Abstract Twin screw extruder at 190 C was used fabricating PP/PE in presence of cross-linking agent in different ratio. PP/PE blends were then irradiated with electron beam with 500 MeV for 5 times. The cross-linking was confirmed with the solution gel analysis, Fourier Transformation infrared spectrum and thermal analysis. Non-isothermal crystallization kinetics of PP/PE blends were analyzed as proposed by Ozawa. The extending components were 2, 3 and 4 depending upon the samples composition and modification suggesting different growth geometrics, rod, disk, and sphere type. Differential scanning calorimetry was used to obtain the melting and crystallization properties of the PP/PE blend.
摘要采用双螺杆挤出机在190℃下以不同比例添加交联剂制备PP/PE。然后用500 MeV的电子束辐照PP/PE共混物5次。通过溶液凝胶分析、傅里叶变换红外光谱和热分析证实了交联的存在。根据Ozawa的建议,分析了PP/PE共混物的非等温结晶动力学。根据样品组成和改性的不同,延伸组分分别为2、3和4,表明不同的生长几何形状,棒状、圆盘状和球形。采用差示扫描量热法测定了PP/PE共混物的熔融和结晶性能。

An Analysis of Recipient Activities in Mandarin Chinese Storytelling 汉语普通话讲故事中的接受者活动分析
Pub Date : 2013-07-31 DOI: 10.4156/JDCTA.VOL7.ISSUE11.37
Jee-won Lee
This study examines some ways in which storytelling recipients initiate and work through understanding or appreciation at the conclusion of a story in Mandarin Chinese conversation. Using conversation analytic frameworks, this study describes how recipients deploy various resources to end storytelling. While monitoring the recipients’ verbal and non-verbal conduct, the speaker treats the recipients’ evaluation differently from other common mid-telling response tokens. By looking at recipients’ reactions to a story and examining the ways that they propose alternative interpretations for events that a speaker describes, this study builds on previous studies of storytelling recipients as active participants in the construction of the narrative event.
本研究探讨了在汉语普通话对话中,讲故事的人在故事的结尾开始理解或欣赏故事的一些方式。使用会话分析框架,本研究描述了接收者如何部署各种资源来结束讲故事。在监控接受者的言语和非言语行为的同时,说话者对待接受者评价的方式与对待其他常见的说话性回应符号的方式不同。通过观察接受者对故事的反应,并检查他们对讲话者描述的事件提出不同解释的方式,本研究建立在之前关于讲故事的接受者作为叙事事件构建的积极参与者的研究基础上。

Abstract The accurate internal values, positions, and attitudes of the earth observation sensors should be known in terms of achieving precise location information of the objects on the ground. In this regard, this paper analyzes the effect of the internal orientation parameter bias of the sensor, especially, along-track line scanner, on the quality of the reconstructed object space. Synthetic dataset is produced based on the reasonable flight trajectories and attitudes of along track line scanner. Then, it is utilized for the various experiments while changing the altitudes of the scanner and ways of the georeferencing. Conclusively, the results show that in the case of the indirect geo-referencing, Interior Orientation Parameters(IOPs) bias does not play a crucial role when determining the object’s threedimensional coordinates. However, in case of the direct geo-referencing, IOP bias causes significant errors on the coordinates of the objects.
摘要为了获得地面目标的精确定位信息,需要了解对地观测传感器的准确内部值、位置和姿态。在这方面,本文分析了传感器,特别是沿轨扫描器的内部方向参数偏差对重建目标空间质量的影响。根据沿航迹线扫描仪的合理飞行轨迹和姿态,生成合成数据集。然后,在改变扫描仪高度和地理参考方式的情况下,将其用于各种实验。最后,结果表明,在间接地理参考的情况下,内部方向参数(IOPs)偏差在确定物体的三维坐标时不会起关键作用。然而,在直接地理参考的情况下,IOP偏差会导致物体坐标上的显着误差。
