1混合双极高压直流输电系统的特性研究显示文摘为了充分发挥电网换相换流器高压直流输电系统(line commutated converter based high voltage direct current,LCC-HVDC)和电压源换流器高压直流输电系统(voltagesource converter based HVDC,VSC-HVDC)的优势,针对一种新型的混合双极高压直流输电系统(hybrid bipolar basedhigh voltage direct current,HB-HVDC)进行了研究,该系统的正极是传统的12脉动LCC-HVDC系统,而负极是VSC-HVDC系统。建立了由LCC正极和VSC负极组成的混合双极高压直流输电系统的模型,推导了其在稳态时的数学模型,并设计了正负极之间的协调控制策略。在PSCAD/EMTDC环境下对HB-HVDC系统的稳态和暂态运行特性进行了研究分析。最后对HB-HVDC系统和闭锁负极VSC-HVDC后LCC-HVDC系统的运行特性进行了对比研究。结果表明:HB-HVDC系统可以更好地调节交流母线电压,减少LCC极换相失败的可能性,并且具有快速的故障恢复能力;同时也证明所设计的协调控制策略可以有效地改善HB-HVDC系统的稳态和动态特性。郭春义 赵成勇 Allan Montanari Aniruddha M.Gole 肖湘宁 2012中国电机工程学报2012,32,10:60
2高压直流局部放电的试验研究及其放电源识别策略显示文摘在长期高压直流电压作用下,电气设备的绝缘不可避免地逐渐老化,有必要对其绝缘状态进行监测。由于不同性质的绝缘缺陷对电气设备的损害程度不同,因而缺陷的识别是非常重要的。为此,搭建了基于交流局放检测设备的直流局部放电检测系统,对3种典型的直流放电(电晕、沿面、内部放电)进行了试验研究,建立了典型放电的数据库,给出了试验结果。并基于局部放电信号之间的相关性统计特性,试图通过对各种参数的分析,寻求区别不同放电现象(电晕、沿面、内部放电)的特性参数,对直流电压作用下的放电源进行识别。研究表明,直流电压作用下,将电晕放电从沿面放电和内部放电中分离出来相对来说难度小一些;而单靠现有的局部放电的统计分析将内部放电从沿面放电中分离出来是很难的,需要进一步寻找两种放电的新的特性参数。牛海清 陈小林 A.

4Prophylaxis for venous thromboembolism after resection of hepatocellular carcinoma on cirrhosis: Is it necessary?显示文摘AIM: To assess the safety and effectiveness of prophylaxis for venous thromboembolism (VTE) in a large population of patients with hepatocellular carcinoma (HCC) on cirrhosis.METHODS: Two hundred and twenty nine consecutive cirrhotic patients with HCC who underwent hepatic resection were retrospectively evaluated to assess whether there was any difference in the incidence of thrombotic or hemorrhagic complications between those who received and those who did not receive prophylaxis with low-molecular weight heparin.Differences and possible effects of the following parameters were investigated: age,sex,Child-Pugh and model for end-stage liver disease (MELD) score,platelet count,presence of esophageal varices,type of hepatic resection,duration of surgery,intraoperative transfusion of blood and fresh frozen plasma (FFP),body mass index,diabetes and previous cardiovascular disease.RESULTS: One hundred and fifty seven of 229 (68.5%) patients received antithromboembolic prophylaxis (group A) while the remaining 72 (31.5%) patients did not (group B).Patients in group B had higher Child-Pugh and MELD scores,lower platelet counts,a higher prevalence of esophageal varices and higher requirements for intraoperative transfusion of FFP.The incidence of VTE and postoperative hemorrhage was 0.63% and 3.18% in group A and 1.38% and 1.38% in group B,respectively;these differences were not significant.None of the variables analyzed including prophylaxis proved to be risk factors for VTE,and only the presence of esophageal varices was associated with an increased risk of bleeding.CONCLUSION: Prophylaxis is safe in cirrhotic patients without esophageal varices;the real need for prophylaxis should be better assessed.Marco Vivarelli Matteo Zanello Chiara Zanfi Alessandro Cucchetti Matteo Ravaioli Massimo Del Gaudio Matteo Cescon Augusto Lauro Eva Montanari Gian Luca Grazi Antonio Daniele Pinna 2010World Journal of Gastroenterology2010,16,17:6
5Heavy cigarette smoking and alcohol consumption are associated with impaired sperm parameters in primary infertile men显示文摘We assessed the concomitant impact of cigarette smoking and alcohol con sumption in men presenting for primary couple's infertility.Data from 189 in fertile men were an a lyzed.Semen analysis,serum hormones,and sperm DNA fragmentation(SDF)were obtained.Smoking status was categorized as follows:current nonsmoker(-S),moderate smoker(+MS),and heavy smoker(+HS).Alcohol consumption was categorized as follows:abstainer(-D),moderate drinker(+MD),and heavy drinker(+HD).Descriptive statistics and logistic regression models were applied.Among all the participants,132(69.8%),30(15.9%),and 27(14.3%)patients were-S,+MS,and+HS,respectively.In addition,67(35.4%),77(40.7%)and 45(23.8%)men were-D,+MD and+HD,respectively.Regarding concomitant habits,52(27.5%)patients were nonsmokers and abstainers(-S/-D:Group 1),91(48.1%)had at least one recreational habit(-S/+D or+S/-D:Group 2),and 46(24.3%)were both smokers and drinkers(+S/+D:Group 3).Sperm concentration and progressive motility were lower in+HS and+HD,compared with-S and-D(all P<0.05),respectively.Similarly,both parameters were significantly lower in Group 3 than Groups 1 and 2(all P<0.05).SDF values were higher in Group 3 than Groups 1 and 2(both P<0.05).In multivariate analysis,follicle-stimulating hormone(FSH)levels and concomitant+S/+D status were independent predictors of impaired sperm concentration and progressive motility(all P<0.05).Heavy smoking and heavy drinking were associated with worse seminal parameters than moderate smoking/drinking and nonsmoking/abstaining.When concomitant,+S/+D status has an even greater detrimental effect on semen parameters.Luca Boeri Paolo Capogrosso Eugenio Ventimiglia Filippo Pederzoli Walter Cazzaniga Francesco Chierigo Federico Deho Emanuele Montanari Francesco Montorsi Andrea Salonia 2019Asian Journal of Andrology2019,21,5:6
6Semen analysis in chronic bacterial prostatitis: diagnostic and therapeutic implications显示文摘意义和在长期的细菌的前列腺炎的精液分析的诊断价值广泛地被辩论了并且仍然保持争论。在前列腺炎病人的细菌学的 workup 调查精液文化的诊断关联,我们回顾地分析了 696 个征兆的病人的一个临床的数据库。所有病人习惯性地受到四眼镜的测试,由精液文化和分析列在后面。这允许从数据库把,并且把三种不同诊断情形测试的“二眼镜”的 pre-/post- 按摩和标准“四眼镜”的测试与“五眼镜”的测试(四眼镜的正 post-VB3 精液文化) 作比较。“五眼镜”的测试在相对敏感和更小的减小显示出 3.6 褶层或 6.5 褶层增加(在为传统的 uropathogens (TU ) 的相对特性的 -13.2% 或 -14.7%) 与四眼镜或二眼镜的测试相比分别地。在 ROC 曲线和 Jouden 下面的区域是索引而积极、否定的可能性的比率比比较仪低,被增加,显示“五眼镜”的试金可能在证实两标准测试的否定结果是优异的。五 -- ,四 -- ,并且二眼镜的测试检测了 TU (Enterobacteriaceae, Enterococci,等等) 在在 130, 56,和 45 个病人的 120, 33,和 20 个病人和不平常的病原体(Streptococci,另外的克积极的种类, Mycoplasmata,和其它) 分别地。当病人们受到药理学治疗时,包括 fluoroquinolone 和 macrolide 的联合,处于根除率的差别都没在与不同测试诊断的组之间被观察,不管病原体范畴。根除与长期的症状 / 症状宽恕被联系;在症状 / 症状分数的重要团体之间的差别都没在整个一个 24 月的离开治疗后续时期被观察。在结论,我们的数据当这测试被用来补充四眼镜的 Meares 和 Stamey 测试时,在前列腺炎病人的诊断 workup 支持精液分析的实用性。microbiological 试金的改进传送重要诊断、治疗学的含意。Vittorio Magri Florian M.

7Pulse width modulation voltage source deadtime effect on partial discharge and lifetime of inverter‐fed motor insulation显示文摘This paper analyses the impact of square wave pulse voltage deadtime on the partial discharge(PD)and the lifetime of turn-to-turn insulation.A bipolar repetitive pulse voltage with a deadtime of 0–10μs is produced using double half-bridge solid-state switches having push–pull technology controlled by a field-programmable gate array.The mechanism of the discharge process at rising and falling edges of the pulse voltage before and after deadtime is analysed in detail.The discharge amplitude and PD probability at the rising/falling edges of the voltage waveform increase as the deadtime increases from 0 to 10μs due to the remanent charges.The number of PD and their intensity is higher at the first rising/falling edges of pulse voltage as compared to the second rising/falling edges for all deadtimes 0–10μs.As the deadtime increases beyond 2μs,the number of PDs increases and concentrates at a specific phase angle of rising/falling edges.These localise discharges degrade the insulation material and reduce its lifetime.This study helps to identify the inverter-fed motor insulation faults due to deadtime.It can provide guidelines to motor insulation designers to determine the limit value of deadtime to compensate PD and ensure the safer operation of such motors.Shakeel Akram Peng Wang Pengfei Meng Gian Carlo Montanari Farhan Hameed Malik 2022High Voltage2022,7,6:2
