F How will Rowena's kinetic energy at 9.0 s compare with her kinetic energy at 5.0 s Explain your reasoning.

f请比较Rowena在5.0 s和9.0 s时动能的大小，并作出解释。

The results show that, during the period of collision between the sand grain and the sand bed, the lost kinetic energy is more than half of the total energy. Moreover, because the percentage of collision angles with more than 0° is up to 70％, the vertical speed of sand increases even if the kinetic energy decreases, which ensures that the sand particles can receive more energy from the air to keep on the saltation movement.

实验结果表明，沙粒与沙床碰撞过程中损失的动能超过总能量的一半，且由于碰撞平面角大于0°的比例达到70％，即使沙粒在碰撞过程中能量有所损失，沙粒与沙床碰撞后垂直分速度增加的现象仍比较普遍，使得沙粒在与气流相互作用的过程中获取更多的能量，从而为沙粒的持续跃移提供了保证。

Wave power first attracted interest in the 1970s, when Stephen Salter of the University of Edinburgh devised a device that converted the motion of waves into electricity.

对海浪能的兴趣始于上世纪七十年代，当时英国爱丁堡大学的斯蒂芬·沙特教授设计了一个能够将海浪的动能转变为电能的装置。

The movie is as heavy and realistic as Spielberg's Oscar-winning Schindler's List , but it's more kinetic.

这部电影是沉重和现实的斯皮尔伯格的奥斯卡获奖辛德勒的名单，但它更动能。

The second includes part of the first and their scission is thereafter marked by the break between signifier and signified.

这个阶段是自我形象的设立，阉割，符号动能的设立，这个阶段是「大写他者之处」的设立，是所有表义与语言之起点（102）。

Hydrogen atom is injected into closed carbon nanotube through the sidewall of the tube with an initial incident energy.
