◇◇新语丝(www.xys.org)(xys.dxiong.com)(xys.3322.org)(xys.xlogit.com)◇◇ 神迹：石峰博士五年至少发表51篇论文获批19项专利 作者：科学求真 舟子： 无论多忙，每日必读新语丝。我辈同仁对先生的钦佩自不必多说，久读先生 文章之后，竟然生起出手支持舟子之想法． 我于2002年底毕业于美国某大学，化学专业Ph.D. 现博士后的干活。7年里 勤奋工作，不才得很，至今才发表了6篇第一作者3篇第二作者共9篇论文。稍感 欣慰的是，我的教授却对我褒奖有加。 今天（１２月９号）在新雨丝上读到Bidendate写的＜兰州化物所石峰博士， 请你回答！＞一文，不禁惊讶于石峰博士的高产．惊异之下认真核实，发现石峰 博士在2000年至2005年，至少发表了51篇论文，申报并获批了十九项专利．真乃 神人！各位请看，详细情况附后。 我认真阅读了Bidendate反映的情况，基于我的专业知识，我完全同意他的 分析。石峰博士所发的文章，粗制滥造，治学极不严谨，给人感觉是为了发文章 而发文章，不是一个严肃科学家的态度。现在我就他最近发表在JACS（J. Am. Chem. Soc.以下同）上的文章，做如下具体评论。欢迎同行指正。 一，石文要旨。 石峰博士发文的套路，与不久前被揭露的中国科技大学陈乾旺教授诸公用高 压锅煮出金刚石的妙想一脉相承——他们声称在解决当今重大科学难题上有重大 突破，堪称石破天惊！陈教授用不值钱的原料——石墨，在自制的高压锅里，煮 出了价格昂贵的金刚石！其主要错误在于：他们对产品的检验不严谨，但好歹还 算是有鉴定；而石峰博士则技高一筹，他们试验用的两种主要原料之一，是人类 欲尽力摆脱的废物——二氧化碳，其反应可简化为不值钱的原料（R）+ 二氧化 碳，生成较值钱的产物（P）。反应器也是自制的炉子，外加高温高压。较陈乾 旺更加恶劣的是，石峰等只是简单声称：他们得到了预期的产物，以及产率、转 化率如何之好云云，但是竟然没有任何有关产物鉴定的具体数据与图谱。红外和 核磁，是常规的必须做的产品定性分析，这个分析回答产物是什么的问题。他们 给出了GC（气相色谱）产率，但没有一张色谱图（色谱图中能看出有多少物种及 相对含量）。上述三种图谱，居然一张都没有出示，也没有文字描述，就敢断然 声称那么重大的发现——他们可以变废为宝，硬是把二氧化碳这种温室气体变为 有价值的化学原料！ 二，石文如何能够在JACS上发表。 大家一定会问既然该文存在如此重大问题，为何能通过评审？ 主要原因有二。其一，评审者相信作者，如前面指出的，合成中产物的鉴定， 是常规操作，评审者自动认为研究者会认真去做，否则该作者就不应该从事科学 研究。其二，该文是一篇两页的简短通讯，JACS的通讯文章主要看重新颖 （novelty）和广泛重要性（general interest）。该文无疑是满足这两项标准 的。然而科学是求真，你要是成心不求真，毫无防范的义务评审者又奈你何！ 三，石文有存心欺骗之嫌疑。 如Bidendate所指出的，石峰博士等在supporting materials中说：＂the procedure for preparation of the catalysts had great effect on the catalytic activity and some unclear factors usually affected the catalytic activity severely.＂ 很多时候评审者是不去看supporting materials的，因为它只是用来做辅助说明，重要的关键的内容，应该写在正文 里．试想：如果石峰博士在正文里说＂the procedure for preparation of the catalysts had great effect on the catalytic activity and some unclear factors usually affected the catalytic activity severely＂，会有什么样 的结果？ 以上是我考察的结果． 石峰博士这种行为对中国社会资源的浪费，对社会道德的副作用，不用我说 大家都明白，单说说对咱们这些在美国从事科学研究的中国人的影响，说说对化 学界有影响的杂志的伤害，就够说到天亮，气得人喝茶都没味道．简单地说，有 如下几点： 一，他这样的＂高产＂，对认真搞科学研究的人是不公平的，你兢兢业业地 做试验，发文章慎之又慎，他那里鬼画符一样地转眼发了一大堆沽名钓誉的文章． 这不是公平竞争． 二，这样不负责任地毁坏中国科学工作者的名声，日子久了，纸包不住火， 总要露馅儿，将来人家遇到中国人寄来的文章，就先怀疑是不是真的，对那些严 谨治学的中国科学家是不公平的． 三，大家都是做化学的，都知道JACS的分量，但是如果这样的文章多了，这 本有着一百二十六年辉煌历史的杂志，就会因此名声受损，我不愿意看到这本杂 志的声誉被玷污． 对于这件事，我觉得石峰博士有义务回答我的质疑，并出具原始的有关产物 的红外图谱，色谱图谱，核磁图谱．真理应该经得住质疑． 方舟子先生的打假事业，于国家有利，于社会有利，于我们每个有良心的科 学工作者有利，我深表敬意，并以实际行动予以支持． 附录：石峰博士２０００年到２００５年＂成果＂一览 Publications: Year 2000-2005 1.
