Chivabvu 20 izuva reWorld Metrology uye kusainwa kweinonzi Meter Kokorodzano kunorangarirwa. Inomiririrwa nenyika gumi nenomwe uye pakaitirwa musangano wayo wekutanga muna Chivabvu 20, 1875.
Musangano uyu unotiyeuchidza nezvekukosha kwakakosha kwekuve nemutengo wepasirese kana nhanho yechiyero pasirese pasirese. Iyi nzira inoshandiswa mune zvakawanda zvezuva nezuva zvinhu uye zvakakosha mabasa, sepasainzi, hutano, zvekutengeserana uye maindasitiri ekushandisa.
Chii chinonzi metrology?
Metrology ndiyo sainzi inodzidza kuyerwa, inofanirwa kuve yakarurama uye inoshanda muzvinhu zvakawanda uye muchidimbu ichizivikanwa nevanhu vese. Iyi poindi yakakosha zvakakosha kuitira kuti isu tese tigone kugovana nekuronga chese chinhu chatinoshandisa nacho nenzira imwecheteyo.
Somuenzaniso, metrology inoshandiswa muhutano hwevanhu. Vanhu vese vanoda hurongwa hwehutano panoshandiswa kuyerwa uye inyaya inoita basa rakakosha kwazvo. Neichi chokwadi, akawanda ma parameter anofanirwa kuyerwa kukwanisa kuita diagnoses.
Iko kugadzira uye kushambadzira kwezvigadzirwa uye zvese zvinowana kubva kwazviri unoda yakakwana yekuyera system, nenzira iyi vezvokutengeserana vachashandisa zvakafanana matafura pakureba uye uremu kuitira kuti pasave nekukakavadzana.
Satellite yekushambadzira masisitimu zvakare anovimba nechiyero. Ivo vanoshandisa imwecheteyo yepasi rose nguva kuenderana kunyatso tarisa nguva dzakanyatsoita senzvimbo. Muenzaniso unenge uri mukushandiswa kwekupima mu iko kubatana kwemakomputa akaomarara, uko munhu wese aizoishandisa, saka ndege inogona kufamba, kusimuka uye kumhara pasina kana kuoneka.
Zviyero zvemazuva ano zvekuyera zvakazvarwa sei?
Kunyangwe tekinoroji uye kwakawanda kufambira mberi kwedu kwanga kusipo mazana emakore apfuura, metrology yakagara iri nzira yekuyera. Yakagara iripo uye yakagadzira pamusoro pemakore uye zvichienderana nekushanduka kwenzanga mune imwe nguva.
Kwemakore apfuura iyi mhando yekuyera yakashandiswa yekutsvaga kwesainzi uye hunyanzvi. Kugadzira kwake kunogadzirirwa kusimudzira hupenyu hwevanhu, kugadzirwa kwemaindasitiri uye kutengeserana kwepasirese uye kunyangwe kuchengetedza nharaunda.
Iyo yekuyera system yakaberekwa muna 1789 panguva yeFrance Revolution, apo French National Assembly yakaronga kuChikemy of Sciences nzira itsva yemazuva ano yekuyera. Iwe waifanira kugadzira chitsva chakatsiga uye chakamira chiyero system kune wese munhu, uko tsoka nemaoko zvakange zvisisina kukosha. Isati yayerwa nehurongwa uhwu, asi kureba kwemaoko kana tsoka zvinosiyana zvichienderana nemunhu.
Nenzira iyi iyo centimeter yakatsanangurwa uye kubva ipapo zvakanzi zviwedzerwe litita sevhoriyamu. Mvura inopinda cube nerutivi rwegumi masendimita uye kilogiramu sehuremu hwerita remvura rakagadzirwa seyero. Madimikira akagadzirwawo, zvichiratidza kuwanda kwemayuniti aya kuti asiyane kubva pagumi kusvika pagumi.
Nezvirevo izvi iyo mita yakasikwa seyuniti yekuyera kureba, kugadzira iyo chaiyo kopi iyo yakachengetedzwa munzvimbo yekuchengetedza. Izvozvowo zvinoitika nekirogiramu, iyo sekutsanangura kwatingaita huremu hwemvura inokwana mumugomo, kureva, gumi cubic masentimita. Kurema kwakagadzirwa kwaizoshanda seyero yekirogiramu iyo yaizoponeswa semamita.
Mimwe yemhando yemayuniti ezviyero ayo anoshandiswa nhasi ndeaya: yehupfu: makirogiramu, magiramu; isu tinoshandisa iyo kureba: kiromita, mita; chinzvimbo: Kiloliter, litita; kupfuuridza nguva: maawa, maminitsi, masekondi, karenda; kuyerwa: scale; tembiricha: thermometer; kumanikidza: barometer, manometer.
Izvo zvakakosha kuti munhu wese azive iyi mhando yekuyeras saka hapana mutsauko. Masangano ese emunyika emetrology anoramba achienderera mberi kuti akure Izvo zvinoitirwa kutendwa nechivimbo uye kusimbiswa kune wese munhu.
