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。

Based on the depositional characteristics and stratigraphic feature of Inland Basins, Western China, and taken examples from Zhongger and Tsaidam basin, in this paper, the author probes systematically into syntheic methods applied to analysing subsurface sedimentary facies, predicting and mapping the source, reservoir and cap rock of oil/gas, and studing the stratigraphic model of sedimentary facies as well as the seismic models with all of information which come from outcrop section, drilling profiler, well log, seismic prospecting and examples data.

近十年来，作为有现代化测井技术、反射法地震勘探技术和计算机数据处理方法等参与的盆地油气勘探已为这一工作提供了新的信息并增加了新的分析内容，以地表露头剖面和钻井岩蕊观察为基础、进而在区域上作出推断的纯定性传统沉积相分析方法已经不适应当今油气勘探的要求，因此，如何充分利用地质、测井、地震及其他方法提供的大量信息，用综合化、程序化乃至定量化的方法进行盆地沉积相分析和其他研究近年来受到石油地质学家们的普遍关注。

Reagan was born in Tampico, Illinois, in 1911. Before entering the politics, he had been a lifeguard, a sports radio announcer, a columnist, and a movie and television actor. Reagan was elected the Governor of California in 1966 and was reelected in the consecutive term where he stayed in office until 1974. In 1981, he became the 40th President of the US. Followed the end of the detente in 1979, Reagan, fearing the balance of power would be distorted, introduced the Strategic Defense Initiative sometimes dubbed as the "Star Wars"(「星战计划」 of 1983, which proposed to deploy a space-based defense system to make the US invulnerable to nuclear weapon missile attack. This was aimed to add value to the US military strength, hence forcing the USSR into unsustainable military spending to maintain parity, and upsetting her economy.

列根在1911年於美国伊利诺州坦皮科出生，年轻时曾担任过运动广播员、救生员、报社专栏作家、电影演员、电视节目演员。1966年至1974年，连任两届加利福尼亚州州长。1981年，宣誓就任第40任美国总统。1979年，冷战缓和时期结束，美国为免与苏联「核平衡」的形势被打破，列根於1983年提出「星战计划」，建立一个以外太空为基础的飞弹防御网，以维持其战略优势及拖垮苏联的经济。
