We explore the time evolution of microwave and hard X-ray spectral indices in two solar flares observed by the Nobeyama Radio Polarimeters (NoRP) and Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) on 2004 May 21 and November 3. The microwave spectral index, γMW, is derived from the emission at two frequency channels of 17 and 35 GHz, and the hard X-ray spectral index, γHXR, is derived from RHESSI spectra. These two events follow a soft-hard-harder spectral behavior in the rise-peak-decay phases. Although the microwave and hard X-ray emission are produced by electrons at very different energies, a correlation between their spectral indices is found, indicating a common acceleration mechanism.
