Nws yog siv kom pom qhov yooj yim ntawm cov qauv crystalline cov khib nyiab npaj lawv tus kheej hauv. Qhov chaw lattice yog ib qho ntawm cov ntsiab lus uas qhia tias cov khoom (atoms, ions lossis molecules) tau teeb tsa li cas ntawm qhov chaw sib txawv hauv peb qhov chaw. Chav tsev yog qhov yooj yim tshaj plaws kom pom hauv ob qhov loj me.
Puas yog qhov chaw nyob?
Qhov peb-dimensional network ntawm kev xav txog kab txuas atoms yog hu ua qhov chaw lattice. Ib tug siv lead ua yog ib qho kev npaj nyob rau hauv peb qhov ntev ntawm atoms los yog molecules nyob rau hauv cov qauv rov ua dua. Qhov tsawg tshaj plaws chav tsev uas muaj tag nrho symmetry ntawm cov siv lead ua yog hu ua chav tsev cell, cov npoo ntawm uas tsim peb axes: a, b, thiab c.
qhov chaw lattice yog dab tsi thiab nws qhov tseem ceeb?
Hauv cov khoom siv crystalline, cov atoms lossis molecules tau teem caij tsis tu ncua thiab ntu ntu hauv peb qhov ntev. Ib qhov chaw lattice sawv cev rau cov qauv geometrical ntawm cov siv lead ua uas nyob ib puag ncig ntawm txhua qhov lattice taw tes yog tib yam. …
Dab tsi yog qhov sib txawv ntawm cov lattice thiab qhov chaw lattice?
A 3D translationally periodic arrangement of atoms in a space is called a crystal. Ib qho 3D translationally periodic kev npaj ntawm cov ntsiab lus nyob rau hauv ib qho chaw yog hu ua ib tug siv lead ua. kev npaj ntawm cov ntsiab lus hauv qhov chaw yog hu ua lattice. Qhov kev sib raug zoo ntawm ob yog dab tsi?
Tus yam ntxwv tseem ceeb ntawm qhov chaw lattice yog dab tsi?
Txhua taw tes hauv qhov chaw lattice sawv cev rau ib qho atom lossis ib pab pawgatoms. Txhua lub ntsiab lus hauv qhov chaw lattice muaj ib puag ncig zoo ib yam thoob plaws. Ib pawg peb seem ntawm cov ntsiab lus lattice uas thaum rov qab rau hauv qhov chaw tsim cov siv lead ua hu ua unit cell.

Puas pom qhov tseem ceeb yog vim li cas lossis vim li cas ho tsis?
Kev sib txuas lus pom kev pab cov neeg tuaj saib nkag siab cov ntaub ntawv. Nws ua rau kom nkag siab txog cov ntsiab lus. Hom duab ob sab uas pab kev sib txuas lus muaj xws li kos duab, kos duab kos duab, animation, kos npe, typography, graphic designs, thiab lwm yam.
Qhov chaw tsis muaj chaw txhais li cas?
Txhua zaus Annie pom zaj sawv saum ntuj nws khiav mus ntes nws - tab sis yeej tsis muaj dab tsi. Muaj ib hnub nws caum tus zaj sib sib zog nqus mus rau hauv ib lub vaj tsis meej. Placelessness txhais li cas hauv tib neeg thaj chaw? Qhov xwm txheej ntawm ib puag ncig tsis muaj qhov chaw tseem ceeb thiab tus cwj pwm cuam tshuam ntawm qhov tsis muaj kev txuas rau qhov chaw tshwm sim los ntawm homogenizing cuam tshuam ntawm kev niaj hnub, piv txwv li.
Vim li cas qhov kub hnyiab ntawm qhov chaw muaj kev phom sij?
Circumferential tag nrho-thickness kub hnyiab nrog qhov ua rau poob ntawm daim tawv nqaij elasticity tuaj yeem tsim cov nyhuv tourniquet ntawm nqua thiab pob tw, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm qhov chaw perfusion, kev ua pa ntawm txoj hlab pas, thiab ua pa tsis zoo.
Puas yog qhov chaw ua si dutton yog qhov chaw zoo?
Kuv kev tshuaj xyuas tsis yog kev qhuas raws li kuv qhov kev paub nrog Dutton Park tau ua rau muaj kev tsis txaus siab thiab kev thab plaub hauv zej zog. … Thiab ntawm kev pheej hmoo ntawm kev txo qis ntawm kuv tus kheej cov khoom muaj nqis Kuv tsis tuaj yeem ua lub siab zoo pom zoo rau lub nroog no tshwj tsis yog tias koj tsis yog cov ilk los pab txhawb rau zej zog raws kev thab plaub.
Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?
Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
