We explore the spectral behaviors of microwave and hard X-ray emissions in two solar flares observed by the Nobeyama Radio Polarimeters (NoRP) and the Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) on 2003 May 29 and 2004 January 6. The microwave spectral index γMW is derived from the emissions at two frequency channels of 17 and 35 GHz, and the standard RHESSI data analysis is used to derive the hard X-ray spectral index γHXR. The 2003 May 29 flare displays a soft-hard-soft spectral behavior in the hard X-ray rise-peak-decay phases, but a soft-hard-harder pattern in the microwave emission. The 2004 January 6 flare shows several soft-hard-soft spectral behaviors in its hard X-ray subpeaks, but only one soft-hard-soft pattern in the microwave emission from start to end. The imaging observations show that the thermal emission could be an important contribution to microwave spectral hardening with the time.
