When gas superficial velocity was about equal to liquid superficial velocity, the probability density function of liquid holdup had a twin-peaked, when liquid superficial velocity was constant, one of the peaks would fade out and disappear with the in crease of gas superficial velocity. Through using the characteristics, the relative size of gas and liquid superficial velocity can be set initially.

在段塞流动中，当气相折算速度和液相折算速度相差不大时，持液率概率密度函数呈双峰分布；当液相折算速度不变时，随着气相折算速度的增大，持液率概率密度函数第2峰值逐渐减小，直至消失而变为单峰分布；利用这一特征可初步确定段塞流动中气、液相流量相对大小。

The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.

结果表明，废塑料与煤混合物在煤的塑性温度区间内存在明显的相互作用，使最大热解失重峰迁移，热解速率变大，且随着废塑料配比的增加呈现规律性的变化；煤热解产物固体焦炭为主，而废塑料的热解产物以焦油为主，废塑料的添加使得总体焦炭和水产率下降，焦炉煤气和焦油的产率增加，即共焦化呈现出明显的&增油减水&效应；随着塑料添加量的增加，焦炭热强度呈现劣化趋势；废塑料代替瘦煤配煤炼焦可使其比例提高到3%而不影响焦炭的质量；纯煤焦化所得焦油以芳香烃类和烷烃类为主，而废塑料热解焦油以烷烃和烯烃为主；废塑料配煤炼焦，可使得的焦油呈现&环构化&和&轻质化&趋势；废塑料的添加可使煤气中的可燃组分(CO、H2、CH4)的含量均有不同程度的增加；废塑料配煤炼焦可以优化焦炉煤气的组成，增加煤气中的可燃组分，提高焦炉煤气的热值。

The study shows:(1) the generation of sulphur-bearing gas is controlled by the formation water;(2) the present distribution of hydrogen sulphide is the result of the segregation of water and gas, and it is also influenced by the heterogeneity of reservoirs;(3) the limited distribution of formation water is an important mechanism for forming gas fields of low sulphur content in China.

该问题的研究说明：①靖边气田含硫天然气生成过程始终受地层水控制；②现今硫化氢分布是气水分离结果，并受储层非均质限制；③揭示地层水体分布的局限性可能是形成我国低含硫气田的一个重要机制。

The hot gas duct of China 500 MW Pilot High-Temperature Gas-cooled Reactor connects the reactor pressure vessel and the steam generator. The hot gas duct is the main passage of the helium from the reactor core to the steam generator.
