  • 简介:在这份报纸,我们基于间接轻路径复用学习一套全球照明算法的评价变化。这些算法通常在第一张通行证包含二张通行证,间接轻样品的一个小数字被产生并且评估,并且他们然后被很多重建样品在第二张通行证再使用。我们的分析证明重建样品的协变性在高重建率下面统治评价变化并且增加重建率不能有效地减少协变性。我们也发现协变性代表到到什么度,间接轻样品在重建期间被再使用。这分析激发我们设计启发式的接近协变性以及一个适应采样计划基于这对还原剂启发式显示的变化。我们为间接点亮在间接的轻地重建算法和排列轴的过滤算法验证我们的分析和适应采样计划。实验根据我们显示人工制品能极大地以类似的计算成本被减少的分析和表演。

  • 简介:【摘要】 《英语课程标准》指出英语学习注重语言学习的过程,强调语言学习的实践性,鼓励学生在教师的指导下,通过体验、实践、参与、探究和合作等方式发展自主学习能力。核心素养背景下拓展英语学科丰富的育人价值,实施跨学科实践活动课程,是促进新形势下人才培养模式转变,落实核心素养发展目标的重要途径。因此,笔者以译林新版六上Project2 Reuse and recycle单元为主题,尝试在小学英语课堂开展跨学科实践活动,对学生的英语教学活动进行全新的尝试。
