1亚洲首个500kV可控串补(TCSC)工程(Ⅱ)——天广交流输变电平果变电站可控串补控制与保护系统设计方案显示文摘串联补偿广泛应用于增加高电压、长距离和大负荷送电系统的稳定性。电力电子技术的使用使串联补偿具有更大的灵活性与实用性,其优势可以从分2段布置的电容器组中看出来,其中可控串补(TCSC)和固定串补(FSC)设备均放在同一平台上。每段都使用一个独立的旁路断路器来分别将电容器组投入或退出(旁路)。《国际电力》在2004年第4期上介绍了西门子公司承接的中国天广平果站可控串补工程的一次系统设计,本期将介绍该工程的控制与保护系统设计方案。K Braun H Spachtholz M Beck 周彦 彭饱书 龚天森 2004国际电力2004,8,6:8
2Adult-to-adult right lobe living donor liver transplantation:Comparison of endoscopic retrograde cholangiography with standard T2-weighted magnetic resonance cholangiography for evaluation of donor biliary anatomy显示文摘AIM: To compare the value of endoscopic retrograde cholangiography (ERC) and standard T2-weighted magnetic resonance cholangiography (MRC) in the evaluation process as adult-to-adult right lobe living donor liver transplantation (LDLTx) demands a successful outcome, and exact knowledge of the biliary tree is implicated to avoid biliary complications, postoperatively.METHODS: After starting the LDLTx program, 18 liver transplant candidates were selected for LDLTx by a stepwise evaluation process. ERC and standard T2-weighted MRC were performed to evaluate the biliary system of the donor liver. The anatomical findings of ERC and MRC mapping were compared using the Ohkubo classification. RESULTS: ERC allowed mapping of the whole biliary system in 15/15 (100%) cases, including 14/15 (93.3%) with biliary variants while routine MRC was only accurate in 2/13 (15.4%) cases. MRC was limited in depicting the biliary system proximal of the hepatic bifurcation. Postoperative biliary complications occurred in 2 donors and 8 recipients. Biliary complications were associated with Ohkubo type C, E or G in 6/8 recipients, and 2/3 recipients with biliary leak received a graft with multiple (≥2) bile ducts. CONCLUSION: Pretransplant ERC is safe and superior over standard MRC for detection of biliary variations that occur with a high frequency. However, precise knowledge of biliary variants did not reduce the incidence of postoperative biliary complications.Perdita Wietzke-Braun Felix Braun Dieter Müller Thomas Lorf Burckhardt Ringe Giuliano Ramadori 2006World Journal of Gastroenterology2006,12,36:5
3Why Is the Climate Forcing of Sulfate Aerosols So Uncertain?显示文摘Sulfate aerosol particles have strong scattering effect on the solar radiation transfer which results in in- creasing the planet albedo and, hence, tend to cool the earth-atmosphere system, Also, aerosols can act as the cloud condensation nuclei (CCN) which tend to increase the albedo of clouds and cool the global warm- ing. The ARPEGE-Climat version 3 AGCM with FMR radiation scheme is used to estimate the direct and indirect radiative forcing of sulfate aerosols. For minimizing the uncertainties in assessing this kind of cool- ing effect, all kinds of factors are analyzed which have been mixed in the assessment process and may lead to the different results of the radiative forcing of aerosols, It is noticed that one of the uncertainties to assess the climate forcing of aerosols by GCM results from the different definition of radiative forcing that was used. In order to clarify this vague idea, the off-line case for considering no feedbacks and on-line case for including all the feedbacks have been used for assessment. The direct forcing of sulfate aerosols in off-line case is -0.57 W/ m2 and -0.38 W / m2 for the clear sky and all sky respectively. The value of on-line case appears to be a little larger than that in off-line case chiefly due to the feedback of clouds. The indirect forc- ing of sulfate aerosols in off line case is -1 .4 W / m2 and -1 .0 W / m2 in on-line case. The radiative forcing of sulfate aerosols has obvious regional characteristics. There is a larger negative radiative forcing over North America, Europe and East Asia. If the direct and indirect forcing are added together, it is enough to offset the positive radiative forcing induced by the greenhouse gases in these regions.Hu Rongming, Serge Planton, Michel Deque, Pascal Marquet and Alain Braun Centre national de recherches m t orologiques, Meteo-France 2001Advances in Atmospheric Sciences2001,18,6:2
