In the discussion of compensable usage of underground space , the paper put great emphasis on the technique economy analysis in the different stage of underground engineer , and the establishment of a price model of underground business space , moreover , some suggestions for the future government policy about compensable usage of underground space are made 对于城市地下空间有偿使用的分析，本文重点分析了一般地下工程各阶段的经济技术分析与评价。并在此基础上，探讨了商业用途的地下空间使用权地价评估模型的建立，并对商业用途城市地下空间有偿使用政策作出建议。
A novel motion estimation algorithm which is based on compensability analysis of the input video signal is proposed . the motion estimation operation is performed only on the compensable blocks in the image frame . the time of estimation computation and the bits for coding the motion vectors are all reduced significantly than those of conventional algorithms 本文介绍了一种新颖的运动矢量估计算法，我们首先对待编码的图像进行可补偿性分析，然后运动矢量搜索只对可补偿块操作，因此无论是搜索次数还是用于对运动矢量编码的比特数均明显少于传统算法
