How to exchange mativi metres mukutsvaka? Chii chakasiyana Linear mita pa mativi mita?

Chokwadi, mumwe nomumwe wedu akadzidza kuchikoro, chakanaka kana chakaipa - ndechimwe mubvunzo. Uye, chokwadi, achiri kuchikoro isu vanoziva akasiyana tsika nokuyerwa chinhu zvose. Fő, kilogram, wechipiri, mutinhimira uye zvichingodaro. Asi dzimwe nguva pane anokwana zviyero akadaro, izvo kurudyi mumwe, zvinoita sokuti yakajeka, asi Ukuwo, zviri zvakaoma kutsanangura kuti vari kuyerwa.

Izvi zvinosanganisira Somuenzaniso, rinoreva mita. Bvumiranai - akanzwa mutsara uyu anenge munhu wose, asi kutsanangura musiyano mita kubudikidza mativi meter, haagoni zvose. Chii ichi chisinganzwisisike Unit, uye "sei kurapa nayo?"

mita

Asati yokuzvifungidzira kubuda kusiyana mita kubudikidza mativi meter, ngatirangarirei zvinoreva chaiko "mita" uye kupi akaita pfungwa iyi.

Chokwadi kwakarongwa ungayeuka kuti mita anonzi nzira pakureba iyo kunosvika chezuva pasi Vacuum nokuda 1 / 299,792,458 seconds.

MuEurope, nyika XV-XVI emakore hariko chero mureza, kwakajairika urefu matanho akatorwa pakubata dzavo neimwe munharaunda. Izvi akasika yakawanda zvingasanakira, saka atova XVII remakore vakatanga kufungisisa kudiwa yokusuma mutsva zvakafanana mureza zvose. Uyezve, chiyero itsva urefu hakufaniri inobva chido kutonga munhu, uye mune zvakasikwa, dzinongoitika chakajairika, izvo hakubvi zvake kuda.

Imwe pfungwa idzi kwaiva kugadza "mita" pakati zvakavamba kuchinja urefu, vakaita rimwe "vibrations" mune imwe wechipiri. Zvisinei, kuburikidza kuferefeta yakanga Vakawana kuti yechipiri hafu-nguva oscillations pakati zvakavamba kuchinja dzinosiyana-siyana zvichienderana nzvimbo kuyerwa. Ndizvo zvazvichaita zvave vakaratidza kuti sezvatinosvika pedyo neequator simba regiravhiti ipfupi. Ndaifanira kuwana dzimwe nzira.

Papera chinguva paiva pfungwa kusungirira kureba kuyerwa kuti pano Meridian, sezvaiitwa Somuenzaniso, aine maira. Saka, muna 1791, ari mita akanga kurondedzerwa somumwe makumi mana pakati Paris Meridian, kana mumwe-millionth gumi kure neequator kusvika North Pole, sezvo akayera panguva Longitude muParis.

achimhanya mita

Kuti tinzwisise sei kutendeutsa mativi metres vachidzingirira, kutanga tinofanira kuziva chii zvose pamusoro.

Oddly zvakakwana, asi "mita" haigoni kutaura, nekuti hakuna mumwe meter, kunze achitevera, havapo. Yakarurama yeshoko iri: "Kutsvaka kureba chigadzirwa - 1 mita." Saka, 1 mita - chiyero naDina chero chigadzirwa, zvisinei ayo mamwe maitiro - upamhi, urefu, arambe achirema, vakawanda, uye zvichingodaro. Zvichitaurwa zviri nyore, kuti mita - ndiwo mita dzataitumirwa vakajaira, uye izvo zvinogona dzaona nokuda nyore kuyerwa, kushandisa Somuenzaniso, tepi matanho kana zvenguva refu.

Usati edza sei kutendeutsa mativi metres kuti Vatevere, kujekesa kamwe zvakare kuti ndicho meter, 100 masendimita. Kakawanda, izvi izwi rinoshandiswa kutengeserana, kana zvakakodzera kuti kuyera svinga padandemutande zvokunyama, noupamhi uko yaitova ari mutengo kwenhumbi. Per Linear meter, semuenzaniso, tengesa linoleum, waya, simba wire, waya, siyana munyama. Kuti vazive kuti vangani Linear metres pa mativi meter, zvinokosha kuti zvimwe Masvomhu nyore - chete vawande kureba pedyo upamhi.

Somuenzaniso, kana jira upamhi ndiyo 2 metres 20 masendimita, mumwe mita zvichaita seungano chigamba kureba 1 M uye upamhi - 2.20. A vendu nzvimbo kuti yakaenzana 2,2 mamita ^2.

Zvino isu kupa muenzaniso pamwe Ivan Kuchin Masvomhu. How to mativi metres kuna achitevera, kana uchiziva nzvimbo chinhu uye yakafara? Somuenzaniso, nhindi makapeti nzvimbo iri 15.6 mamita ^2, uye yakafara - 3 M Kana tichiita zvinopesana neizvi masvomhu, imi munoziva kuti Kureba chekawo achava akaenzana :.

15.6 mamita ^2: 3 M = 5.2 m, kana 5 m kusvika 20 cm.

Zviri tsvarakadenga nyore, asi zvinokosha kuyeuka kuti compute vangani Linear metres pa mativi meter, pasina kuziva upamhi chigadzirwa, hazvitomboiti.

How kuyera chinhu kuti hazvigoni kushoma?

Dzimwe nguva, zvisinei, inoyerera metres kuti zvivanakire kukarukureta kunoonekwa chinhu chisingagoni anokungurutsirwa zvinhu. Somuenzaniso, zvidimbu midziyo uye kicheni rusvingo. kuti unogona sei kuva?

Panyaya iyi yeshanduro mativi metres kwamuri havadi chete nokuti hazvibviri kuita. Panyaya iyi, kuti mugadziri kungoti anoreva rudzi zvimiso mutengo, izvo kare zvaisanganisira basa mari, mari nezvinhu uye zvinoriumba, magetsi uye zvichingodaro. Hazvina basa kuti echiShinto zhinji ichava yokuchinjira mbatya kuchikoro kwako itsva, mutengo anonzi chete kureba.

Misungo kuyerwa dzakadaro

Zvisinei, zvakawanda zvinogona kuenda chakaipa ichi kukarukureta nzira. Kazhinji vatengi akaedzwa low mutengo, akadana meter, pane unpleasantly kushamiswa kana fanicha showroom maneja uchanamatira okupedzisira Masvomhu.

Chokwadi ndechokuti iyi pakutanga kunzi zvakare anofungidzirwa kukosha, dzaona pokushandisa mureza dikidiki midziyo uye yakachipa pashiri zvinhu. mari iyi akanga asina zvaisanganisira mari girazi, countertops, yakavakwa-muchiedza, uye kunyange dzose nenhumbi. All zvaungasarudza izvi vanosarudzwa nomumwe maererano mutengi zvinodiwa uye yekudyidzana zvinowedzera wokupedzisira mari.

Saka, zviri mita iri midziyo indasitiri chete inoshandiswa kuona yakadereresa (kutanga) mari inoshandiswa, uye mutengi chete zvinoita kuti pfungwa mukuru nenhanho Pricing wokuti zvakasimba.

mhedziso

Zvino imi munoziva tsoziva kushandura mativi footage ari apamafudzi uye musana. Zivo yakadaro achava richishanda kwauri, kunyanya avo zviitiko apo zvakakodzera kutenga chinhu "pamusoro footage." Edza pamberi kuritenga kuti zvakafanira zvose Masvomhu ari, uye kunyange kaviri-tarisa kuti kanoverengeka. Handiti, zvichava kunoodza mwoyo kwazvo kana uchiona kuti iwe overpaid mashoko kupfuura zvinodiwa, kana kuipa - akatenga zvishoma pane zvaaida. Rangarira, maererano nomutemo "On kudzivirira vatengi 'zvinhu, regai vaende" pamusoro footage, "vakadzokera kana vakatsinhanisa havagoni kuva.
