For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

根据我们计算和实验的结果，我们得知在没有阻塞的尿道流场内，摩擦损失是影响压力损失最主要的因素；而在轻微阻塞的尿道流场内，磨差损失及阻塞段几何外型改变，面积改变的能量损失都影响很大；而在较为严重的阻塞情况下，阻塞段的外型，最小截面积等影响能量损失甚为巨大，另外我们根据计算的结果发展出一个无因次参数图，我们选用了Reynolds number和来做参数，结果发现这样不仅可以把阻塞和未阻塞的病例分清，甚至能判断逼尿肌无力等症状。

The results calculated by the Elovich rate equation showed that K release rates from 1 mol.L-1 HNO3 extraction ＞those from 2 mol.L-1 HNO3 extraction ＞those from H-resin extraction. Elovich equations combining with the data of H-resin and 2 mol.L-1 HNO3 successive extraction could well described the release characteristics of soil K. The correlation coefficients of the equations reached most significant levels (r＝0.956**—0.999**), and standard errors of specific K release capacities between the vaules calculated by the equations and those measured by both successive extractions were smaller(s=1.61 and 3.52). The specific release rates of soil K calculated by the Elovich rate equations were significantly correlated with the indices of soil K availability (the amounts of easily available K, nonexchangeable K, total available K in soils and K absorbed by ryegrass).

摘要从理论和数值试验两个方面证明地形的非均匀性对网格区地面长波辐射通量的计算有重要影响，海拔高度场的区域平均值及其变差系数是影响网格区地面长波辐射通量的主要因素，仅仅用地表均匀假定下的区域平均参量（如平均海拔高度和平均温度）所计算的网格区地表有效辐射通量值与其真实值之间存在着一定的误差。

在本论文中，我们提出了三个改良式的演算法，第一个为Apriori演算法来动态探勘，其二为使用布林演算法为基础进行动态探勘，最后为以布林运算为基础之FP-tree的动态探勘，可以提升异动资料库的探勘效率，因为在过去的资料探勘技术中，在探勘关联规则的过程中，若有新增或删除交易资料时，则必须重新计算一次，将造成前次探勘计算的重复及资源的浪费，所以本论文的改良式演算法当有新增资料时将不用每次都要重新扫描整个资料库，绝大部分只需要扫描新增的交易资料，以提升探勘效率。
