In the chapter 5, during the optimization, the influence of search efficiency of choosing search variable is studied, and author proposes a kind of choice, which the positions of two exit points and the sagitta of the slip surface are taken as the search variable (the sagitta depends on the dynamic positions of two exit points of the slip surface), The examples show that the choice method decrease search region, improve the efficiency of searching, and has applying foreground.

Based on the data from eight seasonal oceanographic censuses in the Changjiang Estuary (28°00′-32°00′N, 122°00′-123°30′ E) in 1959 and 2002, this paper discussed temporal\|spatial distributions of Sagitta crassa and Sagitta enflata and effects of global warming on them in the Changjiang Estuary. The results show that the average abundance of S. crassa was less than 1.00 ind/m3, and its occurrence frequency was lower, had no aggregate feature during spring, summer and autumn.
