Kugereranya imiterere n'ibikorwa hagati y'ivyuma vy'ibara ry'agahama n'ibara ry'umubiri risanzwe
(1) ibiranga imiterere
(1) inzira y'umurongo w'umugozi n'igice c'umurongo w'amapine Angle ni 0 impapuro z'umutsindo
(ni ukuvuga, Angle ifise umurongo wo hagati w’igitereko ni degre 90).Iyi ntunganyo y’umugozi isa cane n’iyi meridian y’umupira (ni ukuvuga meridian), yitwa ipine ya meridian.Inyuma y’umurongo w’igitutu, gutuma uburemere bw’umurongo w’igitutu c’umugozi w’ibara ry’umugozi w’ibara ry’umugozi ari muto cane 40%. 50% .Bigeze gusa 1-4 ibipande, ipine y'imirongo muri rusangi gusa igice c'impuzu,
Cord hagati y’umupira gusa kugira ngo ugume ukorana mu nzira y’uruziga.Biranduye guhangana n’inguvu nini z’inzira, ziterwa n’ipine y’imirongo ifata igipimo c’imirongo myinshi, kinini (Igipande n’igice c’ivyuma c’ibipimo vya 70-75 regrates), inkomezi zikomeye, ntiziroshe kurambura nk’igice c’ivyuma gifise umurongo w’umurongo (na co nyene kizwi nk’igipande gikomeye canke c’ivyuma. igitsibo, nk'umurongo ukomeye, ufatanye ku ruzitiro (3) igice c'ipine y'ibara ry'agahama ni kinini, igice c'umusaraba c'igipimo (H/B) co kwiruka 0.7.
(2) ibiranga ibikorwa
Ugereranije n’ipine ry’ibintu bisanzwe, rifise ubushobozi bwo gutera imbere n’ubushobozi bwo kwambara neza (bishobora kwongerwako 30%-50.M-n’ubudahangarwa bw’ugutembagazwa (bishobora kugabanya ugukoresha amavuta y’imodoka nk’8%), ubushobozi bwiza bwo gufata (mu nzira y’ibitovu ntivyoroshe gunyerera), ubushobozi bwo kwikorera, ntibworoshe gutobora, ubushobozi bwiza bwo gukora, bushobora gutuma neza neza uburyo bwo gukoresha ivyuma vy’amazi.{4}} Ivyago ni: uruhande rw’ipine rworoshe guca, kubera uguhinduka kw’isonga, bikaba bituma habaho ugushikama kw’inyuma kw’ibati ni bibi, ibisabwa vy’ubuhinga bwinshi, igiciro kinini{5}}
Mu gukoresha, ni vyiza gushiramwo amapine y’imirongo, canke gukoresha wenyene ku kiraro c’inyuma, ariko ntigishobora gukoresha amapine y’imirongo gusa ku kiraro c’imbere, ikiraro c’inyuma gifise amapine asanzwe, na co nyene ntigishobora kuvangwa n’amapine asanzwe y’ugushira ahabona .
