摘要
本文描述了为国内VLBI网络而建立的新型、可搬运氢激射器的环境性能测试,给出了磁场、压力、热性能的测试结果。测试表明,在0～3.33×10~3Pa压力变化范围内无明显压力效应,而磁场与热灵敏度分别为1.1×10^(-12)/G与3×10^(-14)/℃(时间常数为32小时或更长),后者还包含了快作用与慢作用两个过程。
Evironmental performance measurements of the new transportable hydrogen maser constructed for the VLBI network in China is described. Results from magnetic field, baromentric pressure and thermal tests are given, The measured sensitivity to both magnetic and thermal fluctuations are 1.1E12/G and 3E-14/℃ (time constant is 32 hours or more) respectively, The later one includes fast-acting and slow-acting processes.
