乘

This means that the cross product is zero, and therefore that the vectors are at right angles.

还这意味着叉乘为0，因此两向量（译注：矩阵中的行列代表的向量）相互垂直。

The required opeartion is called cross product, and it is represented by "x".

这个需要的运算叫做叉乘，我们把它表示为"X" v = v1 x v2

With the two vectors, v1 and v2, it is now possible to compute the cross product between them to find a perpendicular vector to the face.

有了两个向量v1和v2，现在我们就可以计算叉乘，来找到正交于面的一个向量。

The normal vector is computed as the "cross product" of two vectors that make up the side of the triangle.

法线是三角形两边的两个差乘结果。

Combined with vehicle handling dynamics, it also promotes dynamics simulation on crosswind stability in high speed.

为深入研究高速行驶侧风作用下乘用车气动特性以及结合汽车操纵动力学对侧风稳定性进行动力学仿真提供了有利的参考。

When King Crowdy Si Cheng midday nap, drips into in his ear with the poisonous herb juice, kills by poison king.

The module is 128 by 64 points the dot-matrix liquid crystal system can interface directly with the MCU.

该模块是128乘64点的点阵式液晶系统。可直接与单片机接口。

By using this method, the angular frequency, amplitude, initial phase angle, decay constant of each component in transient voltage and/or current waveforms can be precisely extracted. Also, all other kinds of transient procedure can be analyzed by this method. Thirdly, a new definition of generalized instantaneous reactive power and generalized instantaneous reactive current in dq0 coordinates under any nonsinusoidal and unbalanced three-phase circuit is proposed for the first time. The detection and compensation method for different instantaneous reactive currents are also concerned.

本文首先提出了用于快速高精度频谱分析的一种改进快速傅立叶变换方法，该法具有速度快、精度高、抗混迭、不受采样定理约束、可以分析出谐次大于N／2的频谱系数等特点，可方便地应用于电力系统谐波分析及其它各类频谱分析；然后提出了基于非线性最小二乘优化法的电力系统暂态波形分析方法，可准确求出电力系统暂态电压、电流波形中各个分量的角频率、幅值、初相角及衰减常数，并可广泛应用于各类暂态过程波形分析。
