Lub hom phiaj tseem ceeb ntawm vulcanization ntawm roj hmab yog txhawm rau txhim kho elasticity ntawm roj hmab ntawm qhov kub thiab qhov kub tsis tshua muaj.
Lub hom phiaj tseem ceeb ntawm roj hmab yog dab tsi?
Roj Hmab feem ntau yog siv los ua ua cov roj hmab bands thiab xaum erasers. Roj hmab ua los ntawm fiber ntau, qee zaum hu ua 'elastic', muaj txiaj ntsig zoo rau kev lag luam textile vim nws cov elongation zoo heev thiab cov khoom zoo.
Qhov zoo ntawm vulcanization yog dab tsi?
Qhov zoo ntawm Vulcanization:

Ntxiv rau kev hloov pauv nws qhov loj me thaum khaws nws cov duab, vulcanization tseem tiv thaiv roj hmab los ntawm kev deformation yav tom ntej. Raws li nws yog shrunk, roj hmab hardens thiab yuav tsis yooj yim rau deformation.
vulcanization siv qhov twg?
Vulcanized roj hmab yog siv los ua ntau yam khoom, suav nrog cov khau khau, hoses, hockey pucks, bowling balls, khoom ua si, log tsheb, bouncing balls, thiab ntau ntxiv. Feem ntau ntawm cov khoom siv roj hmabtsim yog vulcanized.

Lub hom phiaj ntawm kev tso roj thaum siv lub tshuab tsom iav yog dab tsi?
Immersion Roj pab txhawb rau ob tus yam ntxwv ntawm daim duab pom los ntawm lub tshuab tsom: daws teeb meem zoo dua thiab ci ntsa iab. Cov yam ntxwv no tseem ceeb tshaj plaws nyob rau hauv siab magnification; yog li nws tsuas yog lub zog siab dua, ua kom pom tseeb luv luv, cov hom phiaj uas feem ntau yog tsim los rau cov roj immersion.

Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Lub hom phiaj tseem ceeb thiab cov cai ntawm tcsec yog dab tsi?
TCSEC yog siv los ntsuas, faib, thiab xaiv cov tshuab computer uas raug txiav txim siab rau kev ua, khaws cia, thiab khaws cov ntaub ntawv rhiab lossis cais tawm. TCSEC, feem ntau hu ua Orange Book, yog qhov tseem ceeb ntawm DoD Rainbow Series cov ntawv tshaj tawm.
Dab tsi yog qhov tseem ceeb thiab vim li cas nws tseem ceeb los txheeb xyuas koj qhov tseem ceeb?

Qhov tseem ceeb tshaj plaws, qhov tseem ceeb tshaj plaws yuav ua rau koj ntseeg siab hais tias "tsis yog." Lawv pab koj txheeb xyuas qhov xav tau tiag tiag hauv koj lub neej, piv rau lwm tus xav tias tseem ceeb.
Puas yog lub hom phiaj lossis lub hom phiaj?
Suab nrov yog cov khoom ntiag tugntawm lub suab uas hnov hloov pauv thaum lub amplitude hloov pauv thaum lub zaus nyob tas li. Pitch yog lub ntsiab lus ntawm lub suab uas tau hnov los hloov thaum lub zaus hloov pauv thaum lub amplitude nyob tas li.
