The result shows that the main factors,which affect the technical quality of the cathode assembly preparation,are surface oxidization of emissive layer,impurity pollution,doped concentration nonuniform,less variation of doped concentration gradient,the sticking stress of GaAs and glass,and the main factors,which affect the cathode activation,are the degree of vacuum for activation at lower than 8x10-8Pa,the partial pressure of H2O,CO,CO2 and C in the vacuum residial gas at higher than 10-8 Pa and the improper caesium and oxygen refining.

结果表明，影响台外工艺质量的主要因素是外延材料缺陷多、发射层表面氧化、杂质污染、掺杂浓度不均匀、掺杂浓度陡度变化小及GaAs与玻璃粘接产生的应力大；影响台内工艺质量的主要因素为阴极激活真空度低于8×10-8Pa。真空残气H2O.CO.CO2及C分压大于10-8Pa。阴极激活铯和氧源提纯不彻底。

The article educes a relation about charcoal percent conversion and running temperature, gas caloricity, gasification efficiency, system efficiency by three programmes's calculation. So charcoal percent conversion has important influence on system's operation. And It is confirmed that air partial gasificat ion combined cycle generation system is a high efficiency, low pollution, techno logy simpleness, low investment, short periodicity generation system by comparis on with else combined cycle generation systems of different gasification mode.

文章通过对三种方案的计算，得出了碳的转化率与运行温度、煤气热值、气化效率、系统效率之间的关系，证实了碳的转化率对系统运行有重要的影响，同时和其他气化方式下联合循环发电系统进行比较分析，证实煤的空气部分气化联合循环系统是一高效低污染、技术简单、投资小、见效快的发电系统。
