Degree Laabashada: 2mm / M;
Jaban: Jiirada: dekedda biibiile birta ah waa inay buuxisaa shuruudaha jadwalka soo socda.
Ⅱ. Habka Xisaabinta Miisaanka
Tuubada birta ahama waxay guud ahaan loo geeyay iyadoo loo eegayo culeyska teori, sidoo kale waxaa lagu geyn karaa iyadoo loo eegayo culeyska dhabta ah gorgortanka ka dib. Marka loo dhiibo iyadoo loo eegayo culeyska fekerka, culeyska fekerka waxaa loo xisaabiyaa iyadoo lagu saleynayo qaaciddada (I)

Qaabka Birta ahama
- Tuubbada ayaa inta badan ah tuubbo alwaax ama tubbo qaabeed ah, guud ahaan loo isticmaalo gacan-qabsi ama qurxin, kuwaas oo qalabkoodu guud ahaan yahay 304 bir bir ah ama ka fiican. Habka wax soo saarku waa tuubada qaabka ugu horaysa u riixaysa xariga birta ah, ka dibna guud ahaan alxanka guud, iyo ugu dambeyntiina xoqida iyo nadiifinta.
- Guud ahaan waa qaab dheeman ama qaab wareeg ah, qaadashada xarig-xardho bir ah iyo gariiradda bir sameynta alxanka.
Dhexroorkeedu guud ahaan waa 22mm-48mm, codsi muhiim ah: qurxinta guriga, jaranjarada jaranjarada cuskado, gacmaha tuubooyinka, gawaarida gacmaha, iwm.

Ahama tubbada birta ahama, darbiga tubada darbiga, tubbada cusbo ee naafada
Badeecadani waxay leedahay qaab dhismeed cusub iyo tikniyoolajiyad hoggaamineed. Marka loo eego astaamaha gacan-qabsiga, isku-darka dabiiciga ah ee ridaya iyo tuubbada ayaa xaqiijineysa in gacan-qabsi uu leeyahay awood sare iyo khadadka dusha sare ee siman. Nidaamka kala-jajabinta gacan-ku-haynta ayaa xallinaya dhibaatada in geesaha qaarkood ka dib alxanka alxanka aan lagu daaweyn karin dusha sare. Marka loo eego shuruudaha farsamada, dusha sare ee gacan-qabsiga waxaa lagu daaweyn karaa burush, ciida ka-dillaaca, kala-goynta, rinjiyeynta buufin, iyo wax taaj oo kale buufin. Ka dib, dusha sare waxaa lagu daaweeyaa habka gaarka ah ee ka hortagga wasakheynta, taasoo ka dhigeysa muuqaal qurux badan, oo aan lahayn saliid iyo fududahay in la nadiifiyo. Nidaamka alxanka gaarka ah ee sameynta gacan-qabsiga waxaa laga kormeerayaa dhinacyada howlgalka, qalabka, iyo cabbiraadaha geedi socodka si loo hubiyo tayada alxanka.
