4. Conclusions

The correlation between the coronal temperatures and the photospheric magnetic field strength has been investigated. Some primary conclusions can be presented here: 1) There is a correlation between the high-temperature component and the magnetic field strength for single stars, which suggest that the high-temperature component is heated by the magnetic field. From this result, we can estimate the magnetic field strength for single stars from the X-ray spectrum. We hope the future observed magnetic field can be compared with our estimation. 2) There is no correlation for the low-temperature component for single stars, the reason is that the low-temperature component is heated acoustically. 3) There is no correlation for binaries and RS CVns. 4) The best fit is the two-temperature model with intervening absorption.
