我用CHI660C测量了电镀过程，出现了一个奇怪的Nyquist图，请教高手分析一下，测量的数据如下： Freq/Hz, Z'/ohm, Z"/ohm, Z/ohm, Phase/deg 9.668e+4, 2.205e+2, 2.857e+0, 2.205e+2, 0.7 8.105e+4, 2.154e+2, 2.715e+1, 2.171e+2, 7.2 6.641e+4, 2.053e+2, 5.251e+1, 2.119e+2, 14.3 5.469e+4, 1.861e+2, 6.411e+1, 1.968e+2, 19.0 4.590e+4, 1.711e+2, 8.348e+1, 1.903e+2, 26.0 3.711e+4, 1.487e+2, 9.008e+1, 1.739e+2, 31.2 3.125e+4, 1.290e+2, 9.253e+1, 1.587e+2, 35.7 2.539e+4, 1.085e+2, 9.645e+1, 1.452e+2, 41.6 2.148e+4, 9.058e+1, 9.197e+1, 1.291e+2, 45.4 1.758e+4, 7.444e+1, 8.561e+1, 1.134e+2, 49.0 1.465e+4, 6.120e+1, 7.858e+1, 9.960e+1, 52.1 1.172e+4, 4.810e+1, 6.875e+1, 8.391e+1, 55.0 9.668e+3, 1.894e+1, 3.285e+1, 3.792e+1, 60.0 8.105e+3, 2.238e+1, 2.534e+1, 3.381e+1, 48.5 6.641e+3, 1.720e+1, 2.156e+1, 2.758e+1, 51.4 5.469e+3, 1.478e+1, 1.929e+1, 2.430e+1, 52.5 4.590e+3, 1.536e+1, 1.476e+1, 2.130e+1, 43.8 3.711e+3, 1.380e+1, 1.240e+1, 1.855e+1, 41.9 3.125e+3, 1.525e+1, 9.582e+0, 1.801e+1, 32.1 2.539e+3, 1.396e+1, 7.307e+0, 1.576e+1, 27.6 2.148e+3, 1.418e+1, 4.770e+0, 1.496e+1, 18.6 1.758e+3, 1.403e+1, 2.912e+0, 1.432e+1, 11.7 1.465e+3, 1.398e+1, 1.256e+0, 1.404e+1, 5.1 1.172e+3, 1.429e+1, -1.155e+0, 1.434e+1, -4.6 9.668e+2, 1.450e+1, -3.878e+0, 1.501e+1, -15.0 8.105e+2, 1.469e+1, -5.748e+0, 1.578e+1, -21.4 6.641e+2, 1.510e+1, -7.953e+0, 1.707e+1, -27.8 5.469e+2, 1.539e+1, -1.046e+1, 1.861e+1, -34.2 4.590e+2, 1.581e+1, -1.283e+1, 2.036e+1, -39.1 3.711e+2, 1.652e+1, -1.630e+1, 2.321e+1, -44.6 3.125e+2, 1.705e+1, -1.922e+1, 2.569e+1, -48.4 2.539e+2, 1.790e+1, -2.367e+1, 2.968e+1, -52.9 2.148e+2, 1.864e+1, -2.754e+1, 3.325e+1, -55.9 1.758e+2, 2.002e+1, -3.335e+1, 3.890e+1, -59.0 1.465e+2, 2.136e+1, -3.924e+1, 4.467e+1, -61.4 1.172e+2, 2.321e+1, -4.809e+1, 5.340e+1, -64.2 9.766e+1, 2.626e+1, -6.579e+1, 7.084e+1, -68.2 8.138e+1, 2.957e+1, -7.794e+1, 8.336e+1, -69.2 6.975e+1, 3.295e+1, -9.337e+1, 9.901e+1, -70.6 5.744e+1, 3.813e+1, -1.112e+2, 1.176e+2, -71.1 4.650e+1, 4.425e+1, -1.321e+2, 1.393e+2, -71.5 3.756e+1, 5.230e+1, -1.572e+2, 1.657e+2, -71.6 3.150e+1, 6.174e+1, -1.860e+2, 1.960e+2, -71.6 2.570e+1, 7.506e+1, -2.197e+2, 2.322e+2, -71.1 2.123e+1, 9.240e+1, -2.583e+2, 2.743e+2, -70.3 1.744e+1, 1.145e+2, -3.043e+2, 3.251e+2, -69.4 1.436e+1, 1.478e+2, -3.743e+2, 4.025e+2, -68.5 1.191e+1, 1.746e+2, -4.112e+2, 4.467e+2, -67.0 9.766e+0, 2.238e+2, -4.702e+2, 5.208e+2, -64.5 8.071e+0, 2.791e+2, -5.389e+2, 6.069e+2, -62.6 6.643e+0, 3.645e+2, -5.852e+2, 6.895e+2, -58.1 5.486e+0, 4.370e+2, -6.860e+2, 8.134e+2, -57.5 4.542e+0, 5.387e+2, -7.581e+2, 9.300e+2, -54.6 3.742e+0, 6.646e+2, -8.364e+2, 1.068e+3, -51.5 3.090e+0, 8.017e+2, -8.868e+2, 1.196e+3, -47.9 2.550e+0, 9.308e+2, -9.366e+2, 1.320e+3, -45.2 2.105e+0, 1.107e+3, -9.425e+2, 1.454e+3, -40.4 1.738e+0, 1.340e+3, -9.320e+2, 1.632e+3, -34.8 1.434e+0, 1.439e+3, -9.191e+2, 1.708e+3, -32.6 1.184e+0, 1.600e+3, -8.611e+2, 1.817e+3, -28.3 9.766e-1, 1.715e+3, -8.006e+2, 1.893e+3, -25.0 8.071e-1, 1.847e+3, -7.198e+2, 1.983e+3, -21.3 6.643e-1, 1.918e+3, -6.652e+2, 2.030e+3, -19.1 5.486e-1, 2.008e+3, -5.855e+2, 2.092e+3, -16.3 4.542e-1, 2.080e+3, -5.083e+2, 2.141e+3, -13.7 3.742e-1, 2.124e+3, -4.360e+2, 2.168e+3, -11.6 3.090e-1, 2.184e+3, -3.930e+2, 2.219e+3, -10.2 2.550e-1, 2.211e+3, -3.402e+2, 2.237e+3, -8.7 2.105e-1, 2.254e+3, -2.863e+2, 2.272e+3, -7.2 1.738e-1, 2.264e+3, -2.562e+2, 2.279e+3, -6.5 1.434e-1, 2.301e+3, -2.311e+2, 2.312e+3, -5.7 1.184e-1, 2.321e+3, -2.123e+2, 2.330e+3, -5.2 9.766e-2, 2.335e+3, -1.376e+2, 2.339e+3, -3.4 8.071e-2, 2.358e+3, -1.515e+2, 2.363e+3, -3.7 6.643e-2, 2.368e+3, -1.379e+2, 2.372e+3, -3.3 5.486e-2, 2.377e+3, -1.240e+2, 2.380e+3, -3.0 4.542e-2, 2.388e+3, -1.105e+2, 2.390e+3, -2.6 3.742e-2, 2.378e+3, -1.050e+2, 2.380e+3, -2.5 3.090e-2, 2.371e+3, -1.006e+2, 2.374e+3, -2.4 2.550e-2, 2.352e+3, -1.024e+2, 2.355e+3, -2.5 2.105e-2, 2.352e+3, -1.042e+2, 2.354e+3, -2.5 1.738e-2, 2.362e+3, -1.071e+2, 2.364e+3, -2.6 1.434e-2, 2.239e+3, -9.710e+1, 2.241e+3, -2.5 1.184e-2, 2.185e+3, -9.619e+1, 2.187e+3, -2.5 |
