目前常规台站地震观测用钟的状况是:一方面新产品不断涌现、待销;另一方面却是台站用钟告急,急待更新换代。一些省局台站管理部门,花了不少钱,选购了一些新产品,试图解决这一问题。但由于产品性能、质量上的问题,台站用钟就成为一个日益突出、难以解决的老大难问题了。但对地震观测来说,时钟又恰恰是唯一直接涉及观测内在质量的至关重 At present, the status of conventional stations for observing the earthquakes is: on the one hand new products continue to emerge and be sold off; on the other hand, they are used for emergency alarms and are in urgent need of upgrading. Some provincial bureau station management departments, spend a lot of money, bought some new products, trying to solve this problem. However, due to product performance, quality problems, the clock with the station has become an increasingly prominent and difficult to solve the crux of the problem. But for seismic observations, the clock is precisely the only one that is directly related to the intrinsic quality of the observations
