Then steady forced vibration of the nonlinear Disk spring-mass system under base excitation and force excitation is obtained individually by using the Fourier series analysis and harmonic balance method.

详细探讨了考虑静力载荷影响的、具有弹性非线性和Coulomb摩擦阻尼非线性的碟簧元件的建模和动力学特性，首先利用Fourier级数分析技巧和平均法研究了非线性碟簧-质量系统的自由振动，讨论了影响自由振动的振幅和频率的各种因素，然后利用Fourier级数分析技巧和谐波平衡法研究了地基激励和力激励下非线性碟簧-质量系统的强迫振动，通过详细的参数研究考察了非线性碟簧元件的减振性能特征，最后采用修正的稳定性分析方法研究了两种激励下稳态响应的稳定性。

When Julie tells him she's pregnant, he feels compelled to somehow find a way to support his family, but the only option seems to be falling back into crime with his old pal Jigger.

The nuclear of the method is the newly developed HHT for nonstationary and nonlinear time series analysis, which consists of the Empirical Mode Decomposition and Hilbert Spectral Analysis.

该方法对桥梁结构健康性的最终判断依据是基于数据的非线性特征、自由振动和强迫振动的频率对比、桥梁对轻荷载及重荷载的响应。

Suppose that the law does not force us to follow certain forms of religion, or systems of association, or methods of education, or regulations of labor, or regulations of trade, or plans for charity; does it then follow that we shall eagerly plunge into atheism, hermitary, ignorance, misery, and greed?

设想如果：法律不强迫我们跟从某种形式的宗教，或结社系统，或教育方法，或劳动管制，或贸易管制，或慈善计划；那么必然的我们就会狂热的深陷于无神论，隐居，无知，苦难和贪婪之中？

In this thesis, firstly, some main models have been checked on their accuracy, and the reliability of MACORS code has been verified by the RELAP5/MOD2 code on five transient conditions for QSNP: loss of flow; loss of offsite power; incontrollable control rod withdrawal; the feed-water temperature increasing and the feed-water lost. The results obtained are very satisfactory. Secondly, MACORS is used to calculate the operating and accident transients for QSNP, and the analysis results are significant to real engineering. And finally for MNRS, MACORS is used to simulate the steady-state natural circulation heat-removed capacity and the transient behaviors from forced circulation to natural circulation. Some important conclusions are obtained by the analysis results.

本论文首先从各方面对核动力系统中最主要的、热工水力特性最复杂的反应堆和蒸汽发生器进行单独验证和理论分析，其次分别利用RELAP5/MOD2程序和MACORS程序对秦山核电站的双环路失流、全厂断电、反应性事故引入、主给水参数变化及丧失主给水五种瞬态工况进行了计算，结果符合很好，从而证明了本程序模型的准确合理性，选择数值方法的有效性和编制程序的正确性；尔后，利用MACORS程序对秦山核电站的多种运行及事故瞬态进行了分析，得出了具有工程价值的结论；对船用核动力装置的稳态自然循环载热能力以及相应参数的特性、强迫循环与自然循环的过渡工况等进行了仿真分析，所得结论对我国核动力船舶的设计，运行以及安全审评具有重要的意义。

绑架罪是指，劫持、扣押某人或以其他方法非法剥夺他人人身自由，并将其置于自己或第三人实力控制之下，以杀死、伤害或继续扣押该人质相威胁，强迫第三方满足其一定要求，作为释放人质的明示或暗示的条件的行为。

objective to investigate the relation between psychological factors and functional dyspepsia.methods scl-90was performed in50patients with fd and30health controls.results there were significant difˉference in somatic,interpersonal sensitive,anxious,depressive,phobic,hostile and paranoic scores of scl-90between two groups（p.05）.somatization,interpersonal sensitivity,anxiety and depression were positively associated with the severity of fd.conclusion there were varied psychological problems in fd patients,and the treatment should be individualized.

目的 探讨功能性消化不良和心理因素之间的关系。方法采用症状自评量表（scl-90）对连续就诊的50例符合罗马ⅱ标准的功能性消化不良患者及30例匹配的正常对照进行测评。结果 fd组的躯体化、人际关系紧张、焦虑、抑郁、强迫、恐怖、敌对和偏执因子分均高于正常对照组，其中焦虑、人际敏感、躯体化、抑郁与fd的严重程度成正相关。结论功能性消化不良存在不同程度的心理障碍。
