1、 什么是cover letter？
指的是投稿信

2、cover letter的内容主要包括那些？
应该简述所投稿件的核心内容、主要发现和意义，拟投期刊，对稿件处理有无特殊要求等（如“not to review” list）。另外，请附上主要作者的中文姓名、通讯地址、电话、传真和e-mail地址。此外有的杂志要求推荐几位审稿人及其联系方式。以及谁已经阅读过该文（当然是牛人）。
我投的那个杂志是要求说明你论文研究的意义，以及与这个杂志的相关性，另外还有的可能要写明你没有一搞多投等。此外临床实验要求写明符合伦理学要求。

3、 如何写cover letter？
各个杂志的具体要求是不一样的，在杂志的guide for authors一般会有要求。如果没有具体的要求，大家可按照通用要求处理。

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.
