Waa maxay Dhammaystirka Dusha sare? Waa maxay macnaha 3.2 oogada sare?

Ka hor inta aynaan u gelin shaxda dhammaystirka dusha sare, aynu fahanno waxa dhammaystirka dusha sare ka kooban yahay.
Dhamaystirka dusha sare waxa loola jeedaa habka wax ka beddelka birta dusheeda taas oo ku lug leh saarista, ku darista, ama dib u qaabaynta. Waa cabbir dhammaystiran oo ka samaysan oogada alaabta taas oo lagu qeexay saddex sifo oo qallafsanaan, mashxarad iyo jiif.

Qalafsanaanta dusha sare waa cabbirka wadarta khaladaadka bannaan ee dusha sare. Mar kasta oo mashiinnadu ay ka hadlaan "dhamaadka dusha sare," waxay inta badan tixraacaan qallafsanaanta dusha sare.
Waviness waxaa loola jeedaa dusha rogman oo kala fogaanshuhu ka weyn yahay dhererka qallafsanaanta oogada. Layna waxa ay tilmaamaysaa jihada qaabka dusha sare u qaadanayo. Mashiinnadu waxay inta badan go'aamiyaan jiifka hababka loo isticmaalo dusha sare.

 

 

Waa maxay macnaha 3.2 oogada sare?

Dhammaystir 32 ah oo dusha sare ah, oo sidoo kale loo yaqaano dhammayn 32 RMS ah ama dhammayn 32 mikroinji ah, waxa loola jeedaa qallafsanaanta dusha sare ee shay ama badeecad. Waa cabbiraadda celceliska kala duwanaanshaha dhererka ama weecashooyinka ku jira qaabka dusha sare. Marka la eego 32 dusha sare ah, kala duwanaanshaha dhererka ayaa caadi ahaan ku wareegsan 32 microinches (ama 0.8 micrometers). Waxay tusinaysaa oog siman oo leh qaab-dhismeed fiican iyo cilladaha ugu yar. Tirada hoose ee nambarada, ayaa ka sii fiican oo jilicsan dhammaadka dusha sare.

Waa maxay RA 0.2 dusha sare

Dhammaadka dusha sare ee RA 0.2 waxaa loola jeedaa cabbir gaar ah oo qallafsanaanta dusha sare. "RA" waxay u taagan tahay celceliska qallafsanaanta, kaas oo ah halbeeg loo isticmaalo in lagu qiyaaso qallafsanaanta dusha. Qiimaha "0.2" wuxuu u taagan yahay celceliska qallafsanaanta mikromitir (µm). Si kale haddii loo dhigo, dhammaystirka dusha sare oo leh RA qiimihiisu yahay 0.2 µm waxay muujineysaa qaab-dhismeed aad u siman oo fiican. Noocan ah dhamaystirka dusha sare waxaa sida caadiga ah lagu gaaraa mashiin sax ah ama habsocod turxaan bixin ah.
