LADP-15 Cov Khoom Siv Rau Kev Txheeb Xyuas Planck's Constant (Software Xaiv Tau)

Kev sim

1. Ntsuas qhov hluav taws xob txiav tawm thiab xam kom tau txais Planck tus nqi tas li.
2, Ntsuas qhov photocurrent ntawm lub phototube thiab ua qhov kev sim ntawm cov nyhuv photoelectric.

Cov kev tsis tseem ceeb
1, microcurrent ntau yam: 10-6 ~ 10-13A tag nrho ntawm rau cov ntaub ntawv, peb thiab ib nrab cov zaub digital, xoom drift ≤ 2 lo lus / feeb.
2, thaum tig lub diaphragm, yuav tsis tsav lub lim xim, ob qho tuaj yeem tig tau ywj pheej, tsis muaj kev cuam tshuam rau ib leeg, xav tias lub teeb, yooj yim siv, thiab zam kev ncaj qha lub teeb phototube.
3, photocell: muab tso rau hauv lub thawv tsaus ntuj photocell, ua haujlwm fais fab ntau yam: -2V ~ + 2V; -2V ~ + 30V
ob cov ntaub ntawv, nrog kev kho kom zoo; kev ruaj khov ≤ 0.1%.
4, phototube spectral teb ntau yam: 340 ~ 700nm, cathode rhiab heev ≥ 1μA, tsaus nti tam sim no <2 × 10-12A, anode: nickel nplhaib.
5, lim xim: 365.0nm; 404.7nm; 435.8nm; 546.1nm; 578.0nm.
6, suav nrog lub teeb mercury siab thiab lub teeb mercury fais fab mov, lub teeb mercury fais fab 50W.
7, qhov yuam kev ntawm h tus nqi thiab theoretical tus nqi: ≤ 3%.
8, hom microcomputer tuaj yeem txuas nrog USB interface rau lub khoos phis tawj rau kev sim, tsis muaj khoos phis tawj.
