 section curve
 The absolute total ionization cross section curve obtained is in excellent agreement in shape and magnitude with the low energy data (>amp;lt;200 eV) of Djuric et al. The formula proposed is not suitable to reproduce the exact contour of fine structures in the ionization cross-section curve. The cross section curve deduced is compared with an impulse approximation calculation including a volume and a surface production model. A structure was observed in the27Al(n, α)24Na reaction cross section curve around 14 MeV neutron energy. Concerning the onset of chaos, it is found that the appearance of bumps and foldings in the section curve is the cause of the breaking of the torus. 更多
 Aim To determine the measured profile of a wheel in railway vehicle.Methods So- called piecewise curve-fitting method of the third derivative continuity is employed . Results The formulas of the piecewise curve fitting method were derived the curve-fitting profile of a wheel looks very fine and its first to third derivatives are also smooth.Conclusion The new piecewise curve fitting method is fine enough to fit the measured profile data of a wheel for the purpose of vehicle system dynamic analysis. 目的拟合列车车轮踏面的实恻轮廓曲线，方法采用三阶导数连续的分段曲线拟合法。结果推导出了三阶导数连续的分段曲线拟合法的公式，得出了车轮踏面轮廓实测数据的拟合曲＊线，不但拟合曲线的拟合精度高而且拟合曲线的一阶到三阶导数也很光滑。结论用该三阶导数＊连续的分段曲线拟合法拟合实测的车轮踏面可以满足对车辆系统动力学分析的要求。 In this paper we consider the FLP problem in product Fuzzy decision . Generally, it is difficult to substitute product for intersection operation, because this will cause a nonlinear programming and the solution to this is very difficult. The literature [1] points out that the graph of on [0,1] is a sectional continuous curve, and that each section is quadratic convex arc. The product optimal solution is the demarcation points in (0,1). This paper points out that if has arrest point then it is unique and the... In this paper we consider the FLP problem in product Fuzzy decision . Generally, it is difficult to substitute product for intersection operation, because this will cause a nonlinear programming and the solution to this is very difficult. The literature [1] points out that the graph of on [0,1] is a sectional continuous curve, and that each section is quadratic convex arc. The product optimal solution is the demarcation points in (0,1). This paper points out that if has arrest point then it is unique and the arrest point should be an optimal point. 研究了FLP问题的积Fuzzy判决，一般认为：在Fuzzy判决这一步中，用乘积来代替交运算导出的规划往往是非线性的，求解比较困难[3]。文献[1]指出在[0,1]上的图形是连续的分段曲线，每段是二次凸弧，积最优解必在（０,１）内的分界点或驻点取得。本文给出的结论是：若有驻点，则驻点是唯一的，且该驻点就是最优点。 A new piecewise curve fitting method based on Least-Square principle.The mathematical model and the application of the method is discussed.An example is presented and the resulting fitting-curve with good fitting of precision and location is obtained by using the software MATLAB.The proposed principle is tractable, and the corresponding mathematical model can be easily solved by using existing software MATLAB. 在最小二乘原理的基础上,运用实测数据点的分段曲线拟合法,探讨相应的模型以及用不同类型的曲线同时拟合数据点的具体应用;对一实例,应用MATLAB编程设计,完成模型的求解、显著性检验等,可以得到拟合精度比较高的拟合曲线。该方法原理简便,其模型易用MATLAB编程求解。 << 更多相关文摘
