Cataclysmic Variables (CVs), as the famous accreting white dwarf systems, are composed of a white dwarf primary accretes materials from a Roche-lobe filling late-type star via the inner Lagrangian (L1) point. The excellent databases with nearly continuous photometric coverage from many spaced-/grounded-based surveys (e.g., the Kepler-I/II, ZTF, TESS etc.) provide an unprecedented chance to investigate the stabilities of the accretion pattern in quiescent and outburst CVs based on the improved orbital modulations. With a uniform morphologic accretion model, composed of a main disk and two possible hotspots respectively at the vertical side of the disk edge and on the disk surface is used to explain the orbital modulations. More details on a complete evolution scenario of the quiescent disk surrounding a superoutburst provides strong observation evidences supporting current theories of the disk instability models. The stabilities of two types of non-magnetic white dwarf accreting outbursts: normal and super-outburst are further investigated using wavelet and Hilbert-Huang Transform.
