辽西—内蒙地区地壳结构的转换波测深研究

为研究华北地台、西拉木伦加里东褶皱带及贺根山海西褶皱带交界地区的深部构造,在辽西-内蒙地区进行了转换波地震测深。本文给出了转换波测深的基本结果,同时试图通过对转换波方法本身的进一步研究,给出更多的关于地壳结构和间断面性质的信息,并据此进行测深结果的构造意义的讨论。

我国温室气体排放的区域现状研究

如何应对气候变化是我国各级决策部门目前正在思考解决的问题。依据现实数据对我国温室气体排放的区域特征有个具体明确的认识。通过搜集我国能源及其它统计数据,参考IPCC提供的温室气体排放量报告方法,对2009年我国30个省份温室气体排放量的数据进行收集和测算,从区域的角度对排放总量、人均排放量、排放强度等指标进行分析。研究发现我国东中西部二氧化碳排放差异明显,规律明显。     

浙江西天目山土壤理化性质的海拔梯度格局

通过分析土壤理化性质,了解西天目山土壤理化性质的变化并验证酸沉降导致近年来西天目山柳杉衰退的观点.沿海拔梯度从350~1 350 m每隔200 m选定取样点,每个样点分3层取土样,分析土壤的理化性质.总体来看,随着海拔的升高,粗颗粒比例、土壤含水量和有机物含量增加,土壤容重和pH值随海拔的升高而降低,而总氮和总磷含量没有固定的趋势.与11年和20年前相比,土壤pH值显著降低,表明土壤呈现明显的酸化,土壤的快速酸化提供了酸沉降诱发柳杉快速衰退的证据.     

中西方礼仪差异(英文)

Since different countries have different histories and cultures,there are a lot of differences in the habit of conducts and the ceremony,especially between China and the West,the jokes and the mistakes caused by misunderstanding is not unusual.This shows that the understanding of the different etiquettes between Chinese and the Westerners is absolutely necessary.In the office,to understand each other’s customer will be conductive to the exchanges between the countries.A person who understands others’ rituals and folk customs can be seen as respecting for others and can be easier to make a good impression on the other side.     

Segment-based region of interest generation for pedestrian detection in far-infrared images

We present a region of interest (ROI) generation method specialized for nighttime pedestrian detection using far-infrared (FIR) images. Because pedestrians typically appear brighter than background in FIR images, previous research efforts primarily attempted to extract ROIs based on the intensity threshold. However this approach has problems resulting from the intensity variances of pedestrians due to their clothing and, especially in urban scenarios, and other heat sources that emit more heat than the pedestrians. In this paper, we propose a novel ROI generation method that is based on combining image segments instead of using the intensity threshold. In order to minimize dependence on brightness, we utilize the low-frequency characteristics of FIR images. As a result, our proposed method generates a small number of ROIs at an acceptable miss rate and the generated ROIs provide advantages for classification because the pedestrians are satisfactorily arranged within a bounding box. Experiments conducted indicate that our proposed method performs reliably in urban scenarios.     

浅论西部高校贫困生比例偏高的成因及对策

受西部整体经济落后等因素的影响,西部高校贫困生比例持续偏高等问题引起了社会的广泛关注。同时由于政府的资助机制还不健全,使得部分扶贫资金没有落到实处,严重阻碍了高校扶贫工作的开展。基于此种现状,本文认为将西部高校贫困生进行分类,从高校改革和提高贫困学生自身素质两方面入手解决具有重要意义。     

《大唐西域记》中关于于阗的三则故事小考

玄奘法师在《大唐西域记》中用大量的篇幅对于阗的情况做了论述,其中有三则耐人寻味的故事,将对鼠壤坟传说、蚕种传入故事、龙鼓传说进行探讨,并挖掘这三则故事的文化内涵。三则故事对于阗产生了重大影响,它们同时出现在丹丹乌里克佛教遗迹中不是偶然的。在中西、中印文化交流中,受到多元文化的影响,形成了独具魅力的于阗文化。     

论刘安《淮南子·兵略训》的民本思想

西汉淮南王刘安不喜欢弋猎狗马驰骋,但是好著书、好鼓琴,希望积阴德,千古留名.于是招募大量宾客名士著书立说,<淮南子>是其重要著述.其中的<兵略训>主要阐述的是军事思想,但又蕴舍了浓重的民本主义思想元素.这些思想元素,对中国后世的民本主义思想发展,乃至现代人民战争思想的产生和发展,不无影响作用.
