Based on the summarizing of the exiting algorithms of the texture mapping and antialiasing, this paper goes deeply into the basic theory and processing of texture mapping. The texture compress algorithm which can satisfy the need of the memory and time is given for the stochastic sampling in the inverse texture mapping; the geometry transformation in the texture mapping are discussed and the concepts of the unitary parametrization and the patch parametrization is proposed, some kinds of the unitary parametrization methods of parametric surfaces and the geometry transformation in the patch parametrization are also presented; in order to solve the aliasing in the parametrization of intermediate surface-sphere in two-part texture mapping, an area-preserving transformation is presented also; to improve the quality of the graph the aliasing in the texture mapping is analyzed from the aspect of signal process, and the modified summed-area tables algorithms is proposed; the distortion of the scanline conversion algorithms under perspective transformation is analyzed and the proper interpolation algorithm is presented so the aliasing problem of the polyhedral object after the unitary parametrization is efficiently solved.

We then follow the trend of farmland pattern evolution and take 2001 as the baseline year to forecast the farmland pattern in 2002 through 2010 using linear extrapolation. The result shows that the clustered rather than scattered farmhouse development type would create more integrated farmland pattern through patch integration and form more regular patch shapes that in turn have better effects on farmland utilization.

而在农地利用的变化趋势中，以民国九十年为基准年，采直线之比例关系，推估民国九十一年至民国九十九年建筑总面积，发现若将个别农舍开发改采集村农舍开发方式后，对於块区具有聚集与整合的效果，使农业用地完整性增加，形成较规则的块区形状，对於农业用地利用的确有较佳的影响。

Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.
