Farqiga u dhexeeya silsiladda 12B iyo silsiladda 12A

1. Qaabab kala duwan

Farqiga u dhexeeya silsiladda 12B iyo silsiladda 12A ayaa ah in taxanaha B uu yahay mid boqortooyo ah isla markaana waafaqsan qeexitaannada Yurub (badanaa Ingiriiska) guud ahaanna loo isticmaalo waddamada Yurub; taxanaha A macnaheedu waa halbeeg wuxuuna waafaqsan yahay qeexitaannada cabbirka ee heerarka silsiladda Mareykanka waxaana guud ahaan loo isticmaalaa Mareykanka iyo Japan iyo waddamada kale.

2. Cabbirro kala duwan

Heerka labada silsiladood waa 19.05MM, cabbirrada kalena way kala duwan yihiin. Cutubka qiimaha (MM):

Xuduudaha silsiladda 12B: dhexroorka duubku waa 12.07MM, ballaca gudaha ee qaybta gudaha waa 11.68MM, dhexroorka usha biinka waa 5.72MM, dhumucda saxanka silsiladdana waa 1.88MM;
Xuduudaha silsiladda 12A: dhexroorka duubku waa 11.91MM, ballaca gudaha ee qaybta gudaha waa 12.57MM, dhexroorka usha biinka waa 5.94MM, dhumucda saxanka silsiladdana waa 2.04MM.

3. Shuruudaha qeexitaannada kala duwan

Silsiladaha taxanaha A waxay leeyihiin saami gaar ah oo ku saabsan duubayaasha iyo biinanka, dhumucda saxanka silsiladda gudaha iyo saxanka silsiladda dibadda waa isku mid, saameynta xoogga isku midka ah ee xoogga taaganna waxaa lagu helaa hagaajin kala duwan. Si kastaba ha ahaatee, ma jiro saami cad oo u dhexeeya cabbirka ugu weyn iyo heerka qaybaha taxanaha B. Marka laga reebo qeexitaanka 12B ee ka hooseeya taxanaha A, qeexitaannada kale ee taxanaha B waxay la mid yihiin alaabada taxanaha A.
