摘要:
Instruments in space make it now possible to observe our cosmic environment not only in the visual and radio wavelengths but also in the infrared, ultraviolet X ray and γ ray parts of the electromagnetic spectrum. This reveals that quite a few of the generally accepted astrophysical concepts can no longer be valid. But, in order to understand what we see, it is essential to clarify what laws of physics govern the cosmic phenomena. As (at least by volume) more than 99.99% of the universe consists of plasma, plasma physics is essential. Another and at least as important a change in our basic astrophysical concepts is due to the in situ measurements in the magnetospheres of the planets. These have demonstrated that cosmic plasmas have properties drastically different from those that were rather generally accepted as late as 5 or 10 years ago. These latter were based on the classical theory of plasmas (by Chapman and Cowling and others) which was admirable from a mathematical point of view but unfortunately did not agree very well with experiments and observations. Measurements in the laboratory and in situ measurements by spacecraft have shown that plasma physics must be considered more as an empirical than a purely mathematical science [Alfven, 1981, chap. I and IV, 1982]. In the following we shall follow an essentially empirical approach to certain important astrophysical problems

摘要:
Recently,Russell and Reiff[1984] presented a flow‐diagram analysis of the AGU publication process indicating how publication delays naturally occur. Perhaps because o f space limitations, their diagram did not include some important control statements. For example, according to their diagram, all manuscripts are either published or enter an endless loop. In fact, many papers end up elsewhere: As fish wrappers, in filing cabinets, or in non‐AGU publications. (Accepted papers can end up in the same places, but they have the advantage of having been published in an AGU journal.) Significantly, the number of times the paper passes through the submission‐refereeing loop (NJ) is not just journal dependent.NJalso depends inversely onnD, the density of Dogma in the paper. We are concerned with the publication process also and are motivated by reports thatNJis unusually large in the case of certain distinguished colleagues, particularly when introducing new concepts or criticizing older approaches. Some suggestions are offered here to speed publication and consequently to assist in the smoother functioning of the scientific method in geoph

摘要:
Major environmental concerns of the low‐level radioactive waste management operations at Oak Ridge National Laboratory (ORNL) are that the groundwater in this location is near the soil surface and that there is a possibility of water infiltrating the disposal trenches at old solid waste storage areas (SWSA's). In the current SWSA (SWSA 6), a group of trenches (49‐Trench area) collect and hold water with seasonal fluctuations ranging from 1 to 2 m. This seasonal wetting of the buried waste has resulted in the movement of9OSr to a surface stream within the disposal area. To reduce infiltration and prevent waste leaching, the entire 0.44‐ha 49‐Trench area was sealed with a bentonite clay cover in October 1976. Subsequent monitoring indicated that the cover had not corrected the trench water problem, which suggested a faulty seal, an alternate recharge source,

摘要:
It is widely accepted that atmospheric electricity is a fundamental discipline of great importance; it is equally true that progress in some parts of this field has been erratic. It has frequently attracted bright young people who have left for “hotter” areas. Specifically, it supplied much of the talent in cosmic ray physics, and, more recently, the field was decimated by the literally greener pastures in space science. Still, there remains a hard core of serious workers who are convinced of the ultimate scientific importance of their field including relevance to other areas (meteorology, space science, and possible relationships between th

摘要:
The Morphostructure of the Atlantic Ocean Flooris a useful review of the principal morphologic, tectonic, sedimentary, and geophysical features of the Atlantic Ocean. The treatment of these topics is primarily a descriptive one based mostly upon data collected by Soviet scientists. The book is a recent translation of a 1980 edition published in Russian and as such suffers in two important ways: (1) The material and views presented take virtually no cognizance of research done since the mid‐1970s and (2) the actual translation is often awkward (for example, platform tectonics instead of plate tectonics; ocean bottom spreading instead of seafloor spreading; bathography instead of bathyorographical or, better still, morphology

摘要:
Nearly 40 scientists, space physics data system managers, and NASA Headquarters personnel, all members of the Data System Users Working Group (DSUWG), met at Marshall Space Flight Center (MSFC) on May 2 and 3, 1984, to discuss the status and future direction of the Space Physics Analysis Network (SPAN) pilot project. SPAN was recently established by Code EI and Code T at NASA Headquarters as a pilot project based on the recommendations of the DSUWG (seeEos, February 7, 1984, p. 46) and the urging of many scientists of the space plasma physics community. SPAN will use as its foundation the SCAN (Space‐Plasma Computer Analysis Network) system managed by Marshall Space Flight Center. Code EE at headquarters has chartered the DSUWG, currently chaired by D.N. Baker of Los Alamos, to provide the scientific user guidance for the future development of the SPAN. SPAN will continue to be managed by MSFC but funding and policy review will be handled by Code EI to coordinate all the headquarters space science activities on the syste
