Yuav kom pab cov tub ntxhais craftsmen yuav ua li cas yuav ua rau daim ntawv los ntawm lub tetrahedron

Yog hais tias mam li nco dheev koj tau ua txoj haujlwm rau ib tug geometry zaj lus qhia, los yog nws tus kheej ib tug muaj siab mus ua tshiab lub cim xeeb thaj chaw ntawm peb-dimensional nuj nqis, ces koj yuav tsum twv yuav raug hu nyeem yuav ua li cas yuav ua rau daim ntawv los ntawm lub tetrahedron, thiab nco ntsoov siv cov tswv yim rau hauv xyaum. Tom qab tag nrho, qhov no daim duab vim nws simplicity yog ib tug ntawm cov yooj yim qauv ntawm peb-dimensional modeling.

Lo lus "tetrahedron" yuav txhais los ntawm Greek raws li "tetrahedron". Tseeb, tus kwv nyob rau hauv lo lus nug muaj plaub voos ntsej muag thiab plaub vertices thiab rau sawv. Muaj ntau ntau subspecies ntawm no daim duab, tab sis peb yuav tsis tham txog txhua tau xaiv. Nyob rau hauv no tsab xov xwm koj yuav kawm txog txoj kev yuav ua li cas yuav ua rau daim ntawv tetrahedron. Qhov no yuav ua tau ib tug tsis tu ncua tetrahedron, tag nrho cov ntawm uas nws ntsej muag yog equilateral cov vajvoos peb sab.

Rau kev ua hauj lwm tsis tas yuav mus rau hauv lub complex zauv tsis tau suav tej volume ntawm ib tug tetrahedron, los yog ib thaj chaw los yog qhov siab. Qhov tshaj plaws xwb uas yog yuav tsum tau, - ib daim ntawv ntawm daim ntawv, ib tug cwj mem, cov txiab thiab kua nplaum, thiab cov SRES thiab yuav ua li cas xwb daim ntawv.

Txij li thaum ntawv yuav ua rau ib tug tetrahedron, nrog rau tag nrho cov tsim nyog cov ntaub ntawv? Muaj ob peb txoj kev. Cov thawj thiab nrov tshaj plaws kev xaiv: txiav plaub cais cov vajvoos peb sab nrog thiaj li hu ua "tej nplaim", uas yog ces glued ua ke. Koj muaj peev xwm kos ib tug equilateral daim duab peb sab ntawm lawv tus kheej los yog siv ready-made templates. Qhov zoo ntawm cov qauv no muaj xws li lub sij hawm rau shape ib multi-kob, noj daim ntawv ntawm cov xim txawv thiab ntxoov. Qhov tsab xov xwm yuav muab ib tug brightness thiab ib tug ntau nthuav saib.

Ib tug thib ob txoj kev muaj nyob rau hauv tsevneeg tsis cais cov vajvoos peb sab, thiab twb kev cob cog rua rau txhua lwm yam (thiaj li hu ua PP tetrahedron). Nyob rau hauv cov ntaub ntawv no, dhau lawm, tej zaum yuav muaj ob peb xaiv, namely rau gluing tus nplaim tej zaum yuav qhib sawv, los yog tsuas yog ib co, cov neeg uas muaj tsawg kawg yog rau ib tug ruaj ntseg haum.

Thiab thaum kawg, peb txoj kev saib yuav ua li cas yuav ua rau daim ntawv los ntawm lub tetrahedron, peb yuav pom tau tias yog tsis muaj yuav tsum tau txawm rau tej adhesives, vim hais tias lwm embodiment ntawm lub rooj sib txoos ntawm cov geometric duab yog modular origami. Ntawm no yog ib tug hollow pyramid yuav ua tau los ntawm kev thov rau cov qauv no, nrog ib tug Tshuag txaus daim ntawv, rau siab ntso thiab ua siab ntev. Nyob rau hauv Feem ntau, nws tsis yog heev, tab sis, theej laborious ua hauj lwm, thiab nyob rau hauv no tsab xov xwm peb yuav tsis muab ncauj lus kom ntxaws cov lus qhia. Yog hais tias koj xav nyob rau hauv cov ntaub ntawv no, koj yuav nrhiav tau nws nyob rau hauv lub qhov chaw mob siab rau qhov no Japanese kos duab. Thiab, Yog hais tias koj ua muab teeb meem mus nrhiav cov lus qhia nyob rau hauv no crafts, tsis ntev koj yuav tau yooj yim tau txawm xws li ib tug complex qauv.

Txhua yam ntawm tus saum toj no kev xaiv nws muaj nws zoo dua lwm tus, thiab lawv yog cov tag nrho tsim nyog thiab zoo. Thiab xaiv ib txoj kev uas yog txoj cai rau koj yuav tsum tau raws li nyob rau hauv cov nyob rau ntawm lub sij hawm thiab siab ntev, raws li zoo raws li lub hom phiaj ntawm ib tug yav tom ntej qauv ntawm lub tetrahedron.
