Kana wakamboverenga pepa remaspec sheet emutengesi ukaona mutsetse wakaita sekuti “wakarongwa, unoteverwa nezvinodiwa nenyika,” zviri nyore kuapfuura nepauri seboilerplate. Hazvifanirwe kudaro. Kutevedzana ndechimwe chezvinhu zvishoma zviri papepa remaspec sheet zvinogona kusimbiswa, uye zvakare chimwe chezvinhu zvinonyanya kutaurwa zvakanyanya.
Cheni yacho, yakatsanangurwa zviri nyore
Kutevedzana kwezvishandiso zvinoreva kuti kururama kwechishandiso chekuyera kunogona kubatanidzwa, kuburikidza neketani isina kuputsika yekuenzanisa, kudzokera kune mwero unozivikanwa wenyika kana wepasi rose. Mukuita izvi zvinoita sepiramidhi: sangano renyika remetrology — NIST muUS, PTB muGermany, NIM muChina, NPL muUK — rinochengetedza mwero wekutanga wekutarisa. Ma laboratori ekuongorora edunhu ane mvumo anoenzanisa michina yavo yekutarisa nemwero wekutanga pane imwe nguva yakatarwa. Zvishandiso zvekuongorora zvefekitori — zviratidzo zvekuyeresa, mainterferometer elaser, mazinga emagetsi — zvino zvinoongororwa nemwero wekutanga werabhoritari, negwaro rinoratidza kuenzanisa, kutsauka kwakayerwa, uye zuva.
Bvisa chero chinongedzo chiri mucheni iyoyo uye izwi rekuti "calibrated" rinorega kureva zvakawanda. Chishandiso chakagadziriswa kamwe chete, makore mashanu apfuura, pachishandiswa michina iyo pachayo isingazombotevedzerwi kubva kusangano renyika, hachina kusiyana nechinhu chisina kugadziriswa - chinongova nesticker inoita kuti chitaridzike zvakasiyana.
Nei izvi zvichikosha zvikuru pamapuratifomu egranite nematombo
Mapureti epamusoro egranite nemapuratifomu ekuyera zvakarurama muenzaniso wakanaka wekuti kutevedza kunoregeredzwa sei. Kusatsetseka pazvigadzirwa izvi kunowanzo tsanangurwa zvichienderana nechiyero chenyika — DIN 876 ne DIN 875 yeGermany, American GGG-P-463C, JIS B 7513 yeJapan, standards dzeChina dzeGB, BS 817 yeBritain, kana ma framework akafanana muFrance neRussia. Standard yega yega inotsanangura kutsaudzika kunotenderwa pakati pemaplates akasiyana uye magiredhi (kazhinji Giredhi 00, Giredhi 0, Giredhi 1, Giredhi 2). Plate yakanyorwa kuti "Giredhi 0" haina zvazvinoreva pasina gwaro rekuti yakayerwa sei, kuti chii chakayerwa, uye kana calibration yemudziyo iwoyo ichiyerwa.
Apa ndipo panonyanya kukosha musiyano uripo pakati pekuyera interferometer nekutarisa straightedge yemakanika. Laser interferometer inogona kugadzirisa kutsauka kwakapfava padanho re nanometer uye pachayo inogadziriswa zvichienderana nechiyero chewavelength che optical, icho chinogona kuteverwa zvakananga sekuyera. Kuenzanisa straightedge kwakaongororwa nemaoko kunokurumidza uye kwakachipa, asi kune bhendi rekusava nechokwadi rakakura, uye marabhoritari ane mukurumbira anowanzo taura pachena kuti ndeipi nzira yakashandiswa pachitupa chakapihwa.
Rondedzero pfupi yevatengi
Kune chero ani zvake anotauramichina chaiyo— mapuratifomu egranite, zvishandiso zveCMM, mibhedha yematurusi emuchina — mibvunzo mishoma yakakodzera kubvunzwa kune chero mutengesi usati watora chikumbiro "chakayerwa" pamutengo chaiwo:
- Ndeipi mwero wenyika kana yepasi rose yakaitwa chiyereso ichi, uye chitupa chinochitsanangura zvakajeka here?
- Ndeipi labhoritari yakaburitsa chitupa chekuongorora, uye labhoritari iyoyo pachayo inotenderwa nesangano renyika remetrology rinozivikanwa here?
- Ndeipi mudziyo wakashandiswa pakuyera, uye pane zuva rekuongorora uye rekodhi yekuteverwa kwemudziyo iwoyo here?
- Chitupa chechikamu chine nhamba dzeserial chiri kutumirwa here, kana kuti gwaro remhando yepamusoro remuchina wechigadzirwa?
Hapana chimwe chezvizvi chiri ruzivo rwechinyakare — vatengesi vane mukurumbira vanopa ruzivo urwu senyaya yechokwadi, kazhinji vasina kubvunzwa kaviri. Zviitiko apo zvinova zvakaoma kuwana mhinduro yakatwasuka kazhinji ndizvo zvinhu zvinofanirwa kungwarira.
