Tsinghua Science and Technology (Tsinghua Sci Technol), a comprehensive academic journal sponsored by Tsinghua University, is published bimonthly. This journal aims at presenting the up-to-date scientific achievements with high creativity and great significance in various engineering fields and in mathematical sciences, life sciences, chemistry, physics, etc. Contributions within the above scope all over the world are welcome. Tsinghua Sci Technol is indexed by Engineering index (Ei, USA), Chemical Abstracts (CA, USA), INSPEC, P* (Russia), SA, Cambridge Abstract and other abstracting indexes.
Manuscripts are selected for publication according to the editorial assessment of their suitability and evaluation from independent reviewers. Papers are usually sent to two or more reviewers including one reviewer out of China. Editorial staff will edit accepted papers to improve accuracy and clarity and shorten, if necessary.
It is a condition of publication that manuscripts submitted to this journal have not been published and will not be simultaneously submitted or published elsewhere.

Manuscript preparation
Manuscript should be in English and typed on only one side of A4 paper with double space. In addition, a manuscript disk (based on Word or LaTex) that contains the material to be considered for publication and three copies of the full-length paper are to be sent to: Editorial Board of Journal of Tsinghua University, Wenxilou Building, No. 100, Tsinghua University, Beijing 100084, China. The electronic manuscript can also be sent to the editorial board by E-mail: journal@mail.tsinghua.edu.cn.

Title and By-line
The title should be descriptive, not full sentences. Name, affiliation (institution) of the authors, city, zip code, country, E-mail address and telephone number of the author(s) should be listed.

Abstract and Key words
The abstract of about 100-150 words must accompany each article on page one. It should be a concise summary of the aims, methods, results, and conclusions and/or other significant items in the paper. Together with the title, it must be adequate as an index to all the subjects treated in the paper, and will be used as a base for indexing. Avoid displayed mathematical expressions. Define all nonstandard symbols and abbreviations. Do not use footnote indicators. If a reference must be made, include it in square brackets. Summarize the experimental or theoretical results, the conclusions, and/or other significant items in the paper. If space permits, include any important new quantitative data. Summarized results should be exact, direct, and specific. The key words should include 3-8 pieces of words or phrases to serve as guidelines for indexing.

Text
The text should contain an Introduction that puts the paper into perspective for readers, and should also contain Methods, Results, Discussion and Conclusions. The SI system should be used for units of measure throughout the text. Each Equation or Formula in the article should be numbered in the order with Arabic numerals placed on the right-hand margin.
Each caption should be written as a single brief paragraph without indentation. Figures and tables should be consecutively numbered with Arabic numerals. Tables should be drawn with three horizontal lines, at the top and bottom of the table and between the column headings and the table body.
Good quality figures have the following characteristics. They should be produced with a good quality laser printer and have lines, letters, numbers and symbols of uniform strength and contrast. Figures (except photographs) are often reduced to 7 cm × 7 cm. The final thickness of a line in a figure usually lies within the range 0.15-0.20 mm. When preparing the figures, authors should pay attention to the widths of lines and similar details, as some (e.g. dotted or thin lines) may disappear after reduction. Particular attention should be paid to line strengths in graphics prepared in vector formats.

Mathematical material
The text should make clear distinctions between physical variables, mathematical symbols, units of measurement, abbreviations, chemical formulas, etc. Authors should use italic and boldface to identify physical or mathematical variables. Variables are to be set in normal italic, and vectors, tensors, and matrices in boldface.

Acknowledgements
Individuals, affiliation, or other to be concerned who were of direct help in the work should be acknowledged by a brief statement.

References
Only essential references (formally published journals, articles, monographs, dissertations, reports, proceedings, standards, patents, and/or electronic publications) cited in the text can be listed and must be numbered consecutively by Arabic numerals, which should be listed in the same order as cited in the text. There should be at least ten references. Periodicals should be referred to in the following order: name of author(s), title of paper, name of periodical, year, Vol. (No.): page number. Books should be referred to in the following order: name of author(s), title of book. city: publishing house, year of publication. The reference published in Chinese should be translated into English and noted by "(in Chinese)".
