　　南京大学特聘教授刘俊明的学术道德亦存在严重问题（二）

　　作者：百合愤怒了

　　4.赤膊上阵，一稿两投

　　如果说刘俊明1996年的时候一稿两投还有点“抖乎”，知道要“乔作粉饰”，
那么，几年之后摸清了“江湖”门道的他，对于一稿两投就不再抖乎了，看看他
在1999发表在FERROELECTRICS上的论文“Monte-Carlo simulation of the P-E 
hysteresis and domain switching in ferroelectric Potts lattice”和2000
发表在APPLIED PHYSICS A上的论文“Dynamic hysteresis for Potts spin 
system: a Monte Carlo simulation”就知道，他已经懒得再从文法上“下功夫”
了。不信？你看看摘要好了（资料来源：web of science）：

　　Title: Monte-Carlo simulation of the P-E hysteresis and domain

　　Abstract: A Monte-Carlo approach based on the Q-state Potts model 
is developed to simulate dynamic hysteresis of ferroelectric Potts 
lattice against periodic time-varying external field E. The dynamic 
responses of the hysteresis dependent of frequency omega of applied 
field and domain size R are studied. The P-E loop exhibits very 
different patterns in various ranges of frequency. Its area can be 
scaled with Omega similar to omega(1/3) at low omega. The remnant 
polarization P-r shows a maximal as a function of w. At small domain 
size, the dynamic hysteresis is significantly compressed, predicting 
ferroelectricity weakening effect at small domain size.

　　Abstract: A Monte Carlo approach based on the Q-state（web of 
science上印刷错误，为e-state，已更正） Ports model is developed to 
describe and simulate the dynamic hysteresis of Potts spin lattice 
against periodic time-varying external field E. The dynamic responses 
of the hysteresis loops against frequency omega of applied field and 
domain size R are studied. It is revealed that the hysteresis loops 
for the system energy W, polarization P, and domain wall fraction Pi 
depend considerably on the frequency and domain size. The remnant 
polarization P, shows a single-peak pattern as a function of omega. 
The P - E loop exhibits thin rhomb and fat rhomb patterns at low w, 
whereas a tip-smoothed rhomb and roughly elliptical pattern is 
observed at high omega. The loop area can be scaled with Omega 
approximate to omega(1/3) at low omega. The frequency dependency of 
the dynamic hysteresis is explained in terms of a simplified 
phenomenological model. At very small domain size, the dynamic 
hysteresis is significantly compressed, predicting the polarization 
weakening effect at small domain size.

　　发现没有？文七和文八很多句子的文法完全相同（尽管仍有粉饰）。完全相
同的工作，完全相同的结论，但发表在不同的学术杂志上，这是不是典型的一稿
两投？

　　正如前文已提到的那样，同一个工作，文七的作者是Liu JM, Ong CK, Lim 
LC ，而文八变成了Liu JM, Liu ZG。文七的第一作者单位是新加坡Natl Univ 
Singapore，文八却是中国南京大学。呜呼！学术论文要不要严谨？学术成果有
没有归属？将来万一获得“X贝尔”奖，会不会引起“中新学术大战”？

　　信手一查，就发现这么多严重问题。而刘俊明正是借助这些学术泡沫发家了，
拿到了国家杰出青年基金，霍英东教育基金，长江学者特聘教授。看来，学术打
假任重而道远啊！
