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。

When the two valves are closed, manifold vacuum is applied in opposite senses, thereby canceling the effect of variation in manifold vacuum on opening of the purge flow regulator.

当两阀门关闭时，进气歧管的真空以两个相反方向作用，因此抵消了进气歧管内的真空变化对清洗气流控制装置开度的影响。

The vacuum system uses a compact vacuum pump group and compound gauges with wide measuring range and good hermetization.

真空系统采用复合真空计及真空机组，测量范围宽、设备紧凑、密封性能好。

After the product of the disproportionation under vacuum was treated through washing and vacuum filtering, DPO with content over 98% could be obtained.

减压歧化反应的产品再经过洗涤、抽滤等处理，可以得到含量为98%以上的DPO样品。

We try to synthesize the Co doped TiO2 dilute magnetic semiconductor structure via thermal treatments under vacuum environment, and study its magnetic property. The results reveal that during thermal treatments in a vacuum environment, the Co grains may form the oxide phase structure, and lose their magnetic properties.

研究结果发现在真空高温退火过程中，虽然钴粒子会均匀扩散至非晶的二氧化钛薄膜，其铁磁性的行为却因此消失，由实验结果推断在高温回火过程中，钴可能形成反铁磁的氧化物的结构。
