Then, in the coordinate that previous definition, variation of square of time value is equal to variation of square of space value . This
is
space-time’s symmetrical variation. It means

Next, use four-dimensional space-time’s reference frame of General relativity to find the Schwarzchild solution, then contrast the theory

its physical meaning is that the physical condition between proper time and

So,

So,
