Example Sentences:

	1.	In addition , the seismic magnitude up to 9 degree in this valley is favourable for the formation of debris flow 另外该区9度的地震烈度，为泥石流的形成与发育提供了有利条件。
	2.	In the first step . 2861 surface wave recordings with seismic magnitude over 5 . 0 are selected under the criteria of good - wave and " intact recording " , calculating the big - circle paths , and then about 284 two - station pairs of which two stations are along the same big - circle are chosen , among them there are about 260 pairs with difference of forward azimuth angle less than 5 ? . after further optimizing , 223 pairs which perfectly cover the china area are used in the final calculation 本文首先从所收集的震级在5级以上2861条面波记录中挑选波形好、记录完整的资料进行预处理，计算其大园路径，从中挑选出位于同一地震大园路径上的双台地震记录约284对，然后计算出前向方位角差，其差在5范围以内的双台地震记录约260余对，量后对这些记录进一步优化，选出223对对中国大陆地区覆盖比较好的面波记录。
	3.	In addition , effects of several factors such as local site conditions , focal mechanism , epicentral distance and seismic magnitude on these parameters are discussed , and several significative results and conclusions are obtained . in all records there are about 1 / 3 vertical ground motion ’ s peak acceleration bigger than 2 / 3 of the corresponding horizontal one , so the action of vertical ground motion should not to be underestimated . vertical design response spectrum equals that the horizontal design response spectra times 65 % is probably unsafe when period is short , and suggest adopting different coefficients when at different periods 本文基于对大量欧洲强震记录的研究,分析了地震动竖向与水平向分量在峰值加速度、反应谱值、频谱周期等参数方面的差异,以及这些参数与场地、震源机制、震级和震中距的关系,得到了以下有意义的结果和结论:在本文分析的地震记录中大约1 / 3的记录加速度峰值比大于2 / 3 ,竖向地震动分量的作用不可低估;在短周期,竖向地震动影响系数的最大值仅取为水平向地震动影响系数最大值的65 %是偏于不安全的,可以考虑按周期分段采用不同的折减系数;我国现行抗震规范中设计反应谱特征周期的取值偏低,可能是偏于不安全的;竖向与水平向地震动分量卓越周期的比值在0 . 7 - 0 . 9之间,竖向设计反应谱的特征周期应有单独规定。
