1. In synchronous frame time, lines are geodesics in the four-dimensional spacetime.
2. Conversely, these properties can be used to construct synchronous frame in any spacetime.
3. Such a construct, and hence, choice of synchronous frame, is always possible.
4. An analytic transformation to synchronous frame can be done with the use of the Hamilton & ndash; Jacobi equation.
5. This indication, however, was dropped after it became clear that it is linked with a specific geometric property of the synchronous frame : the crossing of time line coordinates.
6. It's difficult to find synchronous frame in a sentence. 用synchronous frame造句挺難的
7. The Einstein equation } } written in synchronous frame gives a result in which the metric determinant " g " inevitably becomes zero in a finite time irrespective of any assumptions about matter distribution.
8. Choose these lines as time coordinate lines and define the time coordinate " t " as the length " s " of the geodesic measured with a beginning at the hypersurface; the result is a synchronous frame.
9. At that time, the only known indication was related to the form of the Einstein equations written in a synchronous frame, that is, in a frame in which the proper time " x " 0 = " t " is synchronized throughout the whole space; in this frame the space distance element " dl " is separate from the time interval " dt ".
