前言： SCI論文投稿 Cover Letter的寫作和中文投稿有很大的不同。 Cover Letter的撰寫對於新手而言不知該寫什麼，而對於老手往往又被忽視。Cover Letter重要嗎？可有可無嗎？ 本文部分內容轉自科學網，希望能對新手、老手都有所幫助：
1、 什麼是Cover Letter？
即投稿信
2、cover letter的內容主要包括那些？
應該簡述所投稿件的核心內容、主要發現和意義，擬投期刊，對稿件處理有無特殊要求等（如「not to review」 list）。另外，請附上主要作者的中文姓名、通訊地址、電話、傳真和e-mail地址。此外有的雜誌要求推薦幾位審稿人及其聯繫方式。以及誰已經閱讀過該文（當然是牛人）。
3、 如何寫cover letter？
各個雜誌的具體要求是不一樣的，在雜誌的guide for authors一般會有要求。如果沒有具體的要求，大家可按照通用要求處理。
4、常用模板：
模版一
模版二
模版三
模版四
5、 例文展示：下面例文都來自丁香園戰友，在此一併感謝。

Dear Editor,
We would like to submit the enclosed manuscript entitled "GDNF Acutely Modulates Neuronal Excitability and A-type Potassium Channels in Midbrain Dopaminergic Neurons", which we wish to be considered for publication in Nature Neuroscience.
GDNF has long been thought to be a potent neurotrophic factor for the survival of midbrain dopaminergic neurons, which are degenerated in Parkinson’s disease. In this paper, we report an unexpected, acute effect of GDNF on A-type potassium channels, leading to a potentiation of neuronal excitability, in the dopaminergic neurons in culture as well as in adult brain slices.
Further, we show that GDNF regulates the K+ channels through a mechanism that involves activation of MAP kinase. Thus, this study has revealed, for the first time, an acute modulation of ion channels by GDNF.
Our findings challenge the classic view of GDNF as a long-term survival factor for midbrain dopaminergic neurons, and suggest that the normal function of GDNF is to regulate neuronal excitability, and consequently dopamine release. These results may also have implications in the treatment of Parkinson’s disease.
Due to a direct competition and conflict of interest, we request that Drs. XXX of Harvard Univ., and YY of Yale Univ. not be considered as reviewers. With thanks for your consideration, I am
Sincerely yours,

Dear Sirs,
I am sending herewith a copy of the manuscript, which I would like to submit to SOLA, the Electronic Journal of the Meteorological Society of Japan.
The paper is entitled:
Energy Spectrum Proportional to the Squared Phase Speed of
Rossby Modes in the General Circulation of the Atmosphere
by H. L. Tanaka, Yasushi Watarai, and Takahiro Kanda.
Copy of the Abstract:
In this study, energy spectrum of the large-scale atmospheric motions is examined in the framework of the 3D normal mode decomposition.
The horizontal scale of disturbance is measured by the phase speed of a Rossby mode c. According to the analysis result for the barotropic component of the atmosphere, we obtain a characteristic energy spectrum with distinct slopes for the turbulence and wave regimes separated by the spherical Rhines speed.
In order to explain the observational finding that the energy spectrum is proportional to c^2, we put forward a hypothesis based on the criterion of Rossby wave breaking such that the local meridional gradient of potential vorticity becomes negative, dq/dy < 0, somewhere in the domain.
With a constant m describing a total mass of the atmosphere for unit area, we have shown that the barotropic energy spectrum of the general circulation E can be represented as E=mc^2.
