LEEM-10A Midziyo Yekuyedza yePN Junction Hunhu Mufananidzo Wakaratidzwa
  • LEEM-10A Chishandiso Chekuyedza chePN Junction Hunhu

LEEM-10A Chishandiso Chekuyedza chePN Junction Hunhu

Tsananguro pfupi:

Nhanganyaya

Hunhu hwemuviri hwe semiconductor PN junction ndeimwe yezvinhu zvakakosha zviri mufizikisi nemagetsi. Mudziyo uyu unoshandisa nzira yekuedza panyama kuyera hukama huripo pakati pe diffusion current ye PN junction ne voltage, zvinoratidza kuti hukama uhwu hunotevera exponential distribution law, uye unoyera Boltzmann constant (imwe ye constants inokosha mu fizikisi) zvakanyatsonaka, izvo zvinoita kuti vadzidzi vadzidze nzira itsva yekuyera weak current. Mudziyo uyu unopa heater alternating temperature thermostat yekuyera hukama huripo pakati pe PN junction voltage ne thermodynamic temperature T, kuitira kuti uwane sensitivity ye sensor, uye inenge yekuwana energy gap yezvinhu zve silicon pa 0K. Mudziyo uyu wakasimba uye wakavimbika, uye une zvakawanda zviri mukati me physical experiment, pfungwa yakajeka, structural design inonzwisisika uye high-acurate measurements. Mudziyo uyu unonyanya kushandiswa mu general physical experiments uye design research experiments mumakoreji nemayunivhesiti.


Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Kuedza

1. Hukama huri pakati pePN junction diffusion current nejunction voltage hunoyerwa, uye hukama uhwu hunofanira kuratidzwa kuti hunotevera mutemo wekugoverwa kweexponential kuburikidza nekugadzirisa data;

2. Boltzmann constant inoyerwa nemazvo (Chikanganiso chinofanira kunge chiri pasi pe2%);

3. Dzidza kushandisa operational amplifier kugadzira current-voltage converter kuyera weak current kubva pa10-6Kubva A kusvika 10-8A;

4. Hukama huripo pakati pePN junction voltage netembiricha hunoyerwa uye kunzwisiswa kwejunction voltage netembiricha kunoverengerwa;

5. Inenge nguva yekuverenga mukaha wesimba wezvinhu zve semiconductor (silicon) pa0K.

MaIndekisi eUnyanzvi

1. DC magetsi

Simba rinogadziriswa re 0-1.5V DC;

Simba remagetsi re1mA-3mA DC rinogadziriswa.

2. Module yekuyera LCD

Chiyero cheLCD resolution: 128×64 pixels

Zviratidzo zviviri zvedhijitari zvemagetsi Range: 0-4095mV, Resolution ratio: 1mV

Range: 0-40.95V, Chiyero chekugadzirisa: 0.01V

3. Chishandiso chekuyedza

Inoumbwa ne operational amplifier LF356, connector socket, multi-turn potentiometer, nezvimwewo. TIP31 ne type 9013 triode zvakabatana kunze.

4. Chitofu

Chitofu chinogadziriswa nemhangura chinoomesa;

Tembiricha yekudzora tembiricha yethermostat: Tembiricha yemukamuri kusvika 80.0℃;

Chiyero chekugadzirisa tembiricha 0.1℃.

5. Midziyo yekuyera tembiricha

Sensor yekupisa yedhijitari yeDS18B20

  • Yakapfuura:
  • Zvinotevera:
    • Nyora meseji yako pano woitumira kwatiri
