常温与低温灌注下狗全肝血流阻断比较实验

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1990
为了探讨全肝血流阻断带来的生理生化改变,常温下全肝血流阻断的安全时限及低温灌注下对肝脏的保护作用,作者采用脾颈静脉分流减压门静脉系统方法,将21只狗随机分为3组:A组全肝血流阻断45分钟;B组1小时;C组在低温灌注下全肝血流阻断1小时,观察动物一般情况,生理生化及病理学改变和术后生存率。结果表明,常温下狗全肝血流阻断安全时限为45分钟;超过1小时,动物发生休克,生理、生化、病理改变显著,术后存活率仅28.5%;低温灌注可起到明显的对肝脏缺血的保护作用。

谈谈对直流输电主设备的试验和要求

open access: yesGaoya dianqi, 1979
根据实际工作经验,提出了对可控硅换流阀的试验要求,推荐了试验线路,介绍了实际试验中应注意的一些问题。最后还对可控硅阀。换流变压器、直流电抗器和调谐装置的技术要求,作了扼要讨论。 直流输电主设备,包括可控硅换流阀、换流变压器、直流电抗器、交流调谐装置等设备(注:避雷器根据绝缘配合提要求)。其中,可控硅换流阀与交流设备完全不同,且在投资和安全运行中都有重大影响,所以本文将重点谈谈可控硅换流阀的试验。对于其他设备,因与交流设备既有类同之处,又有独特之点,所以只讨论一下它们作为直流设备而引起的一些具体要求。
