查询词典 imaginary number

Cardano's Ars Magna is a landmark in the history of mathematics. It started the theoretical research on algebraic equations, solved the polynomial equations of third-degree and forth-degree in a general and systematical way, and studied the imaginary number as well as its operations for the first time.

卡尔达诺的《大术》在数学史上具有重要的地位，它开创了代数方程的理论研究，首次系统地给出了三、四次多项式方程的一般解法，并且最早讨论了虚数及其运算。

Using bi-imaginary number representation, complex multiplication is simplified into two multiplication, instead of four ones in the previous method.

为克服空间带宽积的限制，提出了利用有限的外积乘法单元，通过矩阵分块和矢量循环流动进行任意维数矩阵与矢量运算算法，处理器利用率高。

They are maybe be understood as imaginary number i.

与0一样难以理解的还有∞、 i 这类概念。

Is scientifically same as imaginary number i. They are all symbols.

∞在科学上可以和虚数 i 一样，都只是一个符号，当我们利用虚数进行运算的时候，0、∞也同样可以。

So I is an imaginary number.

所以i是一个虚数并不真正存在

Of, relating to, involving, or being an imaginary number .

虚数的；与虚数有关的；包括虚数的

It can be considered that there are separate 0 space, entity space,∞ space, imaginary number space and assembled space, etc.

可以认为，科学上存在单独的0空间、实体空间、∞空间、虚数空间，及组合空间等。

As a result, is a time machine, and on the basic definition of space-time physics and the foundation will not waver, only the imaginary number exists in the points on the line.

因此，人是一种时间机器，而关于时空的基本定义和物理学的根基也不会动摇，只是改虚数存在于点内就行。

A special case,that the effective Fresnel number turns out to be a pure imaginary number,was discussed,and it is indicated that the simple formula evaluating the relative focal shift is still valid in this case.

还讨论了一种特殊等效菲涅耳数为纯虚数情况。结果证明，在这种情况下，该相对焦移简单公式仍然有效。

Regarding (6) type, when tradition Time variable t is two spatial vectors (+ psi 1i) and (- psi 2j) Crossed products v also is not 0, it (x1, x2, x3) differs 90 compared to on speed with the three-dimensional space in the space by the pure imaginary number attribute, I=e^I pi, therefore it Number space has in the physical property with the dot product constitution the difference, because Crossed products psi 1i (X psi 2j extremely small visible it is equal to zero under the conventional speed, but is very big in the object movement speed time, Crossed products psi 1i (X psi 2j in the physical quantity and for the quantum mechanics in may not to the easy quantity, its space and the conventional space is different, the performance is intrinsic or the interior space If the definition vector (+ psi 1i) and (- psi 2j) the dot product constitutes the three-dimensional space (x1, x2, x3) is exterior space, but the three-dimensional space which (+ psi 1i) and (- psi 2j) Crossed products constitutes by the vector is the internal space, contrasts its component

对于⑥式，传统时间量t为两个空间矢量(+ψ1i)与(-ψ2j)的叉积比上速度v且不为0，其与三维空间(x1，x2，x3)在空间上相差90度以纯虚数表征，I=e^Iπ，故其与点积构成的实空间有物理性质上的不同，因为在常规速率下叉积ψ1i(Xψ2j非常小可视其等于零，而在物体运动速率很大时，叉积ψ1i(Xψ2j之中物理量与则为量子力学中的不可对易量，其空间与常规空间不同，表现为一个内在或内部性空间。若定义矢量(+ψ1i)与(-ψ2j)点积所构成的三维空间(x1，x2，x3)为外部空间，而由矢量(+ψ1i)与(-ψ2j)叉积而构成的三维空间为内部空间，对比其分量
