围绕10.4米GTC望远镜的中西天文双边合作主要由中国科学院国家天文台、南京天文光学技术研究所、西班牙加那利天体物理研究所（IAC）、西班牙GTC天文台四家机构联合参与。2015年，西班牙研发与创新国务秘书Carmen Vela Olmo女士访问国家天文台，开启了中西双边天文合作历程。2016年时任中国科学院院长白春礼院士和Carmen Vela Olmo女士在西班牙共同见证了中西双边天文合作协议的签署。

　　在协议框架下，我国天文学界将以高分辨率超稳定光谱仪为实物贡献，成为世界上已建成的最大单口径光学望远镜GTC的合作伙伴，既可缓解我国长期缺乏大口径光学望远镜观测资源的困境，又可为GTC增添一台实力强大的终端仪器，提升其高分辨率光谱观测能力，共同推动系外行星、恒星、星际介质、黑洞、星系与银河系化学演化等前沿研究领域的全面提升。

　　当前，中方技术团队完成了GTC高分辨率超稳定光谱仪的前期设计工作，概念方案2019年6月在西班牙顺利通过国际评审，相关工作已获得中国科学院批准立项。

　　同时，在中国科学院国际合作项目的支持下，双边合作已在黑洞、化学元素丰度特殊恒星等方面取得了重要的研究成果。光谱仪的研发将助力我国科学家获得更多的GTC保障观测时间。

　　过去六年中，中西双方已组建了合作团队，积极促进科学研究、仪器研制、人才交流等合作落地。公平、共赢的中西天文合作，必将协助两国天文及相关科技界取得更丰硕的成果。

　　The China-Spain astronomical bilateral cooperation focus on the 10.4-meter Gran Telescopio CANARIAS (GTC) and involves the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC， CAS), Nanjing Institute of Astronomical Optics & Technology (NIAOT) of CAS, Instituto de Astrofísica de Canarias (IAC), and the GTC Observatory of Spain. This cooperation was started in 2015, when Ms. Carmen Vela Olmo, State Secretary for the Ministry of Science and Innovation of Spain, visited NAOC. In 2016, a signature of the agreement of China-Spain bilateral cooperation was witnessed by Professor Bai Chunli, Academician and then the President of CAS, and Ms. Carmen Vela Olmo in Spain.　　In the past six years, the astronomers from both China and Spain have established collaboration teams to actively promote cooperation in scientific research, instrument development, and talent exchanges. A fair and win-win China-Spain astronomy cooperation will surely help both countries to achieve more fruitful results on astronomy and related scientific and technological communities. 

　　Under the framework of the agreement, the Chinese astronomical community will become a partner of the world's largest single-aperture optical telescope through providing a High-Resolution ultra-stable Spectrograph (HRS) as in-kind contribution to the GTC. HRS will be a powerful terminal instrument on GTC, significantly enhancing its capabilities of high-resolution spectroscopy. This collaboration will alleviate China's long-term predicament lacking of large optical telescopes, and comprehensively improve the areas on cutting-edge research, such as exoplanets, stars, interstellar medium, black holes, galaxies, and the chemical evolution of our Milky Way.

　　In June 2019, the conceptual design of HRS passed the international review in Spain. At present, the Chinese technical team has completed the preliminary design of HRS. Relevant work has been approved and will be supported by CAS.

　　With the support of the CAS International Cooperation Project, the China-Spain bilateral astronomical cooperation has already achieved high-impact research results in black holes and chemically peculiar stars. The development of HRS will help Chinese scientists to obtain guaranteed observational time on GTC.
