Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer. The result showed that the growth of subaerial parts of plant community isn't obviously isochronous with the seed bank. So the inherent potential of soil seed bank has important influence on the regeneration of forest and the dynamic succession of plant community.

另外，种子库中优势成分与取样地点地面植被相应层次的优势种存在较大差异，说明植物群落地上部分的发育与其它地下部分的土壤种子库的发育具有明显的不同步性，这一结果表明土壤种子库的内在潜力对森林更新及植物群落演替动态产生了重要影响。

Experimental results have shown that the proposed algorithm can not only adaptively select the suitable subsample ratio to various video sequences but also maintain ΔPSNRY of 0.36 dB at most to save about 69.6% power consumption of motion estimation in a fixed bit rate control on average.

我们提出的这个演算法已经成功的实现在H.264/MPEG-4 AVC的软体模型JM9.2中，实验结果显示这个演算法不只可以动态的依照不同的影像内容来选择适合的取样率，而且可以维持最多0.36 dB的画质衰退，在固定的传输频率下，平均可以节省69.9％的能量损失。

In this theory, we firstly introduce the basic theory of discrete wavelet transform and lifting scheme. Secondly, we adopt a fully pipelining VLSI architecture for lifting-based DWT. Hence, we can operate on higher working frequency. Besides, we merge a QCB-based DWT method to achieve the higher parallelism for JPEG 2000 encoding system. By changing the output timing of the DWT process, the internal tile memory size can be reduced by a factor of 4. Moreover, the architecture can efficiently perform shape-adaptive DWT and solve boundary extension and subsampling problems. Finally, according to the comparison results with other architectures, the efficiency of proposed architecture is proven.

在这篇论文中，首先我们介绍离散小波转换和提升式架构的基本理论，接下来我们改良提升式架构采用全管线化的硬体架构，因此我们可以操作在较高的工作频率，并且我们合并了以四个编码方块为基础的方式来使得JPEG 2000编码系统具有更高的平行度，藉著改变离散小波转换的输出时序，内部的记体体需求可以减少为原本的四分之一，接著此架构也可以有效地支援可适应形状的离散小波转换，同时解决了边界延伸和子取样的问题，最后根据与其他架构比较的结果，来说明所提出之离散小波转换架构的贡献。
