Abstract:
患者,男,51岁,曾行2次甲状腺手术。1992年术后病理不详。2007(2次手术)术后病理证实为甲状腺髓样癌。术后口服甲状腺素片至今。20136月因左腰部间歇性隐痛就诊我科。PET/CT见双侧肾上腺占位,FDG代谢轻度增高。20136月行左侧肾上腺切除术,术中见左侧肾上腺多发结节占位,直径约3 cm。术后病理:左侧肾上腺髓质结节状增生。右侧肾上腺占位暂未给予特殊处理,以随访为主。随访至201310月底,患者一般情况良好,血压稳定,右侧肾上腺占位较前相仿。
A 51-year-old man underwent two thyroid surgeries. The first operation called left thyroidectomy was in 1992 with unclear pathological results. He underwent right thyroidectomy in 2007 and medullary thyroid carcinoma was pathologically confirmed. He has been in oral administration of thyroxine after the first surgery. The patient consulted the doctor in our department because of suffering from the pain in his left hip on June 2013. PET/CT examination revealed bilateral adrenal masses with slightly increased FDG metabolic. And then he underwent a left adrenalectomy. During the operation, the surgeon found multiple nodules occupying the left adrenal gland with a diameter of about 3 cm. Histopathological report: nodular hyperplasia of the left medulla. We follow up the right adrenal mass which was given no special treatment until October

Abstract:
有效的水资源管理与调度是促进流域可持续发展的重要保障。流域水资源统一调度和管理是一项涵盖规划、建设和实时调度管理的系统工程,本文通过长江流域水库调度管理实践,阐述了流域水资源统一调度和管理的关键环节和主要技术,包括流域水资源管理规划、水资源管理的战略格局、流域水资源调度管理实践等。同时探讨了工程措施应用对流域产生的影响以及社会经济发展需求对流域水资源管理带来的新挑战。
Effective water resource management and regulation is an important guarantee for promoting the sus-tainable development of river basin. The integrated operation and management of water resources in a basin consists of processes of planning, construction and real-time operation, which is a complex syste-matic procedure. The water resources management practices in Changjiang River shows that operation of single reservoir and cascade reservoirs is a crucial and typical non-engineering measure for IWRM. In this paper, the key process of basin water management and main technical support was proposed, including river basin and water resource planning, the strategy and practices of water resources management in Changjiang River. Changes and challenges of water resources management in the Changjiang River were also discussed. It is found that the current focus of water resources management in Changjiang River is how to satisfy the increasing requirements from social economic development, and how to ease the adverse effects of large water construction.

初级银行——后危机时期中小企业融资模式创新

财会月刊 , 2011,
Abstract: 由美国次贷危机引发的全球性金融危机使得中小企业的生存空间被挤压,而融资难已成为后危机时期影响中小企业发展的关键问题。2010年5月国务院发布了《关于鼓励和引导民间投资健康发展的若干意见》,在此背景下,有必要探讨如何利用规模庞大的民间资本解决中小企业的资金紧缺问题。本文通过构建初级银行这一区域性的基础融资平台,为有效缓解中小企业融资难提供参考。  【关键词】初级银行中小企业融资民间资本利率市场化中小企业发展至今,已成为我国国民经济的重要组成部分,对我国经济的发展起着十分重要的作用。目前,我国约有99%的企业是中小企业,中小企业对GDP的贡献超过60%,对税收的贡献超过50%,提供了75%以上的城镇就业岗位。然而,以美国次贷危机为导火索的全球性金融危机使得中小企业的生存空间被大幅压缩。解决好中小企业的融资难问题显得十分关键。本文拟结合2010年5月国务院发布的《关于鼓励和引导民间投资健康发展的若干意见》,就民间资本与中小企业融资之间构建融资平台,提出建立初级银行的构想,为有效缓解中小企业融资难提供参考。  一、中小企业融资现状

Abstract:
本课题基于LANDSAT卫星影像,通过运用ERDAS、ARCGIS等软件进行波段整合、几何校正、拼接、裁剪,根据适宜滇中地区的土地利用/土地覆盖体系,结合监督分类法对滇中地区的土地利用类型进行分类,并进行精度评价和分类后处理等步骤,将滇中地区土地利用类型分为耕地、林地、草地、水域及水利设施用地、住宅用地和其它土地。通过统计得出,滇中地区林地面积占总面积的绝大多数,所占比例高达56.02%,草地位居第二,在总面积中占26.5%,剩余的17.48%包括耕地、水域及水利设施用地、住宅用地和其它土地。
This article was based on Landsat satellite images, did the band integration, geometric correction, mosaic, cropping by using ERDAS, ARCGIS software, according to the land use/land cover system which was fit for mid-Yunnan, combined with supervised classification method to do the classification of the land use types in mid-Yunnan, in addition, carried out accuracy assessment and did the processing after classification and other steps. The land use types of mid-Yunnan were divided into arable land, forest land, grassland, water and water conservancy facilities land, residential land and other lands. Through the statistics obtained, forest land area made up 56.02%, accounting for majority of the mid-Yunnan total area; grassland was in second place, accounting for 26.5% of the total area; the remaining 17.48% included arable land, water and water conservancy facilities land, residential land and other lands.

Abstract: 随着社交网络的兴起,网民对信息资讯的速度和实时性提出了更高的要求。传统搜索引擎通过费时的网络爬虫抓取网页,建立索引,这已远不能满足用户的需求。相比之下,实时搜索能直接从网络捕获数据流,从而更迅速地满足用户对实时信息的需求。目前国内外已经出现了一些实时搜索引擎,如美国的OneRiotGoogleCollectaScoopler等,它们通过抓取TwitterFacebookDigg等社交网络上用户随时发布的海量信息,给人们提供最新的搜索内容。
With the rise of social network, Internet users have put forward higher request on the speed and real-time for information. Through the time-consuming web crawler, traditional search engine grab the web page, and establish the index, which can not meet the users’ needs. In contrast, the real-time search can capture the data flow directly from the network, thus it meets the needs of the users for real-time information more quickly. Some real-time search engines have already appeared at home and abroad, such as the United States OneRiot, Google, Collecta and Scoopler, etc., which provide people with the latest search content through grabbing the mass information released by the users on Twitter, Facebook, Digg, etc. at any time.

Abstract: ?针对多径衰落信道下分布式多输入多输出正交频分复用(mimo-ofdm)系统中频偏信道联合盲估计难的问题,提出了一种有效的多频偏多信道联合盲估计方法。该算法利用盲解卷积分离算法接收信号的同时得到有频偏影响的多个信道,对分离后的多个信号进行逐个频偏估计,补偿整体信道并去除信道模糊度,得到有效的信道估计值。仿真结果表明,与基于导频的频偏信道估计方法相比,所提算法可在5db获得1e-6的频偏估计精度,在15db左右获得1e-2的信道估计精度,实现了分布式mimo-ofdm信号的多频偏多信道联合盲估计。
