Laba saacadood, qiimo isku mid ah - hal garaac oo caadi ah, hal garaac oo dhaldhalaal ah oo gacanta lagu rinjiyeeyay, iyo farqi kun-yuan ah. Xaggee ayuu farqigu ka yimaadaa? Tilmaamahan wuxuu soo bandhigayaa dhaqaalaha saacadaha dhaldhalaalka: galaaska macdanta ah ee la shiiday ilaa budada aadka u fiican, oksaydhyada birta ah ee lagu daray muraayadaha, iyo garaacyada oo lagu shiday 800-1000°C halkaas oo hal cillad ay ka baxdo qaybta oo dhan. Iyadoo heerka cilladdu uu ka sarreeyo 60% dhaldhalaalka gacanta lagu sameeyay marka loo eego wax ka yar 5% garaacyada daabacan, macquulka kharashku wuu caddaadaa. Waxaan sidoo kale shaaca ka qaadaynaa sida tignoolajiyada dhaldhalaalka ee casriga ah ee heerkulka hooseeya ay farsamadan kunka sano ah u keentay meelaha qiimaha raaxada ee la heli karo, sida loo ogaado garaacyada been abuurka ah ee daabacan, iyo marka garaaca caadiga ah ee la xardhay uu yahay iibsiga caqliga badan. Sheekada gudaha ee farshaxanka dhaldhalaalka ee ugu quruxda badan - uguna jilicsan - ee sameynta saacadaha.

Saacadaha jadwalka oo dhammaystiran, kuwa sannadlaha ah, iyo kuwa joogtada ah dhammaantood waxay soo bandhigaan taariikhda, maalinta, iyo bisha, laakiin aad bay ugu kala duwan yihiin kakanaanta iyo soo noqnoqoshada hagaajinta. Jadwalka oo dhammaystiran wuxuu qaataa bilo 31 maalmood ah wuxuuna u baahan yahay 5 hagaajin sannadkii. Jadwalka sannadlaha ah wuxuu aqoonsan yahay bilo 30 iyo 31 maalmood ah laakiin ma aha dhererka Febraayo - wuxuu u baahan yahay hal hagaajin dhammaadka Febraayo. Jadwalka joogtada ah si toos ah ayuu u xisaabiyaa sannadaha boodboodka, bilaha gaaban, iyo xitaa xeerarka qarniga, isagoo aan u baahnayn wax hagaajin ah inta lagu jiro isticmaalka caadiga ah. Maqaalkani wuxuu kala saarayaa nooc kasta.
