• rau cov kev ua ub no ntawm kev ruaj ntseg zov, tub ceev xwm tub ceev xwm, tub rog thiab cov tsav tsheb uas feem ntau muaj los kho txoj kev cov khoom nyob rau hauv cov teb tsaus;
• rau cov neeg uas nyiam kom muab cov duab los yog tua video koob yees duab cov tsiaj qus thaum hmo ntuj.

Peb yuav tsum tau pom thaum tsaus ntuj tsom iav rau kev yos hav zoov, nuv ntses thiab tourism. Hnav lawv, koj yuav tsum tau sai sai sib sau ua ke nyob rau hauv qhov tsaus ntuj nti ntoo rau kindling ib tug tua hluav taws, dhau dawb do los ntawm cov thicket thiab tsis tau poob rau hauv nws, tsis txhob ntshaus rau ib tsob ntoo cov hauv paus hniav thiab poob mus rau hauv ib lub qhov. Thiab hais tias yog cia li lub ntsiab pab nta ntawm no ntaus ntawv. Cov no muaj xws li ib tug lossis loj ntau yam ntawm lwm yam nuances.
Hmo ntuj pom kev tsom iav yuav tau muas ntawm lub khw, tab sis yog, lawv yog heev kim. Ib lwm cov tshuaj - ua rau koj tus kheej nyob rau hauv tsev. Sim nco koj paub txog Science News for KIDS thiab physics, thiab ces koj yuav yooj yim rau to taub yuav ua li cas yuav ua rau lawv tus kheej hmo ntuj-lub zeem muag tsom iav. Nrhiav tej phau ntawv, nyeem cov ntaub ntawv, npaj.

Kauj ruam yog kauj ruam qhia
Siv ob lub khob daim hlau thiab raus lawv nyob rau hauv kev daws ntawm poov tshuaj dichromate thiab sulfuric acid (hais txog 4 teev). Ces qhuav lub iav thiab txhim kho lawv nyob rau lub iav khob ntawm ib qhov siab ntawm tsis tsawg tshaj li 10 cm (nyob rau hauv lub peev xwm koj yuav tsum muab lub tin chloride). Tam sim no tag nrho cov no qhov chaw nyob rau hauv ib tug muffle rauv. Nyob rau hauv lub pre-nteg khob phaj ntawm hlau.
Preheat qhov cub rau ib tug kub ntawm tsawg kawg yog 470 degrees Celsius. Sai sai tshem tawm cov phaj. Tam sim no saib kom zoo zoo rau cov kev hloov uas tshwm sim nrog qhov rais. Lawv yuav maj mam them los ntawm ib tug nyias zaj duab xis, ib tug conductive tam sim no.
Xa tawm hauv qhov cub, cia txias tsom iav. Thov mus rau sab qhov rais, qhov twg tsis conductive zaj duab xis, lacquer thiab qis iav tiakarbomida thiab txhuas acetate. Ces ncuav lub concentrate no alkali, maj mam muab stirring lub resultant kua. Tom qab 15 feeb, ua tib zoo tshem tawm cov iav los ntawm lub khob.
Nyob rau hauv lub qhov cub rau tib lub khob, tab sis tam sim no ncuav rau hauv nws ib tug tov ntawm cov nyiaj. Muab nws tshaj hauv lub khob.

Preheat qhov cub rau 900 degrees. Cov phaj maj daim iav zaj duab xis yuav tsum tshwm sim.
Yog xav tau ib tug tsis muaj kob crystalline hmoov mix nyob rau hauv ib tug tooj liab khob thiab ZnS (10: 100) thiab sov lub sib tov nyob rau hauv ib qhov cub.
Siv ib tug ntsia thawv "Tsapon" (rau bundles) thiab sib tov nrog rau cov hmoov. Tam sim no nrog kua no sib tov nyob rau hauv ib lub phaj thiab cia txoj kev nco rau kis. Saib xyuas kom tau ib tug txawm txheej. Txuas lub ob daim hlau, me ntsis compressing, qhuav rau lawv, thiab nyob rau thaum xaus ntawm tus txheej txheem lub resulting check sealing ntaus ntawv. Hmo ntuj pom kev tsom iav yog npaj txhij.
Tsis txhob hnov qab sau rau hauv Circuit Court high voltage generator!
Tam sim no peb muaj rau koj mus cuag tag nrho. Lub lens rau lub twj paj nruag, coj los ntawm cov koob yees duab thiab eyepiece - ib tug lenticular lens.
Tom qab xyuas tag nrho cov kev sib txuas, koj muaj peev xwm pib lub kev twb kev txuas. Qhov tseeb hais tias txhua yam yog ua hauj lwm kom zoo, koj yuav pom tus yam ntxwv squeak transformer.
Rau ib tug ntau tseeb duab yuav tsum tau hloov ob peb lub sij hawm thiab lub oscillator zaus thiab voltage theem.
Yog hais tias koj ua tau zoo, ces hmo ntuj pom kev tsom iav koj yuav tsis tau siv ib tug ntau ntawm cov nyiaj los ntawm yuav lawv nyob rau hauv lub khw.
