目的：斗轮挖掘机回转支承上部结构的重量和重心位置不仅在设计过程中非常重要,在斗轮挖掘机组装完成后和运转时同样重要。本文旨在研究各参数对重心位置的影响。方法：1.分析比较由数值模拟和实验得到的静态稳定性基本参数;2.构建上部结构的3D模型（图1-3）,并根据斗轮挖掘机组装完成后的重量分布对模型进行质量修正;3.对上部结构进行负载和应力分析。结论：1.上部结构一个较小的质量变化（1.5%）会导致重心位置一个较大的变化（902 mm）,从而不得不明显增加配重的重量（24 t）来保持平衡;2.构建的3D模型可以得到精确的上部结构重量分布和重心位置;3.由DIN 22261-2标准规定的眼板应力被证明并不安全。

采用Ａｌ－Ｄａｈｈａｎ的滴流床高压数据，确定了Ｈｏｌｕｂ详细模型中速率滑移因子ｆｖ和剪切滑移因子ｆｓ的关联式，并将简单模型和详细模型的预测与实验结果进行了比较．结果表明：在高压下详细模型的预测效果明显优于简单模型，且与实验值的偏差较小，使得Ｈｏｌｕｂ的基础模型的预测能力大大增强．

AIM: To investigate the accuracy of the strain histogram endoscopic ultrasound(EUS)-based method for the diagnostic differentiation of patients with pancreatic masses. METHODS: In a prospective single center study, 149 patients were analyzed, 105 with pancreatic masses and 44 controls. Elastography images were recorded using commercially available ultrasound equipment in combination with EUS linear probes. Strain histograms(SHs) were calculated by machine integrated software in regions of interest and mean values of the strain histograms were expressed as Mode 1(over the mass) and Mode 2(over an adjacent part of pancreatic tissue, representing the reference area). The ratio between Mode 2 and Mode 1 was calculated later, representing a new variable, the strain histogram ratio. After the final diagnosis was established, two groups of patients were formed: a pancreatic cancer group with positive cytology achieved by fine needle aspiration puncture or histology after surgery(58 patients), and a massforming pancreatitis group with negative cytology and follow-up after 3 and 6 mo(47 patients). All statistical analyses were conducted in SPSS 14.0(SPSS Inc., Chicago, IL, United States).RESULTS: Results were obtained with software for strain histograms with reversed hue scale(0 represents the hardest tissue structure and 255 the softest). Based on the receiver operating characteristics(ROC) curve coordinates, the cut-off point for Mode 1 was set at the value of 86. Values under the cut-off point indicated the presence of pancreatic malignancy. Mode 1 reached 100% sensitivity and 45% specificity with overall accuracy of 66%(95%CI: 61%-66%) in detection of pancreatic malignant tumors among the patients with pancreatic masses. The positive and negative predictive values were 54% and 100%, respectively. The cut-off for the new calculated variable, the SH ratio, was set at the value 1.153 based on the ROC curve coordinates. Values equal or above the cut-off value were indicative

Global Communications and Changing Perspectives:The World as a World Society

Journalism and Mass Communication 2017年第11期7卷 589-597页

作者： milorad Djuric College of Social Work Speech and Language Therapy and Occupational Therapy(Department of Social Work) BelgradeSerbia

In this paper we will analyze the world as a world *** assumption is that,thanks to global communications,the world has become a unique social ***,it is necessary to make an analysis of the changes that have occurred in the society-state *** the contemporary understanding,societies are constituted as relatively closed,self-referential systems,in which the world of life is framed by the borders of national *** and extending the communication process has relativized the boundaries of such closed systems,creating an opportunity for the establishment of a world ***,the practical political(infra)structure is still fixed on old patterns and,objectively,lags behind this change,creating a legitimacy deficit in the political *** it is necessary to look at the world from a new perspective.
