清明上河园游客行为及经营对策研究

主题公园必须有鲜明的主题，清明上河园突出宋文化，1998年开园以来取得了一定的效益，但还存在不少问题，针对清明上河园的经营现状，为了该园更好的发展，通过问卷调查的方式系统地了解了清明上河园的游客行为，在详细分析游客行为的基础上，对该园的经营提出了建设性对策。     

Empirical Test for Earnings Management of Top Managers＇ Change in Listed Companies

Top managers play a significant role on business decision in listed companies. The frequency of top managers＇ change is rather high all along. Whether those listed companies which top managers changed can really improve performances？ In this paper, we will discuss whether listed companies improve the financial index through earning management and give some advice on top managers＇ change in listed companies in China.     

基于电阻阵的红外图像实时生成和显示系统

对基于MOS电阻阵列红外图像转换器的红外图像实时生成和显示系统的实现进行了重点论述。根据红外图像仿真原理对典型目标建模,并利用openGL和开发的图像转换等软件,完成目标动态图像数据序列的计算机生成;论述了基于128×128电阻阵列的红外图像数据处理与驱动控制技术,实现了目标动态红外亮度图像向目标动态灰度图像的转换,并利用驱动控制系统以200Hz的帧频速度驱动MOS电阻阵实时生成目标动态红外图像。该系统已在红外成像目标仿真中得到应用。     

异性作家笔下的家庭女教师形象比较

夏洛蒂·勃朗特与萨克雷分别塑造了家庭女教师形象 :简·爱与利蓓加。这两个人物形象同中有异 :她们所处的时代 ,社会出身 ,人生道路大致相同 ,但在褒贬色彩和形象内涵方面有着明显的不同。这种差异性则主要是由于创造形象的作家萨克雷与夏洛蒂·勃郎特性别不同造成的。作家性别的不同会对女性形象的塑造产生重要影响。     

Variations in Variation and Selection: The Ubiquity of the Variation-and-Selective-Retention Ratchet in Emergent Organizational Complexity, Part II: Quantum Field Theory

If the general arguments concerning theinvolvement of variation and selection inexplanations of ``fit'' are valid, then variationand selection explanations should beappropriate, or at least potentiallyappropriate, outside the paradigm historisticdomains of biology and knowledge. In thisdiscussion, I wish to indicate some potentialroles for variation and selection infoundational physics – specifically inquantum field theory. I will not be attemptingany full coherent ontology for quantum fieldtheory – none currently exists, and none islikely for at least the short term future. Instead, I wish to engage in some partiallyspeculative interpretations of some interestingresults in this area with the aim ofdemonstrating that variation and selectionnotions might play a role even here. Ifvariation and selection can survive in even asinhospitable and non-paradigmatic a terrain asfoundational physics, then it can surviveanywhere.
