摘要：

We have measured the speed of second sound u(2) in He II in the presence of a heat flux Q. For T-lambda - 1 mK > T > T-lambda -3.5mK it is found that u(2) reduces linearly with Q(2), for 2 mW/cm(2) < Q < 6 mW/cm(2). By extrapolating the data we have deduced that the lambda transition temperature reduces linearly with Q.
