He jishu超声分子束注入是磁约束聚变装置常用的补充加料手段之一，并对等离子体流和湍流产生重要影响。实验在J-TEXT装置上开展，采用三台阶朗缪尔探针阵列，在欧姆放电氢等离子体中观测了超声分子束注入对边缘流和湍流的影响。结果表明：超声分子束注入后测地声模带状流、湍流及其驱动的粒子输运分别减小40%~60%、50%~70%及60%~70%，且伴随着离子-离子碰撞频率增大；湍流雷诺协强及湍流对测地声模带状流做功明显减小；密度及温度梯度降低。进一步分析表明，测地声模带状流减弱主要归因于湍流雷诺功的降低和碰撞率的增加 ...

Gaoya dianqi, 2017 溶液中微弧等离子体是气体等离子体在溶液中的发展和应用,文中综述了溶液中微弧等离子体在材料表面处理的研究进展。溶液中微弧等离子体在阳极表面可发生微弧氧化、纳米尺度的抛光研磨、纳米尺度重构、纳米颗粒的制备;在阴极表面可发生微弧等离子体化学热处理、微弧等离子体镀膜、表面功能膜层的制备。该技术通过调控辉光向弧光过渡的非稳态大电流和高电压区间达到辉光的聚缩和弧光的弥散,形成微弧等离子体,发挥辉光和弧光各自在材料表面的优势,实现了材料的表面处理。该技术的发展对材料的处理提供了新的方法。

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...

Gaoya dianqi, 2009 电流体动力(EHD)等离子体发生器产生的常压等离子体可以在不存在机械活动部件的条件下把电能转化为空气的动能,在气流控制领域具有巨大的发展前景。但是目前EHD等离子体发生器的能量转化效率仍然很低。笔者通过实验探讨了利用Kapton将低电极进行封装对EHD等离子体发生器产生的影响。实验表明,低电极进行封装后低电极附近及电压周期负半周内的等离子体的产生被有效抑制,等离子体发生器产生的气流速度增加,能量转化效率得到显著提高。

Gaoya dianqi, 2018 由于SF6气体温室效应显著,CO2气体作为目前具有潜力环保型SF6替代气体之一,以CO2气体作为绝缘和灭弧介质的断路器已经得到应用。实际上,喷口材料烧蚀将导致PTFE蒸汽作为杂质影响电弧等离子体的物性参数从而影响断路器的开断性能。为了建立物理模型研究和优化断路器开断性能,必须首先确定电弧等离子体物性参数。因此文中研究了0.6 MPa下温度区间为300～30 000 K时的CO2-PTFE电弧等离子体物性参数。首先基于最小Gibbs自由能法确定了电弧等弧等离子体粒子组分 ...
