Muab piv cov khoom siv rau cov khoom siv kho hauv paus.

 

Hauv kev tsim kho cov khoom siv kho qhov muag, cov khoom siv yog qhov tseem ceeb los xyuas kom meej tias muaj kev ruaj khov, ua kom zoo, thiab kav ntev. Ntawm ntau cov ntaub ntawv muaj, granite tau dhau los ua ib qho kev xaiv nrov, tab sis nws piv rau lwm cov ntaub ntawv li cas?

Granite yog paub rau nws qhov tshwj xeeb rigidity thiab ntom ntom, cov khoom tseem ceeb rau cov khoom siv kho tshiab. Cov khoom pab txo qis kev co thiab thermal expansion, kom ntseeg tau tias cov twj kho qhov muag tau ceev lawv cov kev sib cav thiab raug. Tsis tas li ntawd, cov khoom siv tawm ntawm cov kev hnav thiab lub kua muag, ua rau nws xaiv qhov chaw ntev rau lub chaw ua hauj lwm thiab kev tshawb xyuas cov tsev.

Txawm li cas los xij, Granite tsis yog cov khoom siv uas tuaj yeem siv rau cov khoom siv kho qhov muag. Aluminium, piv txwv li, yog ib qho kev xaiv lub teeb uas muaj lub zog zoo thiab yooj yim rau lub tshuab. Thaum lub sij hawm txhuas mounts ua haujlwm tau zoo nyob rau hauv qee cov ntawv thov, lawv yuav tsis muaj tib theem kev co damping li granite. Qhov no tuaj yeem yog qhov tsis zoo rau cov high-precision optical system, raws li txawm tias kev nthuav dav me ntsis tuaj yeem cuam tshuam kev ua haujlwm.

Lwm tus continender yog cov khoom siv sib xyaw, uas tuaj yeem ua rau engineered los muab cov khoom tshwj xeeb raws li cov kev xav tau ntawm cov khoom siv kho tshiab. Cov ntaub ntawv no tuaj yeem tsim los ua lub teeb ci thiab muaj zog, tab sis lawv yuav tsis ib txwm phim cov stickal stability thiab rigidity ntawm granite. Tsis tas li ntawd, lub sijhawm ntev kev ua tiav ntawm kev sib xyaw tuaj yeem sib txawv, ua rau lawv tsis muaj peev xwm txhim khu kev qha ib puag ncig.

Hauv cov ntsiab lus, thaum granite sawv rau nws cov khoom ruaj khov thiab lub durability, kev xaiv ntawm cov khoom siv kho tshiab ntawm cov khoom siv tshwj xeeb ntawm daim ntawv thov. Thaum txiav txim siab, yam ntxwv xws li qhov hnyav, nqi, thiab ib puag ncig cov mob yuav tsum tau txiav txim siab ib puag ncig. Los ntawm ua tib zoo saib cov cuab yeej no, cov khoom tsim nyog tshaj plaws tuaj yeem raug xaiv kom ntseeg tau qhov kev ua tau zoo tshaj plaws ntawm lub cev.
