The Solar-A ( 'Yohkoh' ) satellite was launched in August 1991, and has been returning X-ray data of the solar corona and the solar flares. An important knowledge which Yohkoh has brought to us is that a full understanding of the coronal physics inevitably requires supporting ground-based observations. Such observations are being carried out both in Japan and in China, in optical and radio wave bands.This project aimed at combining high quality optical and radio data obtained at the observing facillities in both countries together with X-ray data from Yohkoh. We have conducted a similar cooperative research program in 1992-93, so that the scientists in the two counties were ready for the present research program. In order to report the results of cooperative researches, in the period from August 31 to September 5,1994, a workshop on solar physics was held in Dunhuang, China. Thirteen Japanese and about thirty Chinese scientists participated in the workshop. Studies combining Yohkoh X-ray data and ground-based optical or radio data have been initiated in China, which we believe are the contributions from this cooperative program. Another topic of discussion in this project is the space program on solar physics in the future. Both countries have plans to launch an optical telescope to observe the sun in high spatial resolution.The continuation of this program was strongly supported from the participants of both countries. Chinese side will apply for Chinese Science Academy and Natural Science Foundation of China, and Japanese side will apply for the Ministry of Education international research grant, and also for Japan Society for the Promotion of Science for support.

solar - a （'Yohkoh'）卫星于1991年8月发射，一直在返回太阳日冕和太阳耀斑的x射线数据。Yohkoh带给我们的一个重要知识是，要全面了解日冕物理学，不可避免地需要支持地面观测。这种观测正在日本和中国的光学波段和无线电波波段进行。该项目旨在将两国观测设施获得的高质量光学和无线电数据与Yohkoh的x射线数据结合起来。我们在1992- 1993年进行了一个类似的合作研究计划，因此两国的科学家为目前的研究计划做好了准备。为了报告合作研究的成果，1994年8月31日至9月5日在中国敦煌举行了一次太阳物理研讨会。13名日本科学家和约30名中国科学家参加了研讨会。结合Yohkoh x射线数据和地面光学或无线电数据的研究已经在中国启动，我们认为这是该合作计划的贡献。在这个项目中讨论的另一个话题是未来关于太阳物理的空间计划。两国都计划发射一架光学望远镜，以高空间分辨率观测太阳。该项目的继续开展得到了两国参会者的大力支持。中方将申请中国科学院和中国自然科学基金，日方将申请教育部国际研究经费，并向日本科学促进会申请支持。
