不同语言的文本之间必然有距离。母语为汉语的学生在阅读英语文本时也存在着距离。阅读的距离不仅包括因语言不同而产生的文本距离，还包括历史距离、文化距离、身份距离、审美距离等。该文从《春播》一文分析学生与英语文本的阅读距离。
Distance exists between texts written in different languages. When Chinese students read English texts, they are faced with reading distance. Reading distance includes not only the distance between texts, but also time distance, cultural distance, iden-tity distance and aesthetic distance, etc. This paper aims to analyze the reading distance students are faced with in Spring Sowing.

基于解释水平理论,考察了心理距离的不同维度对后悔程度的影响。本研究从心理距离的四个维度展开,时间距离采用组内设计,空间距离、社会距离和概率维度采用单因素完全随机设计,312名被试随机分配至各个维度参与实验处理,检验不同心理距离是否调节着后悔程度,其中有效数据275份。结果表明：在时间距离、空间距离、社会距离、概率和假设性条件下,均出现决策时心理距离越近,对决策事件或客体的解释水平越低,随后在获得负性结果反馈时体验到的后悔就越强烈。由此可见,决策事件的心理距离越近,后悔程度越大。
Regret is a kind of cognitive emotion which occurs when the outcome will be better than it was if one made a different choice.Individual''s interpretation to the situation affects judgment and decision making, sequentially af-fects the intensity of regret.Construal Level Theory ( CLT) is a social cognitive theory which assumes that the psy-chological distance perceived from the objects or events can make people product different construal levels, and then influence judgment and decision making.The research based on the CLT explored how psychological distance influences individual''s regret intensity.This study was operated from four dimensions of psychological distance ( temporal, spatial and social distance, probability) , and we surveyed 302 students from Soochow University and picked up 275 valid data.Every participant should finish one of the situational questionnaires randomly.The results showed that Individuals experience more regret under the near temporal, spatial, so

基于图的半监督学习的一个关键问题是：图上顶点之间的距离度量的有效性问题。为了解决这个问题，提出了基于图的半监督学习的距离度量改进方法。通过在现有密度敏感的距离度量方案中添加补偿参数的方法，使得改进的距离度量方案不但能够有效地扩大不同类别的高密度区域样本间的距离，同时还能缩小相同类别中样本之间的距离。将改进的距离度量方案应用到聚类算法中，来验证改进的距离度量方案的有效性。实验结果表明：改进的距离度量方法能够有效地扩大不同类别间距离，增强类内聚合度。

激光雷达的距离像是雷达成像系统区别于其他的成像系统(如红外成像系统、可见光成像系统)所特有的信息，它是对目标精确识别、打击的基础。如何对距离像去噪直接决定了下一步目标定位、识别的精确性。针对雷达距离像的特点，提出了一种基于对比度调制方法对条纹管激光雷达的距离像去噪方法，通过提取距离像噪声的对比度信息，用其调制未经过去噪的距离像，从而得到距离像中的噪声图像，最后用未经过处理的距离像减去噪声图像，得到图像即为去噪后距离像。研究表明该方法去噪效果明显，在去噪的同时很好地保持了距离像的边缘信息，去噪后图像的信噪比明显提高，距离像的属性也没有改变，这是其他方法对距离像去噪所不具有的优点。
Lidar range image is particular information of lidar system that other imaging systems (such as IR imaging system and optical imaging system) can not provide. It is the foundation for precision target identification and attacking. How to denoise directly determines the accuracy of target recognition. According to the characteristics of the radar range image, a method was presented for streak tube imaging lidar based on contrast-modulation method. The noise contrast information of range image was extracted to modulate original image, so as to get noise image, and finally range image without processing was used to minus the noise image to get the image which was denoised. The research result shows that the effect of this denoising method is obvious and the edge information of range image also keeps intact. After denoising, the signal noise ratio (SNR) of the range image is significantly improved. The attributes of range image does not change. This is the advantage the other methods for r

在现有多种距离度量和传统谱聚类算法的基础上，提出了一种新的基于有效距离的谱聚类算法（spectral clustering based on effective distance，SCED）。SCED算法通过稀疏重构系数来构建样本与样本之间的有效距离，从而代替传统谱聚类算法中的欧氏距离，进行样本之间的相似度评估。与传统距离度量相比，有效距离不仅利用了样本对之间的距离信息，同时考虑了目标样本与其他所有相关样本之间的距离信息，因而该距离度量具有全局特性。在UCI标准数据集上的实验结果表明，SCED算法能有效提高聚类效果。
Based on existing distance metrics and the traditional spectral clustering algorithm, this paper proposes a new spectral clustering based on effective distance (SCED). Specifically, the proposed SCED algorithm uses effective distance to replace conventional Euclidean distance, by considering global properties of data that are reflected by sparse reconstruction coefficients. In effective distance, the similarity of a sample pair is evaluated by using not only the distance between these two samples, but also distances between one specific sample and other related samples. Sparse reconstruction coefficients are employed to reflect such global relationship among samples. The experimental results on ten UCI benchmark datasets demonstrate the efficiency of the proposed SCED algorithm.

机动车能否安全行驶,在一定程度上取决于机动车驾驶人掌握行驶安全距离的能力。机动车行驶安全距离是指从发现障碍开始制动,到最后完全停止所行驶的距离,它包含纵向行驶安全距离和横向行驶安全间距。纵向行驶安全距离取决于制动停车距离;横向行驶安全距离应根据路面的不同、气候的变化灵活掌握。由此可见,机动车驾驶人必须根据机动车的行驶速度、道路状况、气候条件、装载状况等因素,灵活掌握机动车的行驶安全距离,以充分保证其行驶的安全性。
To some extent, how to safely drive motor vehicle depends on whether the driver masters the ability to drive a safety distance. Motor vehicle safety distance is measured from the beginning of the braking when obstacles are found to the last full stop, which contains longitudinal and transverse driving safety distance. Longitudinal driving safety distance depends on the stopping distance; safety distance of transverse driving varies according to the road surface difference and climate change. Thus, the motor vehicle driver must flexibly master driving safety distance in order to fully ensure the driving safety according to the driving speed, road conditions, weather conditions, loading conditions and other factors.

通过考察时间距离、社会距离和概率距离对跨期选择和风险选择的影响,探究跨期选择和风险选择心理过程的相似性,并检验不同心理距离影响决策的相似性。结果发现,无论是时间距离(实验1)、社会距离(实验2)、还是概率距离(实验3),心理距离越远,被试在跨期选择中越倾向于延迟选项,在风险选择中越倾向于风险选项。研究认为,在跨期选择和风险选择中,选项的表征结构和选项整体评价时不同选项特征的相对权重具有相似性。随着心理距离增加,与高识解相联系的金额特征的相对权重增加,与低识解相联系的时间和概率特征的相对权重降低,这使得被试更倾向于选择金额较大的延迟和风险选项。同时,研究发现三类心理距离对两类决策有相似影响,进一步验证了不同心理距离的本质相似性。
Temporal distance, social distance and probabilistic distance are three basic dimensions of psychological distance. It has been proved that different kinds of psychological distance have similar effects on cognitive representations of events. In general, distant events are represented as high-level construals, whereas near events are represented as low-level construals. As events become more distant, the high-level construals become more influential in shaping preference whereas the low-level construals become less influential (Liberman, Trope, &Stephan, 2007;Liberman,&Trope, 2008;Trope,&Liberman, 2010). This study investigates the effects of temporal, social and probabilistic distance on intertemporal choice and risky choice. We hypothesize that different kinds of distance have similar effects on intertemporal and risky choice, based on the assumptions that these three kinds of distance share the same nature as psychological distance, and that intertemporal choice and risky choice hav

已有的测地距离变换算法顾及了障碍物的影响,但存在较大的距离误差。针对这一问题,提出了一种在障碍空间中进行精确的测地距离变换的蛮力算法。该算法将障碍物的凸角点视为中继源,利用中继源计算特征像元到障碍物背后的背景像元的最短可通行距离。与已有的测地距离变换算法不同,该算法选取的中继源位于最短距离传播路径上,偏移量为零。实验结果表明,该算法不存在距离计算误差,其距离准确性不受障碍物数量、位置和形状的影响。
The existing geodesic distance transform algorithms consider the influence of obstacles,but the calculated distances have errors.A brute-force algorithm is suggested for accurate geodesic distance transform in a space with obstacles in this paper.It takes the convex corners on obstacles as relay sources to calculate the length of the shortest passable path from foreground pixels to background pixels behind the obstacles.The relay sources of this algorithm lie on the shortest passable paths from foreground pixels to background pixels,and thus distance errors are avoided,better than other relay sources suggested in the existing geodesic distance transform algorithms.Experimental results show that there is no distance error in the new algorithm,and it is applicable for distance transform in space with obstacles in any shapes.
