Kuwerengera kulemera kwa nsalu yopanda nsalu

Nsalu zosalukidwa zilinso ndi njira zawo zoyezera makulidwe ndi kulemera kwake. Kawirikawiri, makulidwe amawerengedwa mu millimeters, pamene kulemera kwake kumawerengedwa mu kilogalamu kapena matani. Tiyeni tione mwatsatanetsatane njira kuyeza makulidwe ndikulemera kwa nsalu zopanda nsalu.

Njira yoyezera nsalu zopanda nsalu

Chinthu chilichonse chimakhala ndi kulemera, monganso nsalu yopanda nsalu yomwe tikukamba lero. Ndiye momwe mungawerengere kulemera kwa nsalu zopanda nsalu?

Powerengera kulemera ndi kulemera kwa nsalu zopanda nsalu, mayunitsi anayi amagwiritsidwa ntchito kawirikawiri: imodzi ndi bwalo, yofupikitsidwa monga Y mu Chingerezi; Chachiwiri ndi mamita, chofupikitsidwa ngati m, chachitatu ndi magalamu, chofupikitsidwa ngati magalamu, ndipo chachinayi ndi mamilimita, chofupikitsidwa monga mm.

Kuwerengera kutalika

Potengera kutsimikizika, kukula ndi mita zonse zimagwiritsidwa ntchito powerengera kutalika. Popanga nsalu zopanda nsalu, mita nthawi zambiri imagwiritsidwa ntchito ngati gawo la kutalika, ndipo miyeso yoyezera kutalika imaphatikizapo mamita, centimita, millimeters, ndi zina zotero. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala 2.40 metres, 1.60 metres, ndi 3.2 metres. Mwachitsanzo, popanga nsalu zopanda nsalu, njira iliyonse yopangira idzakhala ndi kutalika kwake, monga "kupanga X mamita a nsalu zopanda nsalu mu makina amodzi opangira".

Kuwerengera kulemera

Popeza pali utali ndi m'lifupi, pali gawo la makulidwe? Ndiko kulondola, alipo. Malinga ndi miyezo yapadziko lonse lapansi, mayunitsi oyezera kulemera ndi magalamu (g), kilogalamu (kg), ndi zina zotero. Popanga nsalu zosalukidwa, gawo lolemera lomwe limagwiritsidwa ntchito kwambiri ndi magalamu, ndipo magalamu amagwiritsidwa ntchito powerengera makulidwe. magalamu amatanthawuza kulemera kwa sikweya gramu, komwe ndi g/m ^ 2. Bwanji osagwiritsa ntchito mamilimita? Ndipotu, mamilimita amagwiritsidwanso ntchito, koma sagwiritsidwa ntchito kawirikawiri. Ili ndi lamulo lamakampani. M'malo mwake, kulemera kwa gramu ya sikweya kumatha kukhala kofanana ndi mamilimita mu makulidwe, popeza kulemera kwa nsalu zopanda nsalu kumachokera ku 10g/㎡ mpaka 320g/㎡. Kawirikawiri, makulidwe a nsalu zopanda nsalu ndi 0.1mm, ndipo kulemera kwa mita imodzi ndi 30g, kotero kulemera kwa mpukutu wa mita 100 wa nsalu zopanda nsalu ndi 0.3kg.

Kuwerengera kwadera

Magawo odziwika bwino amderali amaphatikiza masikweya mita (square mita), masikweya mita, masikweya mita, ndi zina zambiri. Popanga, njira zapadera zowerengera ziyenera kugwiritsidwa ntchito chifukwa cha makulidwe osiyanasiyana a nsalu zosalukidwa. Makulidwe omwe amagwiritsidwa ntchito kwambiri pansalu yosalukidwa ndi 0.1mm ~ 0.5mm, ndipo kuwerengera kwa deralo nthawi zambiri kumatengera kulemera kwa mita imodzi (g/㎡). Mwachitsanzo, ngati kulemera kwa sikweya mita imodzi ya nsalu zosalukidwa ndi magalamu 50, ndiye kuti nsalu yosalukidwa imatchedwa 50 magalamu osapanga nsalu (yomwe imadziwikanso kuti 50g/㎡ nsalu yosalukidwa).

Kuuma (kumva)/Kunyezimira

Pakalipano, pali zida ndi zida zochepa kwambiri zoyesera kuuma kwa nsalu zosalukidwa pamsika, ndipo nthawi zambiri zimayesedwa pogwiritsa ntchito manja / gloss.

Themagawo olimba a nsalu zopanda nsalu

Nsalu zosalukidwa zimakhala ndi nthawi yayitali komanso yopingasa. Ngati iwo amakokedwa mosadziwika bwino, kukanikizidwa, kusakanikirana ndi kupopera mbewu mankhwalawa, kusiyana kwa mphamvu zotalika komanso zopingasa sikofunikira.

Pansi pa mphamvu yokoka ya Dziko lapansi, kulemera ndi kulemera ndizofanana, koma mayunitsi a muyeso ndi osiyana. Kulemera kwa chinthu chokhala ndi 1 kilogalamu kukakhala ndi mphamvu yakunja ya 9.8 Newtons kumatchedwa 1 kilogram kulemera. Nthawi zambiri, mayunitsi ambiri amagwiritsidwa ntchito m'malo mwa kulemera kwake, mochulukirachulukira ndi mathamangitsidwe amphamvu yokoka. Kale ku China, jin ndi liang ankagwiritsidwa ntchito ngati magawo olemera. Mapaundi, ma ounces, carats, ndi zina zambiri amagwiritsidwanso ntchito ngati mayunitsi olemera.

Magawo omwe amagwiritsidwa ntchito nthawi zambiri amaphatikizapo ma micrograms (ug), milligrams (mg), magalamu (g), kilogalamu (kg), matani (t), ndi zina.

Milandu yosintha miyeso

1. Momwe mungasinthire kulemera kwa nsalu kuchokera ku g/㎡ kukhala g/mita?

Zinthu zamitengo yotsatsa yosalukidwa ndi 50g/㎡. Ndi magalamu angati a zipangizo zomwe zimafunika kuti apange nsalu yotalika mamita 100 yopanda nsalu? Popeza ndi 50g/㎡ nsalu sanali nsalu, kulemera pa 1 lalikulu mita ndi 50 magalamu. Pakuwerengera uku, kulemera kwa nsalu yosalukidwa 100 sikweya mita ndi 50 magalamu * 100 masikweya mita = 5000 magalamu = 5 kilogalamu. Choncho, kulemera kwa nsalu yopanda nsalu yotalika mamita 100 ndi 5 kilograms/100 metres=50 magalamu/mita.

2. Momwe mungasinthire magalamu kudera?

M'mimba mwake mwa nsalu zopanda nsalu ndi 1.6m, kutalika kwa mpukutu uliwonse ndi pafupifupi 1500 metres, ndipo kulemera kwa mpukutu uliwonse ndi 125kg. Kodi kuwerengera kulemera pa lalikulu mita? Choyamba, werengerani dera lonse la mpukutu uliwonse wa nsalu zopanda nsalu. Malo ozungulira okhala ndi mamita 1.6 ndi π * r ², Pakati pawo, r = 0.8m, π ≈ 3.14, kotero dera la mpukutu uliwonse wa nsalu zopanda nsalu ndi 3.14 * 0,8 ²≈ 2.01 mamita lalikulu. Mpukutu uliwonse umalemera ma kilogalamu 125, kotero kulemera kwa mita imodzi ndi 125 magalamu pa lalikulu mita ÷ 2.01 masikweya mita pa mpukutu ≈ 62.19 magalamu pa lalikulu mita.

Mapeto

Nkhaniyi ikuwonetsa njira yosinthira makina oyesa makina osalukidwa, kuphatikiza kuwerengera malo, kulemera, kutalika, ndi zina. Popanga nsalu zopanda nsalu, mavuto oyezera nthawi zambiri amakumana nawo. Malingana ngati njira yosinthira yofananira imagwiritsidwa ntchito powerengera, zotsatira zolondola zitha kupezeka.
