摘要
The Transition Region and Coronal Explorer (TRACE) gave us the highest EUV spatial resolution and the Ramaty High Energy Solar Spectrometric Imager (RHESSI) gave us the highest hard X-ray and gamma-ray spectral resolution to study solar flares. We review a number of recent highlights obtained from both missions that either enhance or challenge our physical understanding of solar flares, such as: 1. Multi-thermal Diagnostic of 6.7 and 8.0 keV Fe and Ni lines, 2. Multi-thermal Conduction Cooling Delays, 3. Chromospheric Altitude of Hard X-Ray Emission, 4. Evidence for Dipolar Reconnection Current Sheets, 5. Footpoint Motion and Reconnection Rate, 6. Evidence for Tripolar Magnetic Reconnection, 7. Displaced Electron and Ion Acceleration Sources.
