I-LEEM-10A I-Apparatus Yokuhlola Yezici Ze-PN Junction

Incazelo emfushane:

Isingeniso

Izakhiwo ezibonakalayo ze-semiconductor PN junction zingenye yezinto ezibalulekile eziqukethwe ku-physics ne-electronics.Lesi sisetshenziswa sisebenzisa indlela yokuhlola ngokomzimba ukukala ukuhlobana phakathi kwamandla okusabalalisa i-PN junction kanye ne-voltage, kufakazela ukuthi lokhu kuhlobana kulandela umthetho wokusabalalisa umchazi, futhi kukala ukungaguquki kwe-Boltzmann (okukodwa kokungaguquki okubalulekile ku-physics) ngokunembe kakhudlwana, okwenza abafundi bafunde indlela entsha yokukala amandla amanje abuthakathaka.Le mishini ihlinzeka nge-thermostat ye-heater eshintshashintshayo yezinga lokushisa ukukala ukuhlobana phakathi kwe-PN junction voltage kanye nezinga lokushisa le-thermodynamic T, ukuze kutholwe ukuzwela kwenzwa, futhi kulinganiselwa ukuthola igebe lamandla lento ye-silicon ku-0K.Le mishini izinzile futhi ithembekile, futhi inokuqukethwe okuningi kokuhlolwa ngokomzimba, umqondo ocacile, idizayini yesakhiwo enengqondo kanye nemiphumela yokulinganisa yokunemba okuphezulu.Lesi sisetshenziswa sisetshenziswa kakhulu ekuhloleni ngokomzimba okujwayelekile kanye nokuhlolwa kocwaningo lokuklama emakolishi nasemanyuvesi.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izivivinyo

1. Ubudlelwano phakathi kwe-PN junction diffusion current kanye ne-junction voltage kuyalinganiswa, futhi lokhu kuhlobana kuzofakazelwa njengokulandela umthetho wokusabalalisa okuchazile ngokucubungula idatha;

2. I-Boltzmann constant ikalwa ngokunembe kakhulu(Iphutha lizoba ngaphansi kuka-2%);

3. Funda ukusebenzisa i-amplifier ukuze wakhe isiguquli se-voltage yamanje ukuze ulinganise amandla amanje abuthakathaka ukusuka ku-10.-6A kuya ku-10-8A;

4. Ukuhlobana phakathi kwe-PN junction voltage kanye nezinga lokushisa kuyalinganiswa futhi ukuzwela kwe-voltage ye-junction nezinga lokushisa kuyabalwa;

5. Cishe ukubala igebe lamandla le-semiconductor (silicon) into engu-0K.

Izinkomba Zobuchwepheshe

1. Ukunikezwa kwamandla kwe-DC

Ugesi oshintshwayo ongu-0-1.5V DC;

Ukunikezwa kwamandla kwe-1mA-3mA DC okulungisekayo.

2. Imojula yokulinganisa ye-LCD

Isilinganiso sokulungiswa kwe-LCD: 128×64 pixels

Izinkomba ezimbili zedijithali ze-voltage Range: 0-4095mV, Resolution ratio: 1mV

Ububanzi: 0-40.95V, Isilinganiso sokulungiswa: 0.01V

3. Idivayisi yokuhlola

Yakhiwe nge-amplifier yokusebenza i-LF356, isokhethi yesixhumi, i-multi-turn potentiometer, njll. I-TIP31 kanye nohlobo lwe-9013 triode zixhumeke ngaphandle.

4. I-heater

Yomisa kahle heater yethusi adjustable;

Ibanga lokulawula izinga lokushisa le-thermostat: Izinga lokushisa legumbi ukuya ku-80.0℃;

Isilinganiso sokulungiswa sokulawula izinga lokushisa ngu-0.1℃.

5. Imishini yokulinganisa izinga lokushisa

Inzwa yokushisa yedijithali ye-DS18B20
