摘要：
Synthetic heating of solar coronal loops combining Joule and wave-heating mechanisms on current sheets is proposed. The formation of singular current structures such as current sheets can be caused not only by magnetic reconnection and footpoint convection of coronal loops, but also Alfven resonance induced by shear flows. On the other hand, with the two-fluid effect, the kinetic Alfven wave can also be excited on such current structures. Therefore, a synthetic energy dispassion process of both collisional and wave-heating mechanisms on the current structures may lead to a better understanding of the coronal-heating problem.
