 [PDF]

Abstract:
智能电网系统拥有海量的实时采集数据,这会给电网数据中心带来巨大的存储和计算负担,而云计算的特点正是拥有强大的存储和计算能力,因此智能电网和云计算的结合能极大提高智能电网的数据存储能力和计算的有效性。由于电网数据中有隐私敏感信息,不能被包括云服务器在内的第三方窥伺和篡改。本文提出一种基于层次属性加密(HABE)的访问控制方法,能有效地实现对存放在云平台的敏感电网数据的访问控制。
There will be huge amount of real-time sensing data in the smart grid system, which would be a huge burden in storing and processing them for the data center, and the property of cloud compu-ting could just fix it up, so the integration of cloud computing and smart grid makes sense. There is private and sensitive information which can’t be known or falsified by a third party including the cloud servers in the data center, so the paper proposed an access control method that is based on the Hierarchical Attribute Based Encryption (HABE), which can control the access of the sensitive data storing on the cloud servers effectively.

煤炭工程 , 2014, DOI: 10.11799/ce201403032
Abstract: 近年来,新疆经济快速发展,但碳排放也随之迅速增加,给环境带来了很大压力。本文选择2001~2010年新疆煤炭、石油、天然气消费量为基础,测算2001~2010年新疆碳排放总量,并分析各能源消费量对碳排放量的贡献率,得出煤炭消费对碳排放的贡献最大;以三大产业产值、碳排放量为基础,建立灰色关联模型,分析三大产业和碳排放的关联度,得出第二产业与碳排放关联度最高;进而以第二产业相关行业和碳排放为基础,建立灰色关联模型,具体分析相关行业和碳排放的关联度。最后结合新疆发展现状,给出新疆发展低碳经济的政策意见。

Abstract:
破口事故是一回路严重事故,为了分析不同破口面积下一回路系统主要参数变化,本文用RELAP5建立了以秦山二期为对象的CNP600的一回路模型,设置了从小破口到大破口的七种不同面积的破口事故,并逐一进行仿真分析。仿真结果表明,在安注系统的作用下,事故对一回路安全的影响有所缓解,而某些大破口的面积对系统安全危害较大。
LOCAs are severe accidents of primary loop. In order to analyse the variation of system’s main pa-rameters between several different broken areas when there is LOCA, this paper established the model of CNP600 in RELAP5 according to Qin Shan II NPP, and set up seven broken areas from small LOCA to large LOCA to calculate. The results show that under the action of safety injection system, the impact of the accident has weakened. However, the results also indicate that some of the large broken areas are of great harm to the system.

Abstract: 经皮椎间孔镜技术属于微创技术,具有创伤小、出血少、术后恢复快、术后并发症少、对脊柱稳定性影响小等优点。最初用来治疗的疾病为腰椎间盘突出症(Lumbar Disc Herniation, LDH),即经皮椎间孔镜腰椎间盘切除术(Percutaneous Endoscopic Lumbar Discectomy, PELD)。腰椎间盘突出症是骨伤科的常见病、多发病,大部分通过保守治疗可以达到临床治愈,但保守治疗无效者需要手术治疗。传统手术治疗该病创伤大、出血多、术后恢复慢,随着微创技术的发展,经皮椎间孔镜椎间盘切除术越来越受到脊柱外科医生的青睐。此技术的应用范围也从腰椎间盘突出症扩展到腰椎不稳、椎间盘源性腰痛、腰椎管狭窄等疾病。本文将就此技术的发展概况、麻醉方法、运用范围与临床疗效作一综述。
Percutaneous Endoscopic Lumbar Discectomy (PELD) technique belongs to minimally invasive technique with the advantages of minimal trauma, less bleeding, rapid postoperative recovery, fewer complications and little affection on the spine stability. It is originally used to treat lumbar discherniation, namely percutaneous endoscopic lumbar discectomy. Lumbardisc herniation is a common disease and most of them can be treated through conservative treatment to achieve clinical cure results. But if the conservative treatment is ineffective, the patients require operative treatment. However, traditional surgical treatment has the features of large trauma, more bleeding and slow postoperative recovery. With the development of minimally invasive techniques, spine surgeons pay much attention to Percutaneous Endoscopic Lumbar Discectomy (PELD) technique. Furthermore, the indications of this technique also extend stolumbar spine instability, discogenic low back pain, lumbar spinal stenosis and other diseases. This paper will summarize the development, anesthesia, indications and clinical efficacy of this technique.

Abstract: 介绍两类不同的浸入式边界方法及其对它的改进.然后采用均匀矩形交错网格和压力校正投影法,对不可压流场中的二维圆柱绕流进行了数值求解并对比了两类方法的精度.计算分析表明,连续显力法具有构造简单,适用性强的优点.但离散隐力法在物面边界精度上要优于前者.改进后,在二阶精度的离散格式下物面边界精度较低的显示力源法的精度有一定提高,同时发现,加密网格以提高数值精度的方法对于连续显力法并不总是有效.而同样格式下,离散隐力法具有更高精度,其中预测-校正离散隐力法可以在此基础上获得更小的计算误差和更快的收敛速度.数值解与文献已有的数值和实验结果吻合得很好,表明边界算法及其程序是可靠和有效的.
