本文叙述了由于原子时的精确度大幅度提高,国际上和国内全部测时测纬的经典仪器将要停止观测,取而代之的是人卫激光测月和甚长基线干涉仪等新技术,在天测界的仪器更新换代对于地球物理、地震学界也带来一定的影响。对比之下,由于数字化地震仪的广泛使用,使得地震工作者测定不同频率范围内的谱震级将变得易于进行,预示着在测定震级工作中也将出现某种新的局面,使得当前定震级当中所存在的问题和困难较易得到解决。
This article describes the atomic accuracy as a substantial increase in the international and domestic all measuring time-measuring latitude of the classical instrument will stop the observation, replaced by human-moon laser moon and very long baseline interferometer and other new technologies, The upgrading of instruments in the community also brings some influences on geophysics and seismology. In contrast, due to the extensive use of digital seismometers, the seismic workers’ determination of spectral magnitudes in different frequency ranges will become easier, indicating that there will also be some new situation in the determination of magnitude so that the current magnitude The problems and difficulties that exist among them are easier to be solved.
