J. Cent. South Univ. Technol. (2011) 18: 1502-1508 DOI: 10.1007/s11771-011-0866-4 Three-dimensional multi-constraint route planning of unmanned aerial vehicle low-altitude penetration based... Berlin Heidelberg 2011 Abstract: To address the issue of premature convergence and slow convergence rate in three-dimensional (3D) route planning of unmanned aerial vehicle (UAV) low-altitude penetration......
that, the sheets were heated at 450 ℃ for 1 h and rolled by two different rolling ways. Route A is the unidirectional rolling where the rolling direction (RD) is always the same. Route B is a special crossing.... On the contrary, there are some twins present in the route B sample of 1.38 mm. This indicates that the microstructure is hardly affected by the change of the rolling ways. 3.2 Texture evolution Fig.3 shows......
