Before I publish VORTEX, however, I've taken some time away from the Spin books to write an unrelated novel set in 22nd century America, to be called "Julian Comstock," based on the current Hugo-nominated novella Julian: A Christmas Story .

在《漩涡》出版之前，我会暂时离开「时间回旋」系列，拨出时间撰写一本暂时定名为《朱利安康斯多克》的小说，这本书设定在廿二世纪的美国，从入围 2007 年雨果奖最佳中篇的作品──《朱利安──一则耶诞故事》（2006，由 PS Publishing 出版）扩充改写而成。

By using the swirling strength method,the vortex structures excluded the effect of shear were shown clearly,and were concentrated in the coniform area of the central mixing flow field.With increasing Reynolds number,swirling strength increased and the coniform area became narrow.
