| Communications in Theoretical Physics is an international journal reporting novel theoretical results in all fields of theoretical physics, published monthly by the Chinese Physical Society through the Institute of Theoretical Physics , the Chinese Academy of Sciences. Articles in this journal are abstracted/indexed in Science Citation Index (SCI), Current Contents (CC), Science Abstracts (SA), Chemical Abstracts (CA), Mathematical Review (MR) and P Ж . Contributions all over the world are most welcome.
A submission to Communications in Theoretical Physics must be the original work of the author(s) and must not be published elsewhere or under consideration for another publication in a similar form. Manuscript should be submitted in duplicate to the following address:

Communications in Theoretical Physics also encourages the electronic submission of papers by e-mail to email@example.com without the need to send a hard copy. The text of the article can be prepared using Microsoft Word or any common variant Tex (including Plain TeX, LaTeX, REVTeX, AMSTeX, etc. Figures should be submitted as separate files, preferably in PS (PostScript), EPS (Encapsulated PostScript) or TIFF formats. Please include your E-mail address, phone and fax numbers on the first page of the manuscript.
All manuscripts should be written in English. Manuscripts should be neatly typed double spaced on only one side of good white paper (of size 21 cm x 26 cm) with letters not smaller than 10 pt and ample margins (not less than 25 mm) on all sides. The items included in the manuscript should be arranged in the following manner:
1) title of the article;
3) author's affiliation(s);
4) abstract in English (for Chinese authors also in Chinese), limited to about 200 words;
5) PACS numbers (T he principal index code should be placed first );
6) keywords (no more than 4 sets);
7) main text;
8) acknowledgements (The supporting organizations with contract numbers should be written as a
footnote on page 1);
9) Appendices (if necessary);
11) captions of eventual figures and tables.
A complete list of the PACS numbers (Physics and Astronomy Classification Scheme, developed by the American Institute of Physics) is accessible on line by http at www.aip.org/pacs/pacs.html .
Corresponding author : The name, complete postal address, telephone and fax numbers and e-mail address of the corresponding author should be given on the first page of the manuscript.
Mathematical material : Numbered f ormula should be indicated by a serial number in parentheses placed on the right-hand side of the paper. The text should make clear distinctions between physical variables, mathematical symbols, units of measurement, abbreviations, chemical formulas, etc. Letters denoting variables in formulas are normally printed in italics, but units of measurement, abbreviations, chemical formulas and log-like functions such as sin, log, exp, etc. are printed in ordinary typeface.
Figures and Tables should be collected on separate sheets at the end of the manuscript, if relevant, a detailed caption should be provided for each of the figures and tables. Number figures and tables with Arabic numerals in order of appearance in the text. When preparing figures, the authors should pay particular attention to the widths of lines and curves, and sizes of some other symbols appeared in the figures, in order to avoid some of them (for example, dotted lines, dashed lines, thin lines, etc.) may disappear after reduction due to improper widths and sizes are used when drawing the figures. Figures with width less than 7.5 cm (half the width of the printed page of the journal) are most preferable. If not necessary, large figures should be avoided.
References : References should be numbered with Arabic numerals consecutively within square brackets in the text and listed at the end of the article in order of citation. A journal reference should comprise author name(s), APS (American Physical Society) abbreviated name of the journal, volume number (in boldface), year of publication, and the number of the first page, e.g.,
 J. Ellis, K. Enqvist, D.V. Nanopoulos, and F. Zwirner, Nucl. Phys. B276 (1986) 14.
 E. Witten , Nucl. Phys. B258 (1985) 75; A.M. Polyakov, Phys. Lett. B103 (1981) 207, 211.
A book reference should comprise author name(s), full title of the book (in italic), editor(s), publisher, place of publication, year of publication, inclusive page number(s), e.g.,
 K.G. Wilson, Recent Developments in Gauge Theories , ed. G. 't Hooft, et al ., Plenum Press, New York (1980), p.28.
All manuscripts will be sent to referees. A manuscript can be sent to referees only when it meets the requirements as mentioned above; otherwise, it will be returned to the author for modification. If an article is accepted for publication in the journal, the author(s) will be informed. An electronic version of the manuscript will be requested after acceptance of the paper, but floppy disks will not be returned to the author. If the manuscript cannot be accepted, the editor will inform the author(s).
Proofs: The corresponding author will receive a copy of page proofs for final reading and checking after the typesetting of the article is completed by the publisher before publication. The corrected proofs are requested to return to the publisher without delay. In those cases where proofs are not returned within a reasonable period of time (more than three months), the publisher will read the proofs and publish the article without author's comments.
Offprints and page charges : No page charges are requested to authors and their institutions. 30 offprints of each article will be provided free of charge. Additional offprints can be ordered.
