Yog tias koj tab tom mus yos hav zoov, nuv ntses hmo ntuj lossis thaum tus saib xyuas rau qee yam khoom, koj yuav tsum muaj lub tshuab pom yav tsaus ntuj nrog koj. Nrog nws cov kev pab, koj tuaj yeem ua ib zaug tswj xyuas qhov xwm txheej thiab pom cov khoom koj xav tau hauv maub.
Tsim nyog
2 iav daim hlau, zinc sulfide, tooj liab, tin chloride, nyiaj, sib tov ntawm leej faj thiab potassium dichromate, khob iav plooj, SnCl2, qhov cub hluav taws xob, hlau phaj, tester, photoconductor, tweezers, kua roj vanish, hnab looj tes roj hmab, concentrated alkali tov, iav pas nrig, cov siv lead ZnS, cov xov hlau, lub koob yees duab lens, biconvex lens
Cov Lus Qhia
Kauj ruam 1
Tso rau hauv lub khob tsom iav hauv qhov sib tov ntawm leej faj thiab potassium dichromate. Cia lawv zaum li 4 teev thiab kom qhuav.
Kauj ruam 2
Muab cov SnCl2 tso rau hauv ib lub tais thiab tso rau hauv qhov cub. Kho cov iav ntawm qhov deb ntawm 10 cm saum nws.
Kauj ruam 3
Npog lub tais nrog hlau phaj thiab tig rau ntawm qhov cub. Tom qab tos cua sov txog 400 degrees, tshem tawm lub phaj.
Kauj ruam 4
Tos rau qhov chaw conductive tsim thiab tawm hauv lub khob rau hauv qhov cub kom txias. Ntsuam xyuas qhov kev pab them nqi siv tus npaj tes taw.
Kauj ruam 5
Thov cov kua roj vanish rau ib qho ntawm daim hlau (qhov uas tsis yog-xaj ua).
Tom qab ntawv thov cov photosemiconductor. Siv tweezers rau qhov kev txiav txim no, thaum tuav lub phaj ncaj.
Kauj Ruam 6
Hnav cov hnab looj tes, nchuav cov kua tshuaj alkali rau hauv ib lub taub ntim nrog daim hlau thiab sib tov siv lub khob iav.
Kauj Ruam 7
Tom qab 10 feeb, tshem tawm lub phaj thiab yaug nws hauv qab ua dej, ua kom qhuav.
Kauj ruam 8
Muab cov nyiaj tso rau hauv lub khob thiab rov ua cov kauj ruam dhau los, tsuas yog nce qib ntau dua mus rau 900. Siv lub txheej rau lub phaj, qhov twg muaj cov duab ua qauv zoo nkauj.
Kauj Ruam 9
Koj muaj daim iav zaj duab xis. Tom ntej no, npaj lub phosphor siv ZnS. Koj yuav tsum tau txais cov xim tsis muaj kob.
Kauj ruam 10
Sib tov cov kua roj vanish thiab muaju. Ncuav qhov sib tov no dhau ntawm cov plated nyiaj platinum los ua kom tiav txhua qhov chaw. Muab cov phaj conductive tso rau saum toj thiab nias kom nqes kom haum zoo.
Kauj ruam 11
Tom qab thov cov txheej txheem conductive, muab cov xaim xaim rau cov npoo ntawm daim hlau.
Kauj ruam 12
Leem thiab sib dhos ntawm qhov pom kev hmo ntuj siv lub koob yees duab, lub koob yees duab lub lens thiab muab hluav taws xob hauv.
