体会科学方法加强科学探究

我们对大自然的了解，是科学家们用一种有序、系统的（科学）方法形成和获得的．科学方法告诉我们发现自然法则的途径，如图1所示．     

EBIT trapping program

The LLNL electron beam ion trap provides the world's only source of stationary highly charged ions up to bare U. This unique capability makes many new atomic and nuclear physics experiments possible.     

体验科学探究——物理通报编初中《物理》修订版"探索者"教学实践与体会

随着教育改革的不断深入,新一轮基础教育课程改革已进入实验推广阶段.这次课改的一个显著特点是对基础教育的总目标做了重新定位.它要求为学生的终身学习打基础,即新课程应有利于学生自主、多样、持续地发展,体现以人为本的教育理念.为此,全日制义务教育<物理课程标准>对课程理念做了这样的表述:①注重学生发展,改变学科本位;②从生活走向物理,从物理走向社会;③注重科学探究,提倡学习方式多样化;④注重学科渗透,关心科技发展.这一阐述,对物理课程价值功能做了清晰的定位.     

Hadron program at COMPASS

The fixed target COMPASS experiment at CERN offers the opportunity to search for exotic mesons and glueball candidates in the light quark sector with unprecedented statistics.Preliminary results from the2008 data taken with an incoming negative hadron beam(190 GeV/c,mainly pions)on a liquid hydrogen target are presented.New detectors dedicated to hadron beam measurements have been added.These give access to rare neutral and kaonic channels.An amplitude analysis which will allow to fit simultaneously diffractively and/or centrally produced resonances will be described and compared with those used in the CERN WA102and BNL E852 experiments.     

科学计算应用程序探讨

科学计算应用程序是科学计算研究的成果集成,其研制不同于通常的计算机应用软件.随着科学计算研究的不断深入和高性能计算机的迅猛发展,应用程序越来越依赖于实际应用和高性能计算的交叉融合,迫切需要革新程序的研制思路,发展研制方法.文章简要介绍了科学计算应用程序的主要特征,分析了应用程序面临的主要困难,探讨了研制应用程序的新思路和新方法.     

XFELO Scientific Opportunities Retreat

The first XFELO Science Workshop was held at SLAC National Accelerator Laboratory, Menlo Park, CA, from June 29 to July 1, 2016. The main purpose was the discussion of scientific opportunities an XFELO extension of the LCLS-II complex in the future would enable. Chaired by Jerry Hastings (SLAC), it brought together more than 40 researchers from institutes around the world.     

Complementarity and Scientific Rationality

Bohrs interpretation of quantum mechanics has been criticized as incoherent and opportunistic, and based on doubtful philosophical premises. If so Bohrs influence, in the pre-war period of 1927–1939, is the harder to explain, and the acceptance of his approach to quantum mechanics over de Broglies had no reasonable foundation. But Bohrs interpretation changed little from the time of its first appearance, and stood independent of any philosophical presuppositions. The principle of complementarity is itself best read as a conjecture of unusually wide scope, on the nature and future course of explanations in the sciences (and not only the physical sciences). If it must be judged a failure today, it is not because of any internal inconsistency.     

Research program for the nuclotron

Information is given about experiments at the accelerator complex of the Laboratory of High Energies (LHE) at the Joint Institute for Nuclear Research (JINR, Dubna) and about projects for this facility. The projects were developed by collaborations, groups, and divisions of the LHE, as well as of other JINR laboratories and of institutes from the countries that are JINR members and from some other countries.     

Balloon program for hard-X-ray astronomy

Summary An observation program of X-ray sources in the (20÷200) keV energy band by means of a balloon-borne NaI(Tl) seintillator array was undertaken in 1980. Three balloon flights have been performed and 10 X-ray rources observed, some more than once. We present details of this balloon program and results obtained from the analysis of the Crab observation performed in October 1980. Paper presented at the 2° Convegno Nazionale di Fisica Cosmica, held at L'Aquila, 29 May–June 1984.     

Borexino and its physics program

Borexino, a real-time detector for low energy neutrino spectroscopy is under construction in the underground laboratory LNGS at GranSasso, Italy. The experiment aims for the first direct measurement of the solar ⁷Beneutrino flux.     

物体色度值的计算机模拟表征

本文以国际标准CIE(国际照明委员会)所规定的XYZ空间体系为基础，结合计算机计算的方法，通过利用光栅光谱仪所测的透射光谱来计算出准确的颜色，并可直接在计算机屏幕上将颜色表达出来，最后结合例子给出实验结果和相应的理论分析，结果表明：实验结果和理论分析的符合是相当好的．     

Nuclear physics program at MAX-lab

The upgrade of the MAX-lab injector and the construction of MAX Ⅲ, provided the opportunity for upgrading the tagged-photon facility and thus lead to the possibility of more extensive program in nuclear physics research. This upgrade increased the injected electron energy to an eventual maximum of 250 MeV and allows for the extraction of electrons from the MAX Ⅰ ring operated in the stretcher mode. The first stretched beam was delivered in September 2005. The tagged-photon facility was commissioned in parallel with the commissioning of new experimental equipment. The PAC approved experimental program is current in progress, including measurements of pion photoproduction below the △(1232). The efforts at the tagged photon-facility are pursued within an international collaboration with around fifty members.
