2. Tawm ceev M
Npuag ntom ntuag yog cov xov tooj ntawm cov xov paj lossis ntu ntev ntawm cov ntaub, qhia raws li cag / 10cm lossis cag / nti.
3. Cov ceev ceev E
Npuag zawm hais txog kev ua tiav ntawm cov xov ntawm kev sib khi hauv cov ntaub. Nws muab faib ua warp nruj thiab weft nruj. Nws yog qhia los ntawm qhov feem pua ntawm qhov sib txawv ntawm lub cheeb ntawm cov xov paj rau ib chav ntev.
4.Cuav coefficient
Cov laj thawj npog yog qhov feem pua ntawm cov xov paj' s qhov chaw ua kom thaj tsam ntawm cov ntaub npuag, denoted R
ncig ntev nruj Ew-- ua kom nruj nruj
5. Ntev, dav thiab tuab ntawm cov ntaub
Ntev: Qhov ntev ntawm tus nees, hauv meters.
Dav: hais txog qhov siab tshaj plaws tom qab kawg ntawm cov ntaub, hu ua dav. Cov ntsuas yog centimeters.
Thickness: Qhov nrug deb, ntsuas hauv millimetres, nruab nrab ntawm sab xub ntiag thiab sab nraub qaum ntawm cov ntaub hauv qab tej lub siab.
Lub hauv paus tseem ceeb cuam tshuam rau cov ntaub tuab:
Cov xov xov linear ntom ntom;
Npuag qauv;
Kev kawm ntawv ntawm cov xov paj buckling hauv cov ntaub;
Kev nruj thaum lub sijhawm tsim khoom thiab ua.
6. Nyhav rau ib cheeb tsam
Qhov hnyav ntawm ib txoj phuam yog feem ntau qhia hauv grams tauj ib square meter ntawm daim ntaub thiab raug hu ua qhov hnyav hauv cov square meter. Cov paj rwb ntaub feem ntau qhia nyob rau hauv cov nqe lus ntawm desizing qhuav hnyav ib square meter, thaum ntaub plaub ntaub yog feem ntau qhia nyob rau hauv cov nqe lus ntawm uniform nyhav ib square meter. Kuj tseem muaj lwm yam kev hais tawm, xws li qhov dav tag nrho ntawm ib 'meter', hnyav qhov hnyav, thiab lwm yam.
- warp ceev PW - weft ceev NTT - warp tus lej NTW - weft tus lej tshwj xeeb
Cov lus qhia saum toj no tsis xav txog kev shrinkage ntawm weft thiab noo noo rov qab ntawm cov ntaub.
