Zhongshan Daxue xuebao. Yixue kexue ban, 1991 伤害性刺激猫的腓浅神经诱发体感皮层痛敏细胞放电的非时锁反应(N—TLR)表现为放电间隔变小,电针抑制此反应,使间隔变大,而伤害性刺激诱发的时锁反应(TLR)表现为前一后峰型反应,电针主要抑制后峰.表明N-TLR可以反映总的电针效应,而TLR则反映电针效应的更主要部分,提示观察电针效应不仅要用N-TLR,还要用TLR,后者更为重要.

Dianci bileiqi, 2021 柔性石墨复合接地体是一种具有良好的导电性、耐腐蚀性且非铁磁性的非金属接地体。为研究电感效应与火花放电效应对石墨复合接地体冲击特性的影响规律,笔者搭建了频域电网络模型及其迭代算法对接地体的冲击接地特性进行仿真计算,通过与CDEGS仿真结果及文献的试验结果进行对比,验证了仿真计算方法的有效性及准确性。在此基础上,对不同土壤和雷电流参数下石墨复合接地体的冲击特性进行仿真计算。研究结果表明:高土壤电阻率作用下,石墨复合接地体的冲击系数较小,火花放电效应较强,相反的,当土壤电阻率较低时,电感效应较强 ...

Gongye shui chuli, 2016 通过分析电磁感应水处理器的工作原理和影响水处理效果的关键因素,建立了决定除垢效率的溶液感生电流和磁感应强度的解析模型。针对感生电流对溶液做功的平均功率与激磁信号的函数关系,提出了一种将双极性脉冲馈入LC电路产生谐振的优化方法,采用自动频率跟踪技术对其脉冲的输出频率进行实时调整,从而保证谐振电路输出最优频率的激磁信号,以提高电磁感应水处理器的处理效果。实验结果表明:该水处理器可以更有效地提高除垢效率,且对环境的适应能力更强。
