With the boundary point and the known adjacent relations, an overall marching procedure can go on and the iteration process stops until the intersection curve is self-closed or reaches the border of the composite surface. In the later case, the marching must be repeated from the starting point in the reverse direction until the intersection curve reaches the other border of the composite surface.

由一个交点出发，通过计算跟踪方向和跟踪步长，迭代计算出下一个精确的交点；利用边界点和近曲面点计算方法，根据曲面片的拓扑关系找到交线所经过的下一张曲面片，从而使跟踪过程继续下去，直至形成封闭交线环而停止该交线段的跟踪，或到达复合曲面的边界后由首交点反向跟踪到达复合曲面的另一边界。

Soil water characteristic curve was measured with a sand column for both drying and wetting processes, and the data were used to fit the van Genuchten model. The fitted curve is in good agreement with the actual measurements, residual water content and other factors used in the van Genuchten model were obtained. For the sand studied,. The results from this study may provide reference for research of water and solute movement in unsaturated soil.

利用Van Genuchten模型对用砂性漏斗测量中砂的吸湿过程和脱湿过程土壤水分特征曲线进行拟合，结果表明实测曲线和拟合曲线吻合很好，并得出Van Genuchten模型中的残余含水量、特性参数α和n，模拟计算表明，中砂有α=1.69α的关系，为研究水分和污染物在非饱和土壤中运移问题提供土壤水分运动键参数。

Through the characteristics analysis of compound curves for road project , it was proposed that the complex line forms can be simplified to straight line, circular curve and complete transition curve, it was also proposed that the middle and side piles can be used to lay off the control piles of the road construction,and fx-4500P calculator can be used for programming of laying off calculation.

通过对道路工程复曲线特征分析，提出复杂线形可简化为直线、圆曲线和完全缓和曲线三种线形，以及道路工程施工控制桩可采用中、边桩的办法进行测设的两种观点，并用fx-4500P计算器编写测设计算程序。

Results According to the score criteria of IBS curve patterns,when IBS curve score were 1 or 2,the magnitude of VIB nd CVIB% were between controlled groups and infracted groups,and comparison to the two there were significant difference,it is ischemic myocardium or viable myocardium.

评为1分及2分的心肌节段即IBS曲线形态评分≤2分者，其IBS周期变异幅度、IBS周期变异率%界于对照组和梗死组之间，且与该二者比较差异有显著性，考虑其为缺血心肌即存活心肌，占43.6%（17/39），但其IBS%与梗死组之间比较无统计学差异。

It is not enough if we just only depend on static yield curve of zero-coupon bond which reflects the current term structure of interest rate and make it the lever for financial products with uncertain cash flow, especially the measurement of interest rate risk on financial products with random cash flow which is related to interest rate, but need to set yield curve of zero-coupon bond as dynamic models.

对非确定性现金流金融产品，特别是与利率相关的随机现金流的金融产品进行利率风险度量，单纯依赖反映现行利率期限结构的静态零息票债券收益率曲线作杠杆是不够的，而是需要把零息票债券收益率曲线建成动态模型。

RCBV values calculated using cSVD and oSVD were identical. Both values were equal to the whole areas under the concentration-time curve were divided by the arterial input function areas. Moreover, these rCBV approximated to the rCBV calculated by signal-time curve fitting. rCBF with cSVD and oSVD wouldn't be underestimated by delay effect and were good for relative quantity. The scatter plots of rMTT and Td were useful in stroke staging.

cSVD和oSVD所得组织脉冲反应曲线的面积相等，均等於完整的浓度时间曲线下面积除以动脉输入函数下全部面积；而且，此结果和讯号时间曲线拟合很接近。cSVD和oSVD不会因延迟效应低估rCBF，可以良好反应不同组织的血流量相对值。rMTT和Td散布图在不同疾病种类或处於不同疾病分期，显示不一样的分布。

We discussed the total design of WEDM CNC programming system based on the Object Oriented Programming idea, studied the fitting method of a plane curve, used an efficient and stable curve approximating method; studied the planar translations of graphs and arc copulations between curves; discussed the interface technology to popular CAD software; discussed letters and images automatic programming system, and brought out a simple and convenient

Our study addresses the following topics:A conception of relative nonlinear measure on the equilibrium manifold parameter has been derived based on the definitions of equilibrium manifold and nonlinear measure about nonlinear system.And the nonlinear measure curve of a material boiler-turbine CCS model has been drawn.From the curve, we linearised the CCS nonlinear model and constructed the T-S fuzzy model of the unit by linking together the linear models of the unit with membership functions.

本文的研究内容集中在如下几个方面：根据非线性系统平衡流型和非线性测度的定义，提出了关于平衡流型参数的相对非线性测度的概念，据此绘出了一个具体单元机组机炉协调控制系统模型的相对非线性测度曲线，对此协调控制系统非线性模型进行了线性化，并用隶属度加权的方法将各线性化模型连接成协调控制系统T-S模糊模型。

But the errors with the Fourier transform method are -1062nT/m and 1442nT/m, there is large departure between the calculating curve and theoretical curve and evident influence by effective magnetic dip angle in computing.

而Fourier变换法计算的水平和垂向一阶导数最大误差分别为-1062 nT/m、1442 nT/m，计算曲线与理论曲线偏离大，受磁化倾角的影响也较大。

I urge any American living outside the country to get an early start checking his/her registration and receiving an absentee ballot, because it can take a while.

我奉劝身在国外的所有美国人早点着手核对登记表，并接收缺席选举人票，因为这得花点时间。

He is too young to join the army.

他太年轻了，还不能参军。
