 [PDF]


Modeling and Simulation (MOS) , 2013, DOI: 10.12677/MOS.2013.24006
Abstract:
建立了二自由度汽车油气悬架系统模型,分析了油气悬架和车身模型的非线性特性。运用AMEsim仿真软件,通过模型对不同的激振频率的时域和频谱响应分析,验证了油气悬架非线性振动模型的正确性仿真结果表明,系统产生了接近激振频率分数(或整数倍)的频率分量,造成亚谐波(或超谐波)共振,导致系统振动不稳定。
The non-linear characteristics of hydro-pneumatic suspension and car body model are analyzed in this paper, and two-degree-of-freedom vibration model of hydro-pneumatic suspension is modeled. Dynamic time domain and frequency response to different vibration frequency verify the correctness of the non-linear model by AMEsim simulation software. Results show that the unstable vibration state is due to subharmonic or ultraharmonic resonance produced by the frequency components which are close to the fraction or the integer times of excitation frequency in the system.

利津油田利7区复杂断块油藏有效储层预测方法研究
 [PDF]


Journal of Oil and Gas Technology (JOGT) , 2015,
Abstract:
针对储层预测技术在复杂断块油气藏研究中存在的问题,以利津油田利7区为对象开展相关研究。首先通过岩心、测井、试验等数据的分析,认为利7区古近系沙河街组二段下亚段(EsL2)为三角洲前缘亚相沉积,主要发育水下分流河道、前缘席状砂等微相。在对利7区三维地震资料的振幅、频率、相位及能量等多种属性进行可行性分析基础上,利用沙河街组二段(Es2)不同砂泥岩组合正演模型研究认为,仅仅利用振幅属性或频率等属性难以区分不同类型的组合,因而引入了弧长地震属性进行有效储层预测。通过对研究区弧长地震属性的提取,并与沉积、储层分布图件对比分析表明,三者具有较好的相关性,从而实现了利用弧长地震属性对研究区复杂断块区有效储层的预测

This study focuses on the personal traits of Cai Yuanpei with the research method of bio-psychography. Cai Yuanpei’s Personality Adjective Rating Scale was made based on the analysis of biographical materials about Cai Yuanpei, and 180 valid questionnaires were collected. On the one hand, adopt factor analysis and reveal three factors as follows: virtue, uprightness and versatile talents. On the other hand, dealing with the data in the analysis of multi-dimensional scaling, classify Cai Yuanpei’s personality traits into 7 categories: versatile talents, visions, justice, uprightness, integrity preservation, doing for justice and perseverance. Through the comparison of factor analysis and multi-dimensional scaling analysis, multidimensional scaling analysis can be found in more comprehensive and accurate interpretation of Cai Yuanpei’s personalities. After analysing the cause of Cai Yuanpei’s personality, researchers have found that which were formed with the integral impacts from internal and external causes of himself, family and society to western and eastern multi-culture. Finally, this study illustrates the influences that Cai Yuanpei’s personal charm has made on the Chinese university education reform.

Abstract:
牛栏江红石岩形成大型堰塞湖后,及时收集堰塞湖区水文气象和工程设计资料,通过洪水几率、洪水标准、设计洪峰流量和设计时段洪量分析,及时为堰塞湖排险处置提供了洪水分析计算成果,得出堰塞湖在8至9月份发生年最大洪水的几率是大的,为35%;并得出5年和20年一遇的设计洪峰流量,1 d、3 d、5 d、7 d设计洪量成果;当发生5年和20年一遇洪水,通过水量平衡方程进行调洪演算来分析堰塞湖的最高洪水位和最大库容,1 d、3 d、5 d、7 d设计库容超过堰塞湖最大库容的有6个,漫堰的概率为75%;通过洪水漫堰后淹没、溃堰风险分析,得出风险范围是极大的,在堰塞湖上下游83 km的河段,有4213人,6个水电站会受到淹没和溃坝影响。因此,红石岩堰塞湖的排险处置是非常紧迫的。
When great landslide lake was formed at Hongshiyan in Niunan River, the hydrometeorological data and engineering design data of landslide lake area were collected rapidly. Through analysis to flood proba-bility, flood standard, design flood peak flow and the flood volume in designing period, the analysis and calculation results of the flood were provided timely to dispose the risk at Landslide Lake. The results indicated the probability of annual maximum flood in this landslide lake was larger in August and Sep-tember, which was about 35%. The flood routing on the flood of every 5 years and 20 years was carried out by the water balance equation to analyze the highest flood level and the largest capacity of the lake. The results showed that there were 6 design capacities in 1 day, 3 days, 5 days and 7 days were larger than the maximum capacity of the landslide lake, the frequency of overflowing weir was about 75%. The risk area is great through risk analysis to submergence and breach when flood overflows cofferdam, 4213 people and 6 hydropower stations alone the upstream and downstream of 83 km landslide river reach may be affected by submergence and weir break. Therefore, risk-elimination is urgent for the land- slide lake of Hongshiyan.

Abstract: 本文引入不确定线性互补问题鲁棒解的概念。而且,我们证明:如果不确定二次规划问题的robust Counterpart,这一鲁棒优化问题的存在最优解\"\" ,并且最优值为0,那么\"\"就是不确定线性互补问题的鲁棒解。我们讨论当不确定集为随机对称分布时,线性互补问题的求解。借助于概率论知识,给出\"\" 为almost reliable鲁棒解的充要条件。
In this paper, we introduce the notion of robust solution of uncertain linear complementarity problems. We prove that, if robust counterpart to uncertain quadratic programming—a robust optimization problem, has a optimal solution \"\" , and the optimum value equals to zero, then \"\" is the robust solution of the uncertain linear complementarity problem. By probability theory, we discuss linear complementarity problems under a random symmetric uncertainty, and obtain sufficient and necessary conditions of almost reliable robust solution.
