Gaoya dianqi, 1999 一、前言在多年的SF6气体湿度监测中,我们发现设备内SF6气体湿度受运行环境温度影响很大,而GB/T8905—1996中SF6的湿度标准是20℃时的值,由于测试时环境温度往往不是20℃,有的甚至与20℃相差很大,这就给SF6电气设备的监督和验收带来了困难.为了解决这一问题,本文就设备中SF6气体湿度受运行环境温度影响的情况进行了分析.二、SF6电气设备中气体湿度与环境温度的关系在SF6电气设备中,固体有机绝缘材料、瓷套内壁、操作拉杆及吸附剂中均含有微量的水分,且与SF6气体中的水分存在着分配平衡 ...

Shuitu Baochi Xuebao, 1993 林地同样存在着土壤流失。林地土壤流失允许量的是维持水续利用土地生产力所允许的流失量。通过林地养分元素流失和积累、森林生长和森地地层土壤流失量实测，从土壤养分平衡及岩石成土速率分析，探讨森林地的土壤允许失量。认为在当地气候条件下，石灰岩发育土壤的林地其允许流失量上限为50t/km^2.a，非碳酸岩发育土壤的林地允许流失量上限100t/km^2.a人工集约经营森林，由于整地措施，土壤流失量会加大，此时应增施肥料以达到土壤肥力平衡。

Zhongshan Daxue xuebao. Yixue kexue ban, 2009 【目的】 探讨左旋精氨酸(l-Arg)对大鼠中期肺动脉高压(PH)的防治作用及机理。【方法】 将18只雄性SD大鼠随机分为3组,对照组(C组,n = 6)。PH组(M组,n = 6)。l-Arg + PH组(L组,n = 6)。于M组和L组用野百合碱(MCT)一次腹膜腔注射诱导PH模型,L组每天进行腹膜腔注射l-Arg。 21 d 后用右心导管法测定右心室收缩压(RVSP);用化学比色法检测血浆中一氧化氮(NO)水平;用Hydroethidine进行肺灌注测量肺组织氧自由基(O2。誗-)的产量。【结果】
