钢琴作品在茶馆背景音乐中的运用

随着当前大众饮茶诉求不断理性、完善,如今茶馆被赋予了更多功能价值,除了基础的饮茶诉求外,同时也是文化传播与传承的重要载体。对于茶馆来说,选择合适的钢琴作品,充分发挥钢琴作品的艺术价值和文化思维,从而实现茶馆氛围的合理营造。本文拟从茶馆的功能价值与文化特色分析入手,通过对钢琴作品的艺术特点进行分析,结合钢琴作品在茶馆背景音乐艺术中具体应用的可行性理解,从而探究茶馆背景音乐艺术中钢琴作品的具体运用机制。

高中思想政治课多媒体视频案例筛选的探究

多媒体视频案例的筛选要紧扣教学的主题,紧跟时代步伐,反映时事特征;要典型,要寓教寓乐;要紧紧围绕学生的生活情景,用学生身边的、感受最深的、最贴切的案例来创设教学情境,从而实现教学效益的最大化。

高中数学课堂教学预设与生成的教学实例与反思

＂预设＂与＂生成＂这对相对的概念随着课程改革的进一步深入已不断融入我们的教学实践中。教师在课堂上处理好＂预设＂与＂生成＂的关系,既可以引导学生主动探究解决问题,也可以激发学生学习数学的兴趣。

Simulation of the screening process on a circularly vibrating screen using 3D-DEM

A numerical study of the motion particulates follow along a circularly vibrating screen deck was done using the three dimensional Discrete Element Method (DEM). The motion of the particles was analyzed. The effects of vibration amplitude, throwing index, and screen deck inclination angle on the screening process are discussed. The results show that the average velocity of the particles increases along the lon- gitudinal direction of the deck. The screening efficiency is highest when the vibration amplitude, throw- ing index, and screen deck inclination angle are 3-3.5 mm, 2.7 and 15°, respectively. This work is helpful for developing a deep understanding of particle motion and for optimizing screen separator designs.
