论文署名作者越多，论文质量越低

质量决定水平。

然而流行时髦（可能不是H1N1流行感冒）的做法是标记（评价）论文的水平，而不是标记（评价）论文的质量。

什么是水平？

最省力的做法，也是最盲目的做法就是根据刊物来评价论文的水平，这就是拜刊物忽悠水平教派，这个科学教派是非常强大的。

 

根据论文本身来评估论文的质量，这是正本清源的做法。

评估论文质量，究竟如何来操作，这是个技术层面的问题，真正想搞也不难。

 

上次本博主评估了余瑞璜先生（三个作者）发表在《中国科学》的文章，存在严重问题，因为把Nd2Fe14B的键络数据搞错了，从而影响到以后真正的EET计算，究竟他们三个作者是如何分工的，这俺就不知道了。但是，那文章署名了3个人，白纸黑字，这是事实。

本文评估余瑞璜先生独自发表的一篇文章，白纸黑字，署名了惟一的作者，就是余瑞璜先生自己，如下所示。

 

        两篇文章，一个发表在《中国科学》，一个发表在大学学报。如果按照“水评论”，是前者水平高；如果按照“质量论”，是后者质量高，本博主要给出证据。

Al12Mg17结构属于空间群217号，一个晶胞里有58个原子。

余瑞璜先生给出的Al12Mg17晶体的键络参数如下：

 

余瑞璜先生最大键长取值到d=4.690。

如果截取到d=4.690，晶体空间共有15条键，余先生的结果也是15条。

如果把余先生的结果按照红色数字编号（键长从小到大），和俺用《点群/空间群操作系统》计算的结果完全一样，“完全一样”包含三个指标：

1）  成键的原子种类，例如，24g-Al---24g-Al，就是DAlAl；

2）  键长，误差在0.005左右。

3）  配位数，完全一样。

余瑞璜先生自己30年前干的工作，非常漂亮！

结合实际的数据，下面详细地解说余瑞璜先生工作的妙处！

第6条键的数据显示，空间配位数和配对配位数是有差别的，余瑞璜先生的处理手法和Herbst J F（1991 Rev. Mod. Phys. 63 822）的是一样的。

 

需要提醒的是，等同键数 Ia＝I1×I2×I3，其中

I1从空间群占位结构式取值；

I2从空间配位数（Z）取值；

I3的值规定为：如果是空间群意义上的同种原子成键，I3＝1；

              如果是空间群意义上的不同种原子成键，I3＝2。

（实际上，应该是按照点群对称性来分类，不过立方晶体不显示区别）

空间群占位表达式为：2a(Mg)8c(Mg)24g(Mg)24g(Al)

约化之后为：1(2a-Mg)4(4c-Mg)12(24g-Mg)12(24g-Al):

I1将从蓝颜色的数字中取值。
