The manuscript should not be submitted to more than one journal for simultaneous consideration.
The manuscript should not have been published previously (in part or in full), unless the new work concerns an expansion of previous work (please be transparent on the re-use of any materials to avoid any doubt of text-recycling (“self-plagiarism”)).
A single study should not be split up into several parts to increase the quantity of submissions, then submitted to various journals or to one journal over time (eg “salami-publishing”).
No data should be fabricated or manipulated (including images) in order to support conclusions.
No data, text, or theories by others should be presented as if they were the authors' own (“plagiarism”). Proper acknowledgements to other works must be given (this includes any materials that are directly cited, summarized and/or paraphrased). Quotation marks are used for direct citation of materials, and permission must be secured for material that is copyrighted.
Important note: the journal may use software to screen for plagiarism.
All co-authors and responsible authorities where the work was carried out must give their consent to publish before the work is submitted.
Authors whose names appear on the submitted paper have contributed sufficiently to the work and therefore share collective responsibility and accountability for the results.
In addition:
Changes in authorship or in the order of the authors' names are not accepted once the manuscript has been accepted. Requests to add or delete authors at the revision stage or after publication is a serious matter and may be considered only after receiving written approval from all authors with a detailed explanation about the role/deletion of the new/deleted author. The decision to accept or decline the change rests with the Chief Editor of the journal.
Upon request, authors should be prepared to send relevant documentation or data to verify the validity of the results. This could be in the form of raw data, samples, records, etc.
If there is any suspicion of misconduct, our board will carry out an investigation following the COPE guidelines. If the allegation seems to raise valid concerns, the accused author will be contacted and given an opportunity to address the issue. If misconduct has been proven, it may result in the implementation of certain measures, for instance:
If the article is still under consideration, it may be rejected and returned to the author(s).
If the article has already been published online, depending on the nature and severity of the infraction, either an erratum will be placed with the article or, in severe cases, the article will be completely retracted. The reason must be given in the published erratum or retraction note.
The author(s)' institution may be informed for the misconduct.
Statement of Human and Animal Rights
When reporting studies that involve human participants, authors should include a statement confirming that the studies have been approved by the appropriate institutional and/or national research ethics committee and have been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments, or other comparable ethical standards.
If doubts exist about whether or not the research was conducted in accordance with the 1964 Helsinki Declaration or other comparable standards, the authors must explain the reasons for their approach, and demonstrate that a qualified ethics committee or institutional review board has explicitly approved of the doubtful aspects of the study.
The following statements should be included in the text before the References section:
Ethical approval: “All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.”
The welfare of animals used for research must be respected. When reporting experiments on animals, authors should indicate whether the institutional and/or national guidelines for the care and use of animals were followed.

Text
A paper should begin with a brief introduction of the significance of the author's research. Nomenclature, signal, and abbreviation should be defined at their initial appearance. All the figures and tables should be numbered in numerical order.
Introduction : Being the most important part of an article, the introduction introduces the relevant research background and the progress in 2 or 3 years, with references cited in numerical order, then presents the problem to be solved in this article, and finally briefly describes the method adopted in this work. Before the end, the aim of the research should be mentioned. Subtitle is forbidden in this part, and introduction of the article structure is considered unnecessary.
Materials and method : This part introduces the materials, method and experimental procedure of the author's work, so as to allow others to repeat the work published based on this clear description.
Discussion and conclusions : Conclusions should be derived from the observation and experimental results, and comparison with other relevant results is considered helpful to further proving the results. Repeated data should be avoided, and conclusions and suggestions are required to be clearly expressed. New hypotheses and recommendations may be proposed when warranted.
Figures and tables : Figures and tables should be numerically numbered, inserted in the text, and cited in order within the text. The figures should have resolution not lower than 600 dpi and clear lines of 5 px, with signals and letters in Times New Roman at 8 pt. A space should always be maintained between the variable and the unit.
Equations : An equation is numerically numbered (Arabic numeral), and has the number put on its right side.
Acknowledgements : The author expresses his/her thanks to the people helping with this work, and acknowledges the valuable suggestions from the peer reviewers.
Financial support : Financial support appears on the bottom of the title page, with grant number(s) following. The full title of each fund is required. For example: National Natural Science Foundation of China; National High-Tech Research & Development Program of China; National Basic Research Program of China.
References
References : Reference citation is regarded as an important indicator of the paper quality. If the relevant references, especially the results published in 2 to 3 years are not cited in the paper, or most citations are from the author's publications, the editor will consider this paper unattractive. References should be numerically numbered and cited in order within the text, with the numbers expressed in square brackets. The author should carefully check the author names, article title, journal title, year, volume and issue number of references, and create the listing according to the format of Sci China Tech Sci .
Reference format
1. For an author's name, full spelling of family name appears before abbreviation of given name, with a spacing in the middle.
2. If there are more than 3 authors, the first 3 names are followed by et al.
3. The article title should be identified by an initial capital letter with the remainder of the title in lower case.
4. For correct abbreviations of journal titles, refer to ISO, eg, Chin Sci Bull for Chinese Science Bulletin , Sci China Life Sci for Science China Life Sciences.
5. For books and proceedings, the initial letter is capitalized for all the notional words and for function words with more than 4 letters.
6. Do not forget to list the editor names of the proceedings, the publisher, the publishing address, and the beginning and terminating pages.
7. Accepted but unpublished papers should be followed by “in press”.
8. Websites or homepages cannot be cited as references.

Conflict of Interest
Disclosure of potential conflict of interests
Authors must disclose all relationships or interests that could influence or bias the work. Although an author may not feel there are conflicts, disclosure of relationships and interests affords a more transparent process, leading to an accurate and objective assessment of the work. Awareness of real or perceived conflicts of interests is a perspective to which the readers are entitled and is not meant to imply that a financial relationship with an organization that sponsored the research or compensation for consultancy work is inappropriate. Examples of potential conflicts of interests that are directly or indirectly related to the research may include but are not limited to the following:
· Research grants from funding agencies (please give the research funder and the grant number)
· Honoraria for speaking at symposia
· Financial support for attending symposia
· Financial support for educational programs
· Employment or consultation
· Support from a project sponsor
· Position on advisory board or board of directors or other type of management relationships
· Multiple affiliations
· Financial relationships, for example equity ownership or investment interest
· Intellectual property rights (eg patents, copyrights and royalties from such rights)
· Holdings of spouse and/or children that may have financial interest in the work
In addition, interests that go beyond financial interests and compensation (non-financial interests) that may be important to readers should be disclosed. These may include but are not limited to personal relationships or competing interests directly or indirectly tied to this research, or professional interests or personal beliefs that may influence your research.
The corresponding author will include a summary statement in the text of the manuscript in a separate section before the reference list.
