摘要：

The NIM4 caesium fountain clock has been operating stably and sub-continually since August 2003. We present our improvements on NIM4 in 2005-06 and the most recent evaluation for its frequency shifts with an uncertainty of 5 x 10(-15). A 203-day comparison between NIM4 and GPS time shows in agreernent of 2 x 10(-14). Finally the construction of the NIM5 transportable caesium fountain clock is briefly reported.
