coalescing

基本解释

The effectiveness of caching obviously depends on the costs of splitting, coalescing, and searching relative to the work needed to track cached chunks.
很明显高速缓冲的有效性依赖于分割合并和查找的开销相对与用于跟踪被高速缓冲的块的开销。
Thus, the general categorization of this algorithm is best-first with coalescing: Freed chunks are coalesced with neighboring ones, and held in bins that are searched in size order.
因此，这个算法一般被归类为带合并的最佳适合算法：释放的邻近的块被合并，并被保存在按大小搜索的箱子里。
The fear, rather, is that with all the state institutions now in conservative hands the unelected centres of power are coalescing behind a single hard line and taking over all the top jobs.
而真正让人担心的是，如今所有国家机构都掌握在保守派的手中，非选举的各个权力中心将遵循一条强硬路线联合在一起并占有国家所有的高层职位。
