After a manuscript has been accepted for publication, the author or his/her company or institution will be requested to pay a charge of $110 per page, for the first eight published pages, to cover part of the cost of publication. Payment will not be obligatory nor a prerequisite for publication.

日本的情况不同,发1篇电气学会Transactions的论文(8页以内)必须至少订50部reprints(9万5千日元)。
现在知道IEEE Transactions是Voluntary Page Charges,那就往IEEE投,读者也多。

Thanks again.
