U.S. Participation in the XXIInd General Assembly of the International Union of Radio Science

无线电科学是一项跨学科的工作，涵盖许多不同领域的基础和应用研究，如射电天文学、大气研究和电信。这项研究的大部分是国际性的，很大程度上是因为无线电波不会停留在国界上，而是在极长的距离内传播。无线电科学的国际性导致了1919年国际无线电科学联合会(通常称为URSI)的成立。国际无线电通信研究所的目标是：1)促进无线电通信的科学研究；2)在国际范围内协助和组织无线电研究，并鼓励讨论和发表结果；3)促进测量和测量仪器的标准化；4)促进和协调对电信科学方面的研究。URSI通过三年一度的大会实现其许多目标。这次会议的会议记录被广泛和公开地分发，并接触到广泛的受众。美国在联合国大会中的充分参与显然是可取的。因此，我建议国家科学基金会向国家科学院颁发旅行补助金，以确保合格的美国研究人员参加将于1987年8月24日至9月2日在以色列特拉维夫举行的XXIInd大会。

Radio Science is a cross disciplinary endeavour, encompassing basic and applied research in many diverse areas, such as radioastronomy, atmospheric research and telecommunications. Much of this research is international in character, due largely to the fact that radio waves do not stop at national boundaries and propagate over extremely long distances. The international character of radio science led to the foundation of the International Union of Radio Science (commonly designated as URSI) in 1919. The aims of URSI are: 1) to promote the scientific study of radio communications; 2) to aid and organize radio research on an international scale and to encourage discussion and publication of the results; 3) to facilitate the standardization of measurements and measuring instruments; and 4) to stimulate and coordinate the study of the scientific aspects of telecommunications. URSI accomplishes many of its objectives through a triennial General Assembly. Proceedings of this meeting are widely and openly distributed and reach a broad audience. Adequate U.S. participation in the General Assembly is clearly desirable. Consequently, I recommend that the National Science Foundation award a Travel Grant to the National Academy of Sciences to ensure the participation of qualified U.S. researchers at the XXIInd General Assembly to be held in Tel Aviv, Israel, August 24-September 2, 1987.
