数学家哈尔莫斯的自传 “I want to be a mathematician”，较早的有马元德等人的中文翻译《我要作数学家》，沈永欢翻译的第二部分，译者还有胡作玄和赵慧琪。其中的一个小节名 Writing for a living，沈先生将其译为“著书为稻粱谋”，最近另有张十铭新的译本，译为“著书谋生”。

我喜欢这个“著书为稻粱谋”，当然两者都好，标题借鉴于此。

是的，Doing research for a living，科研为稻粱谋，做研究就是为了谋生。

有高尚者如数学家所言：数学家工作是为了得到少许同事的吝啬钦佩。

但是在下不才，做研究就是为了混口饭吃。赶上了好时代，“多收了三五斗”，那就是下面所有期刊论文的发表。

猜测有人喜欢 low profile 低调，未去打扰征求许可，其他作者姓名略，本人要么是第一作者，要么是唯一作者。前两篇可自由下载，“推导内容”依稀可见，为此有责，其他时间久远，隐隐约约了。

其中的第二篇文章，如果世界是平的 flat 可以像北大韦神的工作那样，写入教科书，至少是留个旁注：那个天才告诉你“霍曼转移”最优。

另有学位论文留存

澳洲新南威尔士大学博士论文，Finite Horizon Robust State Estimation for Uncertain Finite-Alphabet Hidden Markov Models，2004。http://handle.unsw.edu.au/1959.4/38664 

哈工大博士论文，一般二自由度控制系统分析与Wiener-Hopf优化设计，1996。

哈船院硕士论文，自适应分割算法及其在异步电机参数辨识中的应用，1991。

澳洲博士论文里面，有一个刻画条件相对熵的公式很有趣，被两个美国人博士论文使用。

文章少之又少，发表越来越难，除了那些“卵翼之下”。

借用一下曾经很火的一句物理学“流言”，少即是多，less is more，不敢说每一篇都是经典，可以说篇篇是精髓，是的，一片山河，一片血，那精髓来自于血的代价，发表得少，活得才能久远，这过程成就了一个“成熟”的我，不是一般地急，“一万年太久，只争朝夕”，哈哈。

时下正办理退休，彻彻底底隐于市了，同时为长远之计修理牙齿，感谢医生不为稻粱谋，为患者健康先，时而高兴时而痛苦，加上韦神之事，有所感怀，同时检索 "Li Xie" 者众，“鱼目混珠”，清者自清，写下此文，权作鸿爪留泥。

看，我家猫咪小花留下的爪印
