1) Polarimetric Observation is important and key to reveal the magnetic structure in external galaxies. In order to conduct systematic polarimetric observation of galaxies for that purpose, we selected 71 galaxies from UGC catalog according to their sizes and central brightness in galaxies, which affect precise polarization detection in galaxies.2) We conducted polarimetric observations using Okayama Optical Polarimetry and Spectrometry system (OOPS) at Okayama Astrophysical Observatory. CCD polarimetric dara obtained with OOPS have been stored in CD-ROM as a basic data-base for polarimetric study on magnetic fileds in galaxies.3) We developped a "Guide Start Search System", which makes polarimetric observation much easier and more reliable than ever. With thanks of this guiding system, we can performed our polarimetric observation of so many galaxies (Reference #1).We performed study on capability of polarimetric observation with the SUBARU telescope at Mauna Kea, Hawaii. We show we can carry polarimetric observation of external galaxies using the FOCAS instrument (Reference _<2 and >3).

1）极化观察非常重要，并且是揭示外部星系中磁性结构的关键。为了为此目的对星系进行系统的极化观察，我们根据它们的大小和星系中的中心亮度从UGC目录中选择了71个星系，这会影响星系中的精确极化检测。2）我们使用okeama pallimimetry和spectimetry和spectimentry和spectimentry and Spectmetry System（OOPS）在Okeama sateroptorsical operservity进行了极化观察。用OOPS获得的CCD极化DARA已存储在CD-ROM中，作为银河系中磁性归档的极化研究的基本数据库。3）我们开发了一个“指南启动搜索系统”，这使极化观察结果比以往任何时候都变得更加容易，更可靠。在此指导系统的感谢下，我们可以对如此多的星系进行偏光观察（参考＃1）。我们对夏威夷Mauna Kea的Subaru望远镜进行了有关偏光观察能力的研究。我们表明，我们可以使用焦点仪器（参考_ <2和> 3）对外部星系进行偏光观察。
