1·R wave has characteristic dispersion in layered media.

2·R wave velocity is mostly relative to the nature of media in which wave can penetrate.

3·Objective To estimate clinical significance of poor R wave progression in precordial leads.

4·In passive millimeter wave image restoration, L-R algorithm is a simple and effective nonlinear method.

5·The variation of R wave amplitude has little relation with cardiac output, heart pumping function, especially with pulmonary wedge pressure.

6·The detection algorithm that adopts tow-level finite difference and extremal theory is used to locate the R wave and the one-level and tow-level derivative methods is used when detect QRS wave.

7·So we have the operationon the wave function in terms of r, theta, and phi and remember this e is just our binding energy for the electron, and we get back out this wave function.

8·This paper transplants a program for slamming moment and wave exciting moment, and utilizes the B-R criterion.

9·We also obtain the variation of the radial dispersion of velocities with r through the stability of the density wave in three-dimensional dishlike galaxies.

10·Besides that, we presents the gravitational wave energy density under the weak field situation and gives the x - y plane numerical calculation to curvature scalar R and energy density .
