Attention to Your Abstracts and References

Since on-line search databases typically contain only abstracts，it is vital to write an efficient abstract with a fully self-contained，capsule description of the paper.An abstract should be written in a subjective tone and simple present tense.

The literature in references should have been published before.The references must be numbered consecutively in the order of appearance in the text and should be listed at the end of the text material.Author′s name in references must be listed as″Last name First name initials″.If there are more than four authors，only the first three are required and the rest is replaced by″，et al.″.
