Using singular value decomposition (SVD) method for soft X-ray emission and for electron cyclotron emission (ECE), the coupling spatial structures and coupling process between these two modes are analyzed in detail. The results of SVD for ECE reveal that the phase difference between these two modes equals to zero. This is consistent with the perfect coupling condition. Finally, performing statistical analysis of r1/1, ξ1/1 and w2/1, we find that r1/1 more accurately represents the coupling strength than ξ1/1, and r1/1 is also strongly related to the (2, 1) NTM triggering, where r1/1 is the width of (1, 1) internal mode, ξ1/1 is the perturbed amplitude of (1, 1) internal mode, and w2/1 denotes the magnetic island width of (2, 1) NTM.展开更多
