Cov ntaub so ntswg tau dhau los ua ib qho tsim nyog niaj hnub muaj nyob hauv tib neeg lub neej, thiab cov ntawv zoo kuj cuam tshuam rau tib neeg txoj kev noj qab haus huv. Yog li, qhov zoo ntawm cov phuam da dej tau sim? Feem ntau hais lus, muaj 9 qhov ntsuas ntsuas rau daim ntaub ntawv ntsuas kev ua haujlwm zoo: Ntev, kev hloov pauv ntawm qhov chaw mos, qhov, pob zeb ua pob thiab lwm yam ntsuas. Qhov zoo ntawm cov ntawv so tes yog txiav txim los ntawm kev sim. Yog li koj yuav sim cov ntawv phuam da dej li cas? Hauv tsab xov xwm no, peb yuav qhia txoj kev kuaj cov ntawv ntawm cov ntawv so tes thiab 9 cov cim kuaj pom.
Ua ntej, kev kuaj pom ntawm cov ntawv so tes
1, tsos
Cov duab da dej, suav nrog cov tsos ntawm lub ntim sab nraud thiab ntawv so tes. Thaum xaiv cov ntawv so tes, koj yuav tsum xub kuaj xyuas lub ntim. Ntim lub foob yuav tsum zoo huv thiab ruaj khov, tsis muaj tawg; Ntim yuav tsum tau luam tawm nrog lub npe ntawm cov chaw tsim khoom, hnub sau npe (zoo dua cov khoom lag luam (zoo dua qub
Thib ob, yog tshawb xyuas cov tsos ntawm qhov huv ntawm daim ntawv, tsis pom muaj cov kab mob uas tsis tshua muaj, pob zeb tawv thiab tsis txaus ntseeg, cov plaub hau tsis zoo, Hmoov zoo tshwm sim, txawm hais tias muaj ntawv tshaj tawm cov number cask.
2, Quantitative
Qhov ntawd yog, feem lossis cov naj npawb ntawm cov nplooj ntawv txaus. Raws li tus qauv, cov ntsiab lus khaws cov ntsiab lus ntawm 50 grams rau 100 grams ntawm cov khoom muag, qhov kev sib txawv tsis zoo yuav tsum tsis pub tshaj 4.5 Grams; 200 grams rau 300 grams ntawm cov khoom muag, yuav tsum tsis pub tshaj 9 grams.
3, whiteness
Daim ntaub so ntswg tsis yog lub xov tooj uas zoo dua. Tshwj xeeb daim ntawv so tes yuav ntxiv ib qho tshuaj dawb ntawm fluorescent. Fluorescent tus neeg sawv cev yog lub hauv paus txiv neej ua rau poj niam dermatitis, siv kev siv ntev yuav ua rau mob cancer.
Yuav ua li cas txheeb xyuas seb daim ntaub dawb fluorescent ntau dhau lawm? Nyiam nrog lub qhov muag liab qab yuav tsum yog cov phuam ntoo dawb, los yog muab daim ntawv spradiation (xws li cov peev xwm hluav taws xob (yog tias xiav fluorescence, nws ua pov thawj tias muaj cov tshuaj fluorescent. Qhov ci dawb tshaj qis txawm tias nws tsis cuam tshuam rau kev siv cov ntawv so tes, tab sis siv cov ntaub ntawv raw tsis zoo, kuj tsis txhob xaiv cov khoom lag luam no.
4, Kev nqus dej
Koj tuaj yeem tso dej rau ntawm nws kom nws nqus tau sai, tus ceev nrawm dua, qhov zoo dua cov dej nqus.
5, tom qab tensile index
Yog qhov nyuaj ntawm daim ntawv. Seb nws yog qhov yooj yim tawg thaum siv.
Qhov no yog qhov taw qhia tseem ceeb ntawm cov ntaub ntawv cov ntaub ntawv cov khoom lag luam, cov ntaub ntawv zoo yuav tsum muab cov neeg muag muag thiab xis nyob. Lub ntsiab tseem ceeb cuam tshuam rau qhov muag muag ntawm daim ntawv so ntswg yog cov khoom siv fiber ntau, wrinkling txheej txheem. Feem ntau hais lus, paj rwb pulp yog qhov zoo dua li ntoo pulp, cov nplais ntoo zoo dua li cov ntawv ntawm cov ntaub ntawv siv kom hnov qab.
7, qhov
Qhov ntsuas ntsuas yog tus naj npawb ntawm cov phuam so, cov qhov yuav tsis yog tsuas yog cov kev tsis zoo, hauv kev siv, tab sis kuj yooj yim kom tawg, cuam tshuam cov nyhuv ntawm kev so.
8, plua plav
Cov ntsiab lus uas yog daim ntawv yog hmoov av lossis tsis. Yog hais tias cov khoom siv raw yog nkauj xwb ntoo purp, nkauj xwb cov xyoob ntshav, cov plua plav tsis muaj teeb meem. Tab sis yog tias koj siv daim ntawv rov ua dua li cov ntaub ntawv raw, thiab cov txheej txheem tsis tsim nyog, txoj hmoov av yog qhov nyuaj kom tau raws li tus qauv.
Hauv cov ntaub ntawv luv luv, cov ntaub ntawv zoo yog cov kaus ntxhw dawb, lossis cov xim xyoob ua. Cov khaub ncaws hnav thiab cov ntaub qhwv huv, tsis muaj qhov, plua plav, thiab lwm yam, thaum kov cov tes tsis zoo, uas muaj cov hmoov, xim thiab txawm plaub hau poob.
