摘要:

Any mission to Halley should be designed to maximize the science in terms of the objectives of the comet exploration program set down by the NASA Comet Science Working Group and the Space Science Board (Report of the Comet Science Working Group, NASA TM 80543,1979;Strategy for the Exploration of Primitive Solar System Bodies—Asteroids, Comets, and Meteoroids: 1980–1990, Committee on Planetary and Lunar Exploration, Space Science Board, Washington, DC, 1980). In order of priority, these objectives are: (1) to determine the chemical nature and physical structure of comet nuclei and to characterize the changes that occur as functions of time and orbital posit

摘要:

The ninth in a series of Caribbean Geological Conferences, which are held every 3 or 4 years, took place in Santo Domingo, capital of the Dominican Republic, from the 15th to 26th of August 1980. The conference, which was sponsored by the government of the Dominican Republic and the Universidad Catolica Madre y Maestra, was preceded by 2 days of field trips and was opened by President Antonio Guzman on the evening of the 17th of August. Generous support was provided by Alcoa Exploration Co., Falconbridge Dominicana, and Rosario Dominicana.Geologists and geophysicists from 25 countries presented about 130 papers on a wide variety of topics ranging from geophysics to paleontology. While the whole Caribbean area was discussed, there was special emphasis on the northern Caribbean and Hispaniola, as befitted the site of the conference. The contribution of workers from the Dirección General de Mineriá was particularly notabl
