Figures should be as few and concise as possible.Only reasonable,easily understandable and correctly designed figures will be accepted.Do not use a figure if language alone is enough to explain.Table of three-lined (top line,column line and bottom line)is acceptable,but boundary line can be drawn above bottom line if a portrait sum is needed.The results of statistical data analysis,such as t or P,can be included in a table,with or without notes below the bottom line of the table.Line diagrams should fulfill the following requirements:5∶7 ratio between height and width,and suitable size of 12.5 cm×8.5 cm.The statistical figures should be presented in accordance with the data.Type figures in Word format in additional sheets.One figure and one table could be identified as Figure 1 and Table 1,but for multiple figures and tables,they should be numbered in Arabic numerals in the order in which they are presented in the text.

Titles and legends of the tables and photographs should be clearly typed on separate papers consecutively in Chinese and English simultaneously.Photographs should have the suitable size around 12.5 cm×17.8 cm,identified with photograph number and arrows on the back to indicate the top side of the figures.

Discussion should be focused on new discoveries and conclusions and standpoints extracted from the study,closely surrounding the results from the study,rather than repeating the contents of the results.In the discussion,authors should purposefully compare their findings with and analyze the results cited in the previously published literature,rather than just review the literature.Conclusions should be based on reliable evidences,not guesswork nor conjecture.

Abbreviated terms:Abbreviated terms should not be used in title.When used in text,the full term should be presented at the first time it occurs which is followed by abbreviation and/or English term and abbreviation in bracket.
