但大体IF的评价不受影响，虽然被诟病很多。

截止2016年7月15日，几个top期刊的即时IF如下。一般，web of science收录平均滞后1.5个月，相当于平均收录到5月底，所以明年的IF可以在即时IF的基础上乘以2.4

PRL: 18950/5290 = 3.58                       IF (2017) = 8.6
PRX: 2032/389 = 5.22                           IF (2017) = 12.5
(PRX now becomes very difficult to pass editors and starts to fly high...)

Nano Letters: 12417/2363 = 5.25           IF (2017) = 12.6
Nature Commun: 27144/5948 = 4.536    IF (2017) = 10.9
PNAS: 27783/6866 = 4.046                    IF (2017) = 9.7
AM: 16162/1955 = 8.267                       IF (2017) = 19.8

For comparision: [Scientific Reports: 23086/14583 = 1.58   IF (2017) = 3.8] 返回小木虫查看更多
