Ezweni elibaluleke kakhulu lobunjiniyela bezindiza, ukwenziwa kwe-semiconductor, kanye nokulawulwa kwekhwalithi yezimoto, umkhawulo wephutha uncipha uye ku-zero. Uma ulinganisa izingxenye ezingeni le-micron—noma ngisho nele-sub-micron—, isisekelo sokulinganisa kwakho siba yinto ebaluleke kakhulu ekamelweni. Leli qiniso lisiletha ezintweni eziye zahlala isikhathi eside, kodwa ezihlala zisezingeni eliphezulu lesayensi yezimboni: ipuleti elimnyama le-granite laseJinan.
Izivakashi esikhungweni sethu zivame ukubuza ukuthi kungani sihlala sizibophezele kangaka kule nsiza ethile ye-geological. Impendulo itholakala esakhiweni sama-molecule esiyingqayizivele se-Jinan black granite, esinikeza izinga lokuzinza izinto zokwenziwa nezinye izinhlobo zamatshe ezingenakukwazi ukuliphinda. Uma sikhuluma ngepuleti lokuhlola i-granite, asixoxi nje ngetshe elisindayo; sixoxa ngethuluzi eliklanywe kahle kakhulu elisebenza “njenge-absolute zero” yelabhorethri yakho yokuqinisekisa ikhwalithi.
Isayensi Yokuzinza
Isizathu sokuthi izikhungo eziningi zocwaningo ezihamba phambili emhlabeni zibeka phambiliIpuleti elingaphezulu le-granite elimnyama laseJinanNgaphezu kwezinye izindlela ezishibhile kuncike ekukhuleni kokushisa kanye nokunciphisa ukudlidliza. I-Jinan granite iminyene ngokumangalisayo futhi ine-coefficient ephansi kakhulu yokukhula kokushisa. Endaweni yelabhorethri lapho amazinga okushisa angashintsha khona kancane, le granite ihlala izinzile ngokwesilinganiso. Ngokungafani nensimbi ecijile, engagoba noma idinga ukugcotshwa njalo ukuze kuvinjelwe ukugqwala, ipuleti le-granite alina-magnetic ngokwemvelo futhi alimelani nokugqwala. Lokhu kuqinisekisa ukuthi ama-geji akho okuphakama kwe-elekthronikhi abucayi kanye nezinkomba zokudayela azithintwa ukuphazamiseka kwe-magnetic, okunikeza indawo "ehlanzekile" yokuqoqwa kwedatha.
Kodwa-ke, itshe ngokwalo liyingxenye nje yendaba. Ukuze kufezwe ukunemba kwangempela, uhlelo lokufaka kumele lube yinkimbinkimbi ngokulinganayo. Yilapho ubunjiniyela besisekelo esihlanganisiwe buqala khona ukusebenza. Ipuleti elingaphezulu linembile kuphela njengokulinganisa kwalo. Uma isakhiwo sokusekela esingaphansi sibuthakathaka noma sakhiwe kabi, ipuleti lingawa ngaphansi kwesisindo salo esikhulu, lethule umphumela "wokugoba" owonakalisa imininingwane yokusicaba. Ithimba lethu lobunjiniyela ligxile ekwakheni uhlaka lokusekela oluhlanganisiwe olusebenzisa amapayipi ensimbi aqinile, ahlanganisiwe ngokunemba ukuqinisekisa ukuqina okuphezulu. Lawa mafreyimu aklanywe ngamaphuzu athile okusekela—ngokuvamile alandela uhlelo lwephuzu le-Airy—ukunciphisa ukuphambuka nokuqinisekisa ukuthi itshe lihlala lisicaba ngokuphelele kuyo yonke impilo yalo yokusebenza.
Ngale Kokungaphezulu: Ukwenza Ngokwezifiso Nokuhlanganiswa
Ukukhiqiza kwesimanje kuvame ukudinga okungaphezu nje kwetafula eliyisicaba. Sibona isidingo esikhulu sezixazululo ezihlanganisiwe, njengei-granite ephakanyisiwe(noma i-granite riser). Lezi zingxenye zibalulekile lapho ukusethwa kokuhlolwa okujwayelekile kudinga ukuphakama okwengeziwe noma i-offset ethile ukuze kuhlangatshezwane nezingxenye eziyinkimbinkimbi ze-3D. I-granite rised ivumela ukunwetshwa kwe-envelope yokulinganisa ngaphandle kokulahlekelwa yizimfanelo zokuncibilikisa zezinto eziyisisekelo. Ngokusebenzisa i-granite emnyama efanayo ye-Jinan yezikhulisi njengoba senza epuletini eliyinhloko, siqinisekisa ukuthi yonke inhlangano ye-metrology isabela ngokufanayo emvelweni, igcina ubuqotho bokulinganisa.
Inqubo yokudala izinga lomhlabaipuleti lokuhlola le-granitekuwumsebenzi wokubekezela nokunemba. Kuqala ekujuleni kwemigodi yaseJinan, lapho kukhethwa khona amabhlogo angenaphutha kakhulu. Noma yikuphi ukufakwa noma ukuqhekeka etsheni kungaholela ekungazinzini kamuva. Uma ibhloko eluhlaza isinqunyiwe, umsebenzi wangempela uqala: ukugoqa ngesandla. Ngenkathi imishini ingenza ipuleti lisondele ezilinganisweni zalo zokugcina, ukuba yisicaba kweBanga 00 lokugcina noma "iBanga Lelabhorethri" kufezwa ochwepheshe abangochwepheshe abachitha amahora amaningi, ngezinye izikhathi izinsuku, begoqa ubuso ngesandla. Lokhu kuthinta komuntu kudala ukuthungwa kobuso okuvumela imishini ephethe umoya ukuthi ishelele kalula, isici esibaluleke kakhulu embonini ye-semiconductor.
Kungani Abaholi Bomhlaba Wonke Bekhetha I-ZHHIMG
Kwa-ZHHIMG, sikholelwa ukuthi ukuba ngumhlinzeki osezingeni eliphezulu akukhona nje ukuthengisa umkhiqizo; kumayelana nokunikeza ukuqiniseka kokuthi idatha yakho ilungile. Uma unjiniyela ebheka ipuleti elimnyama le-granite surface likaJinan esisekelweni sethu esihlanganisiwe, akabheki nje imishini; ubheka isiqinisekiso sekhwalithi. Ukuzibophezela kwethu ezindinganisweni eziphakeme kakhulu kusibeke phakathi kwabakhiqizi abaphezulu bomhlaba abaqashelwa ngokugqwesa ku-metrology.
Siyaqonda ukuthi kumakhasimende ethu eYurophu naseNyakatho Melika, ukuthembeka akunakuxoxiswana ngakho. Ukuthumela itshe elingamathani amaningi ngaphesheya kolwandle akudingi nje kuphela ubuchwepheshe bokuthutha kodwa futhi nomkhiqizo ofika usukulungele ukusebenza. Ipuleti ngalinye lokuhlola i-granite eliphuma esikhungweni sethu lihlolwa kanzima ngama-laser interferometers ukuqinisekisa ukuthi liyisicaba kulo lonke indawo. Asigcini nje ngokuhlangabezana nezindinganiso ze-ISO; sihlose ukuzichaza kabusha.
Ukuthuthuka kwe-metrology kuya ngokuya kuzenzakalelayo kanye nokuskena ngesivinini esikhulu, kodwa isidingo sesisekelo esizinzile nesiyisicaba asikashintshi. Kungakhathaliseki ukuthi usebenzisa i-manual height gauge noma ingalo yerobhothi yesimanje, i-Ipuleti elingaphezulu le-granite elimnyama laseJinanIhlala ingumlingani othule empumelelweni yakho. Imunca ukudlidliza kwephansi lefektri, imelana nokuguguleka kokusetshenziswa kwansuku zonke, futhi ihlinzeka ngesisekelo sangempela lapho kulinganiswa khona ukusungula izinto ezintsha.
Njengoba sibheke ikusasa lokukhiqiza ngokunemba, sikumema ukuthi ucabangele isisekelo sezinqubo zakho zokulawula ikhwalithi. Ingabe ukusethwa kwakho kwamanje kunikeza ukuzinza okudingwa yizingxenye zakho ezibekezelela kakhulu? Ngokutshala imali epuletini lokuhlola le-granite lezinga eliphezulu kanye nokusekelwa okuqinile okuhlanganisiwe, awuthengi nje ithuluzi—uqinisekisa ukunemba kwayo yonke ingxenye eshiya ifektri yakho iminyaka ezayo.
