英文摘要	There are two explanations for the broadening mechanisms of the Ca XIX resonance line in the rising phase of a solar flare. One is due to the velocity dispersion of the chromospheric evaporation along the loop; the other is due to the non-thermal turbulence resulting from the flare energy release. In this paper we distinguish between these two possibilities by studying the influence of the loop orientation on the broadening of the Ca XIX resonance line, based on the data observed with SXT and BCS on Yohkoh. The results seem to support that the broadening of the Ca XIX resonance line is caused by non-thermal turbulence, rather than by the velocity dispersion.
