　　错误的“科研成果”也能获奖
　　——看2009年度高等学校科学研究优秀成果奖（科学技术）授奖项目公告

　　作者：席交达

　　在教育部最近公布的《2009年度高等学校科学研究优秀成果奖（科学技术）
授奖项目公告》中，西安电子科技大学李志武等人的“基于Petri网基本信标理
论的自动制造系统死锁控制研究”项目获得自然科学奖。

　　而就在不久前，有人在国际杂志上专门写Comment指出他们的结果是错误的，

　　Comment on "On Siphon Computation for Deadlock Control in a Class 
of Petri Nets"

　　Huixia Liu; Keyi Xing; Song Gao

　　Abstract:

　　It was claimed recently in the paper by Li and Zhou that ldquoa 
polynomial time algorithm for finding the set of elementary siphons in 
S3PRs is proposed, which avoids complete siphon enumerationrdquo.
　　However, this is incorrect because Proposition 1 and Corollary 6 
of the aforementioned paper, which lead to the claim, are both 
incorrect. In this correspondence paper, Proposition 1 and Corollary 6 
are disproved.
　　As a consequence, some claims of the aforesaid paper are denied. 
Two examples are presented to disprove some claims of the previously 
mentioned paper.
