Dianci bileiqi, 2020 超高压电网多采用同塔双回或多回线路,由于杆塔较高,遭受雷击时可能造成多回线路闪络。依托某换流站500 kV交流侧系统,利用EMTP/ATP建立电站雷电侵入波过电压计算模型,研究换流站交流侧同塔双回线路遭受雷击时站内设备上过电压特性以及与单回线路的区别。结果表明:雷击同塔双回线路杆塔时,在两回线路均闪络的情况下,换流站设备上反击侵入波过电压在双线运行方式下幅值远高于单线运行方式,且过电压最大值一般是在雷击进线段第二基杆塔TW2时出现,反击过电压特性与雷击单回线路差异较大 ...

Development and Psychometric Validation of the Chinese Online Disinhibition Scale for Adolescents
PsyCh Journal, Volume 15, Issue 4, August 2026.ABSTRACT Online disinhibition significantly influences adolescents' communication and behaviors in digital environments, yet culturally adapted measurement tools remain limited in China. This study aimed to develop and validate a Chinese version of the Online Disinhibition Scale (ODS‐C) based on Suler's (2004) theoretical framework.

Dianci bileiqi, 2016 在以往的接地参数计算中,直接将站内和站外不对称短路时的最大入地短路电流从接地网边角注入来计算各个接地参数,而忽略了短路过程中形成的回流电流和分流电流,这造成某些接地参数计算误差较大。本文以某电站的短路电流分布为例,计算分析了回流电流和分流电流对接地参数计算的影响,并研究了在计及回流电流和分流电流的情况下各个敏感因素对接地参数的影响。研究表明:计及回流电流和分流电流后,GPR会增大一定的幅度,但电位梯度和网内电位差相比只考虑入地短路电流时会增大很多,地表电位不均衡程度大大增大,接触电势和跨步电势也相应增大。

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Gongye shui chuli, 2015 研究了回流次数对间歇厌氧-好氧反应器处理效果的影响。结果表明,回流对硝化过程没有明显影响,3种条件下NH4+-N去除率均能达98%以上。而在回流次数较少的情况下,反硝化过程易受进水负荷的影响。增加回流次数有利于反硝化电子受体(NO3--N)的转移,并充分利用进水中的有机物进行反硝化过程,提高脱氮率。同时,反硝化速率也随回流次数的增加而增加。
