河蟹养殖无人作业船路径跟踪算法研究

河蟹养殖无人作业船能解决人工养殖成本高、效率低等问题,提高渔民收益。河蟹养殖无人作业船自动导航作业的关键是路径跟踪,传统的纯追踪算法行驶路径只包含直线作业与岸边曲线转弯作业,不能满足作业船的自主循迹（自动导航）需求。为此针对预先规划的路径,研究了改进的纯追踪算法。通过试验对该导航控制算法进行验证,结果表明,无人作业船在以50cm/s的速度行驶并转弯半径为5m时,最大路径跟踪误差可以控制在0.1m以内。     

On the status of critical theory

Critical theory, while remaining in part a scientific social theory, is not just a scientific theory. The nature and distinctiveness of its criticalness is depicted. The logical status of a rationally reconstructed Habermasian critical theory is displayed, defended from some traditional criticisms (including charges of historical idealism), and contrasted with both historical versions of critical theory and purely scientific theories. Whether the critical theory articulated and defended is Habermasian, or a more historicized critical theory, in either case it is argued that it provides a sound basis forideologiekritik against postmodernist scepticism.

Promoting understanding of chemical representations: Students' use of a visualization tool in the classroom

Many students have difficulty learning symbolic and molecular representations of chemistry. This study investigated how students developed an understanding of chemical representations with the aid of a computer‐based visualizing tool, eChem, that allowed them to build molecular models and view multiple representations simultaneously. Multiple sources of data were collected with the participation of 71 eleventh graders at a small public high school over a 6‐week period. The results of pre‐ and posttests showed that students' understanding of chemical representations improved substantially (p < .001, effect size = 2.68‐. The analysis of video recordings revealed that several features in eChem helped students construct models and translate representations. Students who were highly engaged in discussions while using eChem made referential linkages between visual and conceptual aspects of representations. This in turn may have deepened their understanding of chemical representations and concepts. The findings also suggest that computerized models can serve as a vehicle for students to generate mental images. Finally, students demonstrated their preferences of certain types of representations and did not use all types of three‐dimensional models interchangeably. © 2001 John Wiley & Sons, Inc.
