IMu rwego rw'ubushakashatsi bwa siyansi, gusubiramo amakuru y'igerageza ni ingenzi mu gupima icyizere cy'ibyavumbuwe mu bya siyansi. Ikosa iryo ari ryo ryose ryo kubangamira ibidukikije cyangwa gupima rishobora gutera ihinduka ry'ibyavuye mu bushakashatsi, bityo bigatera intege nke ku bwizerwa bw'umwanzuro w'ubushakashatsi. Kubera imiterere yabwo idasanzwe y'umubiri n'imiti, granite ishyigikira ihinduka ry'igerageza mu ngeri zose kuva ku miterere yaryo kugeza ku miterere y'inyubako, bigatuma riba igikoresho cy'ibanze cyiza cyo gukoresha mu bikoresho by'ubushakashatsi bwa siyansi.
1. Isotropi: Gukuraho amasoko y'amakosa ari mu bikoresho ubwabyo
Granite igizwe na kristu z'amabuye y'agaciro nka quartz, feldspar na mica zikwirakwira ku buryo bungana, zigaragaza imiterere karemano ya isotropic. Iyi miterere igaragaza ko imiterere yayo (nk'ubukomere n'uburyo bwo gushinyagura) ihoraho mu mpande zose kandi ntabwo izatera gutandukana kw'ibipimo bitewe n'itandukaniro ry'imiterere y'imbere. Urugero, mu bushakashatsi bw'ubuhanga bwo gukora neza, iyo ingero zishyizwe ku rubuga rwa granite kugira ngo hakoreshwe ibizamini byo gupakira, impinduka z'urubuga ubwarwo ziguma zihamye hatitawe ku cyerekezo imbaraga zikoreshwa, bityo birinda amakosa yo gupima aterwa na anisotropy y'icyerekezo cy'ibikoresho. Mu buryo bunyuranye, ibikoresho by'icyuma bigaragaza anisotropy ikomeye bitewe n'itandukaniro mu cyerekezo cya kristu mu gihe cyo gutunganya, ibyo bigira ingaruka mbi ku buryo amakuru y'igerageza ahora ahindagurika. Kubwibyo, iyi miterere ya granite ihamya ko imiterere y'igerageza ihuye kandi igashyiraho urufatiro rukomeye rwo kugera ku buryo amakuru asubirwamo.
2. Gukomera ku bushyuhe: Irinde kubangamirana guterwa n'ihindagurika ry'ubushyuhe
Ubushakashatsi bwa siyansi bukunze kwibasirwa cyane n'ubushyuhe bw'ibidukikije. Ndetse n'impinduka nto z'ubushyuhe zishobora gutuma ubushyuhe bukwirakwira no guhindagurika kw'ibikoresho, bityo bigira ingaruka ku buryo buboneye bwo gupima. Granite ifite igipimo gito cyane cy'ubushyuhe (4-8 × 10⁻⁶/℃), ari kimwe cya kabiri cy'icyuma gishongeshejwe n'igice cya gatatu cy'icyuma cya aluminiyumu. Mu bidukikije bifite ihindagurika ry'ubushyuhe rya ± 5℃, impinduka y'ingano y'urukuta rwa granite rufite metero imwe ni munsi ya 0.04μm, ibyo bikaba bishobora kwirengagizwa. Urugero, mu igerageza ry'uburyo bwo kubangamira ikirere, ikoreshwa ry'urukuta rwa granite rishobora gutandukanya neza ubushyuhe buterwa no gutangira no guhagarara kwa conditioner, bityo bigatuma amakuru ahora ahindagurika mu gihe cyo gupima ubushyuhe bwa laser kandi hirindwa ko ibintu bihindagurika bitewe n'ubushyuhe, bityo bigatanga icyizere cy'uko amakuru ashobora kumera neza kandi akagereranywa mu bihe bitandukanye.
Iii. Ubushobozi budasanzwe bwo gukumira gutigita
Mu rwego rwa laboratwari, imitingito itandukanye (nk'imikorere y'ibikoresho n'ingendo z'abakozi) ni ibintu by'ingenzi bigira ingaruka ku bisubizo by'ibizamini. Kubera imiterere yayo yo kugabanya ubushyuhe, granite yabaye ubwoko bw' "imbogamizi karemano". Imiterere yayo y'imbere ya kristu ishobora guhindura vuba ingufu zo kugabanya ubushyuhe mo ingufu z'ubushyuhe, kandi igipimo cyayo cyo kugabanya ubushyuhe kiri hejuru ya 0.05-0.1, ibi bikaba byiza cyane kurusha iby'ibikoresho by'icyuma (hafi 0.01 gusa). Urugero, mu igerageza rya microscopy ya scanning tunneling (STM), hakoreshejwe ishingiro rya granite, hejuru ya 90% by'imitingito yo hanze ishobora kugabanuka mu masegonda 0.3 gusa, bigatuma intera iri hagati y'icyuma n'ubuso bw'icyitegererezo iguma ihamye bityo bigatuma ishusho iri ku rwego rwa atome ihora ihamye. Byongeye kandi, guhuza urubuga rwa granite na sisitemu zo kwitandukanya imitingito nk'imyuka y'umwuka cyangwa ingufu za rukuruzi bishobora kugabanya cyane ukwivanga kw'ingufu ku rwego rwa nanometer, bikongera cyane ubuziranenge bw'igerageza.
Iv. Gukomera ku binyabutabire no kwizera igihe kirekire
Ubushakashatsi bwa siyansi bukunze gusaba igenzura ry’igihe kirekire kandi risubirwamo, bityo ibisabwa kugira ngo ibikoresho birambe ni ingenzi cyane. Kubera ko ari ibikoresho bifite imiterere ihamye ya shimi, granite ifite ubushobozi bwo kwihanganira pH (1-14), ntigira ingaruka ku bintu bisanzwe bya aside na alkali, kandi ntirekura iyoni z’icyuma. Kubwibyo, ikwiriye ahantu hagoye nko muri laboratwari za shimi n’ibyumba bisukuye. Hagati aho, ubukana bwayo bwinshi (ubukana bwa Mohs bwa 6-7) hamwe no kudashira neza bituma idasaza cyangwa ngo ihinduke mu gihe kirekire ikoreshwa. Amakuru agaragaza ko ihindagurika ry’ubugari bw’urukuta rwa granite rumaze imyaka 10 rukoreshwa mu kigo runaka cy’ubushakashatsi bwa fiziki rigicungwa muri ± 0.1μm/m, bigashyiraho urufatiro rukomeye rwo gutanga icyerekezo cyizewe.
Mu gusoza, uhereye ku miterere mito kugeza ku mikorere ya macroscopic, granite ikuraho ibintu bitandukanye bishobora kubangamira ibintu hamwe n'inyungu nyinshi nka isotropi, ubushyuhe buhamye, ubushobozi bwo gukumira gutigita neza, no kuramba cyane mu buvuzi. Mu rwego rw'ubushakashatsi bwa siyansi bukurikirana ubukana no gusubiramo, granite, hamwe n'ibyiza byayo bidasimburwa, yabaye imbaraga ikomeye mu kwemeza amakuru nyayo kandi yizewe.
