IMundima yekutsvagisa kwesainzi, kudzokororwa kwedata rekuyedza chinhu chakakosha pakuyera kuvimbika kwezvakawanikwa nesainzi. Chero kukanganiswa kwezvakatipoteredza kana kukanganisa kwekuyera kunogona kukonzera kutsauka kwemhedzisiro, nokudaro zvichideredza kuvimbika kwemhedziso yekutsvagisa. Nehunhu hwayo hwepanyama nemakemikari, granite inovimbisa kugadzikana kwekuyedza mumativi ese kubva pakuumbwa kwayo kusvika pakugadzirwa kwechivakwa, zvichiita kuti ive chinhu chakakodzera chemidziyo yekutsvagisa kwesainzi.
1. Isotropy: Kubvisa zvikanganiso zviri muzvinhu zvacho pachazvo
Granite inoumbwa nemakristaro emaminerari akadai se quartz, feldspar uye mica akapararira zvakaenzana, zvichiratidza hunhu hwechisikigo hwe isotropic. Hunhu uhwu hunoratidza kuti hunhu hwayo hwepanyama (sekuomarara uye elastic modulus) hunowirirana munzira dzese uye hahuzokonzere kutsauka kwekuyera nekuda kwekusiyana kwechimiro chemukati. Semuenzaniso, mukuyedza kwe precision mechanics, kana sampuro dzakaiswa papuratifomu yegranite yekuyedza kurodha, kushanduka kwepuratifomu yacho kunoramba kwakasimba pasinei nekwakananga simba rinoshandiswa, nokudaro zvichidzivirira zvikanganiso zvekuyera zvinokonzerwa ne anisotropy yekwakanangana nezvinhu. Kusiyana neizvi, zvinhu zvesimbi zvinoratidza anisotropy yakakosha nekuda kwekusiyana kwekutarisa kwekristaro panguva yekugadzirisa, izvo zvinokanganisa kusagadzikana kwedata rekuyedza. Naizvozvo, hunhu uhwu hwegranite hunovimbisa kufanana kwemamiriro ekuyedza uye hunoisa hwaro hwakasimba hwekuwana kudzokorora kwedata.
2. Kugadzikana kwekupisa: Ramba kukanganiswa kunokonzerwa nekuchinja-chinja kwekushisa
Kuedza kwesainzi kunowanzo nyanya kukanganiswa nekupisa kwezvakatipoteredza. Kunyangwe kuchinja kudiki kwekupisa kunogona kukonzera kuwedzera kwekupisa uye kudzikira kwezvinhu, zvichikanganisa kurongeka kwekuyera. Granite ine chiyero chakaderera kwazvo chekuwedzera kwekupisa (4-8 × 10⁻⁶/℃), inova hafu chete yesimbi yakakandwa uye chikamu chimwe muzvitatu chealuminium alloy. Munzvimbo ine kuchinja kwekupisa kwe ±5℃, shanduko yehukuru hwepuratifomu yegranite yakareba mita imwe isingasviki 0.04μm, izvo zvinogona kupotsa zvaregeredzwa. Semuenzaniso, mukuyedza kwekupindira kwemaziso, kushandiswa kwemapuratifomu egranite kunogona kusiyanisa zvinobudirira kusagadzikana kwekupisa kunokonzerwa nekutanga nekumira kwema air conditioners, nokudaro kuve nechokwadi chekugadzikana kwedata panguva yekuyerwa kwewavelength yelaser uye kudzivirira kupindirana kwefringe offsets nekuda kwekushanduka kwekupisa, nokudaro zvichivimbisa kuenderana kwakanaka uye kuenzanisa kwedata panguva dzakasiyana.
III. Kugona kukuru kwekudzora kudedera
Munzvimbo yerabhoritari, kuzununguka kwakasiyana-siyana (kwakadai sekushanda kwemidziyo uye kufamba kwevashandi) zvinhu zvakakosha zvinokanganisa mhedzisiro yebvunzo. Nekuda kwehunhu hwayo hwekudzikisa mvura, granite yave rudzi rwe "chipingamupinyi chechisikigo". Maumbirwo ayo emukati mekristaro anogona kushandura simba rekuzununguka kuita simba rekupisa, uye chiyero chayo chekudzikisa mvura chakakwira kusvika pa0.05-0.1, izvo zviri nani pane zvemidziyo yesimbi (inenge 0.01 chete). Semuenzaniso, mukuyedza kwe scanning tunneling microscopy (STM), nekushandisa granite base, kupfuura 90% yekuzununguka kwekunze kunogona kudzikiswa mukati memasekonzi 0.3 chete, zvichiita kuti daro riri pakati peprobe nepamusoro pemuenzaniso rigare rakagadzikana uye nokudaro zvichiita kuti mufananidzo weatomu ugare wakasimba. Pamusoro pezvo, kusanganisa granite platform nemasisitimu ekudzikamisa vibration akadai sema air springs kana magnetic levitation kunogona kuderedza zvakanyanya kukanganiswa kwe oscillation kusvika padanho re nanometer, zvichivandudza zvikuru kururama kwekuyedza.
Iv. Kugadzikana kweMakemikoro uye Kuvimbika Kwenguva Refu
Kutsvagurudza kwesainzi kunowanzoda kuongororwa kwenguva refu uye kudzokorora, saka chinodiwa chekugara kwenguva refu kwechinhu chakakosha zvikuru. Sechinhu chine hunhu hwemakemikari hwakagadzikana, granite ine pH yakawandisa (1-14), haisangani ne common acid ne alkali reagents, uye haiburitse ma ions esimbi. Nokudaro, yakakodzera munzvimbo dzakaoma dzakadai sema laboratories emakemikari nemakamuri akachena. Panguva imwecheteyo, kuoma kwayo kwakanyanya (kuomarara kweMohs kwe6-7) uye kuramba kwayo kupfeka zvakanaka kunoita kuti isanyanya kusakara kana kushanduka panguva yekushandiswa kwenguva refu. Data rinoratidza kuti kusiyana kwepuratifomu yegranite yave ichishandiswa kwemakore gumi mune imwe nzvimbo yekutsvagurudza fizikisi kuchiri kudzorwa mukati me ±0.1μm/m, zvichiisa hwaro hwakasimba hwekugara uchipa referensi yakavimbika.
Mukupedzisa, kubva pamaonero ekugadzirwa kwezvinhu zvishoma nezvishoma kusvika pakushanda kwehukuru, granite inobvisa zvinhu zvakasiyana-siyana zvinogona kukanganisa zvinhu zvine zvakanakira zvakawanda zvakaita se isotropy, kugadzikana kwakanyanya kwekupisa, kugona kudzvinyirira vibration, uye kugara kwenguva refu kwemakemikari. Mubasa rekutsvaga kwesainzi rinotsvaga kusimba uye kudzokorora, granite, ine zvayakanakira zvisingatsivike, yave simba rakakosha mukuona kuti data rechokwadi uye rakavimbika.
