Dianci bileiqi, 1982 测量阀式避雷器电导电流,一般使用临时回路,其中包括整流管装置、滤波电容器、千伏表和微安表。在户外配电装置区域内搬运这些设备有一定的困难,也不方便,而且这种回路在工作时对工作人员也很危险。在我们企业里,研制了可移动的阀式避雷器电导电流测量装置,在颇大程度上消除了上述缺陷。

Shuitu Baochi Xuebao, 2020 河套灌区是我国最大的引黄灌区，区内水资源匮乏，农田防护林系统在灌区土壤水分调控中发挥着重要作用。为明确防护林对农田土壤水分的影响，采用传统统计学方法综合分析了防护林网内土壤蒸发、风速、光照强度、气温、空气相对湿度、细根生物量密度及土壤容重等因素对土壤含水量的影响。结果表明：不同配置的农田防护林网内田间土壤水分具有明显的空间异质性，水平方向上土壤含水量与林带距离呈正向关系，主要影响因子为风速、土壤蒸发和1H（H为防护林树高）范围内的细根生物量密度；垂直方向上0—80 cm土壤水分从表层向下逐渐增加 ...
