For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.

为了减小小波变换山区格网DEM数据压缩中边界失真区域，将山区格网DEM高程值视为广义坐标下的离散随机序列，把二维离散小波变换中的边界问题转换为一维离散小波变换中的边界问题，不仅大大减少了小波变换边界失真区域，提高了重构DEM数据边界点的精度，而且减少了边界补零个数，提高了压缩比；通过对山区格网DEM数据小波变换低频区和高频区变换系数分布特点的分析，采取了霍夫曼—游程混合熵编码方案，设计了高效、低失真的"自适应硬阈值"量化器，即对低频区变换系数不进行量化，直接进行霍夫曼编码；对高频区变换系数则先用"自适应硬阈值"方法量化处理，再进行游程编码。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.

Through theoretical derivation, the author proved that the Landweber method is the transmogrification of the iteration solution of the generalized inverse, so the phenomenon that the reconstructed images of Landweber through many iterative processes is close to those reconstructed by generalized inverse method is explained, then a new reconstruction algorithm, namely pre-iteration method is presented, which divides the process of reconstruction into two steps, namely off-line pre-iteration and on-line one-step reconstruction.

通过理论推导，作者证明了Landweber法实际上可归于广义逆矩阵迭代求解的变形，从而解释了Landweber法多次迭代后，趋于广义逆解的现象。

Watterson is, is not in any way necessary--the utterance of his name is enough; a name which is like one of these electric announcements on the Madison Square tower: the mention of it touches the button in our memory and his history flashes up out of the dark and stands brilliantly revealed and familiar: distinguished soldier, journalist, orator, lecturer, statesman, political leader, rebel, reconstructed rebel: always honest, always honorable, always loyal to his convictions, right or wrong, and not afraid to speak them out; and first, last, and all the time--whether rebel or reconstructed, whether on the wrong side or on the right--a patriot in his heart.

如果要告诉美国观众谁是中校，是沃特森，没有任何方式是必需充分表达他的名字；在麦迪逊广场塔像这些令人震惊的公告是一个名字；提到它涉及的一点点在我们的记忆中和他的历史上闪烁出黑暗并随时出色的显露和熟悉：尊敬的士兵，新闻记者，演说家，讲师，政治家，政治领袖，南方叛军，重组叛军：永远诚实，永远光荣，永远忠于自己的信念，正确或错误的，不怕他们说出去；第一，最后，所有的时间-无论是反叛或重组，无论是站在错误或正确的一方----一个爱国者的心。

The marine carbonate near the unconformity was mainly reconstructed by strong atmogenic freshwater during the Indo-China and Yanshan Movement, being better reservoir. The reconstructed records behave as following: the ratio for 87Sr/86Sr in the different carbonate minerals or structural components is higher than carbonate matrix, while the δ13C and δ18O value in mass of samples in the different carbonate minerals or structural components are lower than carbonate matrix.
