摘要：背景知识一直是各类译者能力模型中重要的组成模块。译者在大数据时代并不缺乏信息查证工具,但面对专业要求较高的专利文献翻译,查证得来的碎片化信息难以形成体系,无法帮助译者克服翻译难题。文章提出了一种新的教学模式:基于现有专利翻译人才培养模式,聚焦个人知识管理理论,并结合信息时代的翻译技术,提出PKM教学法,以期帮助译者在翻译过程中高效、合理地获取和内化背景知识。

摘要：角度变位２Ｋ－Ｈ行星齿轮的优化设计是一个多峰函数优化问题，用传统确定性的、计算式方法容易陷入局部最优解．为达到全局优化的目的，采用实值编码遗传算法进行优化．首先给出了一个通用性强、以体积最小为优化目标的２Ｋ－Ｈ传动机构的优化模型，然后描述一种实值编码遗传算法的实现，并将之应用于角度变位行星传动的优化设计．其优化结果与单纯形的比较表明，遗传算法更能脱离局部解而取得更优解，在工程设计中具有一定的应用价值．

摘要：AIM: To evaluate the biological functions of tissue-engineered human corneal epithelium (TE-HCEP) by corneal transplantation in limbal stem cell deficiency (LSCD) rabbit models. METHODS: TE-HCEPs were reconstructed with DiI-labeled untransfected HCEP cells and denuded amniotic membrane (dAM) in air-liquid interface culture, and their morphology and structure were characterized by hematoxylin-eosin (HE) staining of paraffin-sections, immunohistochemistry and electron microscopy. LSCD models were established by mechanical and alcohol treatment of the left eyes of New Zealand white rabbits, and their eyes were transplanted with TE-HCEPs with dAM surface outside by lamellar keratoplasty (LKP). Corneal transparency, neovascularization, thickness, and epithelial integrality of both traumatic and post transplantation eyes were checked once a week by slit-lamp corneal microscopy, a corneal pachymeter, and periodic acid-Schiff (PAS) staining. At day 120 post surgery, the rabbits in each group were sacrificed and their corneas were examined by DiI label observation, HE staining, immunohistochemistry and electron microscopy. RESULTS: After cultured for 5 days on dAM, HCEP cells, maintaining keratin 3 expression, reconstructed a 6-7 layer TE-HCEP with normal morphology and structure. The traumatic rabbit corneas, entirely opaque, conjunctivalized and with invaded blood vessels, were used as LSCD models for TE-HCEP transplantation. After transplantation, obvious edema was not found in TE-HCEP-transplanted corneas which became more and more transparent, the invaded blood vessels reduced gradually throughout the monitoring period. The corneas decreased to normal thickness on day 25, while those of dAM eyes were over 575 mu m in thickness during the monitoring period. A 45 layer of epithelium consisting of TE-HCEP originated cells attached tightly to the anterior surface of stroma was reconstructed 120 days after TE-HCEP transplantation, which was similar to the normal control eye

摘要：原油脱盐、脱水是石油工业中不可缺少的环节。我国开采的原油以石蜡基高蜡原油居多,石蜡基高蜡原油具有含蜡高、黏度大、凝点高和低温流动性差等特点,形成的原油乳状液异常稳定,破乳难度极大。在石蜡基原油体系中添加乙酸钠,可以增加体系对微波的吸收能力,加大油、水密度差,进而提高微波辐射处理的脱水率。采用正交实验设计法,研究了乙酸钠存在下大庆石蜡基高蜡原油的微波辐射破乳规律。结果表明,添加极少量的乙酸钠就能显著提高石蜡基高蜡原油乳状液的破乳效果。利用SH9402微波反应系统,在微波功率225W、系统压力0.7MPa、恒压时间12min、剂/油质量比0.05的条件下,含水质量分数50%的大庆石蜡基高蜡原油乳状液脱水率可达95.83%。

摘要：高压IGBT串联是提高大容量变换器电压等级和容量的有效手段之一,但器件串联带来的复杂机械结构为母排设计与杂散参数建模分析带来巨大的困难,常规的部分单元等效电路(PEEC)方法直接用于该领域难以保证准确性。该文提出了一种应用于提取大尺寸复杂结构母排杂散参数的改进的PEEC方法和结构设计准则,采用分块计算方式建立了母排杂散参数模型。在实际的4.5kV/600A高压IGBT串联试验平台上进行了系列高压大电流试验,在剔除换流二极管正向特性影响的条件下,对比实验和仿真结果分析了母排杂散参数对器件暂态的影响,证明了该方法的准确性与实用性。该设计方法降低了杂散参数,提升了变换器运行的可靠性,并为主动控制创造了有利条件。

摘要：本文针对一类具有时变输出约束链式非完整系统的预设时间镇定问题,首先通过tan型障碍Lyapunov函数处理系统输出约束,然后基于所给的新型切换时变函数,直接应用于虚拟(实际)控制器设计,提出了系统状态反馈镇定的非缩放变换设计方案.本文所设计的控制器使得闭环系统状态不违反约束的同时,可在任意给定的有限时间内收敛到零点.与传统的基于缩放变换设计相比,本文所提出的控制策略既有效解决了控制器的计算奇异性问题,又减少了关于时变缩放函数的计算,使控制器设计更为简单.最后,通过仿真结果验证了所提设方法的有效性.
