Only radiative processes are taken into account so that electron conduction is not included. For parison purposes we present some opacity tables for the RossAller and CoxTabor metal abundances. Although in many regions the OPAL opacities are similar to previous work, large differences are reported. For example, factors of 23 opacity enhancements are found in stellar envelop conditions.

Abstract: With the aim to provide observational constraints on the evolution of the galactic disk, we have derived abundances of 0, Na, Mg, Al, Si, Ca, Ti, Fe, Ni, Y, Zr, Ba and Nd, as well as individual photometric ages, for 189 nearby field F and G disk dwarfs. The galactic orbital properties of all stars have been derived from accurate kinematic data, enabling estimates to be made of the distances from the galactic center of the stars‘ birthplaces. 結(jié)構(gòu)式摘要 ? Our extensive high resolution, high S/N, spectroscopic observations of carefully selected northern and southern stars provide accurate equivalent widths of up to 86 unblended absorption lines per star between 5000 and 9000 angstrom. The abundance analysis was made with greatly improved theoretical LTE model atmospheres. Through the inclusion of a great number of ironpeak element absorption lines the model fluxes reproduce the observed UV and visual fluxes with good accuracy. A new theoretical calibration of T(eff) as a function of Stromgren b y for solartype dwarfs has been established. The new models and T(eff) scale are shown to yield good agreement between photometric and spectroscopic measurements of effective temperatures and surface gravities, but the photometrically derived very high overall metallicities for the most metal rich stars are not supported by the spectroscopic analysis of weak spectral lines. ?

Abstract: This article describes recent technical developments that have made the totalenergy pseudopotential the most powerful ab initio quantummechanical modeling method presently available. In addition to presenting technical details of the pseudopotential method, the article aims to heighten awareness of the capabilities of the method in order to stimulate its application to as wide a range of problems in as many scientific disciplines as possible.

Title: HERWIG A MONTECARLO EVENT GENERATOR FOR SIMULATING HADRON EMISSION REACTIONS WITH INTERFERING GLUONS SCI 被引用955 次 ? Source: COMPUTER PHYSICS COMMUNICATIONS, 67 (3): 465508 JAN 1992:《計算機物理學(xué)通訊》荷蘭 Elsevier ? Abstract: HERWIG is a generalpurpose particlephysics event generator, which includes the simulation of hard leptonlepton, leptonhadron and hadronhadron scattering and soft hadronhadron collisions in one package. It uses the partonshower approach for initialstate and finalstate QCD radiation, including colour coherence effects and azimuthal correlations both within and between jets. This article includes a brief review of the physics underlying HERWIG, followed by a description of the program itself. This includes details of the input and control parameters used by the program, and the output data provided by it. Sample output from a typical simulation is given and annotated.

Title: PLANTRESPONSES TO ATMOSPHERIC CO2 ENRICHMENT IN THE FACE OF ENVIRONMENTAL CONSTRAINTS A REVIEW OF THE PAST 10 YEARS RESEARCH ?

Abstract: This paper presents a detailed analysis of several hundred plant carbon exchange rate (CER) and dry weight (DW) responses to atmospheric CO2 enrichment determined over the past 10 years. It demonstrates that the percentage increase in plant growth produced by raising the air39。s CO2 content is generally not reduced by less than optimal levels of light, water or soil nutrients, nor by high temperatures, salinity or gaseous air pollution. More often than not, in fact, the data show the relative growthenhancing effects of atmospheric CO2 enrichment to be greatest when resource limitations and environmental stresses are most severe.
