| Ibiranga ： | Ifite imbaraga nyinshi zubushyuhe (δb≥440MPa) hamwe na okiside irwanya ubushyuhe bwinshi, kandi ifite imbaraga zo kurwanya ruswa ya hydrogène. Coefficient yo kwagura ubushyuhe ni ntoya, ubushyuhe bwumuriro buri hejuru, imikorere yimikorere ni nziza, ubushyuhe ni dogere selisiyusi 450-620, gukomera kwicyuma biragaragara, kandi gusudira ni bibi. Ikoreshwa cyane mugukora turbine na parike, kandi ikoreshwa cyane mumiyoboro ihinduranya ubushyuhe hamwe nubushyuhe bwo hejuru hamwe nubwato bwumuvuduko mwinshi. | Ifite imbaraga zo kurwanya okiside hafi ya dogere selisiyusi 650, imbaraga zumuriro ziri munsi ya 600, kwinjiza neza no gutwarwa nubushyuhe, kandi ikoreshwa cyane muri turbine. Nyamara, ubu bwoko bwibyuma bufite imyumvire nini yo gukomera kandi bufite imikorere mibi yo gusudira. Ifite ubushyuhe bwiza bwo hejuru, ubukana bwa microstructure, kurwanya ruswa, no gukomera. Ikoreshwa cyane muri peteroli, guhinduranya amakara, ingufu za kirimbuzi, guhagarika turbine, amashyanyarazi hamwe nibindi bikorwa bibi, ibidukikije byangiza ibidukikije. | ||
| Gusaba ： | Ibikomoka kuri peteroli, ibikomoka kuri peteroli, ibyuka byumuvuduko mwinshi, hamwe nindi miyoboro idasanzwe idasanzwe idafite imiyoboro irimo imiyoboro itagira kashe, imiyoboro ya geologiya idafite ibyuma, hamwe na peteroli idafite peteroli. Imiyoboro hamwe no kwibagirwa birashobora gukoreshwa mumitsi. Imiyoboro hamwe nimitwe ifite ubushyuhe bwurukuta ≤510 ℃; Gushyushya umuyoboro wubushyuhe hamwe nubushyuhe bwurukuta ≤540 ℃. | Ubushyuhe bwo hejuru bwa sulfure, ubushyuhe bwo hejuru hydrogène na hydrogen sulfide yangirika, aside aside yangirika. Umuyoboro ushyushye ufite ubushyuhe bwa 630 ℃ -650 ℃. Imiyoboro hamwe no kwibagirwa birashobora gukoreshwa mumitsi. Ubushyuhe bwo hejuru bwa sulfure, ubushyuhe bwo hejuru hydrogène na hydrogen sulfide yangirika, aside aside yangirika. Umuyoboro ushyushye ufite ubushyuhe bwa 630 ℃ -650 ℃. | ||
