今天无聊查了下2010年的影响因子
发现排第二的是一个从来没听说过的杂志：ACTA CRYSTALLOGR A （IF=49.926)
这个是神马啊？我查了下他09年的IF，竟然才有2.051。。。一年的时间翻了25倍啊！
于是我激动了，本来想要本着科学的态度自己google一下那些把IF提高了25倍的大作，
结果发现google直接把我指向一位叫王超的同学的博客。看来这个工作早有人做过了。
以下就是引用啦！欢乐～
--------引用开始
这个杂志，可能以前默默无闻，但2009却因一篇文章的原因，IF直接超过Science，
nature，位居第二。
2007年IF=2.385，2008年IF=2.051，而2009年IF=49.926！
今晚，我查询了一下引用率（截止2010.9.28，22:38，被引用次数为：11914），超牛
，有图为证。
那么这篇牛作到底写了什么呢？

A short history of SHELX
G. M. Sheldrick
Abstract: An account is given of the development of the SHELX system of
computer programs from SHELX-76 to the present day. In addition to
identifying useful innovations that have come into general use through their
implementation in SHELX, a critical analysis is presented of the less-
successful features, missed opportunities and desirable improvements for
future releases of the software. An attempt is made to understand how a
program originally designed for photographic intensity data, punched cards
and computers over 10000 times slower than an average modern personal
computer has managed to survive for so long. SHELXL is the most widely used
program for small-molecule refinement and SHELXS and SHELXD are often
employed for structure solution despite the availability of objectively
superior programs. SHELXL also finds a niche for the refinement of
macromolecules against high-resolution or twinned data; SHELXPRO acts as an
interface for macromolecular applications. SHELXC, SHELXD and SHELXE are
proving useful for the experimental phasing of macromolecules, especially
because they are fast and robust and so are often employed in pipelines for
high-throughput phasing. This paper could serve as a general literature
citation when one or more of the open-source SHELX programs (and the Bruker
AXS version SHELXTL) are employed in the course of a crystal-structure
determination.
Keywords: computer programs; crystal structure determination; phasing; SHELX
; structure refinement.
我拜读了下，大致写的就是SHELX。
什么是SHELX呢？
SHELX是德国哥廷根大学的著名晶体学教授赛尔德雷克（Sheldrick, G.M.）编写的一个
共享软件，该软件在晶体学领域获得了极大的欢迎，研究晶体学的科学家们几乎人手一
份。08年的时候，赛尔德雷克教授决定在SHELX的安装协议里面增加一条，内容如下：
The following reference should be cited whenever a program beginning with
the letters "SHELX..." is used, including the Bruker SHELXTL system: G.M.
Sheldrick, "A short history of SHELX", Acta. Cryst. (2008) A64, 112-122.
（大意是说凡是提到了SHELX系列软件的文章，都应该引用“SHELX简史”这片文章）
再算算有多少人弄晶体，而今最为方便的还是SHELXTL软件包，所以几乎每篇关于晶体
的文章都会引用该文，而杂志的影响因子（IF）=其前两年发表的文章在第三年被引用
的次数/前两年发表的总文章数目，故也就不稀奇为什么一下子翻那么多倍了。
不过，ACTA CRYSTALLOGR A的水平未必真的那么高，就不多说了。
