The representatives of the people of France, formed into a National Assembly, considering that ignorance, neglect, or contempt of human rights, are the sole causes of public misfortunes and corruptions of Government, have resolved to set forth in a solemn declaration, these natural, imprescriptible, and inalienable rights: that this declaration being constantly present to the minds of the members of the body social, they may be forever kept attentive to their rights and their duties; that the acts of the legislative and executive powers of Government, being capable of being every moment compared with the end of political institutions, may be more respected; and also, that the future claims of the citizens, being directed by simple and incontestable principles, may always tend to the maintenance of the Constitution, and the general happiness.

组成国民会议的法兰西人民的代表们，相信对于人权的无知、忽视与轻蔑乃是公共灾祸与政府腐化的唯一原因，乃决定在一个庄严的宣言里，阐明人类自然的、不可让渡的与神圣的权利，以便这个永远呈现于社会所有成员之前的宣言，能不断地向他们提醒他们的权利与义务；以便立法权与行政权的行动，因能随时与所有政治制度的目标两相比较，从而更加受到尊重；以便公民们今后根据简单的而无可争辩的原则提出的各项要求，能恒久地导向宪法的维护并有助于人类全体的幸福。因此，国民会议在上帝之前及其庇护下，承认并且宣布如下的人权与公民权

Gas identity and concentration can be determined by monitoring the ionization voltage and discharge current of the gas. Gas ionization voltages of SWNTs were lower 30 voltages than MWNTs obtained by CVD, and after plasma treatment, the gas ionization characteristics of MWNTs were improved.

与化学气相沉积方法得到的直立式多壁碳纳米管相比较，旋涂法单壁碳纳米管薄膜电极的气体电离阈值电压要低30V左右，等离子处理对改善直立式多壁碳纳米管的气体放电性能有帮助。

Based on chapter two, In chapter three, the method of multiple scales is introduced to the study of the multiple-dimensional nonlinear stochastic systems under random external excitation. Using method of multiple scales, we strictly deduce the equation of modulation of amplitude and phase. The effects of random excitations are analyzed; numerical simulations verify the results. Theoretical and numerical simulations show that when the intensity of the random excitation increases, the nontrivial steady state solution may be changed from a limit cycle to a diffused limit cycle.

在第二章基础上，第三章将多尺度法引入到相应的随机系统的研究中；严格推导了系统的约简方程，用矩方法求出稳态解应满足的方程，获得一些结果；并且数值模拟结果与理论推导的结果是一致的；并注意到，与其对应的确定性系统相比较，系统响应从周期解变为近似周期解，系统的相轨线从极限环变为扩大的近似极限环；随着激励带宽的增大，此扩大的近似极限环的宽度将增大。

The time evolution of expectation values of the basic dynamic variables in a quantum system under different effective Planck constant were compared with the exact values of the basic dynamic variables in classical system. It is found, for the regular motion, the difference comes from the quantum effect; for the chaotic motion, it comes from the dynamical effect and the destruction of the dynamical system.

通过引入等效普朗克常数，将量子系统中基本动力学变量的期望值和经典系统中基本动力学变量的精确值的时间演化行为相比较，分析了两者产生差异的因素，规则运动主要是和量子效应有关，而混沌运动则是和动力学效应有关，即与系统的动力学对称性破坏相联系。

objective:to explore the method of ultrasonography in the diagnosis of oligohydramnios in late pregnancy,the association of olignophdramnios with pregnant complications and its effect on perineonate.methods:the clinical data in 84 patient with oligohydramnios from january 2004 to december 2006 in our hospital were collected,and 100 patients with normal amniotic fluid volume selected randomly served as control at the same time.the complications of pregnancy and adverse perinatal outcomes were analysed.results:afi method was much better than afv in diagnosis of oligohydramnios by ultrasonography.the combination of both methods could obviously improve the diagnostic accuracy of oligohydramnios.oligohydramnios could cause pregnant complications,the rate of cesarean section,fetal distress,asphyxia neonatorum and meconium -stained fluid improved significantly.conclusion:oligohydramnios in late pregnancy can cause adverse effect to perineonate,it is a dangerous omen to perineonate and need to be done immediately.ultrasonography is a dependable diagnostic method of oligohydramnios in late pregnancy.

目的：探讨超声诊断晚期妊娠羊水过少的方法，羊水过少与妊娠并发症的关系及对围生儿的影响。方法：收集我院2004年1月~2006年12月住院分娩足月妊娠产妇超声诊断羊水过少者84例，与临床符合率相比较，同时随机抽取同期在我院住院分娩的羊水量正常孕妇100例作为对照组，两组妊娠并发症及围生儿情况进行比较。结果：超声诊断羊水过少afi法优于afv法，两种方法结合可明显提高羊水过少的诊断准确率，羊水过少易伴发妊娠并发症，且妊娠晚期羊水过少孕妇剖宫产率及胎儿窘迫、羊水粪染、新生儿窒息的发生率明显增加，差异均有显著性。结论：妊娠晚期羊水过少会给围生儿造成不良的影响，是危险的征兆，需及时处理，超声检查是产前诊断羊水过少的可靠方法。

In this part, personal tales revealed in photography are placed in a parallel to that of the national narratives, thus emphasizing the respect of personal strifes and personal struggles. Professional shots are mixed with amateur shots to render different perspectives in story telling, and to make a showcase of the complex yet limited presence of photography in modern China society.

本单元把摄影对个人命运与事件的&个人叙事&放置于与摄影的&国家叙事&相对应的语境中，意在对人生问题以及时代中的个人经历的尊重；另外，通过职业摄影家的非职业摄影所记录的家庭与个人成长史，与国家立场的摄影表达相比较，力图呈现摄影在个体与政权两个向度上的叙事特征，呈现摄影在中国当代社会复杂丰富而又具有局限性的面貌。
