These regions are called \"photodissociation regions.\" We have made far-infrared spectroscopic observations of many photodissociation regions with a 50cm Balloon-borne Infrared Telescope (BIRT) and a liquid helium cooled Fabry-Perot spectrometer. We also adopted a frequency switching method to observe diffuse compoents efficiently. The spectral lines we observed are [CII] (^2P_<3/2>-^2P_<1/2>. 158μm) and [OI] (^3P_1-^3P_2,63μm), both of which are the most important coolants in photodissociation regions. We have observed many kinds of photodissociation regions, including active star-forming regions (M17 and NGC6334), central regions of our Galaxy, and wide regions along the Galactic plane. Our observations showed that (1) photodissociation regions are very clumpy and that FUV penetrates deep into clouds, (2) photodissociation regions are ubiquitous, and (3) photodissociation regions are not minor interstellar components but their total mass in our Galaxy amounts to 40% of that of molecular gas.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166942000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"名古屋大学理学部"},{"subitem_text_value":"京都大学理学部"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"名古屋大学理学部"},{"subitem_text_value":"京都大学理学部"},{"subitem_text_value":"アリゾナ大学スチュワード天文台"},{"subitem_text_value":"アリゾナ大学スチュワード天文台"},{"subitem_text_value":"東京大学理学部天文教育研究センター"},{"subitem_text_value":"郵政省通信総合研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中川, 貴雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥田, 治之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"芝井, 広"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松原, 英雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"舞原, 俊憲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水谷, 耕平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西村, 徹朗"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 行泰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"広本, 宣久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAGAWA, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKUDA, Haruyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIBAI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUHARA, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MAIHARA, Toshinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIZUTANI, Kohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Low, F.
