Ikhwalithi yezinyo lebhakede kanye nezinyo lebhakede lapho sithenga izinyo lebhakede nezinye izingxenye eziwumshini, into evame ukucindezeleka, leyo yindlela yokuthenga nokuthenga lokho, ukuthenga lokho mkhiqizo. kwakho!
Kutholwe izimbobo zomoya eduze kwendawo eshisayo yezinyo lebhakede elisikiwe, futhi kwatholakala nezimbobo zomoya odongeni eduze nendawo engaphakathi. I-stomata ekuxovelweni kokuxova ingahlukaniswa ibe yi-stomata ehlukene, i-stomata ehlaselayo kanye ne-stomata ephindaphindayo, kanye nase-stomata. inqubo yokwakha i-shrinkage cavity kanye ne-porosity of casting, iningi lazo lihambisana nokuhlukaniswa kwegesi. I-stoma izoba nzima.Ngokuhlaziya amazinyo ebhakede, singabona ukuthi ukusakazeka kwesisu akwenzeki, futhi imbobo inkulu, ikakhulukazi eyindilinga futhi iyindilinga yebhola, inganquma ukuthi lesi sisu ngokuyisisekelo singesesisu esihlaselayo.
