Daim tiab hauv cov style ntawm "elegant bochho" zoo li ntse thiab zoo nkauj. Qhov tseeb, kev txiav thiab xaws yuav tsuas yog ob peb teev xwb.
Qauv Tiab thiab Muab xam los ntawm kev txiav qhov chaw
Peb hu ua daim tiab no vim tias koj xav tau tsuas suav thiab tsuas yog ib qho ntsuas Ntawm (duav girth). Tom qab ntawd, nws tuaj yeem raug kos rau ntawm cov ntaub thiab txiav. Tag nrho cov kev suav hauv peb tus yam ntxwv ntawm Ntawm = 75 cm.
Daim tiab muaj peb lub squares - ib qho loj thiab ob qho me me, uas tau txiav ntawm daim phev thiab yog tau los ntawm 4 daim duab peb sab dawb. Qhov ntev ntawm lub loj square sab yog sib npaug nrog qhov dav ntawm cov ntaub (hauv peb qhov piv txwv - 150 cm).
Lub vojvoog ntawm lub voj voog (qhov rau lub duav), nrog lub duav), nrog rau lub plawv ntawm kev sib tshuam ntawm cov kab pheeb ces kaum ntawm lub square loj, los suav qhov yooj yim.
Ncig Ntawm = 2Pr, Na n = 3.14, r yog lub voj voos vojvoog. Thiaj li r = Ntawm / 2p = 75/2 * 3.14 = 12 cm.
Daim duab tuaj yeem luam tawm thiab saib nws, nyeem ntxiv cov ntawv nyeem thiab ua kom cov laij, hloov lawv cov ntsuas ntawm cov qauv hloov ntawm peb li.
Skirt hnub los ntawm lub square yuav luv heev ntawm cov chaw ncaj thiab ntev dhau los (OA). Yog li no, cov ntu luv ntawm daim tiab peb qhuas cov duab peb sab me me rau kab pheeb ces kaum ntawm OA.
Tag nrho cov kev xam kom mus raws li cov square loj, peb saib txhua tsab ntawv ceeb toom tsab ntawv.
Kom siab ntawm cov duab peb sab. Txheeb xyuas qhov sib txawv ntawm hypotenus ntev ntawm OA ntawm lub loj peb sab ntawm AOS thiab Cate ntev (OS).
Yog li, peb tau suav txhua qhov ntau thiab tsawg:
- Sab ntawm ib qho loj square = nqaij qhov dav = 150 cm
- OV = 1/2 ntaub dav = 75 cm
- r = Vajvoog vojvoog rau lub duav = 12 cm
- sab ntawm ib lub square me me = 44 cm
- Ntau tshaj plaws du = R = 106 - 12 = 94 cm nrog ib qhov dav ntawm cov ntaub so ntswg 150 cm thiab los ntawm = 75 cm.
- Ntaub siv rau peb tus piv txwv 2.0 m nrog qhov dav ntawm cov ntaub 1.5 m.
Curra thiab tiab sib dhos ua tshuab
Peb txiav ib qho loj square nrog ib sab ntawm 150 cm thiab ob lub plaub fab me me nrog ib sab ntawm 44 cm. Me squares txiav cov kab pheeb ces kaum txiav cov kab pheeb ces kaum thiab tau txais plaub daim duab peb sab. Qhov chaw ntawm lub xwmfab loj txiav lub qhov rau lub duav nyob rau hauv daim ntawv ntawm lub voj voog nrog lub vojvoog ntawm 12 cm.
Daim duab ntawm lub sijhawm teem ntawm ib qho peb tog rau ib sab ntawm ib qho xwm txheej loj yog muaj nyob rau hauv daim duab hauv qab no - nws yog sewn rau kartettes, hypotenuse yog hauv qab ntawm daim tiab. Qhov seem peb daim duab peb sab yog cov phuam ib yam li ib sab ntawm lub square.
Tom qab rho tawm tag nrho cov duab peb ceg, peb xaws qhib qhov chaw los ntawm kev sib txuas ntawm lub sijhawm hauv D. Cov tiab kis tau tus saib ntawm sab xis.
Fab paj nruag (hauv daim duab hauv qab no lawv tau qhia hauv cov ntsiab lus dawb) tuaj yeem tsau rau ntawm sab tsis ncaj ncees thiab khi hlua, yog tias koj tuaj yeem xaws cov hlua khi, thiab rau lub voj thib ob, tus tiab yuav ntau yooj yim so. Qhov ntev ntawm cov pos hniav yog pom ntawm qhov chaw.
Tsis txhob hnov qab nyob rau sab laug lossis sab laug ntawm qhov kev ncaj ncees ntawm txoj xov los ua tus zipper zipper. Tom qab ntawd ua txoj siv tawv thiab daim tiab yog npaj txhij. Hauv qab ntawm daim tiab muaj cov lus qhia oblique ntawm xov, thiab qhov ntev ntawm txoj kev taw qhia hauv peb qhov piv txwv yog 248 cm, uas tsis txwv txoj kev txav mus los. Daim tiab zoo nkauj zoo nkauj heev, nws yog qhov zoo, thiab tseem ceeb tshaj plaws - nws yog kev txaj muag sai sai.
