正把"人"看作一种资源,是现代人事管理的一个创新。当今世界,企业之间、地区之间以及国与国之间的竞争,实质上就是人特别是人才的竞争。美国钢铁大王卡内基曾说过:"你将我的所有工厂、设备、市场、资金全部拿去,但只要保留我的人员,四年之后,我仍是一个钢铁大王"。人才已成为当前企业最重要的资本,企业失去了人才,就等于失去了生命力。  相似文献

江泽民主席在1999年6月17日西北五省区国有企业改革和发展座谈会上明确指出,现在我们正处在世纪之交,应该向全党和全国人民明确指出,必须不失时机地加快中西部地区的发展,特别是抓紧研究西部地区的大开发。江泽民  相似文献

正当我国城镇化进程进入下半场,伴随着白热化的市场竞争,勘察设计行业的人才竞争进入了新时期。一方面,行业人才吸引力下降,行业越来越难以吸引到优秀人才。各大招聘网站的应届生就业调查研究显示,体制方面,应届生更热衷于相对稳定的国有企业、事业单位和国家机关;行业方面,应届生更期望从事互联网等"新基建"相关产业,工程建设行业受到明显冷落。另一方面,行业人才流动率居高不下。  相似文献

萤石作为一种重要的非金属战略性矿产资源,受到各国(地区)的高度重视。由于全球萤石资源储量有限、分布不均,萤石产品的供需矛盾不断增强,激化了萤石资源进出口之间的竞争。本文主要研究了萤石资源国际贸易,以无机氟化工产业链为切入点,选取酸级萤石、电子级氢氟酸、六氟磷酸锂为研究对象,运用复杂网络方法,构建了2000—2020年全球萤石产品进口竞争网络,分析其格局、演变特征,国家(地区)间竞争特点以及中国萤石产品的竞争状况。结果发现:全球萤石产品之间的竞争越来越激烈,各阶段的累积度分布都遵循幂律分布。竞争强度占比前20%的国家(地区)显示出更直观的集中化趋势。近20年来美国一直是酸级萤石进口竞争的矛盾中心。电子级氢氟酸和六氟磷酸锂的进口竞争网络的核心国家(地区)是不断演变的。建议中国等萤石资源储量丰富的国家(地区),合理规划萤石产业,优化萤石资源供需格局、促进萤石产业健康可持续发展。  相似文献

方解石在成岩环境中的溶解度与地下水化学特征、温度等有着极为密切的关系。通过CaCO3溶解沉淀反应平衡以及地下水中的Ca2+活度可以确定不同温压的地下水条件下方解石的溶解趋势。地下水溶液的pH值和温度是方解石溶解度最直接的控制因素。方解石溶解趋势可以通过CaCO3电离反应的吉布斯自由能(ΔG)来判断:ΔG<0时,反应向溶解方向进行;ΔG>0时,反应向沉淀方向进行。根据方解石的水岩反应理论,对塔河油田34口井的奥陶系地层水进行了ΔG的统计计算。结果显示:塔河油田现今地下水条件有利于方解石的溶解,西部地区较东部溶解趋势强,北部地区溶解趋势相对较弱。这为定量了解塔河地区埋藏岩溶趋势及该地区的储层评价预测提供了理论依据。  相似文献

羊庄岩溶水系统地下水是山东枣庄滕州市、山亭区和薛城区城市供水及部分工业用水的主要来源。基于地下水环境演化趋势评价指标体系的羊庄岩溶水系统地下水环境演化趋势的研究,对地区饮用水安全、工农业生产和经济社会可持续发展具有重要意义。以羊庄岩溶水系统地下水为研究对象,用地下水环境演化趋势评价指标体系对系统地下水环境演化趋势进行研究,结果显示,除山亭断块和辛召断块部分低山丘陵区以波动平衡演化为主以外,其他地区地下水环境演化趋势以劣向演化为主,约占系统总面积的2/3,亟需采取相关措施抑制这一趋势。  相似文献

祁漫塔格地区构造-岩浆作用与成矿   总被引:2,自引:0,他引:2  
对祁漫塔格地区构造-岩浆作用的研究表明,岩浆活动峰期为加里东期—印支期,并有从北向南逐渐变新的趋势。区域成矿峰期与岩浆活动峰期是一致的,主要成矿母岩为岩浆弧相俯冲-碰撞杂岩。另外,祁漫塔格地区主要发育北东向和北西向两组断裂带,北东向断裂是影响区域成矿的主控因素。  相似文献

International unity is becoming ever stronger in this country owing to an increasing similarity in the development of the cultural environment. This comprises the provision of all the country's republics with a sufficient number of schools, theatres, and other institutions and cultural information media in accordance with the needs of the population. An important part is played by the rise in ‘the general educational level, as well as the level of professional qualifications and skills. Among all the Soviet nations and nationalities, this rise being more rapid among formerly backward peoples. Prominent among the factors of internationalization is the progressive development of the nationalities’ cultural resources, while professional culture is being increasingly brought within the reach of the masses.The implementation of the nationalities policy promotes the all-round development of all Soviet nations and nationalities, their drawing together, the upsurge of the individual capabilities of every Soviet citizen.  相似文献

The Global Stratotype Section and Point (GSSP) for the base of the Silurian System was defined in 1985. Since that time, a number of researchers have suggested that this section has serious deficiencies for use as a GSSP. As a result, in 2000, the Subcommission on Silurian Stratigraphy (SSS) proposed undertaking a formal restu@ of this GSSP, which was subsequently approved by the International Commission of Stratigraphy (ICS). The result of this restudy was the formal proposal that the current GSSP, at 1.6 m above the base of the Birkhill Shale, at Dob's Linn, Scotland, should be maintained as the same locality and stratigraphic level, but the bios- tratigraphical definition of the boundary should be revised. The previously defined, basal Silurian grapto- lite zone, the Parakidograptus acuminatus Zone, should be subdivided into a lower Akidograptus ascensus Zone and a higher E acuminatus Zone. The base of the A. ascensus Zone, marked by the first appearance of A. ascensus, should be regarded as the biostratigraphic mark for the base of the Silurian. This proposal has now been formally approved by the SSS and ICS, and ratified by International Union of Geological Sciences. This is the first GSSP to undergo formal restudy and redefini- tion, and the proposal also included a recommended procedure for restudy of GSSPs.  相似文献

It is known from observations that the center of mass of the Moon does not coincide with the geometric center of its figure, and the line connecting these two centers is not aligned with the direction toward the center of the Earth, instead deviating toward the Southeast. This stationary deviation of the axis of the inertia ellipsoid of the Moon to the South of the direction toward the Earth is analyzed. A system of five linear differential equations describing the physical libration of the Moon in latitude is considered, and these equations are derived using a new vector method taking into account perturbations from the Earth and partly from the Sun. The characteristic equation of this system is obtained, and all five oscillation frequencies are found. Special attention is paid to the fifth (zero) frequency, for which the solution of the latitude libration equations are stationary and represents a previously unknown additional motion of the rotational axis of theMoon in a cone with a small opening angle. In contrast to the astronomical precession of the Earth, the rotation of the angular-velocity vector is in the positive direction (counter-clockwise), with the period T 3 = 27.32 days. On this basis, this phenomenon has been named “quasi-precession.” This quasi-precession leads to a stationary inclination of the major axis of the inertia ellipsoid of theMoon to the South (for an observer on Earth), making it possible to explain one component of the observed deviation of the center of mass of the Moon from the direction toward the Earth. The opening angle of the quasiprecession cone is approximately 0.834″.  相似文献

Important tendencies in development of the world mineral-resources sector at the beginning of the 21st century were an increase in production and consumption of mineral materials differentiated by types of metals and nonmetallic mineral raw materials, by countries and regions, as well as the concentration of the production of mineral raw materials in a small number of countries, and a reduction in industrial reserves of minerals in the world economy, even at the current stage of their extraction. These tendencies should be taken into account in working out a strategy for development of the Russian mineral raw-material base.  相似文献

Taking the example of W Sudan, an analysis of the climatic incidents leading to the two recent famine disasters is made. On this natural background, the human side is investigated. Focus is directed towards the fragile economic structure of the famine-prone population groups. An early-warning system for famine in the Sahelian Zone is proposed taking grain production and storage, livestock development and the relationship between the prices of livestock and grain as major indicators.  相似文献

东濮凹陷北部沙三中亚段广泛发育盐岩和烃源岩,这两个看似不能共存的物质却在这里互层共生。该时期研究区沉积特征为多盐韵律与多层烃源岩互层共生、连续沉积,单个盐韵律厚度从几米到十几米,烃源岩有机质丰度高、类型好。平面上,两者在湖盆沉积沉降中心共生;垂向上,高有机质丰度、好干酪根类型与高盐度地层具有较好的对应关系。因而成为恢复古气候和古环境的重要研究对象。通过岩石学、古生物学以及Sr/Ba、B/Ga、(V+Ni+Mn)、Fe/Mn、Sr/Cu、Mg/Ca、V/(V+Ni)、稀土元素含量和氯同位素等方法对凹陷北部沙三中亚段的沉积环境进行研究。结果表明,凹陷北部沙三中亚段为深水沉积的还原环境,古盐度较高,达到半咸水-咸水沉积;微量元素和孢粉化石特征表明研究区沙三中亚段为温暖潮湿的环境。  相似文献

The structure of the eastern Pyrenees consists mainly of south-directed thrusts involving basement and cover rocks. An antiformal stack developed by the piling up of basement thrust sheets which outcrop in the Axial zone. These structures account for a thin-skinned thrust model rather than a vertical fault model in which the Axial zone would be essentially autochthonous, and the North-Pyrenean fault the axial plane of a fan thrust system. New data from the Eastern Pyrenees and the thin-skinned model suggest that(1) the structure east of the Pedraforca nappe is similar to that of the Central Pyrenees; (2) the cover rocks of the South-Pyrenean units and of the Axial zone-after restoration—built up a northwards-thickening prism consistent with the existence of a unique Pyrenean sedimentary basin during Mesozoic time; (3) the Axial zone is only a complex antiformal stack developed as a part of South-Pyrenean system related to the Paleogene thrusting-tectonics. The Axial zone palaeogeographic area had no special meaning during Mesozoic time.  相似文献

郯庐断裂南段研究进展与断裂性质讨论   总被引:13,自引:3,他引:13  
据1:5万区域地质调查和专题研究资料,就郯庐断裂带是否南延与消失的原因,其与大别—苏鲁造山带交截形成的假位错效应,以及与中新生代沉积盆地形成演化的关系等作了新的阐述。在此基础上,讨论了郯庐断裂带是否为巨大的左行平移断层或转换断层。认为郯庐断裂带可能是在“古郯庐带”的基础上于早侏罗世重新活动、白垩纪强烈活动的地堑型枢纽断裂带。  相似文献
