H Beam (HEA HEB) oo leh cabbirro bir ah oo qaabaysan EN H
HABKA SOO SAARKA ALAABTA
Habka wax soo saarka ee birta H-qaabaysan ee dibadda ah badanaa waxaa ka mid ah tallaabooyinka ugu muhiimsan ee soo socda:
Diyaarinta alaabta ceeriin ah: Alaabada ceeriin ee wax soo saarkaBirta qaabka H-qaabaysanbadanaa waa billet bir ah. Billet-ka birta ah wuxuu u baahan yahay in la nadiifiyo oo la kululeeyo si loo farsameeyo loona sameeyo.
Habaynta duubista kulul: Billet-ka birta ah ee la kululeeyay waxaa loo diraa warshadda duubista kulul si loogu farsameeyo. Warshadda duubista kulul, billet-ka birta ah waxaa lagu rogrogaa rogorro badan ka dibna si tartiib tartiib ah ayuu u samaysmaa qaabka isgoyska ee birta qaabka H.
Shaqeyn qabow (ikhtiyaar ah)Xaaladaha qaarkood, si loo hagaajiyo saxnaanta iyo tayada dusha sare ee birta qaab-H ah,Birta kulul ee loo yaqaan 'H-shaped'sidoo kale waa la farsameyn doonaa qabow, sida duubista qabowga, sawirista, iwm.
Jarida iyo dhammaystirka: Ka dib marka la rogo oo la qabto shaqada qabow, birta qaab-H ah waa in la jaro oo la dhammeeyaa iyadoo la raacayo shuruudaha macaamiisha si loo daboolo shuruudaha cabbirka iyo dhererka gaarka ah.
Daaweynta dusha sare: Daawaynta birta qaabka H-qaabaysan oo nadiif ah oo ka hortagta miridhku si loo hubiyo tayada dusha sare iyo iska caabbinta miridhku ee badeecada.
Kormeerka iyo baakadaynta: Samee kormeer tayo leh oo ku saabsan birta qaabka H-ga ah ee la soo saaray, oo ay ku jiraan kormeerka tayada muuqaalka, saxnaanta cabbirka, sifooyinka farsamada, iwm. Ka dib marka la dhammeeyo imtixaanka, waa la xirxiri doonaa oo diyaar u ah in loo diro macaamiisha.
