Radiometri

Määritelmä

Moodin ja säteilykulman kaksi peruselementtiä, joita edustaa monikkokolmio, ja monikkoa vastaavaa vektorin pituutta kutsutaan monikon, vektorin ja todellisen akselin suuruudeksi. Kulman kulma on inkluusiokulma. Säteilyn koko on ääretön, mutta radiomor on yksilöllisesti määritetty.

Due to a plural

can be determined by the ordered real number to

, an ordered real number pair with a plane right angle coordinate system

Correspondingly, the plurality of points can be represented by the point

of the coordinates, at this time, the point of the

axis corresponds to the real number, The point of the

axis, the point on the

axis (except for origin) corresponds to the pure amount, namely the

axis is a virtual axis, as in this way The plane of the plural is called a complex.

multiple

axis. In this way, the plural

establishes a corresponding relationship with the vector

on the plane.

vector

is called the mode or absolute value of the plural

, record

, so

is not the original point, ie, multiple

, vector

and

The angle of the axis is referred to as the radiation angle of the plural

, which is recorded as

. The symbols of the radiation are specified as: from the front-axis inverse clockwise direction to

is positive, and it is negative in

as a negative.

Obviously a non-zero-recollection

has an endless multiple values, they differ in the integer multiple of

, but

There is only one value

satisfying the condition

, called

is the radio angle of the plural

, records

, So

When

, the radiation angle of

is meaningless.
