集中参数系统是指这样一些系统，其物理特性都集中在一个或者多个集中体上，因此与空间分布无关。
Lumped parameter systems are those for which physical characteristics are assumed to be concentrated in one or more 'lumps' and thus independent of any spatial distribution.
最后对其散射远场声压的空间分布特性进行了数值计算。
Finally, the space distribution characteristic of scattered far-field pressure was calculated and plotted numerically.
该算法由于利用了序列图象运动矢量的空间分布特性—中心偏置分布特性，可以明显地将搜索次数降低到(25 - 55)次。
Based on the image sequence's spatial characteristics of center-biased motion vectors, this method can significantly reduces the search times to (25-55).
