Gaoya dianqi, 2010 为了正确认识负离子在空气放电中的作用,计算了包含负离子的多组分漂移-扩散方程组,得到了随时间变化的电流密度、等离子体组分浓度、体积力密度,与无负离子的情况进行对比后发现放电中产生的负离子可加快放电起动速度,但使放电稳定性降低;它导致激励器放电功率降低,同时等离子体体积力的控制能力却得到增强;最后,负离子的存在延长了正离子寿命,可增强电离程度。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Gongye shui chuli, 1985 由于离子交换树脂对各种反离子的吸取具有选择性,所以当两种离子达到离子交换平衡时,它们在水溶液中的浓度比和在树脂相中的浓度比是不一样的。离子交换平衡就是研究平衡时这些离子浓度的关系。

Gongye shui chuli, 2015 采用超高石灰铝法向含氯废水中添加氧化钙和偏铝酸钠,使钙离子、铝离子与氯离子形成不溶性的沉淀,达到去除氯离子的目的。考察了时间、温度、氧化钙添加量、偏铝酸钠添加量对溶液中氯离子去除的影响,结果表明:超高石灰铝法可以有效去除氯离子,当温度为40℃,搅拌时间为40 min,n(Ca):n(Al):n(Cl)为5:3:1时,氯离子去除率达到80.05%,石化废水处理后的氯离子质量浓度为193 mg/L,达到回用水要求氯离子低于200 mg/L的标准。

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 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...
