致谢一般以单独成段的形式位于正文的后面，但不是论文的必要组成部分。致谢部分用来对致谢对象表达道义上的感谢，也是尊重致谢对象贡献的标志。致谢通常包括以下两方面的内容：

1.感谢个人或组织在研究工作或论文写作中的帮助，其中包括提供仪器、设备或相关实验材料，给予技术、信息、物质或经费等方面的帮助，协助实验工作，提供有益的启发、建议、指导、审阅，承担某些辅助性工作等。可以使用诸如“Thanks are due to J.Jones for assistance with the experiments and to R.Smith for valuable discussion.”的表达。

2.感谢论文研究工作的资助项目（或基金项目），必要时附资助项目、合同书等的编号（资助项目的内容也可以放在论文首页的脚注中）。

总体而言，致谢一定要简洁。常见的表达方式有：

The authors thank...

We are deeply indebted to...

We are grateful to...(www.daowen.com)

The authors wish to acknowledge...

一个简单的致谢可以如下：

We thank Dr.A.B，Chen for her comments on the manuscript and Mr.X.Y.Zataki for his technical assistance.This work was supported by U.S.Public health Service Grant Gm-10880-32.

又如：
