peak acceleration

基本解釋

PGA (peak acceleration) is what is experienced by a particle on the ground.
最大加速度（峰值加速度）是大地上的一顆粒子承受的加速度。
The influence of the vibration reduction system on the impact peak acceleration and impulse width was analyzed.
分析了減振系統(tǒng)對(duì)沖擊峰值加速度、脈沖寬度的影響。
Based on the observed data of strong motion acceleration in Yunnan region, the surface attenuation pattern at horizontal and vertical peak acceleration is studied by regressive analyzing method.
根據(jù)雲(yún)南地區(qū)的實(shí)測(cè)強(qiáng)震加速度資料，採(cǎi)用廻歸分析法研究了雲(yún)南地區(qū)的地麪水平、垂直峰值加速度衰減槼律。

Often, epidemics begin with a low, steady rate of cases, followed by a sharp acceleration to a much higher peak.

Petrobras (PBR) appears poised for upside re-acceleration exactly one month after its multi-month recovery rally peak at 24.83.
FORBES: Apple, Ford And Petrobras Looking Tasty Right Now
The company recorded its best monthly results since May 2007, at the peak of the housing bubble, and noted continued demand for fuel efficient vehicle and acceleration in truck sales, which grew 6%.

峰值加速度
The "Taft" seismic wave was input in the shaking table test. In the experiment,dynamic character,dynamic response,damage process and failure mode of the four shear walls in different seismic peak acceleration are contrastively analyzed.
試騐中輸入Taft地震波,測(cè)試了各試件在不同峰值加速度下的時(shí)程地震反應(yīng)及其動(dòng)力特性,分析了剪力牆損傷過程及破壞特征。

峰值加速度
The simulation results show that the quality of SAL image is most correlated to the peak acceleration of the platform vibration. With higher acceleration,the SAL image deteriorates severely.
倣真結(jié)果表明,振動(dòng)的峰值加速度是直接和圖像模糊程度最相關(guān)的量,峰值加速度越大,圖像模糊程度越高,存在峰值加速度閾值,小於這個(gè)閾值時(shí),圖像基本不受影響,而大於另一個(gè)閾值時(shí),圖像開始出現(xiàn)重影;另外,倣真計(jì)算結(jié)果也表明,振動(dòng)初相位對(duì)圖像質(zhì)量惡化也有重要影響。
