摘要

本文讨论了放射虫骨骼结构的几何特征，即Didymocyrtis属。我们描述了骨骼结构的演变，并使用几何分析了结构。我们定义了两个比值，以量化双胞藻的几何特性，并验证了这两个比值随其系统发育进化而变化。我们还使用了D. tetrathalamus物种标本的三维骨骼数据，这些数据是通过微x射线CT获得的。在三维数据中得到的皮质壳被投影到一个球面上，我们确定了孔隙的中心。分析表明，孔隙数量约为200个，且分布不规律。我们还确定骨架的柱状部分，连接标本的内部和上部，不在一个平面上，它们的间隔也不相等。

Geometrical Properties of Skeletal Structures of Radiolarian Genus Didymocyrtis

This paper discusses the geometrical properties of a radiolarian skeletal structure, namely, that of genus Didymocyrtis . We characterized the evolution of skeletal structures and analyzed the structures using geometry. We defined two ratios in order to quantify the geometrical properties of Didymocyrtis and verified that the two ratios changed with their phylogenic evolution. We also used the 3D skeletal data of a specimen of species D. tetrathalamus , which were obtained through micro X-ray CT. The cortical shell obtained in the 3D data was projected onto a spherical surface, and we determined the centers of the pores. Our analysis revealed that the number of pores is approximately 200 and their distribution is not regular. We also determined that the column-like parts of the skeleton, which connect the inner and upper parts of the specimen, do not lie on a plane and their intervals are not equal.

期刊介绍： Image Analysis and Stereology is the official journal of the International Society for Stereology & Image Analysis. It promotes the exchange of scientific, technical, organizational and other information on the quantitative analysis of data having a geometrical structure, including stereology, differential geometry, image analysis, image processing, mathematical morphology, stochastic geometry, statistics, pattern recognition, and related topics. The fields of application are not restricted and range from biomedicine, materials sciences and physics to geology and geography.
