摘要：

In this Letter, we present a wavelet analysis of the 13CO spectral data of the L1551 outflow region. We show in particular that the fractal Hausdorff dimension of the data space consisting of the centroid velocities over the R.A.-decl. plane is well defined as 2.35 ± 0.01. In addition, it is suggested that the scaling law for the Gaussian line widths may be different, namely Δσv ∝ l0.7. The analysis of the column density leads us to believe, however, that there is a substantial quantity of gas between the emissivity peaks.
