The invention relates to a method for adopting a compound reducing agent to reduce and decompose phosphogypsum; the method comprises the following steps of: using high-sulphur coal and coal gangue to prepare the compound reducing agent; utilizing tail gas to dry the phosphogypsum and the compound reducing agent which are ground and mixed evenly and then transferred into a reducing and decomposing furnace; carrying out reduction and decomposition till the reaction is completed.

要約 本发明涉及一种采用复合还原剂还原分解磷石膏的方法，该方法将高硫煤和煤矸石配成复合还原剂，再将磷石膏、复合还原剂利用尾气烘干、磨细后混匀送入还原分解炉，进行还原分解，直至反应完全。

At the temperature of liquid nitrogen the N 2 adsorption process and adsorptive volume of coal samples are measured under the gas saturated vapour pressure.Using BET and BJH theoretical models the pore volume and area of coal are calculated.

在液氮温度下，通过测试煤样在气体饱和蒸气压力范围内对N2 的吸附过程及吸附量，用BET和BJH理论模型计算出煤的孔体积和孔表面积。

These vacant jobs in oil, coal, and gas are likely to attrite; coal mining already becoming defunct in the early 21 st century.

这些空置的工作在石油，煤和天然气很可能就流失了；煤矿已经成为倒闭在21世纪初。

Had appeared to replace firewood bavin with coal on human history, replace coal with oil, natural gas, with but the process that second birth the sources of energy replaces mineral the sources of energy.

在人类历史上已经出现过用煤炭替代薪柴，用石油、天然气替代煤炭，用可再生能源替代矿物能源的过程。

Vitrinite and desmocollinite have a relatively low potential of hydrocarbon generation. The stable carbon isotope composition of their pyrolysis oils is heavier than that of sporinite, cutinite and oils derived from coal-bearing strata. It seems that they cannot be major macerals to generate oil, even if they occupy a majority of proportion in the organic matter of coal and coaly shale, and that they can be good gas-prone macerals at the stage of high-maturity to over-maturity.

镜质体和基质镜质体的生油潜力相对较低，其生成的液态烃类的碳同位素组成比一般煤系原油重得多，而且这些组分本身对液态烃具有较强的吸附力，尽管其在煤系有机质中所占的比例很大，仍然难以成为生成液态石油的主要显微组分，只能在高成熟演化阶段成为良好的生气显微组分。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
