Interacademy Scientific Exchanges with Russia and Eastern Europe ,

通过这份合同，美国国家科学院(NAS)将在1991历年继续与苏联、保加利亚、捷克斯洛伐克、匈牙利、波兰、罗马尼亚和南斯拉夫的科学院进行科学交流计划。这些项目支持参与国的博士后科学家和工程师个人访问其他国家的科研设施，进行熟悉、讲授和研究。这些计划还包括鼓励年轻参与者参与和促进短期项目开发访问，以支持国家科学基金会与该地区国家的合作研究计划。这项活动促进了两个重要的计划目标：通过促进美国和外国科学家之间的专业联系来促进科学知识的发展，以及通过维持与苏联和东欧国家的非政府合作框架来支持美国的外交政策目标。多年来，美国科学家和工程师在互惠互利的框架下，使美国科学家和工程师能够接触到这些国家的科学人员和设施，学院间交换项目取得了良好的记录。

Through this contract, the National Academy of Sciences (NAS) will continue its scientific exchange programs with the academies of sciences of the U.S.S.R., Bulgaria, Czechoslovakia, Hungary, Poland, Romania, and Yugoslavia in Calendar Year 1991. These programs support individual visits by postdoctoral scientists and engineers of the participating countries to scientific research facilities of the other countries for familiarization, lecturing, and research. The programs also include special thrusts to encourage the participation of young participants and to promote short-term project development visits in support of the NSF's cooperative research programs with the countries of the region. This activity promotes two important program objectives: advancing scientific knowledge by fostering professional contacts between American and foreign scientists, and supporting U.S. foreign-policy objectives by maintaining a framework of nongovernmental cooperation with the U.S.S.R. and the countries of Eastern Europe. The interacademy exchange programs have had an excellent record over the years of obtaining access for U.S. scientist and engineers to scientific personnel and facilities of these countries in a framework of reciprocity and mutuality of benefit.
