Using a potential model with relativistic correction we evaluated the spectrum, le-pton decay widths and radiative transition widths of heavy quarkonium systems.
The fading correction and its corresponding calculation method were specially introduced in this paper for improving the accuracy of the environment cumulate kerma.
A system of verifying anemoscope in tobacco specific smoking machine was designal.The theory and component parts of this system was introduced and the method of velocity at a fixed point was modified.
