如何进一步办好本刊,使其更好地为广大读者服务,是作者和编者所共同关心的问题,也是义不容辞的责任。为此,我们组织了这次笔谈。由于篇幅的限制,来稿依收到的时间为序分期发表,请作者鉴谅。 How to further improve the publication and make it serve the readers well is a matter of common concern to authors and editors. It is also an unshirkable responsibility. For this reason, we organized this writing. Due to space limitations, the manuscript published in accordance with the order of the time published, please author forgive me.
