I-LEEM-10A Imishini Yokuhlola Yezimpawu Ze-PN Junction

Incazelo emfushane:

Isingeniso

Izakhiwo zomzimba ze-semiconductor PN junction zingenye yezinto ezibalulekile eziyisisekelo zefiziksi kanye ne-elekthronikhi. Le divayisi isebenzisa indlela yokuhlola ngokomzimba ukukala ubudlelwano phakathi komsinga wokusabalalisa we-PN junction kanye ne-voltage, ifakazela ukuthi lobu budlelwano bulandela umthetho wokusabalalisa we-exponential, futhi ikala i-Boltzmann constant (esinye se-constants ezibalulekile ku-physics) ngokunembile, okwenza abafundi bakwazi ukufunda indlela entsha yokukala umsinga obuthakathaka. Le divayisi inikeza i-thermostat yokushintshana kwe-heater ukukala ubudlelwano phakathi kwe-PN junction voltage kanye ne-thermodynamic temperature T, ukuze kutholakale ukuzwela kwenzwa, futhi kulinganiswe ukuthola igebe lamandla lezinto ze-silicon ku-0K. Le divayisi izinzile futhi ithembekile, futhi inokuqukethwe okuningi kokuhlola ngokomzimba, umqondo ocacile, ukwakheka kwesakhiwo okunengqondo kanye nemiphumela yokulinganisa okunembile kakhulu. Le divayisi isetshenziswa kakhulu ekuhlolweni ngokomzimba okujwayelekile kanye nasekuhlolweni kocwaningo lokuklama emakolishi nasemanyuvesi.


Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa

1. Ubudlelwano phakathi komsinga wokusabalalisa kwe-PN junction kanye ne-voltage ye-junction buyalinganiswa, futhi lobu budlelwano buzofakazelwa ukuthi bulandela umthetho wokusabalalisa we-exponential ngokucubungula idatha;

2. I-Boltzmann constant ilinganiswa ngokunembe kakhudlwana (Iphutha lizoba ngaphansi kuka-2%);

3. Funda ukusebenzisa i-operational amplifier ukwakha i-current-voltage converter ukukala i-current ebuthakathaka kusukela ku-10-6Kusukela ku-A kuya ku-10-8A;

4. Ubudlelwano phakathi kwe-PN junction voltage kanye nezinga lokushisa buyalinganiswa futhi kubalwa ukuzwela kwe-junction voltage nezinga lokushisa;

5. Cishe ukubala igebe lamandla lezinto ze-semiconductor (silicon) ku-0K.

Izinkomba Zobuchwepheshe

1. Ukunikezwa kukagesi kwe-DC

Ukunikezwa kwamandla kagesi okungaguquki okungu-0-1.5V DC;

Ugesi we-DC ongu-1mA-3mA olungisekayo.

2. Imodyuli yokulinganisa i-LCD

Isilinganiso sesisombululo se-LCD: amaphikseli angu-128×64

Izinkomba ezimbili zedijithali ze-voltage Range: 0-4095mV, Isilinganiso sesisombululo: 1mV

Ibanga: 0-40.95V, Isilinganiso sesisombululo: 0.01V

3. Idivayisi yokuhlola

Yakhiwe nge-amplifier yokusebenza i-LF356, isokhethi yokuxhuma, i-potentiometer enama-turn amaningi, njll. I-TIP31 kanye ne-triode yohlobo lwe-9013 zixhunywe ngaphandle.

4. I-heater

Isifudumezi esilungisekayo sethusi esimile kahle;

Ububanzi bokulawula izinga lokushisa le-thermostat: Izinga lokushisa legumbi lifinyelela ku-80.0℃;

Isilinganiso sokulungiswa kokulawula izinga lokushisa ngu-0.1℃.

5. Imishini yokulinganisa izinga lokushisa

Inzwa yokushisa yedijithali ye-DS18B20
