Taking Mosuo people''s moving marriage as an example,this paper e-laborates this cultural phenomenon,feature,cultural value and the development and utilization of cultural resources. Furthermore,it places emphasis not only on highlighting the characteristics of local tradition,but also the effect of tourism development on the marriage in this area,thereby protecting the unique local cul-ture resources.

测试并比较广场舞与健身走锻炼对中老年女性身体素质和心理状态的影响,对比分析广场舞与健身走两者间的不同锻炼效果。方法:以141名中老年女性为实验对象,其中广场舞锻炼组50人、健身走锻炼组52人、无锻炼组39人,比较选择反应时、腹部脂肪率、坐位体前屈、心肺功能以及锻炼诱导情绪问卷等指标。结果:与健身走锻炼组相比,广场舞锻炼组每次锻炼时间更长;广场舞锻炼组的身体素质指标有好于健身走锻炼组的趋势;健身走锻炼组运动后即刻心率低于无锻炼组,广场舞锻炼组的最大吸氧量高于无锻炼组;广场舞锻炼组活力激发和积极投入分量表得分均高于健身走锻炼组。结论:广场舞锻炼组和健身走锻炼组每次锻炼都能坚持半小时以上,但广场舞更适合长期坚持;广场舞与健身走都能提高锻炼者的心肺功能,其他身体素质指标相比广场舞锻炼组有优于健身走锻炼组的趋势;广场舞锻炼组比健身走锻炼组更能起到调节心理情绪的作用。

Objective:To test and compare square dance and fitness walking on elderly women?s physical quality and mental state, comparative analysis of the different effect on square dance and fitness walking. Methods:141 elderly women as experimental subjects,including squaredance exercise group of 50 people, fitness walking exer-cise group of 52 people,non-exercise group of 39 people, comparing choice reaction, abdominal fat percentage, sit and reach,cardiopulmonary function and exercise-induced mood questionnaire and other indicators. Results:Com-pared with fitness walking exercise group, square dance exercise group exercise time longer;the physical indica-tors of square dance exercise group have a good trends in the fitness walking group;the heart rate of fitness walking exercise group less than the non-exercise group after exer-cise immediately, the maximal oxygen uptake of square dance exercise group more than non-exercise group;the square dance exercise group vitalize and actively involved

The factors restricted the machining accuracy of the reciprocating travelling WEDM is analyzed. The development strategies and implementation plans such as wire winding system ,working fluid system,pulse power supply and process database to achieve high-precision machining is proposed. The solutions not only meet the requirements of long time no-streaks high-precision single wire cutting machining,but also meet the low operating cost requirements for reciprocating travelling WEDM with repeated use of the electrode wire. Its high efficiency and wide range of processing objects make it become a future direction for high precision machining.

机车走行部的故障诊断是保障机车安全运行的重要手段之一。鉴于目前机车走行部滚动轴承故障诊断中存在的特征提取困难、故障诊断不准确等问题,提出一种基于最小二乘支持向量机(LSSVM)的故障诊断方法。通过主成分分析方法(PCA)对机车走行部滚动轴承的故障特征进行特征提取,将提取后的特征向量输入到故障诊断模型中,结合最小二乘支持向量机原理实现机车走行部滚动轴承的故障诊断。仿真结果表明,相比其他方法而言分类准确率达到了100%,模型构建时间为3.642 s,满足机车走行部滚动轴承的诊断要求。将最小二乘支持向量机引入并应用到机车走行部故障诊断领域中,为机车走行部故障诊断系统的研究与开发提供新思路和新方法。

Fault diagnosis of locomotive running gear is one of the important means to guarantee the safe operation of the locomotive. In view of existing fault diagnosis problems that the feature extrac-tion is difficult and fault detection is not accurate for the locomotive running gear rolling bearing, fault diagnosis method based on PCA-LSSVM is proposed in this paper. By using the method of prin-cipal component analysis ( PCA) , the fault characteristics of locomotive running gear rolling bearing are extracted and the extracted feature vector is input into the fault diagnosis model. The fault diag-nosis of locomotive running gear of rolling bearing is realized by combined with the principle of least squares support vector machine ( LSSVM ) . The simulation results show that compared with other methods the classification accuracy reached 100 percent and the model building time was 3 . 642 sec-onds, satisfying the demands of locomotive rolling bearing diagnosis. The application of the LSSVM to

走滑断裂是渤海辽东湾坳陷内的一类重要断裂,属于郯庐断裂带的组成部分,对辽东湾坳陷的地质结构和油气成藏都产生了重要影响。通过三维地震资料精细解释,揭示了辽东湾坳陷走滑断裂带的空间展布和分段差异变形特征。走滑断裂主要分布在辽东和辽中地区,总体呈北东走向,连续性较好,在剖面上发育花状构造,在平面上发育走滑双重构造和伸展叠瓦扇构造。通过对比不同地区走滑断裂带的变形特点,可以发现走滑断裂带具有明显的分段差异变形特征。总体上,可将辽东和辽中地区的走滑断裂带划分为南部的压扭段和北部的凸起段两大段,而且凸起段还可进一步根据凸起发育特征细分为复合凸起段、隐伏凸起段和单一凸起段。辽东凸起的形成主要受走滑断裂带的压扭性活动影响,而辽西凸起的形成主要是受地幔上隆导致的伸展作用控制,开始隆升的时间也早于辽东凸起。

As an important fault type in the Liaodongwan Depression ,strike slip faults are components of the Tan-Lu fault zone ,and they have exerted major influences on the structural framework and hydrocarbon accumulation in the depression . Based on detailed 3D seismic interpretation ,this paper reveals the spatial distribution and segmented differential deforma -tion characteristics of the strike slip faults in the Liaodongwan Depression .The strike slip faults mainly occur in the eastern and central Liaodongwan Depression ,trend northeast as a whole ,and have good continuity .They appear as flower structures on sectional view ,while appear as strike slip duplex and imbricated structures on plane view .Comparison of deformation features of strike slip faults in different areas shows that the strike slip fault zone features in obvious segmented differential deformation .The strike slip faults can be divided into two segments ,namely transpressional segment in the south and uplif-tin
