宽频带记录 meaning in Chinese
wide-band record
Examples
- From the velocity - type records and the acceleration - type records in one station the same ground motions can be recovered , and the calculated response spectra are the same in a specific period range . this indirectly proves the reliability of the two types of records
速度型和加速度型数字宽频带记录可以恢复出相同的地震动，在一定的川朋范田内得到相同的反应谱，间接证明了这两种地恁记录的可靠性。 - We find that the noise level of the record is very low . even in weak ground motion condition the digital broad - band record has high signal - to - noise ratio when the period is as long as 20 sec . the signal - to - noise ratio of the velocity - type records is lower than that of the acceleration - type records
木义发现，数宇宽频带记录的啪卢水平很低，在川朔k达205时，即仗在弱地震动的惰况下，还具有较高的信啪比，并且浊度型记录的信噪比禾厂加让度型门录的信噪比。 - 754 horizontal - component digital broad - band records in western north america are processed . the acceleration response spectra are calculated and used as part of the database . the response spectrum values are estimated by the earthquake magnitude definition and are used as another part of the database
将美国西部地区作为参考地区，对美国南加州地区的数字宽频带记录进行了搜集与处理后作为观测资料，共754条水平向记录，与利用震级定义所估计的反应谱值一起，用统计回归的方法建立美国西部长周期加速度反应谱衰减关系。 - The reliability of the observation data in long period range is particularly inspected . this is done " by verifying the instrument response characteristic , examining the signal - to - noise ratio , comparing the recovered ground motions and response spectra from the velocity type and acceleration type digital broad - band records
对于速度型和加速度型的数字宽频带记录，从仪器特性、恢复的地面运动对比、信噪比研究、反应谱对比等方面研究这类记录在长周期段的可靠性。
