Iav tau dhau los ua ib feem tseem ceeb ntawm lub neej niaj hnub no thiab kev tsim khoom lag luam. Ntawm nws ntau hom,iav tsis muaj duabsawv tawm vim nws cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov hauv paus tseem ceebcov yam ntxwv ntawm iavthiab yog vim li cas lawv thiaj ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov xws lintim cov thawv iavrau kev siv architectural thiab optical.
Iav Yog Dab Tsi?
Iav yog ib qho tshwj xeebkhoom tsis yog crystallineTsis zoo li cov khoom siv crystalline, nws cov qauv molecular tsis ua raws li tus qauv ntev tab sis qhia txog kev txiav txim luv luv zoo ib yam li cov kua.
Ib txwm muaj, iav yog tsim los ntawm kev txias cov kua dej uas yaj. Nyob rau hauv xyoo tas los no, nws kuj tuaj yeem tsim los ntawmcov txheej txheem tsis yaj, xws li kev tso dej ua kua, hydrolysis, lossis irradiation. Ntawm qib microscopic, iav tsis muaj lub lattice ib txwm muaj, tab sis ntawm qhov ntsuas macroscopic, nws ua rau pom cov khoom siv kho tshuab zoo ib yam li cov siv lead ua - piv txwv li, nws qhov chaw tawg feem ntau qhia txog tus qauv zoo li plhaub.
Plaub Yam Tseem Ceeb ntawm Iav
1. Isotropy
Iav yog ib qhocov khoom siv isotropic, txhais tau tias nws muaj cov khoom zoo ib yam hauv txhua qhov kev taw qhia.
-
Lub zog, elastic modulus, thermal expansion, thermal conductivity, refractive index, thiab electrical conductivity tseem zoo ib yam tsis hais qhov kev taw qhia.
-
Qhov sib piv, cov ntaub ntawv crystalline feem ntau qhia anisotropy nyob ntawm qhov kev taw qhia.
-
Txawm li cas los xij, thaum muaj kev ntxhov siab sab hauv, isotropy yuav raug cuam tshuam, ua rau muaj cov xwm txheej xws li birefringence.
Qhov Zoo:Qhov isotropy no ua rau iav txhim khu kev qha thiab ruaj khov hauv cov teb xws li optics, ntim khoom noj, thiab khaws cia tshuaj lom neeg.
2. Kev ruaj khov ntawm Metastasis
Iav muaj nyob rau hauv ib qholub xeev metastable.
-
Los ntawm qhov pom ntawm thermodynamic, nws qib zog siab dua li ntawm cov khoom siv crystalline.
-
Los ntawm qhov pom ntawm kinetic, vim nws cov viscosity siab heev ntawm chav tsev kub, nws tsis tuaj yeem hloov pauv mus ua ib lub siv lead ua.
-
Tsuas yog nyob rau hauv qee qhov xwm txheej, thaum lub zog ua kom muaj zog rau kev siv crystallization raug kov yeej, tuaj yeem iav crystallize.
Qhov Zoo:Kev ruaj khov ntawm cov khoom siv ua rau cov iav ruaj khov mus ntev, ua rau nws tseem khaws cia tau zoo hauv cov xwm txheej ib txwm. Qhov no yog ib qho laj thawj tseem ceeb uas cov thawv iav zoo tagnrho rau kev khaws cia cov khoom noj thiab dej haus.
3. Kev Hloov Pauv Tsis Tu Ncua ntawm Cov Khoom Thiab Cov Khoom
Cov khoom sib xyaw ua ke ntawm iav tuaj yeem hloov pauv tas li hauv qee qhov ntau, thiab nws cov khoom hloov pauv raws li.
-
Tsis zoo li cov khoom siv crystalline, uas xav tau cov piv atomic ruaj khov, iav muaj kev ywj pheej ntau dua hauv kev tsim cov qauv.
-
Los ntawm kev kho nws cov khoom sib xyaw, iav tuaj yeem ua tiav cov khoom sib txawv, xws li pob tshab siab, tiv taus kua qaub thiab alkali, lossis txhim kho kev tiv taus thermal poob siab.
Qhov Zoo:Qhov kev ywj pheej no ua rau iav haum rau ntau yam kev siv, los ntawmcov fwj cawv thiab cov thawv ntim khoom nojrau cov khoom siv kho qhov muag thiab hluav taws xob siab heev.
4. Kev Hloov Mus Los Ntawm Khoom Thiab Yaj
Iav raug kev txom nyemkev hloov pauv maj mamntawm cov khoom khov thiab cov khoom yaj.
-
Cov khoom siv crystalline khov kho ntawm qhov kub ruaj khov, qhia txog kev hloov pauv sai sai.
-
Txawm li cas los xij, iav tsis muaj qhov kub thiab txias. Hloov chaw, nws mos dua li qhov kub thiab txias, hu uantau yam kev ua kom mos.
-
Hauv qhov ntau no, nws hloov pauv ntawm kev hloov pauv yas mus rau kev hloov pauv elastic yam tsis tsim cov theem crystalline tshiab.
Qhov Zoo:Qhov kev hloov pauv maj mam no ua rau iav yooj yim dua rau kev ua thiab ua kom zoo nkauj rau ntau yam thawv, xws liCov fwj cawv txiv hmab, cov fwj dej haus, cov thawv condiment, cov thawv zib ntab, thiab cov khob iav uas ua raws li koj xav tau.
Xaus lus
Hauv kev xaus lus, iav yog txhais los ntawm plaub yam ntxwv tseem ceeb:
-
Isotropy- cov khoom sib npaug hauv txhua qhov chaw.
-
Kev ruaj khov— thermodynamically tsis ruaj khov tab sis kineticly ruaj khov.
-
Kev hloov pauv tas mus li ntawm cov khoom sib xyaw thiab cov khoom— yooj ywm thiab customizable.
-
Kev hloov pauv tas mus li ntawm cov khoom khov thiab cov kua dej— yooj yim rau kev ua thiab ua.
Txhua yam khoom uas ua tau raws li plaub yam tseem ceeb no, txawm tias muaj tshuaj lom neeg sib xyaw ua ke li cas los xij, suav tias yog iav. Kev nkag siab txog cov yam ntxwv tshwj xeeb nocov yam ntxwv ntawm iavtsis yog tsuas yog ua rau peb txoj kev paub txog kev tshawb fawb tob zuj zus xwb tab sis kuj qhia txog vim li cas iav thiaj li yog cov khoom siv tau ntau yam rau lub neej txhua hnub thiab kev lag luam niaj hnub no.
