So, using magnesia and calcia crucible in VIF respectively, the experiments on deep deoxidation by carbon and the phenomenon of oxygen contamination from crucible materials in the molten steel under some temperature and vacuity and oxygen content of the molten steel were made and it were found that properly low melting temperature and vacuity helped to lighten and even avoid oxygen contamination from crucible material and the refining effect of final oxygen content of 5×10-4% in the molten steel was achieved using calcia crucible with better resistance to thermal shock under higher vacuity.

为此，分别采用MgO炉衬与CaO炉衬，在真空感应炉中对钢液用碳进行深脱氧和炉衬供氧现象实验研究，发现：(1)在适当低的熔炼温度和真空度下，可以减轻甚至避免炉衬热分解向钢液供氧；(2)采用热稳定性优越的CaO炉衬，在较高的真空度下可达到钢液最终全氧含量低于5×10-4%的精炼效果。

Under high temperature and vacuum, calcia crucible has better resistance to thermal chock and better chemical denudation than magnesia crucible.

在高温和真空下，CaO质炉衬的热稳定性和化学稳定性远比MgO质炉衬好。

The results showed that magnesia base catalyst-sorbent was available to denitrification of flue gas by direct catalytic decomposition method the best calcinations time and temperature was 3-4 h and 350-500 ℃,and the denitrification rate was 85%- 95%.

结果表明，利用氧化镁基催化吸附剂可以对烟气进行直接催化分解脱硝，其最佳的焙烧温度和时间分别为350～500℃和3～4h，脱硝率可达85％～95％。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
