Diagnostic neutral beam (DNB), combined with spectral diagnostics, is employedto measure the ion temperature in HT-7. The factors affecting the extracted beam are studied inthe experiment for the high performance diagnostic neutral beam. A 6.5 A extracted hydrogencurrent at 43 keV of 100 ms was obtained after optimization. The extracted beam has a protonratio as high as 40%, and can penetrate into the core plasma after neutralization to measure theion temperature effectively.

本文考察了俄罗斯西化运动的历史，探讨了几个世纪以来俄罗斯西化运动的背景、模式及其在文化上的后果。作者认为，近代以来，俄罗斯处于一种文明的边缘状态，即相对于西欧始终是落后和不文明的，但相对于北美以外的亚非拉其他地区来说，它既接近文明的中心深受其薰染，又相对发达。这种特殊的国际环境是俄罗斯长期以来不断西化运动的主要背景。俄罗斯的百化运动是在缺乏社会内部推动力，而在外部压力推动下进行的。它以建立西方化的市场经济体制为目的，但既未以市场化的方式进行，最终也未能达到建立市场经济的目的。这一矛盾长期发展下去便在民族
