Ithrekhi yesitimela iwumzila wokugijima omisiwe wesitimela, futhi iyindlela ebaluleke kakhulu yesitimela samanje nobuchwepheshe besitimela. Wonke umuntu bekufanele aqaphele ukuthi ngokuyisisekelo wonke amathrekhi esitimela agqwalile, ngisho namathrekhi esitimela asanda kwakhiwa anje. Imikhiqizo yensimbi egqwalile ngeke nje ifinyeze isikhathi sabo sokuphila, kodwa futhi ibe ntekenteke kakhulu. Pho kungani amathrekhi esitimela engenziwanga ngensimbi engagqwali kodwa ngensimbi egqwalile? Ngemva kokuyifunda, ukhulise ulwazi lwakho.
Ezitimeleni eziningi ezikhona zesitimela, noma kumathrekhi esitimela asakhiwayo, imigqa yethrekhi ehlelwe kahle ingabonakala. Izitimela ezigqwalile kule migqa ziyindida kakhulu, ngoba imikhiqizo yensimbi egqwalile ngenxa yezici zangaphandle izonciphisa izici nemisebenzi yabo. Kungani imikhiqizo enjalo yensimbi ingasetshenziswa ekwakheni izinto zokuhamba ezibalulekile? Asikwazi nje ukusebenzisa izinsimbi zensimbi engagqwali ngokuqondile? Ayigcini nje ngokubukeka iyinhle, kodwa futhi izizwa iphephile futhi inokwethenjelwa. Kodwa okwamanje, lolu hlobo lukaloliwe olugqwalile lufaneleka kakhulu ekwakhiweni kukajantshi, futhi insimbi engagqwali ayilungile njengayo.
I-China njengamanje isebenzisa ojantshi bensimbi abane-manganese ephezulu ekwakheni izinto zokuhamba zikaloliwe. Le nto inezinto eziningi ze-manganese ne-carbon kunensimbi evamile, okwandisa ubulukhuni nokuqina kwamareyili ngokwezinga elithile, futhi ingakwazi ukumelana nokusebenza kwansuku zonke kwezitimela. Umfutho ophakeme kanye nokulahlekelwa ukungqubuzana kwamasondo. Isizathu sokuthi kungani insimbi engagqwali ingamukeleki yingoba ayihlali isikhathi eside ngokwanele futhi yonakaliswa kalula ngaphansi kokunwetshwa kokushisa nokuncipha. Ngaphansi komoya wansuku zonke, imvula nokuchayeka, insimbi engagqwali ingalimala kalula. Futhi nakuba lolu hlobo lukaloliwe olude noluqinile lubukeka lugqwalile, kunongqimba lokugqwala kuphela, futhi ingaphakathi lisaphelele.
