Igiti - ibintu bihendutse, ibikoresho byangiza ibidukikije, bikoreshwa cyane mubwubatsi no kurangiza inyubako. Ariko, benshi baramwanze kubwimpamvu yimpamvu yintwaro itangiye kororoka, ibice bigaragara muburyo. Bibaho nkibiti byumye. Urashobora kwirinda ikibazo nkiki uramutse ukorana nibintu byumye. Ibiti byubushuhe bigengwa ninyandiko nyinshi, byumwihariko snip II-25-80.
Kugirango ubone imiterere yo mu rwego rwo hejuru kandi yizewe, birakenewe gukoresha mugihe cyo kubaka inkwi gusa.
Ariko nigute ushobora kumenya ubushuhe bwibiti mugihe ugura? Ku jisho biragoye rwose kumenya. Gusa inzobere hamwe nubunararibonye bwagutse mubimenyetso bimwe birashobora kumenya ibiti bito bito cyangwa byumye, ariko ntibizatanga igipimo cyuzuye cyinyungu. Imyanzuro imwe yerekeye ubushuhe irashobora gukorwa mugihe cyo gutunganya ibiti. Niba chip ikuweho plastiki kandi ikananama, noneho inkwi ni mbisi, niba isenyutse - yumye. Ibipimo byubwubatsi bisaba imibare nyayo, kandi kubisobanuro byayo hari uburyo bukoreshwa cyane bukoreshwa nuburemere no kubara ukoresheje igikoresho cyihariye - metero yubushuhe.
Kubara ubushuhe bwibiti na misa
Igishushanyo 1. Imbonerahamwe yubusa bwubwoko butandukanye bwibiti.
Birazwi ko amoko atandukanye yibiti afite ubucucike butandukanye. Ariko ubucucike buterwa gusa nubwoko gusa, ahubwo buturuka ku bushuhe bw'ibiti: igihugu cy'inkwi, ni byoroha. Amakuru kuri moko zisanzwe zitangwa mumeza kumeza 1. Kumenya ingano na misa, ukishakira ubucucike, ugibone kumeza hanyuma ukagena ubuhehere bwinkwi. Ubu ni inzira yoroshye kandi yihuta yo kumenya ubushuhe. Ariko, bigomba kwitwarikanwa ko ubucucike bwibiti byabandi, ariko bikura mubice bitandukanye byikirere, birashobora gutandukana, nuko amakosa yo kubara atazirindwa.
Ingingo ku ngingo: kwerekana neza igisenge mumodoka
Ushaka kumenya neza ubushuhe bwo kwibeshya, ubushakashatsi bukorwa. Kubizamini, icyitegererezo cyafashwe mubunini 20x20x30. Ikizamini cyaciwe nigiti cya Sawre kuri byibuze 30-50 cm kuva ku nkombe yinama. Yapimwe ku munzani ufite ukuri 0.1 g kandi ashyirwa mu bushyuhe bwa 101-104 ° C. Nyuma yamasaha 6, icyitegererezo kiva mu nama y'abaminisitiri, yongeye gupimwa no gushirwa kuri Inama y'Abaminisitiri. Gupima gupima bikorwa hamwe namasaha 2. Gupima ibisubizo. Niba itandukaniro rya misa kubyavuye mubyavuye mu bipima bibiri bitarenza 0.1 g, noneho ibiti bifatwa nkibyungu rwose.
Kubara ibiti byimbaho.
Ubushuhe bwuzuye bwibikoresho bubarwa na formula:
W = (m-m0) / m0 × 100 (%),
Aho W ni ubuheya, m ni urugero rwa misa hamwe nicyitegererezo cya mbere, M0 ni misa yicyitegererezo kimwe nyuma yuruzu rwuzuye.
Birakenewe gusuzuma uburyo bwo kumenya icyitegererezo cyurugero. Birashobora gutekereza ko yapima 98.76 g gukama, nyuma yo gukama - 65.81, hanyuma w = (986-65.81) / 65,81x100 = 50.1%.
Kugirango ubone ibisubizo byizewe, birakenewe kwiga hamwe ningero nyinshi. Ntabwo bisabwa kwihanganira mu gitamwagu cyumye cyamasaha arenga 20 yintangarugero.
Ubu buryo bwo kugena ubuhehere bwibiti bihuye na gost 16483.7-71, ariko bisaba igihe kinini kandi bisaba ibikoresho byihariye bya laboratoire.
Kugena ubushuhe hamwe na metero nziza
Kugirango umenye ibikubiye mubiti, urashobora gukoresha metero yubushuhe.
Iterambere rya siyansi na tekiniki, rigaragara muburyo bwose bwibikorwa byabantu, ntibyagumye ku ruhande no kubaha ikibazo nkiki cyo kumenya ubushuhe. Muri iki gihe, metero nziza ntigitangara. Igiciro cyiki gikoresho cyimukanwa giterwa nuwabikoze, icyitegererezo no gushyiraho imikorere, ariko ntabwo ari hejuru yo kureka iki gikoresho cyoroshye. Metero yubushuhe ni ububiko ubwo aribwo bwose aho ibiti bibitswe cyangwa bigurishwa. Kubwibyo, igipimo cyubushuhe gihinduka urubanza rwiminota.
Ingingo ku ngingo: Ubwoko, inzira zo gukata Windows
Ihame ryo gukora metero yubushuhe rishingiye ku gupima irwanya igihe umuyaga w'amashanyarazi wanyuze mu giti. Igikoresho gifite urushinge rwabashishoza rwacometse mu biti bya Sawwn ku fibre. Iyo ukanze buto yo gupima, ikigezweho cyanyuze muri bo, kandi ibisubizo bimaze guhindurwa mubusarure buhita bwerekanwe kubigaragaza. Ikosa ryo gupima mugukora ubushuhe bwa none ntirirenze 1.5%. Bikwiye gusobanuka ko ibisubizo byizewe gusa ahantu ho gukenera. Gucira imanza igiti cya Sawre muri rusange, ni ngombwa gufata ibipimo byinshi bishoboka muburebure nubugari bwinama y'Ubutegetsi.
Ibipimo byemewe byubushuhe bwibiti ukurikije urugendo.
Umubare munini wa moderi ifite umuyobozi muremure uhuza igikoresho hamwe na sensor. Ibi biragufasha gupima ubushuhe bwibiti kure iyo byumye mucyumba. Muri icyo gihe, sensor yinjijwe mu mbaho ziri hagati yikibanza. Igikoresho ubwacyo gishyirwa hanze yurugereko. Iyo ibipimo, birakenewe gukosorwa ubushyuhe. Uburyo bwa kure buroroshye kugenzura inzira yo kumisha ibiti, ariko igomba kumenyekana ko akenshi itanga ibisubizo bigoretse. Ibi biraba kubwimpamvu ebyiri: Bitewe no gushyushya inshinge za sensor, zituma inshinge zayo zirimo ahantu hafunga, kandi kubera imvururu zidahuye cyane ni inkwi.
Mugihe aho bitifuzwa cyane ndetse no kwangirika ntarengwa kubiti, kurugero, niba turimo tuvuga ibisobanuro birambuye kubikoresho, birashoboka kugena ubuhehere bwibiti birashobora kuba metero yubuhanga. Ntabwo ifite urushinge, ahubwo ikoreshwa gusa hejuru yimbaho. Ihame ryibikorwa byigikoresho rishingiye ku gupima uburebure bwamateka ya electromagnetic, kizaba gitandukanye bitewe nubushuhe. Mugihe upima, Meter yubushuhe agomba kumenya inkwi mubwoko.
Kuma ibiti
Ibiti bitose - ntabwo ari interuro. Irashobora kuzanwa muburyo bukwiye ndetse no gukama mucyumba. Byongeye kandi, gukama ikirere birasabwa kubiti byose byaguzwe.
Kuma ibiti bigabanuka mububiko bwukuri. Kubwibyo, ifite ahantu hagenewe umushinga, urinzwe nigitereko cyimvura nizuba ryizuba. Imiterere yanyuma biterwa nuko munsi yizuba, ubuso bwimbaho bushyushye bukama kandi bwumye, kandi hepfo iracyari itose. Kubera iyo mpamvu, voltage ibaho, inkwi zirarenze kandi zigace.
Ingingo ku ngingo: Gushiraho interlight yagarukiye mu gikoni n'amaboko yabo
Ibikoresho byashyizweho na lags hamwe nuburebure bwa byibuze 0.5 kuva kurwego rwubutaka. Ubuso buse bugomba kugira icyerekezo gikabije. Kugira ngo wirinde gutandukana kw'ikibaho, intera iri hagati yingingo zidakwiye kurenga 1.5 m. Hagati yimirongo yimbeho perpendicular kuri bo harimo uburebure bwa mm 25-40, na nyuma ya 1.0-1.5 m - imirongo minini muri 100- 150 mm. Ibi bizatanga ikwirakwizwa ryiza. Ntushobora kubikwa ku cyicaro kimwe cyimiti, ufite ubushuhe butandukanye: Hygroscopique, ibiti byinkwi, kandi ibiti byumye bizapfunyika kuva bitose.
Igihe gisabwa cyo kumisha ikimenyetso cya 18-22% yubushuhe buratandukanye kuva kumigero 9 kugeza 40. Biterwa nikirere, igihe cyumwaka nubwinshi bwibikoresho.
