虚数单位

Imaginary unit, real part , imaginary part , the algebraic form of complex numbers.

给出复数、虚数单位，实部、虚部、复数的代数形式。

Based on a brief review on developments of number system, a new developed pattern is proposed. The quaternion is extended to a matrix form aI+bA+cB+dC, in which the identity matrix I and three special matrices A, B, C correspond to number 1 and three units of imaginary number i, j, k, respectively.

在数系发展的基础上，提出了一种新的发展模式：四元数推广为矩阵形式aI+bA+cB+dC，其中单位矩阵I和3个特殊矩阵A，B，C分别相应于数1和虚数单位i，j，k。

Gas is composed of electromagnetic and other material, a substance which can be imaginary unit i said that the square root of negative one, that is, the virtual and physical entities of the computing complex material, which is the process of mutation of the actual process of change, with acupuncture points on this Characteristics of species, the meridian acupuncture points of the different substances in different proportion, that is, electromagnetic and the proportion of complex material, they have a different God.

气是有电磁和其他物质组成，其中有一种物质可以用虚数单位表示i负一的开平方，就是虚的物质与实体物质的运算复数，也就是突变过程虚实的变化过程，穴位就具有这种特性，经络穴位的不同其物质的比例也不同，就是电磁与复数物质的比例也不同，其所产生的神也不同。

The definition of Wavelet Analysis is that shifting the mother wavelet e.g. which has limited energy, such as shifting for, then proceeding dimensions, we obtained wavelet basis function ,, which make the inside product to the function to analysis With the Fourier transformation to the and, then the equivalent frequency spectrum of wavelet transformation can be expressed as where 、 are the transformations of 、 respectively and i is an imaginary number unit.

小波变换的含义是：把一具有有限能量的母小波，如进行移位后，再进行尺度的伸缩得到小波基函数为然后与待分析的函数作内积，即对和作Fourier变换后，可得到小波变换的等效频域表示为：其中、分别是、的Fourier变换，i为虚数单位。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
