查询词典 imaginary point

This paper studys the stability of nonlinear systems in two particular critical cases. In a case, the linear systems at the equilibrium point of interest is assumed to possess a simple zero eigenvalue. In the other case, it is assumed to possess a complex conjugate pair of simple pure imaginary eigenvalue.

本文基于中心流形定理研究了非线性系统在两种特殊临界情形下的稳定性问题，一种是与它相应的线性系统在平衡点仅有零特征根，另一种是与它相应的线性系统在平衡点仅有一对共轭的纯虚数特征根。

But the saddle point in the imaginary plane should convolute here.

At the point at which that line intersects the ellipse, windows begins drawing an arc in a counterclockwise direction around the circumference of the ellipse. windows also uses an imaginary line to connect with the center of the ellipse.

在这条线与椭圆相交的点，windows 开始逆时针方向环绕椭圆的周围绘制一个弧。windows 也用一条假想的线连接和椭圆的中心。

By spectral analysis of the system, we find that 0 is the uniquespectral point of system on the imaginary axis.

同时通过研究系统算子的谱特征，证明了系统算子的谱点均位于复平面的左半平面且虚轴上除0外无谱，进而得到系统的渐近稳定性，特别在范数意义下系统的动态解收敛到稳态解。

That is, the singular terms: signal, point, sample, and value, refer to the combination of the real part and the imaginary part.

也就是说，单一的术语：信号、点、样本和数值指的是实部和虚部的组合。

Complex numbers are always represented as two floating point numbers, the real and imaginary part.

A real or imaginary mark or point at which a race begins or ends.

起始线，终点线：赛跑中起点或终点的实际或想象的线

This method needs no connectivity information about data points. The contradictory of "smooth" and "fit" can be mediated by anchoring an imaginary spring between each data point and deformable curve or surface.

该方法不必要求数据点有序的条件，通过在数据点与曲线和曲面之间连接假想弹簧，可以克服"光顺"和"插值"的矛盾，得到所需形状。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
