本课程为提供已有常微分方程式基础的同学修习、内容包括线性代数、矩阵运算、特徵值问题、向量的微分与积分、一阶线性微分方程组、傅力叶级数和正交函数、傅力叶转换、并将对椭圆、抛物线、双曲线型式的偏微分方程式作概略介绍。

The reason to do so is that the hyperbola intersection model is not a global convergence model, and bad initial coordinate can lead to divergency for the Least Square solutions.

由于双曲线定位算法是非全局收敛的算法，本文提出的基于解析算法用于求解初值可以大大避免系统的发散。

In the influencing factors of yarn, the yarn of less diameter have lessfiloplume, as adding twist, the filoplume lessen, on the other hand, adding twist increases the tightness of fabric, make the filoplume of fabric moving back harder, aggravate theprickle to skin. The relationship between the prickle and twist is double curve.

竹原纤维纱线的捻度与刺痒感成双曲线关系，一方面纱线表面毛羽量随捻度的增加呈减少趋势，刺痒感下降；另一方面，捻度增加，纱线紧度加大，纱线表面毛羽受外力后避让困难，对皮肤的作用力加大，加重刺扎感。

According to the relationship between hyperbola and its normal, the analytic equation is discussed.

根据双曲线与其法线的几何特征关系建立了求解法线的解析方程，分析了法线问题解析求解的繁杂性。

This paper introduces a method of the establishing theory of a-particles scattering,This treatment is given in preference to the more usual one because it does not require a Knowledge of the geometry of the hyperbola.

本文是介绍一种建立α粒子散射理论的方法。这种处理方法比常见的方法为好，因为它不需要几何学的双曲线知识。

The results show dynamic constitutive relationship of loess for 4 kinds of frequency submits to hyperbolic equation.

结果表明，对应于4种频率的原状黄土的动本构关系均服从双曲线模型，但试验常数a、b均随振动频率的增大而略有减小。

Special considerations are given to spatial discretization of hyperbolic equation with non self-adjoint operator nature.

同时构造了一个用于求解此耦合过程的统一混合弱形式，并且针对其中具有非自伴随算子特性的双曲线控制方程的空间离散进行了特殊考虑。

The miniaturization of the ion trap was achieved by using smaller pumps, a smaller vacuum system and lower RF voltage, as well as a simplified trap geometry (from hyperbolic to cylindrical, then to rectilinear).

离子阱的小型化是通过应用小型真空泵、小型真空系统及较低的射频电压和简化阱结构（从双曲线离子阱到圆柱型离子阱再到矩形离子阱）来实现的。

However, some properties of laser beams limit its further application. For example, its intensity distribution is Gaussian profile, not uniform one. And propagation path is hyperbolic line, not straight line.

激光束的光强呈高斯分布而不是均匀分布，它的传播路径是双曲线而不是直线，这些特性在某种程度上限制了它的应用。

He believes the form he is holding is a hyperbolic paraboloid, a shape well known to mathematicians - or something very close to that - but he wants to be able to prove this conjecture.

他相信他手中的摺纸形式是一种数学家所熟知的双曲线抛物面，或是某种非常接近的形式，於是他想要验证此推测。
