英文摘要Turbulence dissipation is an important process affecting the energy balance in molecular clouds, the birth place of stars. Previously, the rate of turbulence dissipation is often estimated with semi-analytic formulae from simulation. Recently, we developed a data analysis technique called core velocity dispersion, which, for the first time, provides direct measurements of the turbulence dissipation rate in Taurus, a star-forming cloud. The thus measured dissipation rate of (0.45 +/- 0.05) x 10(33) erg s(-1) is similar to those from dimensional analysis, and is also consistent with the previous energy injection rate based on molecular outflows and bubbles.
