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 ( CVD ) , 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 \pm 0.05 ) \times 10 ^ { 33 } ~ { } { erg~ { } s ^ { -1 } } is similar to those from dimensional analysis and also consistent with the previous energy injection rate based on molecular outflows and bubbles .
