新建国家数字地震台网所使用的CTS1甚宽频带地震计是一种具有甚宽频带、大动态范围、高灵敏度负反馈地震计。

The CTS-1 very broadband seismometer employed in New State Digital Seismic Network is a seismometer of very broadband , large scale dynamic and high sensitive feedback .

国家数字地震台网中心是中国数字地震观测系统的资料收集、处理、管理、保存和提供各种服务的中心。

The National Digital Seismograph Network Center is a center for data collection , processing , management and preserving of the China digital seismologic observation system . It can provide various services .

以此为基础，讨论国家数字地震台网目前大震速报的模式，分析了在数字化代替模拟以后使用速度震级的可行性，以及量取20秒周期面波震级的必要性。

On the basis of this , the feasibility that the velocity magnitude might be adopted after digitalization replaces analogy , and the necessity that the surface-wave magnitude is determined at the 20-second period are discussed .
