Nanometer ke eng?

Tlhahiso: Mechine e mengata haholo e e sebelisa

N nanometer (nm) ke boima ba litekanyetso tsa metric, e lekana le limilione tse sekete tsa meter (1 x 10-9 m). E ka 'na eaba ba bangata ba utloile ka eona pele-e atisa ho amahanngoa le nanotechnology le pōpo kapa ho ithuta lintho tse nyenyane haholo. Ho hlakile hore nanometer e nyenyane ho feta meter, empa u ka 'na ua ipotsa hore na e nyane hakae? Kapa, ​​ke mefuta efe ea litsebi kapa lihlahisoa tsa sebele tsa lefatše tse sebetsang ka tekanyo ee ea nanoscopic?

Kapa, ​​hore na e amana joang le litekanyo tse ling tsa methapo ea bolelele?

Kamoo Nyenyane e leng Nanometer?

Litekanyo tsa metric kaofela li thehiloe ho meter. Hlahloba 'musi leha e le ofe kapa tepi ea tekanyo,' me o ka bona letšoao le bontšitsoeng bakeng sa limithara, lik'hilograma le millimeters. Ka letsoho la pente le letsoho le tsitsitseng, ha ho thata ho hula mela e le 'ngoe feela. Joale ak'u nahane ho leka ho finyella limilione tse limilione tse ka bang limililimithara- ke nanometer. Ho etsa joalo ho tla hloka lisebelisoa tse khethehileng ho tloha:

• N nanometer (nm) e nyane ho feta ..

• micrometer (μm), e nyane ho feta ..

• millimeter (mm), e nyenyane ho feta ..

• cmense (cm), e nyenyane ho feta ..

• decimeter (dm), e nyenyane ho feta ..

• methara (m)

Ntle le thuso ea lisebelisoa leha e le life (mohlala, ho khabisa likhalase, li-microscopes), leihlo le tloaelehileng la motho (e leng pono e tloaelehileng) le khona ho bona lintho ka bomong hoo e ka bang makholo a mabeli a limilimithara tse le bophara, e lekanang le micrometer tse 20.

Ho fana ka boholo ba micrometer tse 20 moelelo oa taba, bona hore na u ka tseba k'honthinente e le 'ngoe / acrylic e tsoelang pele ho tsoa mokotong (ho e boloka khahlanong le mohloli o khanyang o tla thusa haholo) kapa ho phaphamala moeeng joaloka lerōle. Kapa u hloekise lehlabathe le letle letsohong la letsoho la hao ho fumana lijo tse nyane ka ho fetisisa tse sa utloisisoeng.

Haeba tseo li le thata ho li etsa, sheba moriri oa batho ho e-na le hoo, o ka bang 18 micrometer (hantle haholo) ho ea ho li-micrometer tse 180 (bophahamo bo boholo).

'Me tsohle tse mpa e le karolo ea micrometer feela - lintho tse boholo ba nanometer li na le likete tse sekete!

Liathomo le Lisele

Hangata nanoscale e akaretsa boholo ba nanometer e le 'ngoe, e akarelletsang ntho e' ngoe le e 'ngoe ho tloha maemong a atomic ho ea lisele. Li-virus li na le li-nanometer tse 50 le tse 200 ka boholo. Boima ba khanya ea sele e pakeng tsa nanometer tse 6 le li-nanometer tse 10. Helix ea DNA e na le li-nanometer tse peli, 'me carbon nanotubes e ka ba e nyenyane joaloka nanometer e le' ngoe.

Ho bonolo ho utloisisa hore e hloka lisebelisoa tse phahameng tse nang le matla a marang-rang (mohlala, ho senya li-microscopes) ho sebelisana le (e leng setšoantšo, tekanyo, mohlala, ho sebetsa, le ho etsa) lintho ka tekanyo ea nanoscopic. Hape ho na le batho ba etsang sena letsatsi le letsatsi likarolong tse kang:

• Khemistri

• Biology

• Fizikia

• Lisebelisoa tsa Saense

• Boenjiniere

• Theknoloji

Ho na le mehlala e mengata ea lihlahisoa tsa morao-rao tse entsoeng ka nanometer. Meriana e meng e nyenyane e etselitsoe ho khona ho fetisetsa lithethefatsi ho lisele tse itseng. Lik'hemik'hale tsa mehleng ea kajeno li entsoe ka mokhoa o etsang limolek'hule ka ho nepahala ha nanometer.

Li-nanotubes tsa carbon li sebelisoa ho ntlafatsa thepa ea motlakase le motlakase ea lihlahisoa. Le smartphone ea Samsung Galaxy S8 le tablet ea Apple iPad Pro (bobeli-gen-gen) bobeli ba likarolo tse entsoeng ka 10 nm.

Bokamoso bo na le boitsebiso bo eketsehileng bakeng sa li-science-based siometer-applications le lisebelisoa tsa theknoloji. Leha ho le joalo, nanometer hase esita le tekanyo e nyenyane ka ho fetisisa! Sheba tafoleng e ka tlase ho bona kamoo e bapisang kateng.
