In this research, the effects of centrifugal radius and mould rotation speed on microstructure in centrifugal-cast Al-Cu alloy have been investigated. The results show that, with increase of the centrifugal radius or mould rotation speed, the grain size of centrifugal-cast Al-Cu alloy decreases gradually, while the content of white phases containing the Al2Cu precipitated from α-phase, divorced eutectic and regular eutectic microstructure increases, leading to higher Cu macrosegregation. The variation level of microstructure in centrifugal-cast Al-Cu alloy at 600 rpm of mould rotation speed is greater than that at 300 rpm.

银盘上化学元素的丰度梯度对研究银河系特别是银盘的形成与演化过程有着重要的意义.丰度梯度的时空变化趋势是银河系星际介质增丰历史以及内落、外流等过程的反映,是银河系化学演化模型的重要约束.利用陈玉琴和Edvardsson等人两个样本中235颗F,G型中小质量星的金属丰度数据,结合崔辰州等人轨道计算程序得出的轨道参数,分析了银盘金属丰度梯度在空域、时域的变化.分析结果表明:薄盘内存在径向和法向丰度梯度,

文章围绕三维可视化技术中的地表模型加速绘制方法进行了分析与探讨,针对传统绘制方法中所存在的不足之处,提出了一种新的基于线性四叉树的接边处理方法。其主要思想是:在基于LoD技术的地表细节层次模型的绘制方法的基础上,结合线性四叉树在邻域搜索上的特性,就能消除绘制中易出现的“裂痕”现象。
