为研究长周期地震动反应谱特性，本文首次采用了地震学研究所使用的宽频带数字地震记录作为数据基础。
In this paper, we use the digital broad-band records to study the characteristics of long-period ground motion.
如果这么做，在宽频带上每秒都将需要记录数以亿计的数据点，这实在是需要太多的数据存储和系统分析。
Doing so for such a broad band would require recording hundreds of millions of data points each and every second, which is simply too much data for storage and systematic analysis.
