Amalaphu angalukwanga nawo aneendlela zawo zokulinganisa ubukhulu kunye nobunzima. Ngokuqhelekileyo, ubukhulu bubalwa ngeemilimitha, ngelixa ubunzima bubalwa ngeekhilogram okanye iitoni. Makhe sijonge kwiindlela zokulinganisa ezineenkcukacha zobuninzi kunyeubunzima beempahla ezingalukwanga.
Indlela yokulinganisa amalaphu angalukwanga
Nayiphi na into inobunzima, kanye njengelaphu elingalukwanga esithetha ngalo namhlanje. Ngoko ke ubala njani ubunzima belaphu elingalukwanga?
Ekubalweni kobunzima kunye nobunzima beendwangu ezingalukwanga, iiyunithi ezine zisetyenziswa ngokuqhelekileyo: enye yiyadi, ifinyeziwe njenge-Y ngesiNgesi; Eyesibini ziimitha, ishunqulelwe njengo-m, eyesithathu ziigram, ishunqulelwe njengeegrem, eyesine ziimilimitha, ishunqulelwe njenge mm.
Ubude bokubala
Ngokwemigaqo, zombini ubungakanani kunye nemitha zisetyenziselwa ukubala ubude. Kwimveliso yelaphu engalukiweyo, imitha idla ngokusetyenziswa njengeyunithi yobude, kwaye iiyunithi zokulinganisa ubude zibandakanya iimitha, iisentimitha, iimilimitha, njl.njl Iimpawu ezisetyenziswa ngokuqhelekileyo ziimitha ezi-2.40, i-1.60 yeemitha, kunye ne-3.2 yeemitha. Ngokomzekelo, kwinkqubo yokuvelisa indwangu engalukiweyo, inkqubo nganye yokuvelisa iya kuba nobude obuthile, njengokuthi "ukuvelisa i-X yeemitha zendwangu engalukiweyo kumatshini omnye wokubumba".
Ukubala ubunzima
Ekubeni kukho ubude kunye nobubanzi, ingaba iyunithi yobukhulu? Injalo, zikho. Ngokwemigangatho yamazwe ngamazwe, iiyunithi zomlinganiselo wobunzima ziigram (g), iikhilogram (kg), njl.njl. Kwimveliso yelaphu elingalukwanga, iyunithi yobunzima obusetyenziswa ngokuqhelekileyo ziigram, kwaye iigram zisetyenziselwa ukubala ubukhulu. iigrem zibhekisa kubunzima begrem, obuyig/m ^ 2. Kutheni ungasebenzisi iimilimitha? Enyanisweni, iimilimitha zikwasetyenziswa, kodwa azifane zisetyenziswe. Lo ngumthetho weshishini. Enyanisweni, ubunzima begram yesikwere bunokulingana neemilimitha kubukhulu, njengoko ubunzima bamalaphu angalukwanga busuka kwi-10g/㎡ ukuya kwi-320g/㎡. Ngokubanzi, ubukhulu belaphu elingalukwanga yi-0.1mm, kwaye ubunzima ngemitha yesikwere yi-30g, ngoko ke ubunzima be-100 yeemitha umqulu welaphu elingalukwanga yi-0.3kg.
Ubalo lwendawo
Iiyunithi eziqhelekileyo zendawo ziquka i-square metres (iimitha ezisisikwere), iiyadi zesikwere, iinyawo zesikwere, njl. Kwinkqubo yokuvelisa, iindlela zokubala ezikhethekileyo kufuneka zisetyenziswe ngenxa yobunzima obuhlukeneyo beendwangu ezingalukwanga. Ubukhulu obuqhelekileyo obusetyenziswayo belaphu elingalukwanga yi-0.1mm~0.5mm, kwaye ubalo lwendawo lusekwe ngokubanzi kubunzima ngemitha yesikwere (g/㎡). Umzekelo, ukuba ubunzima bemitha enye yesikweri selaphu elingalukwanga ziigram ezingama-50, ilaphu elingalukwanga libizwa ngokuba yi-50 grams yelaphu elingalukwanga (elikwabizwa ngokuba yi-50g/㎡ ilaphu elingalukwanga).
Ukuqina (ukuziva)/Iglosi
Okwangoku, zimbalwa kakhulu izixhobo kunye nezixhobo zokuvavanya ubulukhuni bempahla engalukwanga kwimarike, kwaye ngokubanzi zivavanywa ngokusekwe kwimvakalelo/iglosi yesandla.
Iiparameters tensile zamalaphu angalukwanga
Amalaphu angalukwanga aneeparamitha zobude obunqamlezileyo. Ukuba zitsalwe ngokungaqhelekanga, zicinezelwe, zadityaniswa kwaye zifafazwa, umahluko kwi-longitudinal kunye ne-transverse tensile forces awubalulekanga.
Ngaphantsi kobunzima boMhlaba, ubunzima kunye nobunzima bulingana, kodwa iiyunithi zokulinganisa ziyahluka. Ubunzima bento enobunzima obuyikhilogram e-1 xa iphantsi kwamandla angaphandle ayi-9.8 Newtons ibizwa ngokuba yikhilogram enye. Ngokubanzi, iiyunithi zobunzima ziqhele ukusetyenziswa endaweni yobunzima, ziphindaphindwe ngokungafihlisiyo ngokunyuka komxhuzulane. Kwi-China yamandulo, i-jin kunye ne-liang zazisetyenziswa njengeeyunithi zobunzima. Iiponti, ii-ounces, iikharati, njl njl. nazo zisetyenziswa njengeeyunithi zobunzima.
Iiyunithi ezisetyenziswa ngokuqhelekileyo zobunzima ziquka iimicrograms (ug), milligrams (mg), grams (g), kilograms (kg), tons (t), njl.
Iimeko zokuguqulwa komlinganiselo
1. Ukuguqula njani ubunzima belaphu ukusuka kwi-g/㎡ ukuya kwi-g/imitha?
Izinto zeepali zentengiso ezingalukwanga yi-50g/㎡. Zingaphi iigram zemathiriyeli ekrwada ezifunekayo ukuvelisa ilaphu elingalukwanga leemitha ezili-100 ubude? Njengoko ililaphu elingalukwanga eliyi-50g/㎡, ubunzima nge-square meter nganye yi-50 grams. Ngolu balo, ubunzima belaphu elingalukwanga eliyi-100 leemitha ezisikweri ngama-50 grams * 100 square metres=5000 grams=5 kilograms. Ngoko ke, ubunzima belaphu elingalukwanga leemitha ezili-100 ubude buzikhilogram ezi-5/100 yeemitha=50 grams/imitha.
2. Indlela yokuguqula iigram ukuya kwindawo?
Ububanzi belaphu elingalukwanga yi-1.6m, ubude bomqulu ngamnye bumalunga ne-1500 yeemitha, kwaye ubunzima bomqulu ngamnye yi-125kg. Indlela yokubala ubunzima ngemitha yesikwere? Okokuqala, bala indawo epheleleyo yomqulu ngamnye welaphu elingalukwanga. Indawo esetyhula enobubanzi obuziimitha eziyi-1.6 yi-π * r²， Phakathi kwazo, r=0.8m, π ≈ 3.14, ngoko ke indawo yomqulu ngamnye welaphu elingalukwanga yi-3.14 * 0.8 ²≈ 2.01 square metres. Umqulu ngamnye unobunzima beekhilogram ezili-125, ngoko ubunzima kwimitha yesikwere yi-125 grams ngemitha yesikwere ÷ 2.01 imitha yesikwere ngomqulu ≈ 62.19 grams ngemitha yesikwere.
Ukuqukumbela
Eli nqaku lazisa indlela yokuguqula umlinganiselo womatshini welaphu elingalukiweyo, kubandakanywa izibalo zendawo, ubunzima, ubude, kunye neminye imiba. Kwinkqubo yokuveliswa kweendwangu ezingalukwanga, iingxaki zokulinganisa zihlala zidibana. Ngethuba nje indlela yokuguqula ehambelanayo isetyenziselwa ukubala, iziphumo ezichanekileyo zinokufumaneka.
