We study non-thermal emissions by relativistic electrons from　supernova remnants(SNRs) in the presence of small-scale random and large-scale regular magnetic fields. We extend our pure jitter and inverse Compton emission models (Ogasawara et al. 2006) and construct the emission models with regular magnetic fields. We apply them to the multi-wavelength data of TeV gamma-ray sources SNRs RX J1713.7-3946 (G347.3-0.5) and RX J0852.0-4622 (G266.6-1.2). The physical fit parameters of random and regular magnetic fields are discussed.
