Dianci bileiqi, 1988 详细分析了目前国内外采用的加速老化试验方法中存在的问题。指出试验电压与参考电压成正比的观点是错误的。文中统计了国内外氧化锌阀片的参考电压和阀片的电容,表明阀片的参考电压和电容都存在一定的分散性。加速老化试验电压应考虑电容分散性引起的试验电压升高,试品应选择不同参考电压的阀片。并提出了加速老化试验的试品选择和试验电压的推荐方法。

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1926-1939, November 2024.Abstract Simulation studies are essential tools to assess statistical methods. Functioning as controlled experiments, simulations generate data from known underlying processes. However, unclear or incomplete reporting of simulation studies can impact their interpretability and reproducibility, potentially leading to the misuse of statistical methods ...

Dianci bileiqi, 2011 金属氧化物避雷器（MOA）是电力系统中不可或缺的设备,为了保证电网的安全稳定运行,应定期对其进行预防性试验。简要介绍了MOA试验项目及其影响因素,着重讲述了试验设备对试验结果的影响。直流高压发生器加装限流电阻后,MOA的参考电压和泄漏电流都较实际值偏大。鉴于此,提出了现场试验时去除限流电阻影响的方法,并给出了推导公式。

Audience segmentation approach to conservation messaging for transforming the exotic pet trade
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Advancing transformative change for sustainability requires population‐wide behavior change. Yet, many behavioral interventions tackling environmental problems only examine average effects on the aggregate, overlooking the heterogeneous effects in a population.
