concept
Lorentz In order to explain Michael Sun-Morey experiment, the observer occurs, the observer occurs in the direction of motion relative to the moment of movement. The maintenance of the static length and the ratio of the neutral length and the length of the length of the longitude, but he believes that this does not have physical significance and treat it as a pure mathematical process. Einstein published in 1905, the paper entitled "Electric Power of the Argument", proposed the basic theory of narrow relativity.
Based on two basic assumptions: narrow relative principle and speed constant principle, the time and coordinate transform equations of the inertial dynamic relationship and the static system, that is, Lorentz transform, through Lorenz The transformation derived the following narrow relativity basic view:
-
The maximum speed of the light: any moving object is not exceeding the speed of light speed
-
: The moving object is shortened when the size of the moving object is relatively relatively stationary, and the slow slow time and space relative to the spare time and space of the moving objects are slower.
Definition
The rocky relationship given by the narrow relativity is the proportion of "detergent" "clock slow" proportional factor, the Lorenz factor, expressed as:
where C is a vacuum speed, V is the moving speed of the relative static system.
Application
The size reading of the object motion direction in the dynamic system is: L '= βL, L is the size of the static size
time reading To: t '= t / β, T is the time of the static system
intuitive class ratio
Based on the hypervisor of the Lorenz factor.
, a bunch of light is in any reference system, which is the same as any observer and speed.
can therefore appear in realities:
-
relative to the origin O, the moving points A and B leave the O point with speed V and C, The speed angle is α, then the relative speed of B is V '
, O, O two points measured the same conversion method -
The string of the parallelogram of the vector, the cosine theorem, V ', as shown.
-
there is transform factor β = c / v '= C / (C ^ 2 + V ^ 2-2cv * cosα) ^ 1/2
-
Based on OB, there are two options: ( 2 choice one )
-
change the measurement of the measurement AB distance The readings are multiplied by β ( ");
-
to change the reading of the clock of the AB time, except for β ( Clock slow ).
-
This can calculate V '= c
-
special circumstances: The above speed and angle of angle constitute the right angle relationship
-
can be β = c / v '= c / (c ^ 2-V ^ 2) ^ 1/2 , "in the relativism " Raw "," Clock Slow " core: Lorentz factor
-
can be seen that selecting a right angle relationship can eliminate the appearance of α. (Let Lorenz transform are only related to V and C, more universal.)
-
get revelation:
When it is determined on both sides and angles, the triangle has the only one, it can be
-
- < p> If Lorenz transform is the above-mentioned superimposed relationship,
-
Lorentz transform can only have a realistic three-dimensional space solution in the routine point, is a two-dimensional plane < / p>
-
Lorenz transform only for special angles with realistic three-dimensional space solution
-
Lorentz transform cannot be Little completion of the physical meaning
-
Unable to constitute a real three-dimensional physical space
in reality The change factor is used to change the number of minutes, not the time and length true change.

The transformation of the transformation and the clock is only one, and the relativity is considered to be equally. Of course, it is necessary to understand that relativity must understand the four-dimensional time and space, and its mathematical form is the geometric space of the Cocollsky.
