The seismic response of the structure with long period will be over estimated, if the standard spectrum or the design spectrum given by seismic risk analysis is applied.

而长周期结构采用规范设计反应谱或由地震危险性分析给出的场地设计反应谱计算所得的地震反应结果偏大。

The MPG equivalency rating was developed by the EPA as a way to provide a standard so consumers can compare vehicles across the spectrum and make an educated purchase.

ENGADGET: Nissan Leaf blessed with 99MPG 'equivalent' sticker, roundtable arguments ensue

But the new 4G mobile standard, called LTE, gets the biggest bang for the buck in wider spectrum bands.

FORBES: Damming the Digital River

The governments agreed on a common standard for digital communications, and to enable it they freed a common bloc of spectrum across the continent.
