Diffrent Tc could be got, but difftent according to diffrent degauss value and diffrent mu(Coloum coefficient in the modified). My questions are: (1) how to specify the degauss value and mu value as well as the smearing method? (2)how to select the Tc from diffrent value, how to know the Tc is convergent?</span><div> <span style="line-height: 19.6px;">Best</span></div><div><span style="line-height: 19.6px;"> ouyang</span></div></pre><h2 style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 1.16em; color: rgb(67, 67, 67); font-family: Tahoma, Arial, 宋体, 'Malgun Gothic'; line-height: 24px; widows: auto; background-color: rgb(242, 242, 242);"><br></h2><br><br><br><br><div style="position:relative;zoom:1">--<br><div> </div>
