Mea Hana LADP-15 no ka Hoʻoholo ʻana i ke Kūlana o Planck (Koho Polokalamu)

Nā hoʻokolohua

1, E ana i ka volta ʻoki a helu e loaʻa ai ke kūpaʻa o Planck.
2, E ana i ke kahe kiʻi o ka phototube a hana i ka hoʻokolohua o ka hopena photoelectric.

Nā palena loea nui
1, ka laulā o ka microcurrent: 10-6 ~ 10-13A he ʻeono mau faila, ʻekolu a me ka hapa hōʻike kikohoʻe, ʻaʻohe holo ʻana ≤ 2 mau huaʻōlelo / min.
2, i ka wā e hoʻohuli ai i ka diaphragm, ʻaʻole e hoʻokele i ka kānana kala, hiki ke hoʻohuli ʻia nā mea ʻelua me ke kūʻokoʻa, ʻaʻohe mana o kekahi i kekahi, e māmā ka manaʻo, maʻalahi e hoʻohana, a pale i ka phototube māmā pololei.
3, photocell: waiho ʻia i loko o ka pahu pouli photocell, ka mana hana: -2V ~ + 2V; -2V ~ + 30V
ʻelua mau faila, me ka hoʻonohonoho maikaʻi ʻana; kūpaʻa ≤ 0.1%.
4, ka laulā pane spectral o ka phototube: 340 ~ 700nm, ka ʻike cathode ≥ 1μA, ke au pouli <2 × 10-12A, anode: apo nickel.
5, kānana kala: 365.0nm; 404.7nm; 435.8nm; 546.1nm; 578.0nm.
6, me ke kukui mercury kiʻekiʻe a me ka lako mana o ke kukui mercury, ʻo ka mana o ke kukui mercury he 50W.
7, ka hewa o ka waiwai h a me ka waiwai kumumanaʻo: ≤ 3%.
8, hiki ke hoʻopili ʻia ke ʻano microcomputer i ke kamepiula e ka USB interface no nā hoʻokolohua, me ka ʻole o ke kamepiula.
