Barsky[4 ] 将具有张力参数样条的双曲样条曲线引入CAGD ，称之为张力样条参数曲线，并证明了这种曲线是一类泛函问题的极小解。

In the traditional reservoir operation system, in general, we use the rule curve as a method of operation, and the reservoir rule curve is the result of system simulation method. Due to the regular and simple rule curve operation unable to satisfy the actual demand effectively. In order to improve the defect, there are many system planning theories and optimum seeking methods to find the optimum operation strategies. The reservoir operators are uncomfortable with the complicated optimum operation strategies. In this article the fuzzy inference model is used to establish a simple and effective operation rule for the reservoir operator.

在传统的水库操作系统中，一般都使用操作规线为操作方式，水库操作规线是系统模拟法所获得的结果，由於规律、简单的规线操作方式往往无法有效满足实际需求，为了改善传统操作上的缺点，近多有利用系统规划之理论，应用各种优选方法求取最佳操作策略，系统最佳操作策略其模式复杂，水库操作人员不易接受，故本文即以模糊推论系统建立一简单有效之操作规则予水库操作人员，作为水库操作放水之依据。

The results are much better than the other approaches'. Then we give another method for approximating offset curves. The circle is first approximated by regular polygon within some tolerance. The exact offset curve is then approximated by the convolution of the regular polygon with a B-spline curve or a NURBS curve having the same degree.

与此同时作者从基圆的正多边形逼近出发，通过求解包络的技巧给出了等距曲线逼近的另一个算法，可整体估计误差，所得的等距逼近曲线为与基曲线同次数的B样条或NURBS曲线，克服了国际上现有同类算法中逼近曲线次数几倍于基曲线次数的缺陷。

Capital accumulates the motion curve that is market economy, unemployed population is the inevitable result that capital accumulates, the work population motion curve that also is market economy at the same time; Allocate be market economy to allocate the rule by element function, polarization of the rich and the poor is the inevitable result that allocates regular action by element; Inflation is the motion curve of market price case and money.

资本积累是市场经济的运动规律，失业人口是资本积累的必然产物，同时也是市场经济的劳动人口运动规律；按要素功能分配是市场经济的分配规律，贫富两极分化则是按要素分配规律作用的必然产物；通货膨胀是市场价格和货币的运动规律。

Through the new research methods, this thesis has made the following contributions in this field: 1. For the first time the curvature radii and relative angles of a planar continuous curve at discrete points are chosen as local parameters to represent the curve, which reflect clearly the local geometrical characteristics of the curve and are easy to be dealt with.

借助于新的研究方法，本文在这一领域作出如下贡献：（1）首次提出用曲线上离散点处曲率半径和相对转角作为局部参数表示平面连续曲线，直观地反映曲线各个局部的几何特征，且便于曲线的修改和变换，并通过机构运动分析，快速求出机构轨迹的这两个局部参数。

Because of the dependence of rotating dipole PA curve on layer of field lines, it avoids the degeneracy problem of conventional rotating vector model that all layers of field lines have the same PA curve with fixed inclination and impact angles, therefore it provides a useful way to identify the emission from different layers and constrain the location of emission regions in pulsar magnetosphere by fitting the observed pulsar radio PA data with rotating dipole PA curve.

其与磁力线层等参数的依赖关系避免了传统旋转矢量模型的简并问题－在给定磁倾角和碰撞角情况下所有层磁力线的偏振位置角曲线都一样，这为通过拟合射电偏振观测数据来分辨不同层的辐射，从而限定脉冲星辐射区部位提供了一条有用的途径。
