Domes kuj tseem tiv taus cua daj cua dub, av qeeg, thiab hluav taws kub zoo dua li cov qauv duab plaub. Lawv twb tau siv rau cov tub rog radar systems, pawg ntseeg, auditoriums thiab tseem rau txhua yam tshwj xeeb cov xwm txheej uas yuav tsum tau muaj chaw nyob ib ntus, pheej yig thiab muaj zog.
Raws li txoj cai, lub hom phiaj ntawm geodesic domes yog dab tsi?
Cov geodesic dome yog ib tug qauv muaj geodesics , series ntawm cov kab ncaj nraim ntawm qhov chaw nkhaus uas sib tshuam los ua daim duab peb sab. Ib qho txiaj ntsig zoo tshaj plaws ntawm qhov kev tsim qauv no yog qhov kev ntxhov siab ntawm cov txheej txheem tau muab faib sib npaug thoob plaws, ua rau cov tsev muaj zog heev txawm tias siv cov khoom siv tsawg heev.
Tom qab, lo lus nug yog, puas yog geodesic domes zoo? Ib txoj cai geodesic dome muaj zog heev. Hauv cov tebchaws zoo li Greenland uas muaj cua daj cua dub heev, geodesic domes muab cov txiaj ntsig tseem ceeb. Coincidentally, lawv yog heev zoo rau kev ncig ntawm huab cua thiab cua sov yog li lawv kuj zoo rau huab cua txias heev.
Tsis tas li ntawd, qhov zoo ntawm geodesic domes yog dab tsi?
Qhov Zoo
- Lawv tiv taus cov ntsiab lus ntuj. Lub dome zoo yog qhov ua tau zoo ntawm cov khoom xws li cua thiab daus.
- Lawv muaj zog heev. Geodesic domes txhawb nqa huab cua zoo dua thiab ua kom sov txawm tias thoob plaws hauv cov qauv.
- Lawv muaj zog heev.
Lub geodesic dome yog dab tsi?
Geodesic dome , spherical daim ntawv nyob rau hauv uas lub teeb yuag daim duab peb sab los yog polygonal facets muaj xws li skeletal struts los yog pav ca dav hlau, loj nyob rau hauv nruj, hloov lub hauv paus ntsiab lus thiab faib cov kev ntxhov siab nyob rau hauv tus qauv nws tus kheej. Nws tau tsim nyob rau hauv lub xyoo pua 20th los ntawm American engineer thiab architect R.

Dab tsi yog qhov tsis zoo ntawm geodesic domes?
Feem ntau cov tuam txhab tshwj xeeb hauv geodesic domes muab lub hom phiaj ua qhov rais thiab npog. Thawj qhov tsis zoo: tau txais kev tso cai npaj yog qhov nyuaj hauv ntau qhov chaw. Cov neeg xav tias geodesic domes yog 'weird' lossis 'tsis haum nrog cov vernacular' thiab feem ntau tawm tsam lawv cov kev tsim kho
Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
