Sodium gluconate(SG)is reported as an electrolyte additive for rechargeable aqueous zinc *** SG addition is proposed to modulate the nucleation overpotential and plating behaviors of Zn by forming a shielding buffer layer because of the adsorption priority and large steric hindrance effect,which contributes to limited rampant Zn^(2+)diffusion and mitigated hydrogen evolution and *** the introduction of 30 mmol/L SG in 2 mol/L ZnSO_(4)electrolyte,the Zn anode harvests a reversible cycling of 1200 h at 5 mA/cm^(2)and a high average Coulombic efficiency of Zn plating/stripping(99.6%).Full cells coupling Zn anode with V_(2)O_(5)·1.6H_(2)O or polyaniline cathode far surpass the SG additivefree batteries in terms of cycle stability and rate *** work provides an inspiration for design of a high-effective and low-cost electrolyte additive towards Zn-based energy storage devices.

为明确黄土高原不同耕作措施(覆盖种植、秸秆还田、深松耕和免耕)对春玉米氮肥偏生产力(PFP_(N))的影响,探究不同耕作措施下驱动春玉米PFP_(N)变化的因素,本研究采用Meta分析、回归分析和随机森林相结合的方法,以传统耕作措施(裸地种植、无秸秆还田和犁耕)为对照,分析了春玉米PFP_(N)在不同耕作措施下的变化特征。结果表明:与传统耕作措施相比,覆盖、秸秆还田和深松耕分别使春玉米PFP_(N)提高38.8%、10.3%和8.4%,而免耕对春玉米PFP_(N)无显著影响。随机森林模型表明:在覆盖和秸秆还田措施下,年均降雨量和生育期降雨量是影响春玉米PFP_(N)的两个重要因素;在深松耕措施下,年均降雨量和持续时间是影响春玉米PFP_(N)的两个重要因素。亚组与回归分析表明:在年均降雨量≤400 mm、生育期降雨量≤300 mm或年均温度<7℃的区域,覆盖可以使春玉米PFP_(N)提高77.7%~99.5%,且覆盖措施对春玉米PFP_(N)的提高效果与年均降雨量、生育期降雨量和年均温度呈负相关;在年均降雨量400~500 mm或生育期降雨量300~400 mm的条件下,秸秆还田使春玉米PFP_(N)提高10.2%~16.3%;在年均降雨量400~500 mm,深松耕试验持续时间<3 a时,春玉米PFP_(N)可提高14.1%~14.6%。因此,依据区域和气候特征,采用适宜的耕作措施可以进一步提高春玉米PFP_(N),促进旱区作物可持续生产目标的实现。本研究可为提高黄土高原春玉米PFP_(N)以及制定区域可持续发展的农业生产策略提供参考。

脾乃后天之本、气血生化之源,脾之阳气为脾脏功能的发挥提供了“动力”,而脾阴则提供了“物质基础”。脾阴学说成说较晚、论说较少,基于文献研究系统梳理了脾阴理论内涵及历史发展源流,认为“辅运化”“主滋养”和“和胃阳”是脾阴主要的生理功能;脾阴理论的发展主要经历了《黄帝内经》构建脏腑阴阳理论体系、《伤寒论》初识脾阴方证、“丹溪学派”首开滋阴法先河、缪希雍系统建立脾阴理论体系、吴澄引申“芳香甘平”治法5个历史时期。此外,通过文献计量学Citespace分析脾阴学说现代整体发展应用情况,对比古今常用11个滋补脾阴类中药复方发现:现代研究中对脾阴学说的认识主要传承自唐容川、叶天士、吴澄、李东垣、缪希雍、张锡纯几位医家;其理论主要应用在消渴(糖尿病)、泄泻、便秘、肉痿等疾病治疗中;用药偏以甘淡,兼顾养胃阴为特色;局方参苓白术散成方早,充分体现了“甘淡”补脾之滋补脾阴用药的基本法则,具有健脾气、滋脾阴、渗脾湿之功效,全方升降相因、散收并用、补行兼施,尤宜于脾气阴虚夹湿的患者,乃滋补脾阴理论应用的基础方。

【目的】单半乳糖甘油二酯合酶(MGD)是合成单半乳糖甘油二酯(MGDG)的关键酶,在植物响应低磷胁迫过程中起着重要作用。为系统了解水稻OsMGD2和OsMGD3基因在低磷胁迫响应中的作用和功能。【方法】用盆栽试验分析正常和低磷条件下野生型(SR1)、过表达OsMGD2和OsMGD3转基因烟草的生理响应及脂质组分的变化。【结果】无论在正常还是低磷条件下,转基因与野生型烟草的磷含量无显著差异,但转基因烟草的生物量、叶绿素含量和光合能力均显著高于野生型。转基因烟草在低磷胁迫下的磷脂(PL)含量、双半乳糖甘油二酯(DGDG)含量、DGDG与MGDG的比值和半乳糖脂(GL)与PL的比值均显著高于野生型烟草,且OsMGD3转基因烟草的脂质含量和比值均高于OsMGD2转基因烟草。【结论】通过调控水稻OsMGD2/3基因表达,可提高植物低磷下的膜脂重塑能力,进而维持植物在低磷胁迫下较高的光合和生长能力,增加植物的低磷耐受性。
