我们应德国科技交流协会(Deutscher Akademischer Austauschdienst,简称DAAD)的邀请,于1979年第三季度赴德意志联邦共和国,分别到汉堡大学地球物理系和弗朗霍夫建筑物理研究所进行为期三个月的研究访问。由于这次访问具有研究讨论的特点,因此除了一般的参观外,在这期间就双方都感兴趣的研究课题进行了讨论,交流了研究资料并参加了有关的实验和考察。同时我们还访问了一些声学研究机构、大学和工厂。旅德期间我们分别参观了哥廷根大学第三物理研究所、德国物理技术计量院、弗朗霍夫无损检测研究所、弗朗霍夫材料强度研究所、马克斯—普朗克生物物理化学研究所、德国水文研究所、德国国防部水声和地球物理研究所、Krupp—Atlas公司、Honeywell Elac公司、Isover公司、Teroson公司和重型机器公司等。在研究访问和参观的过程中德国朋友十分热情地接待了我们,多方设法,仔细周到地安排研究访问计划,使我们充分地感受到中德两国人民之间的深厚友谊。
At the invitation of Deutscher Akademischer Austauschdienst (DAAD), we went to the Federal Republic of Germany in the third quarter of 1979 for three months respectively at the Department of Geophysics at Hamburg University and the Fraunhofer Institute for Building Physics Study visit. Due to the characteristics of the study and discussion, this visit discussed the research topics of interest to both sides in addition to the general visit, exchanged research materials and participated in relevant experiments and investigations. We also visited a number of acoustic research institutes, universities and factories. During our trip to Germany, we visited the Third Institute of Physics of the Göttingen University, the German Institute of Physics and Technology, the Fraunhofer Institute for Nondestructive Testing, the Fraunhofer Institute for Material Strength, the Max Planck Institute for Biophysical Chemistry Institute of Hydrology and Geophysics, German Ministry of Defense, Krupp-Atlas, Honeywell Elac, Isover, Teroson and Heavy Machinery. During the study visit and visit, German friends received us with great enthusiasm and tried their best to carefully arrange the study visit plan so that we fully felt the profound friendship between the two peoples.
