LEEM-10 Zida Zoyesera za PN Junction Characteristics
Zoyesera
1. Pa kutentha komweko, yesani mawonekedwe a kutsogolo kwa volt-ampere a mphambano ya PN ndikuwerengera nthawi zonse za Boltzmann;
2. Patsogolo pakali pano ndimakhalabe wosasinthika, VT yokhotakhota ya voteji kutsogolo kwa PN mphambano ndi mapu, tilinazo amawerengeredwa, ndi gulu kusiyana m'lifupi mwa kuyeza PN mphambano zakuthupi akuyerekeza;
3. Kugwiritsa ntchito kuyesa: gwiritsani ntchito mphambano ya PN yoperekedwa kuti muyese kutentha kosadziwika;
4. Kuyesera kwatsopano: Malingana ndi deta yoyesera, yerekezerani kuti machulukitsidwe amakono Ndi a PN junction.
5. Kuyesera kofufuza: Yang'anani mphamvu ya kukula kwa gulu lamakono.
Waukulu luso magawo
1. Mitundu yosiyanasiyana ya PN yokhala ndi ma CD, kuphatikizapo machubu a silicon, machubu a germanium, NPN transistors, ndi zina zotero;
2. Zomwe zilipo panopa ndi 10nA~1mA, zosinthika m'magawo a 4, kusintha kwabwino: osachepera 1nA, magetsi oyendetsa galimoto.
Pafupifupi 5V, kulumpha mawu ≤ 1 mawu/mphindi;
3. Odzipereka kopitilira muyeso-mkulu kukana 4-1 / 2 digito voltmeter digito, milingo iwiri ya kukana mkati: 10MΩ, kopitilira muyeso-mkulu kukana mlingo (wamkulu kuposa 1GΩ), muyeso osiyanasiyana: 0~2V, kusamvana: 0.1mV;kusatsimikizika muyeso: 0.1% ± 2 mawu.
4. Kutentha koyesera: kutentha kwa chipinda>99℃, thermometer ya digito: 0~100℃, kusamvana 0.1℃;
5. Kuphatikiza chotenthetsera chamagetsi, botolo la Dewar ndi beaker.
