查询词典 block off

Oracle coalesces the free space of a data block only when (1) an INSERT or UPDATE statement attempts to use a block that contains enough free space to contain a new row piece, and (2) the free space is fragmented so the row piece cannot be inserted in a contiguous section of the block.

Oracle在满足以下条件时才会将释放的空间合并到可用空间区：（1） INSERT 或 UPDATE 语句选中了一个有足够可用空间容纳新数据的数据块，（2）但是此块中的可用空间不连续，数据无法被写入到数据块中连续的空间里。

The motion scope judgement search method based prognosticating the search beginning point, it utilizes the time relativity and the space relativity of block to prognosticate the search beginning point, and adopts the different search pattern according to the block motion scope, the search efficiency is close to the Three Step Search, which proves the feasibility of researching the new efficient motion estimation algorithm according to the characteristic of block motion to use the different search methods; In the end, this paper evaluates the advantage and disadvantage of the different fast algorithms through the data get from the experiment, it will have some reference value to bringing the new and effective motion estimation fast algorithm in the later research.

基于预测起点的运动幅度判断搜索法，该算法利用块的时间相关性和空间相关性来预测搜索起点，根据块的运动幅度大小分别采用不同步长的搜索策略，搜索效率比较接近三步法，证明了根据块运动的特性以结合运用不同的搜索算法来研究有效的运动估计算法的可行性。最后本文通过实验得来的数据来定量地分析评价各快速算法的优缺点，对今后提出新的更有效的运动估计快速算法具有一定的参考价值。
