项目摘要

In the present research, I have been construction a radiolarian image data base management and analysis system connection personal computer, image scanner, image analysis software, campus LAN, Nagoya University Computation Center (NUCC),Electric filing system and Nagoya University Furukawa Museum, although it is beyond the scope of this research in the initial stage. I could not get important results on phylogenic evolution of Radiolaria because of lack of time. Following problems, however, were examined in analyzing the microfossil image data.1.Number of the individual and species of microfossils is so huge that a large memory is needed to store the image data. In this study, I have used a personal computer linked with the computer in the NUCC through the campus LAN. The format of the image data must be same or exchangeable between the computers.2.The image data convertible into the numerical data such as diameter of shell, diameter and length of spine, etc., can be treated by statistical analysis method, while the image data morphology and arrangement of pores, costae and ridges on shell are difficult to convert into numerical data, and "human eyes" are more effective than comparison by computer.By using this system, radiolarian biostratigraphic studies have been performed in the Circum-Pacific orogenic belt (Sikhote-Alin), Alps-Himalaya orogenic belt (Pakistan) and their connection area (Indonesia). The results are described in the papers listed on the back side.

在本研究中，我已经建立了一个放射虫图像数据库管理和分析系统连接个人计算机，图像扫描仪，图像分析软件，校园局域网，名古屋大学计算中心（NUCC），电子文件系统和名古屋大学古川博物馆，虽然它超出了本研究的范围在初始阶段。由于时间关系，未能在放射虫的生殖进化方面取得重要成果。然而，在分析微体化石图像数据时，发现了以下问题：1.微体化石个体和种的数量非常庞大，需要大量的内存来存储图像数据。在本研究中，我使用了一台个人计算机通过校园局域网与NUCC的计算机相连。2.图像数据可转换为壳体直径、脊柱直径、脊柱长度等数值数据，图像数据的形态和贝壳上的孔隙、肋、脊的排列难以转化为数值数据，“人眼”比对比计算机比对更有效，利用该系统对环太平洋造山带的放射虫生物地层进行了研究（锡霍特-阿林）、阿尔卑斯-喜马拉雅造山带（巴基斯坦）及其连接区（印度尼西亚）。研究结果见背面列出的论文。
