The relativistic correction due to earth rotation for both terrestrial and satellite time comparison experiments via laser pulses has been discussed and a practical calculation formula is proposed.
The radiation spectrum for relativistic electron moving along curved spiral curve in plasmas is calculated, and also the formula of total energy emitted by a relativistic electron in vacua is derived.
