Machira asina kurukwa anewo nzira dzawo dzekuyera ukobvu nekurema. Kazhinji, ukobvu hunoverengerwa mumamirimita, nepo huremu huchiverengerwa makirogiramu kana matani. Ngatitarisei kune dzakadzama kuyerwa nzira dzekukora uyeuremu hwemachira asina kuruka.
Kuyera nzira yezvisina-rukwa machira
Chero chinhu chine huremu, sezvakangoita jira risiri rakarukwa ratiri kutaura nezvaro nhasi. Saka kuti ungaverenga sei huremu hwemucheka usina kuruka?
Muchiverengero chehuremu uye huremu hwemicheka isina kurukwa, zvikamu zvina zvinowanzoshandiswa: imwe iyadhi, yakapfupikiswa seY muchiRungu; Yechipiri mamita, yakapfupikiswa sem, yechitatu magiramu, yakapfupikiswa semagiramu, uye yechina mamirimita, yakadimburirwa semamirimita.
Kuverenga urefu
Nezvekutsanangurwa, zvese saizi nemamita zvinoshandiswa kuverenga urefu. Mukugadzirwa kwemachira asina kuruka, mita inowanzoshandiswa sechikamu chehurefu, uye zviyero zvekuyera zvehurefu zvinosanganisira mamita, masendimita, millimeters, nezvimwewo. Pamusana pekuti micheka isina-yakarukwa inokungurutswa imwe neimwe, kureba kwepumburu kunonzi hupamhi, inoratidzwa mumamita. Madimikira anowanzo shandiswa anowanzo 2.40 metres, 1.60 metres, uye 3.2 metres. Semuenzaniso, mukugadzira jira risiri rakarukwa, imwe neimwe nzira yekugadzira ichave nehurefu hwakananga, se "kugadzira X metres yemucheka usina kuruka mune mumwe muchina wekuumba".
Weight kuverenga
Sezvo paine kureba nehupamhi, pane ukobvu here? Ndizvozvo, zviripo. Zvinoenderana nezviyero zvepasi rose, zvikamu zvekuyera huremu magiramu (g), makirogiramu (kg), zvichingodaro. Mukugadzira machira asiri akarukwa, chiyereso chinowanzoshandiswa magiramu, uye magiramu anoshandiswa kuverenga ukobvu. magiramu anoreva huremu hweskweya giramu, hunova g/m ^ 2. Wadii kushandisa mamirimita? Muchokwadi, mamirimita anoshandiswawo, asi haawanzo kushandiswa. Uyu mutemo weindasitiri. Muchokwadi, huremu hwegiremu huremu hunogona kuenzana nemamirimita mukukora, sezvo huremu hwemachira asiri akarukwa hunobva pa10g/㎡ kusvika 320g/㎡. Kazhinji, kukora kwejira risiri rakarukwa i0.1mm, uye huremu paskweya mita i30g, saka huremu hwemamita zana roll yejira risiri rakarukwa i0.3kg.
Area calculation
Mayuniti akajairwa enzvimbo anosanganisira masikweya mita (square mita), masikweyadhi, masikweya tsoka, zvichingodaro. Mukugadzira, nzira dzekuverenga dzakakosha dzinofanirwa kushandiswa nekuda kwekusiyana kwakakora kwemachira asiri akarukwa. Ukobvu hunowanzo shandiswa hwejira risiri rakarukwa i0.1mm ~ 0.5mm, uye kuverenga kwenzvimbo kunowanzoenderana nehuremu paskweya mita (g/㎡). Semuyenzaniso, kana huremu hweimwe sikweya mita yejira risiri rakarukwa riri magiramu makumi mashanu, saka jira risiri rakarukwa rinonzi 50 gramu jira risiri rakarukwa (rinozivikanwawo se50g/㎡ jira risiri rakarukwa).
Kuoma (kunzwa)/Kubwinya
Parizvino, kune mashoma zviridzwa uye midziyo yekuyedza kuomarara kwemachira asiri akarukwa pamusika, uye anowanzo kuedzwa zvichienderana nekunzwa kweruoko / kupenya.
Thetensile parameters emachira asina kurukwa
Machira asina kurukwa ane longitudinal uye transverse tensile parameters. Kana dzikaitwa zvisina kurongwa, dzakatsikirirwa, dzakasanganiswa uye dzakapfapfaidzwa, mutsauko mukureba uye transverse tensile masimba hauna kukosha.
Pasi pehukuru hwePasi, huremu nehuremu zvakaenzana, asi zvikamu zvekuyera zvakasiyana. Huremu hwechinhu chine huremu hwekirogiramu kana ichiiswa kunze kwesimba re9.8 Newtons hunodaidzwa kuti 1 kilogram huremu. Kazhinji, mayuniti akawanda anowanzo shandiswa pachinzvimbo chehuremu, achipetwa nekuwedzera nekukwira kwegiravhiti. MuChina yekare, jin uye liang zvaishandiswa sezvikamu zvehuremu. Pounds, ounces, carats, nezvimwewo zvinoshandiswawo sezvikamu zvehuremu.
Iwo anowanzo shandiswa zvikamu zvehuremu anosanganisira micrograms (ug), milligrams (mg), magiramu (g), makirogiramu (kg), matani (t), nezvimwe.
Zviyero zvekushandura makesi
1. Nzira yekushandura huremu hwejira kubva ku g/㎡ kuenda ku g/mita?
Zvinhu zvemapango ekushambadzira asiri akarukwa i50g/㎡. Mangani magiramu ezvigadzirwa zvinodikanwa kugadzira jira remamita zana refu risiri rakarukwa? Sezvo iri 50g/㎡ jira risiri rakarukwa, huremu pa 1 sikweya mita magiramu makumi mashanu. Nekuverenga uku, huremu hwe100 square metre jira risiri rakarukwa i50 magiramu * 100 square metres=5000 magiramu=5 kilograms. Naizvozvo huremu hwejira remamita zana kureba risiri rakarukwa i5 kilograms/100 metres=50 gramu/mita.
2. Nzira yekushandura magiramu kune nzvimbo?
Kureba kwejira risiri rakarukwa i1.6m, kureba kwega kwega kunosvika 1500 metres, uye huremu hwemupumburu wega wega 125kg. Nzira yekuverenga sei huremu pamamita mita? Chekutanga, verenga iyo yakazara nzvimbo yemupumburu wega wega wejira risiri rakarukwa. Nzvimbo yedenderedzwa ine dhayamita yemamita 1.6 ndeye π * r ²， Pakati pavo, r = 0.8m, π ≈ 3.14, saka nzvimbo yemupumburu wega wega wejira risiri rakarukwa i3.14 * 0.8 ²≈ 2.01 square metres. Mupumburu wega wega unorema makirogiramu zana nemakumi maviri neshanu, saka huremu paskweya mita i125 magiramu paskweya mita ÷ 2.01 masikweya mita pamupumburu ≈ 62.19 magiramu paskweya mita.
Mhedziso
Ichi chinyorwa chinosuma nzira yekushandura yekuyerwa kwemachira asina kuruka, kusanganisira maverengero enzvimbo, huremu, hurefu, uye zvimwe zvinhu. Mukugadzirwa kwemachira asina kuruka, matambudziko ekuyera anowanzosangana. Chero bedzi nzira yekushandura inowirirana ichishandiswa pakuverenga, mhinduro yakarurama inogona kuwanikwa.
