1·Did equilibration take place before or after setting of chromite and silicates?
究竟平衡作用发生在铬铁矿和硅酸盐下沉之前，还是在其后？
2·Investigates experimentally the fluidization and reduction processes and coal - adding conditions of powdered chromite ores in a fluidized bed.
探讨了粉状铬铁矿在流化床内的流化性质、还原过程和加煤条件。
3·Chromite is main raw material for smelting ferrochromium.
铬铁矿是生产铬铁合金的重要原料。
4·Microwave heating method was used to reduce coal-containing chromite fines, scarce chromite resources can be fully used, technical process of ferrochrome smelting is simplified.
利用微波加热的方法来还原含煤铬铁矿粉，稀缺的铬铁矿资源可以得到充分利用。
5·Three chromites were studied by using Mssbauer effect in this paper. The Mssbauer spectra of chromite L-1 at 150k and 298k and of chromites L-2 and L-3 at 298k were measured.
本文使用穆斯堡尔效应对三个铬铁矿进行了研究，测量了铬铁矿l - 1在150k和298k温度下的穆斯堡尔谱和铬铁矿l - 2和l - 3在298k温度下的谱。
