摘要：

Recent estimates of magnetic field strengths in T Tauri stars yield values of B = 1-4 kG. In this Letter, I present an upper limit to the photospheric values of B by computing the equipartition values for different surface gravities and effective temperatures. The values of B derived from the observations exceed this limit, and I examine the possible causes for this discrepancy.
