For developing a method to reduce the emanation coefficient of Rn in materials, emanation coefficient of Rn in geological uranous materials such as zircon, uranium-bearing ore, etc is measured. Heating is used to study the effect of heating temperature on emanation coefficient of Rn.
通过了解锆英砂、铀矿粉、石英砂铀矿粉混合物等含铀地质材料中222 Rn的析出情况，探索了降低这些材料中氡射气析出率的方法，并应用灼烧法研究了灼烧温度对上述材料中氡射气析出率的影响。

On the basis of OCM, segmentation based on curvature radium is presented in the paper, in which curvature radium is calculated using parametric-surface fitting, and detecting edge points is realized from orthogonal direction, which ensure the integrality of edge points. Since the data is organized by cross-line in OCM, a new arithmetic, Double-direction Angle Difference arithmetic, is brought forward, which can pick up edge points more quickly.
物体的表面一般由多个曲面相交组成，要建立完整的几何模型，需要对测量数据进行区域分割——区分不同曲面的数据，现有的区域分割大多是对单视图的图像式测量数据进行的，但完整的CAD模型需要联合多个视图产生，本文在上面提出的三维正交模型的基础上，提出了三种区域分割方法：第一种方法是基于曲率半径的数据分区方法，通过二次参数曲面拟合计算局部曲率半径，从正交的多个方向进行检测，保证了边点提取的完整性。

They announced the discovery of radium and polonium by fractionation of pitchblende in 1898 and later they did much to elucidate the properties of radium and its transformation products.
玛丽后来写道："圣路易医院的兜娄大夫已经研究了镭对皮肤的作用。镭在这一方面的效果是令人鼓舞的；它的作用所毁坏的部分表皮，重长起来是健全的。"镭有用处——用处大极了！2。不要勋章，要实验室
