On the ship body, the parabolic curve panels are adopted to discretize the surface in order to improve the continuity and the linearly variable sources are distributed on panels. The solid boundary condition is satisfied rigidly on the curve panel.

在船體上影音先锋男人看片Av资源网，本文采用了二階拋物面單元離散船休表面5566影音先锋在线，以改善用平面單元離散時出現(xiàn)的不連續(xù)黄片免费视频高清在线观看，并在單元上布置強度呈線性分布的源匯看农村黄色视频，固面條件在曲面單元上嚴格滿足。

The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.
