Kodi kutembenuka mamita lalikulu anawalondola? Kodi osiyana mita liniya pa mita lalikulu?

Komabe, aliyense wa ife mwaphunzira kusukulu, zabwino kapena zoipa - ndi funso lina. Ndipo, ndithudi, akadali pa sukulu tonse ndife bwino mfundo zosiyanasiyana muyeso wa chilichonse. Lita, kilogalamu, chachiwiri, mita ndi zina zotero. Koma nthawi zina pamakhala ngati mayunitsi, amene pa dzanja limodzi, zikuoneka bwino, koma kumbali ina, ndi kovuta kufotokoza kuti idzitha kuyezeka.

Zikuphatikizapo Mwachitsanzo, amanena mita. Gwirizanani - anamva mawu amenewa pafupifupi aliyense, koma kufotokoza kusiyana pakati pa mita ndi mita lalikulu, simungathe onse. Kodi izi wagawo mwachinsinsi, ndipo "mmene tiyenera kuchitira izo?"

mita

Pamaso lodziwa kusiyana pakati pa mita ndi mita lalikulu, tiyeni tikumbukire tanthawuzo leni "mita" ndipo kodi maganizo amenewa.

Kumene maphunziro mungakumbukire kuti mita amatchedwa njira kutalika chimene chimafika dzuwa pansi zingalowe 1 / 299,792,458 masekondi.

Ku Ulaya, m'zaka XV-XVI kulibe muyezo uliwonse, ochiritsira zotalika miyeso anatengedwa othetsera awo mu dera lililonse. Izi zinadzetsa zambiri anachitazi, kotero kale m'zaka za m'ma XVII anayamba kuganizira kufunika yatsopano wamba muyezo onse. Komanso latsopano muyeso kutalika sayenera zochokera chilakolako cha munthu akulamulira, ndi masoka, chodabwitsa zachilengedwe, zomwe sikudalira chifuniro wina aliyense.

Imodzi mwa mfundo izi anali kuika "mita" kutalika pendulum, kuchita chimodzi "Phokoso" wachiwiri limodzi. Komabe, kudzera zofufuza chinapezeka kuti chachiwiri theka nthawi oscillations wa pendulum imasiyana malingana ndi malo miyezo. Umo ndi momwe zatsimikiziridwa kuti pamene tikuyandikira equator mphamvu yokoka yafupika. Ndinayenera kupeza njira zina.

Patapita panali lingaliro zomangira kutalika muyeso kwa meridian lapadziko, monga momwe Adachitidwira Mwachitsanzo, ndi imodzi. Choncho, mu 1791, mita anali limanenedwa ngati mmodzi wa makumi wa Paris meridian, kapena khumi miliyoni wa mtunda kuchokera equator ku North Pole, monga anayeza pa longitude wa Paris. Komabe, tanthauzo limeneli ali kutali ndi komaliza. Patapita kusintha tanthauzo la mita kangapo - mu 1799, 1899, 1927,1960, motero. The tanthauzo yachiwiriyi anapanga 1983 - ndi zogwirizana ndi zimene tikudziwa pa maphunziro kusukulu.

akuthamanga mita

Kumvetsa mmene kutembenuza mamita lalikulu kufunafuna choyamba tiyenera kupeza chomwe izo zonse ziri.

Oddly okwanira, koma "mita" sangalankhule, chifukwa palibe mita zina, kupatula kuwathamangitsa, kodi kulibe. Tanthauzo lolondola ndi: "Kufunafuna kutalika kwa mankhwala - 1 mita." Choncho, 1 mita - muyeso Dina china chilichonse, kaya makhalidwe ake ena - m'lifupi, kutalika, kachulukidwe, misa, ndi zina zotero. Mwachidule, mita - ichi ndi mita kumene ife anazolowera, ndi amene angathe kuchita masamu ndi kayesedwe yosavuta, ntchito Mwachitsanzo, miyeso tepi kapena osiyanasiyana yaitali.

chakuti mungathe "kupotokola pa mpukutu»

Musanayambe muganize momwe kutembenuza mamita mbali kuwathamangitsa, kulongosolerana kamodzinso kuti mita ambiri, 100 masentimita. Nthawi zambiri, mawu ntchito mu malonda, pamene kuli kofunikira kuyeza ndi kuchuluka kwa chuma ukonde, m'lifupi amene kale kuwonjezekeredwa mu mtengo wa katundu. Per mita liniya, mwachitsanzo, kugulitsa linoleum, waya, chingwe mphamvu, waya, zosiyanasiyana zimakhala. Pofuna kudziwa mamita angati liniya pa mita lalikulu, m'pofunika muzipeza kuwerengetsera yosavuta - basi kuchulukitsa m'litali ndi m'lifupi.

Mwachitsanzo, ngati nsalu m'lifupi ndi 2 mamita 20 masentimita, mmodzi mita izo lidzaonekera chidutswa cha kutalika 1 mita ndi m'lifupi - 2,20. Mbali odulidwa kuti ndi wofanana ndi 2,2 mamita ^2.

Tsopano ife kupereka chitsanzo ndi kuwerengetsera osiyanitsidwa. Kodi kutembenuka mamita mbali kuwathamangitsa, ngati inu mukudziwa dera chinachake ndipo m'lifupi? Mwachitsanzo, chidutswa cha nsalu ya muofesiyo m'dera ndi 15,6 mamita ^2, ndipo m'lifupi - 3 mamita Ngati timachita n'zosiyana masamu, inu mukudziwa kuti kutalika kwa odulidwa adzakhala wofanana :.

15,6 mamita ^2: 3 mamita = 5.2 m, kapena masentimita 5 mamita 20.

Ndi wokongola wosalira zambiri koma M'pofunikanso kukumbukira kuti kugwira ntchito zowerengetsa mamita angati liniya pa mita lalikulu, popanda kudziwa m'lifupi mankhwala, izo sangathe.

Kodi kuyeza chinachake chimene sangathe sanamvere?

Komabe nthawi zina akuthamangira mamita kwa mayiko mawerengedwe chimaonekera chinachake sangathe adagulung'undisa zakuthupi. Mwachitsanzo, zidutswa za mipando ndi khitchini khoma. Kodi zimenezi zingatheke bwanji?

Pankhaniyi lomasuliridwa mamita lalikulu la safuna chabe chifukwa ndi sitingathe kuchita. Pankhaniyi, Mlengi chabe akutanthauza ngati mtengo makonzedwe, amene kale m'gulu ndalama ntchito, mtengo wa katundu ndi zigawo zikuluzikulu, magetsi ndi zina zotero. Zilibe kanthu momwe maalumali ambiri adzakhala mu loka wanu watsopano, mtengo wotchedwa okha kutalika.

Mbuna miyezo ngati

Komabe, angathe kupita cholakwika ndi njira mawerengedwe. Nthawi zambiri makasitomala kukayesedwa ndi mtengo wochepa, anaitana mita, pali unpleasantly anadabwa pamene mipando Chipinda Cowonetsera woyang'anira adzakangamira kuwerengetsera chomaliza.

mfundo ndi yakuti mu nkhani iyi unali otchedwa kwambiri pafupifupi mtengo, masamu ndi kugwiritsa ntchito mfundo kusinthidwa mipando ndi zipangizo yotsika mtengo. ndalamazo anali phatikizapo mtengo wa galasi, countertops, anamanga-mu kuwala, ndipo ngakhale Chalk mwachizolowezi. Onse mungachite izi amasankhidwa payekha malinga ndi zofuna kasitomala ndi kwambiri pa kuchuluka komaliza.

Choncho, mita makampani mipando ntchito kokha kudziwa otsika (chiyambi) mitengo ya zinthu, ndi makasitomala yekha amene amapanga zotheka kuganizira mlingo ambiri a mitengo mfundo za kampaniyo.

Pomaliza

Tsopano inu mukudziwa mmene kumasulira kanema lalikulu zomangira phewa ndi kumbuyo. Kudziwa zimenezi kudzakuthandizani kukhala zothandiza inu, makamaka milandu amenewa m'pofunika kugula chinachake "pa kanema wa." Yesani pamaso kugula kuti kuwerengetsera zonse zofunikira, ndipo ngakhale kawiri-fufuzani iwo kangapo. Ndipotu, zidzakhala zokhumudwitsa kwambiri pamene inu mupeza kuti overpaid kwa zinthu kuposa chofunika, kapena oipitsitsa - anagula zosakwana ankafuna. Kumbukirani, monga mwa chilamulo "Pa chitetezo cha katundu ogula, tiyeni tipite" pa kanema ndi, "anabwerera kapena anasinthanitsa sangakhale.
