微通道沸腾不稳定性降低设备运行性能及传热特性。设计入口集成种子汽泡发生器的三角形硅基微通道热沉。搭建同步光学可视化测量实验台。研究加热膜长度、质量流量及种子汽泡触发频率对微通道内沸腾不稳定性及传热影响。结果表明:加热膜长度和质量流量作为控制沸腾不稳定性的关键参数,加热膜长度越长或质量流量越低,沸腾起始点和临界热流密度越早发生。单相液体区域,热流密度增大,压降略微降低,温度线性升高。汽液两相区域,热流密度增大,压降迅速增大,温度呈指数式上升。触发种子汽泡作为一种主动式控制技术,沸腾不稳定性得到抑制或消除,换热得到显著增强,是一种值得推广的技术。

本文通过MEMS技术设计并加工出一种间断型波纹微通道。采用丙酮为工质,借助高速同步测量系统对间断型波纹微通道内的流动沸腾换热特性进行了实验研究。通过与传统的矩形直通道对比,分析了两种微通道的流型、换热系数和底面温度分布。实验结果表明:间断型波纹微通道的出口处能维持稳定的环状流,有效推迟了局部干涸。由于特殊的壁面结构能提升沸腾换热性能,所以间断型波纹微通道的换热系数要高于矩形直通道,增幅接近70%。相同工况下,间断型波纹微通道底面温差更小,提供了更好的温度分布均匀性。

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

由于CFCs和HCFCs人工合成制冷剂破坏大气臭氧层,并产生温室效应,因此用自然工质替代合成工质越来越受到国内外制冷界的重视。文章对环保型CO2制冷工质进行了综合评价,并利用热力学原理建立模型,分析了CO2跨临界带膨胀机制冷循环的性能。结果表明:与CO2跨临界带节流阀制冷循环相比,CO2跨临界带膨胀机制冷循环明显提高了系统的性能系数(COP)。同时在保持压缩机排气压力和膨胀机等熵效率一定时,CO2跨临界带膨胀机制冷循环系统COP随着气体冷却器出口温度的增加而逐渐降低,但随着蒸发温度的增加而快速增加。在实际系统设计过程中,应综合考虑以上影响因素,以使系统设计最优化。

AIM： To evaluate the effect of intravitreal ranibizumab injection for retinopathy of prematurity（ROP） in Zone Ⅱ Stage 3^＋.METHODS： Data was collected for ROP patients with Zone Ⅱ Stage 3^＋ who received intravitreal ranibizumab injections between October 2014 and Janu ary 2017 at the Department of Ophthalmology in our hospital. No prior laser or other intravitreal treatment was done. Prior to the intervention and at each follow-up visit, fundus examination was performed. Gestational age at birth, sex, birth weight, ROP zone, ROP stage, post menstrual age（PMA） at treatment, and follow-up pe riod were recorded. The final clinical status of the retina was evaluated for each patient. The primary outcome mea sures included ROP recurrences requiring re-treatment, complete or incomplete peripheral ***： Eighty-six eyes of 46 premature infants with Zone Ⅱ Stage 3~＋ ROP were enrolled in the study. The mean gestational age at birth was 28.18±1.67（range： 25 to 33）wk and the mean birth weight was 1070.57±226.85（range： 720.00 to 1650.00） g. The mean PMA at treatment was 38.32±2.99（range： 32.29 to 46.00）wk. Seventy-one eyes（82.56%） were treated success fully with intravitreal ranibizumab as monotherapy. Fifteen eyes（17.44%） developed recurrent disease. The mean interval between the treatment and retreatment was 5.96±3.22（range： 1.86 to 11.71）wk. All eyes vascularized into zone Ⅲ at the end of the study and among them 62 eyes（72.09%） achieved complete vascu ***： Intravitreal ranibizumab injection is an effective treatment in Zone Ⅱ Stage 3^＋ ROP patients. More patients with longer follow-up duration are necessary to confirm the safety and efficacy of this treatment.
