It is hard to draw in two dimensions a picture of a vector function in three-dimensional space . 在两维图上画三维空间的矢函数图形是件难事。
This last property illustrates why, in general, three-dimensional space is required for the geometrical realization rather than two-dimensional space . 这后一性质说明了为什么几何实现一般需要用三维空间而不是二维空间。
The knotted periodic trajectories in three - dimensional space 空间扭结周期轨道
The quasi - administrative act under the three - dimensional space 第三维空间下的准行政行为
A few arrays have three dimensions , such as values in three - dimensional space 三维有些数组有三个维,如三维空间中的值。
Reflection coefficients and transmission coefficients of the plan wave projecting material interface in three - dimensional space 三维物性界面的反射与透射系数及其数值计算
How to reconstruct the three - dimensional structure of conic curve in three - dimensional space from translation parameters is discussed 给出了恢复空间二次曲线参数的算法思路。
Like all machines , it operates in three - dimensional space , and it has distinct and dynamic interacting parts 一如任何机器,基因组也在三维空间内运作,且具有性质不同但积极互动的组成。
We discussed the three - phase four - legged inverter with a novel three - dimensional space vector modulation ( 3d - svm ) in this paper 本文的研究对象是采用了三维空间矢量控制的三相四桥臂逆变器。
One might conclude that the expansion of our three - dimensional space requires the presence of a fourth dimension 所以有人也许会急著下断语说,我们所处的三维空间,要膨胀就要有第四个维度存在。
