...Carbon (from Latin: carbo "coal") is a chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5,730 years.[14] Carbon is one of the few elements known since antiquity.[15] There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon.[16] The physical properties of carbon vary widely with the allotropic form. For example, graphite is opaque and black, while diamond is highly transparent. Graphite is soft enough to form a streak on paper (hence its name, from the Greek word "γράφω" which means "to write"), while diamond is the hardest naturally-occurring material known. Graphite is a very good conductor, while diamond has a very low electrical conductivity. Under normal conditions, diamond, carbon nanotubes, and graphene have the highest thermal conductivities of all known materials. All carbon allotropes are solids under normal conditions, with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and other transition metal carbonyl complexes. The largest sources...

...营销财务指标分析 按照世界营销学权威人士——菲利普.科特勒的理论,对企业营销活动的控制主要包含一下几个方面:年度营销计划控制、盈利能力控制、效率控制及战略控制。为便于理解我们将其归纳如下: 控制类型 | 主要负责人 | 控制目的 | 控制方法 | 年度营销计划控制 | 高层管理当局中层管理当局 | 检查计划目标是否实现 | 销售分析;市场份额分析;费用销售额分析;财务比例分析;市场基础的评分卡分析。 | 盈利能力控制 | 营销主管人员 | 检查公司在那些方面赚钱,那些方面亏损 | 盈利情况:产品,地区,细分顾客群,销售渠道。 | 效率控制 | 直线和职能管理当局,营销主管人员 | 评价和提高经费开支效率以及营销开支效果 | 效率:销售队伍,广告,促销和分销,营销效益等级评核。 | 战略控制 | 最高管理当局,营销审计人员 | 检查公司是否在市场、产品和渠道等方面正在寻求最佳机会 | 营销审计,营销杰出表现,公司道德与社会责任评价。 | 以上的几种控制都会涉及到相关的财务分析,尤其是年度营销计划控制、盈利能力控制和效率控制。我们将采用如下的杜邦财务分析体系,以提高企业的资本净值报酬率为核心,展示财务指标和营销效率之间的关系,从中选取几个重要的财务指标,利用可从上市公司的公报中获得的公开信息展开我们的分析。 首先我们介绍以下几个无论是从营销控制还是从财务控制的角度都具有重要的意义财务指标: (一)净资产收益率 净资产收益率=净利润/企业净资产 净资产收益率又称权益净利率,反映的是企业股东权益的收益情况,在以股东权益最大化为企业目标的前提下,作为一个综合性指标,其高低可以最直接和最明显的反映和评价企业的生产经营状况。 (二)盈利率 1:销售利润率 销售利润率=净利润/销售收入 净利润:是指企业在一定会计期间内实现的收入减去费用后的净额,反应了企业在一定会计期间的经营业绩和获利能力,反映了企业投入产出效率和经济效益。 商品销售收入:是指符合商品所有权的主要风险和报酬已转移给买方;企业既没有保留与所有权相联系的继续管理权,也没有对已售出的商品实施控制;相关的收入和成本能够可靠计量并且与交易相关的经济利益能够流入企业等四项条件的商品销售收入。 该指标是一个盈利情况的综合性指标,它既可以反映企业销售收入的增长状况,也可以反映企业的利润水平增加情况。它可以通过将销售收入和费用按不同的产品、细分市场、区域及分销渠道等进行划分,从而为各类别市场编制损益表的方法来评价企业的营销效率: 1) 产品销售利润率:用来评价企业的各产品线,确定企业的最佳产品组合。如某公司前3个产品的盈利占总盈利的70%,而后97个产品的盈利占总盈利的30%,其中后90个产品亏损了1亿元。在此情况下企业应着手重新配置企业的资源以调整企业的产品结构,实现企业整体利润水平的提高。 2) 细分市场销售利润率:面对最终消费者,企业通常会根据目标市场顾客的年龄、性别、职业、收入水平、家庭婚姻状况等对消费者进行市场细分,在此基础上确定企业的细分市场营销策略,企业在确定该策略时必须考虑各细分市场的盈利状况,以确定企业的重点营销对象。如某公司白领人群市场的盈利占总盈利的150%,而蓝领人群市场的盈利占总盈利的-50%。在此情况下,企业应调整其细分市场策略,实现营销重点的转移,以提高企业的整体盈利水平。 3) ...

...Sdfsd fsssssssssssssssssssss sssssssssssssssssssssssssssssssssssssssssssss ssssssssssssssssss sssss ssssss sss sssssssss ssssssss ssssssssssssssssss ssssssss sssssssssss fsdferwerwerwerwer Wer W W Er W Er W Werw EASHINGTON (AP) -- The Obama administration on Monday will roll out a plan to cut earth-warming pollution from power plants and 30 percent by 2030, setting in motion one of the most significant actions to address global warming in U.S. history. The rule, which is expected to be final next year, will set the first national limits on carbon dioxide, the chief gas linked to global warming from the nation's power plants. They are the largest source of greenhouse gases in the U.S., accounting for about a third of the annual emissions that make the U.S. the second largest contributor to global warming on the planet. The Environmental Protection Agency regulation is a centerpiece of President Barack Obama's plans to reduce the pollution linked to global warming, a step that the administration hopes will get other countries to act when negotiations on a new international treaty resume next year. Despite concluding in 2009 that greenhouse gases endanger human health and welfare, a finding that triggered their regulation under the 1970 Clean Air Act, it has taken years for the administration to take on the nation's fleet of power plants. In December 2010, the Obama administration announced a "modest pace" for setting greenhouse gas standards for power plants...
