摘要：

The magnetic penetration depth formula in MgB2 is more complex than that in BCS superconductors due to the existence of exotic two energy gap in MgB2. A new simplified relationship between the penetration depth and temperature is presented, which is derived from the two-fluid model by means of numerical fitting method, and the physical meaning is relatively clear.
