Real Number(实数):

Imaginary Number(虚数):

Complex Number(复数): 公式：

    a: a real number

    b: a real number

    i: imaginary unit,

Complex Plane(复平面): The complex plane is the plane formed by the complex numbers, with a Cartesian coordinate system such that the x-axis called real axis, is formed by the real numbers, and the y-axis, called the imaginary axis, is formed by the imaginary numbers.

Real Axis(实轴): The line in the complex plane corresponding to zero imaginary part.

Imaginary Axis(虚轴): The vertical line in the complex plane, every point on which corresponds to a complex number having zero real components.
