利用4 . 2k低温面对气体的物理吸附机制实现高气载下瞬时大抽速的液氦低温冷凝泵，具有工作压强范围宽、能获得清洁真空环境的特点。 - Distance between target and substrate get longer also increase the transmission of aln films . as the temperature of substrate get higher , the transmission of ultrathin aluminum films decrease slightly . nitrogen gas concentration and sputtering time barely take effect on the transmission of aln films
发现,随着工作压强的升高、靶距的增加,薄膜的透光率上升;基片温度的升高在非晶衬底上会导致样品透光率的下降;而氮气浓度和溅射时间对薄膜的透光率影响不大。 - The main results are : supersonic region and subsonic region can co - exist in flow path simultaneously , subsonic flow is insignificance for engine performance ; total pressure of primary rocket should be decreased when mach number is increased . in the experimental aspect , some components of ejectorjet experimental system were improved , ejectorjet experiments using alcohol as secondary fuel were conducted
由数值计算获得的结论为：引射火箭内的一般流态为超音速区与亚音速区共存，亚音速区不具备做功能力；飞行马赫数增大，引射火箭内更易于产生壅塞；为了获得最佳的性能，随着飞行马赫数的提高，应当降低一次火箭的工作压强。 - During the inspection by afm and sem , we found that the surfaces morphology of samples was even and smooth , the surface roughness was small . the films were composed of some excellent columnar crystallites . the xps results were found that zn existed only in the oxidized state and the concentration of al was less and the presence of loosely bound oxygen on the surface of azo thin films was reduced after ar + etching
由以上对azo薄膜的组织结构和光电性质的研究,我们得到了用直流反应磁控溅射法制备azo薄膜的最佳工艺条件为:氧氩比0 . 3 / 27 ,衬底温度200 ,工作压强5pa ,靶基距7 . 5cm ,功率58w ,退火温度400 。 - Liquid helium cryocondensation pump has great advantages in large pumping speed , working pressure range and high ultimate pressure , etc . it ' s more excellent than any other vacuum pump . it can meet the vacuum requirement of nbi and can improve the transportation efficiency . the development of neutral beam injection ( nbi ) system in the world , the structure of nbi system used on the ht - 7 device of asipp was introduced in the thesis
