We detected species such as C2, NH2 , and[OI] . To characterize the comet, we estimated the gas-production rates of C2 and NH2 relative tothat of H20 and the gas-to-dust ratio based on the Haser model. The dust color was also estimatedby the method of Jewitt & Meech (1986).The gas-production rates were Q(NH2/H20)=0.23%, Q(C2/H20) = O.10%. These values aretypical for the Borrelly class which is characterized by the depletion of C2 molecule relative tothat of the Halley class. Since about 30% of detected comets belong to the Borrelly class, comet55P/Tempel-Tuttele can not be a peculiar comet, at least from spectroscopic point of view.The gas-to-dust ratio was log(Q(H20)/Afp)= 26.7, which means this comet was gas-rich relativeto comet Halley. The dust color was roughly estimated by using continuum windows, andthe dust reddening was 9.69% per 1000Å, which was consistent with other nine comets observedby Jewitt & Meech (1986).It is plausible that comet 55P/Tempel-Tuttle is not an exotic comet at any rate, except thefact that it is the parent body of the Leonid meteor stream.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4636313000","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":"0288-433X","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":"AA10455137","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"県立ぐんま天文台"},{"subitem_text_value":"県立ぐんま天文台"},{"subitem_text_value":"埼玉県立三郷工業技術高等学校"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"国立天文台"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Gunma Astronomical Observatory"},{"subitem_text_language":"en","subitem_text_value":"Gunma Astronomical Observatory"},{"subitem_text_language":"en","subitem_text_value":"Saitama Pref.
