Nitrogen Anchoring Effect Triggering Improved Reversible Hydrogen Storage of Mg(BH4)2
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT This research uncovered the influence of nitrogen‐doped MXene Ti3CN on the reversible hydrogen storage properties of Mg(BH4)2. The Mg(BH4)2‐20Ti3CN composite began releasing hydrogen at a temperature of 80°C. In addition, the composite discharged over 8.8 wt% hydrogen at a comparatively lower temperature of 270°C, whereas the pure Mg(BH4)2 ...

An AC constant current power supply design based on linearity power amplifier [PDF]
, 2008 交流恒流源作为稳定电源的分支有广泛用途，其作为一项技术在电源的研究领域中有很重要的意义。其发展与科技的进步息息相关，在各个国家特别是发达国家的国民经济中占有十分重要的地位。近年来我国检测技术有了较大的提高，但同发达国家的电网检测技术相比，差距仍然很大，存在参数检测精度不高、抗干扰性较差,实时性比较差、电路设计复杂等缺点。针对这些问题，本课题建立了一个以AT89C51单片机为控制核心的恒流源控制系统，该系统具有速度快、精度高、实用性强、电路模块化等特点。 本课题已经顺利完成以下几部分内容： 1硬件控制系统：

Gaoya dianqi, 2018 高耦合电抗器（HCSR）辅助开断并联灭弧室是解决大电流故障开断的一种有效方法。由于SF6电弧自身的负伏安特性会影响并联支路电流的同时过零,增加了开断并联SF6电弧支路的难度,限制了其在高电压领域的应用。结合高耦合电抗器辅助并联支路开断的设计思想,首先利用40.5 kV断路器两柱相同灭弧室,进行了小电流条件下,SF6电弧并联支路开断的试验研究,重点分析了开断电流大小、燃弧时间长短与均流、限流开断特性间的关系。其次,针对80 kA大电流条件下的并联支路开断特性,进行了单分试验的初步研究和验证。结果表明 ...

A method of CNC handwheel connection based on serial communication [PDF]
, 2010 为了解决总线模式数控系统中手轮信号采集、传输难的问题,采用了一种新型的手轮连接方式,即通过工业计算机现有的串口读取手轮的脉冲信号,经特定程序识别处理后,交由数控系统内核以完成相应的运动控制。实验结果表明,利用串口实现手轮连接,不仅能够达到传统连接方式下手轮工作的全部性能指标,而且能减少硬件数量,降低系统成本,简化系统结构,有利于进一步提高系统的可靠性。Aiming at the difficulty of handwheel's signal collection and transmission in
