| 1 | The programs implemented in either software and (or) firmware that makes the computer hardware usable. | |
| 2 | Bremsstrahlung and compound radiation of electron were considered as main mechanism of continuum radiation. | |
| 3 | The results indicated that the criterion is between 3 and 60 when the bremsstrahlung and scattering process are both concerned. | |
| 4 | Bremsstrahlung and compound radiation of electron were considered as main mechanism of continuum emission. | |
| 5 | In this paper we calculate the scattering matrix S(T, -T) for the bremsstrahlung process, here 2T is the effective interaction time of the bremsstrahlung process. |
