On the basis of OCM, segmentation based on curvature radium is presented in the paper, in which curvature radium is calculated using parametric-surface fitting, and detecting edge points is realized from orthogonal direction, which ensure the integrality of edge points. Since the data is organized by cross-line in OCM, a new arithmetic, Double-direction Angle Difference arithmetic, is brought forward, which can pick up edge points more quickly.

物体的表面一般由多个曲面相交组成，要建立完整的几何模型，需要对测量数据进行区域分割——区分不同曲面的数据，现有的区域分割大多是对单视图的图像式测量数据进行的，但完整的CAD模型需要联合多个视图产生，本文在上面提出的三维正交模型的基础上，提出了三种区域分割方法：第一种方法是基于曲率半径的数据分区方法，通过二次参数曲面拟合计算局部曲率半径，从正交的多个方向进行检测，保证了边点提取的完整性。

Fruit trees and flowers, birds and animals, shimmering tiles, and the gleam and murmur of running water—these are the vibrant and delicate substances from which, like a beautiful carpet, the Islamic garden is woven.Indeed, Islamic carpet design and garden layout go hand in hand.Garden carpets depict in a stylized manner the chahar bagh, or fourfold garden with its intersecting axial watercourses surmounted by a central fountain.In addition, they depict symbolically the vegetation planted in actual gardens:the shade-giving plane tree, identified with the Tuba tree in the Quran; the cypress representing death and eternity; and fruit trees standing for life and fertility.The central cartouche can interpreted as a platform, which in real gardens was often surmounted by a pavilion.These form the basic and timeless design formula of the Islamic garden—one or more quadripartite sections defined by narrow water courses—which has its roots in ancient Persia where the archaeological remains of Achaemenid palaces trace the outlines of pavilions overlooking carved stone channels.

As this great truth opens up to us, it will help us to understand how in our life, and in our fellowship with Christ, it is impossible for us to share His life until we have first in very deed surrendered ourselves every day to die to sin and the world, and so to abide in the unbroken fellowship with our crucified Lord.

基督死在十字架上表现了最高的圣洁，使我们瞭解他在天上的荣耀，因此圣灵可以在我们里面运行，使我们与基督的十字架相交，我们需要深深的进入这真理，因为除非父神的爱子亲自尝了死味，否则无法回到天堂的荣耀里去，这个至大的真理使我们明白我们的生命，除非我们每天全然顺服，向罪和世界死，并与为我们钉死的主有所交通，否则我们无法分享他的生命。

The main objective of this dissertation was to develop methodologies with capability of engineering application for simulating flow in fractured rock using discontinuum models. The study work includes three parts. In the first part, numerical methodology of three-dimensional discrete fracture network model casing on hybrid BEM-channel was presented, and the technique for improve the model's computing efficiency was also studied.

The results indicate that its dynamic stress-strain curve is hyperbolic type. The dynamic strain of LCES decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency when it is subjected to the same dynamic stress. At the same dynamic strain, the dynamic secant elastic modulus E_(sec of LCES increases and the damping ratio decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency. The curves ofσ_d～ε_d,E_～ε_d and D～ε_d with different EPS content intersect respectively, the trend of LCES deformation characteristic is inversely proportional to EPS content near the intersection. The value of dynamic strain at the intersection is about 0.5%~3.0%, the magnitude of which is related to the mixing proportions and confining pressure.

试验结果表明，LCES的动应力应变骨干曲线形态符合双曲线；在相同的动应力作用下，LCES产生的动应变随着固结压力、水泥掺量、试样养护龄期和振动频率的增大而减小；在动应变相同的情况下，随着固结压力、水泥掺量、试样养护龄期和振动频率的增大，LCES的动模量增大而阻尼比减小；随着加载次数的增大，LCES的动模量在开始阶段显著降低，然后趋于稳定，但当加载次数达到几百次时，动模量又有增大的趋势；不同EPS掺入比的LCES的动应力应变骨干曲线、动模量随应变变化曲线和阻尼比随应变变化曲线都发生了相交，交点前后EPS掺入比的大小对LCES动力变形特性的影响趋势是截然相反的，交点处的动应变值一般在0.5％～3.0％范围内变化，其大小与LCES的配比以及固结压力有关。

The joint effect of active and reactive power on the voltage stability of a typical power system was considered by analysing the two parameter bifurcation problem related to nonlinear oscillation phenomena. Numerically, as the active power P1 increases, the Hopf points get closer and eventually coincide at P1=1.455 43 the cyclic fold curve gets closer and closer to the Hopf curve and finally intersects the Hopf curve at a singular point the period-doubling points also get closer and finally coincide at P1≈0.65. The stability behaviour is pre-determined using the normal form approach near the limit point of the Hopf curve. Hence, in the power system attention should be paid to both the consumption of active power and the decrease in the reactive power to prevent nonlinear oscillations. A controller can be designed to absorb some active power and to avoid the nonlinear oscillations that damage the system components.
