini, kukho iintlobo ezi-2 ze-earmuffs: uhlobo lwe-earmuff oluphindaphindiweyo: emva kokusetyenziswa ngalunye, sula i-earmuffs nge-cotton swab efakwe kwi-alcohol yonyango.
I-advanteji kukuba i-earmuffs inokusetyenziswa ngokuphindaphindiweyo, kodwa izinto ezingeloncedo zezi: ①Ukuba i-earmuffs ibambekile ngegrisi okanye ubumdaka, ukuchaneka komlinganiselo olandelayo wobushushu kuya kuchaphazeleka; ②Iindlebe ziya kunxitywa okanye zikrwelwe emva kokosulwa ngokuphindaphindiweyo. Umkhondo, oya kuchaphazela ukuchaneka komlinganiselo wokushisa; ③Kuthatha ixesha elide (malunga ne-5min) ukwenza umlinganiselo wesibini emva kokucima utywala bezonyango, ngoko ke imilinganiselo emininzi ayinakwenziwa ngexesha elifutshane;
Okwesithathu, iindlebe ezilahlwayo: tshintsha ii-earmuffs ngokukhawuleza emva kokusetyenziswa ngakunye. Iingenelo zayo zezi: ①Akukho mfuneko yakuzikhathaza malunga nokungachaneki komlinganiselo wobushushu ngenxa yokuguga okanye ukungcola kweendlebe; ②Umlinganiselo wesibini unokwenziwa i-15s emva komlinganiselo wokuqala. Ukungalungi kuphela kukuba i-earmuffs ehambelanayo zizinto ezisetyenziswayo.
Okwesine, kukho olunye uhlobo lwe-thermometer yendlebe ngaphandle kwee-earmuffs: olu hlobo lwe-thermometer yendlebe luya kuhlasela inkqubo ye-optical path (waveguide) ekusetyenzisweni kwansuku zonke, okuya kubangela ukulinganisa ubushushu obusisigxina kwi-thermometer yendlebe. Olu hlobo lwethemometha yendlebe luyilwe ngabavelisi abathile ukujongana nombono wokusetyenziswa kwabantu baseTshayina. Akukho mfuneko yokutshintsha i-earmuffs. Inzuzo kukuba ifanelekile. Ukungalungi kukuba iziphumo zokulinganisa azinakuqinisekiswa ukuba zichanekile. Ngoko ke, ii-earphones ezivela kwiimpawu zehlabathi ezifana ne-barun, i-omron, njl.
Izinto eziluncedo zethermometer yendlebe
1. Ukukhawuleza: Logama nje umzuzwana omnye okanye ngaphantsi, ubushushu bomzimba obuchanekileyo bunokulinganiswa ukusuka endlebeni.
Xa umntwana eqhubeka nomkhuhlane, unokulinganiswa nangaliphi na ixesha ukuba wazi ngokukhawuleza utshintsho kwiqondo lokushisa lomzimba.
2. Ethambileyo: Ikhululekile ukuyisebenzisa, ithambile kangangokuba umntwana akanayo nayiphi na imvakalelo engathandekiyo, naxa elinganisa ngelixa elele, akukho mfuneko yakukhathazeka ngokuvusa umntwana?
3. Ukuchaneka: Khangela ubushushu be-infrared obukhutshwa yi-membrane ye-tympanic kunye nezicubu ezijikelezileyo, kwaye usebenzise i-chip ye-microcomputer eyakhelweyo ukubala ngokukhawuleza ubushushu bomzimba obuchanekileyo, kwaye uyibonise kwindawo enye yedesimali, exazulula ubunzima bokuqonda imveli. isikali se-thermometer.
Ithemomitha entsha yesibini inokuskena ubushushu bomzimba amaxesha asibhozo ngomzuzwana omnye kwaye ibonise ubushushu obuphezulu bokufunda, obuqinisekisa ukuchaneka komlinganiselo.
4. Ukhuseleko: Ithemometha yemveli yemercury kulula ukuyiqhekeza xa ibonakaliswe kubushushu okanye ibekwe ngendlela engafanelekanga, kwaye i-mercury iyakhutshwa. Ukuba i-thermometer ye-mercury iphula emzimbeni womntu, umphunga we-mercury uya kuthatyathwa ngumzimba womntu.
Kuye kwafunyaniswa ukuba ukuchanabeka kwabantwana ixesha elide kwimekyuri kuya kubangela umonakalo kwimithambo-luvo, yaye abafazi abakhulelweyo abatya iintlanzi ezinemekyuri baya kubangela umonakalo kusana olungekazalwa. Ngaphezu koko, ixesha lokulinganisa lide, kwaye i-thermometer yendlebe inqoba iintsilelo ze-mercury thermometers ezingentla.
