Submitted by lwz110911 on Wed, 03/26/2014 - 10:50 大家好： ALFF有没有明确的计算公式？就想ReHo那样。fALFF是在ALFF的基础上改进的，那它是不是也应该有着相近的计算公式？谢谢 Log in or register to post comments 6588 reads Submitted by ZHANG_RESTadmin on Wed, 03/26/2014 - 12:08 Permalink Re: 请问大家，关于ALFF有没有它的计算公式？ ALFF有计算公式的，Zang YF, He Y, Zhu CZ, Cao QJ, Sui MQ, Liang M, Tian LX, Jiang TZ, Wang YF.
