目的研究负离子处理时长对菠菜(Spinacia oleracea L.)贮藏品质的影响。方法本实验利用负离子发生器使之在密闭空间中产生负离子,用于菠菜贮藏前的预处理,通过测定贮藏期间菠菜的菌落总数、呼吸速率、质量损失率、色差(ΔE)、丙二醛、总酚含量等品质指标,研究了4种处理时长(0、30、60和90 min)对菠菜贮藏品质的影响。结果负离子处理能抑制菠菜表面微生物的生长,降低微生物对机体造成的侵害,延缓其氧化衰老,同时降低了菠菜呼吸速率,减少营养物质的消耗和叶绿素的分解,并维持较低的质量损失,随着负离子处理时长的增加,对菠菜贮藏过程中的品质保护效果越明显,负离子预处理90 min对菠菜的贮藏品质维护效果最好。可直观体现在菠菜的外观的变化以及色泽的维持。结论负离子合适的处理时长可以有效延长菠菜的货架期,为负离子预处理应用于果蔬保鲜提供了重要依据。

A new thermal protection design method for hypersonic vehicle's leading edge is proposed, which can effectively reduce temperature of the leading edge without additional cooling measures. This method reduces the leading-edge's temperature by the multi-scale collaborative design of the macroscopic thermal optimization and the mesoscopic woven structures of Three-dimensional Orthogonal Woven Ceramic Matrix Composites(TOCMC). The macroscopic thermal optimization is achieved by designing different mesoscopic woven structures in different regions to create combined heat transfer channels to dredge the heat. The combined heat transfer channel is macroscopically represented by the anisotropic thermal conductivity of TOCMC. The thermal optimization multiple linear regression model is established to optimize the heat transport channel, which predicts Theoretical Optimal Thermal Conductivity Configuration(TOTCC) in different regions to achieve the lowest leading-edge temperature. The function-oriented mesostructure design method is invented to design the corresponding mesostructure of TOCMC according to the TOTCC, which consists of universal thermal conductivity prediction formulas for TOCMC. These universal formulas are firstly derived based on the thermal resistance network method, which is verified by experiments with an error of 6.25%. The results show that the collaborative design method can effectively reduce the leading edge temperature by about 12.8% without adding cooling measures.

Solar-driven interfacial evaporation is a promising technology for freshwater production from seawater,but salt accumulation on the evaporator surface hinders its performance and *** this study,we report a simple and green strategy to fabricate a three-dimensional porous graphene spiral roll(3GSR)that enables highly efficient solar evaporation,salt collection,and water production from near-saturated brine with zero liquid discharge(ZLD).The 3GSR design facilitates energy recovery,radial brine transport,and directional salt crystallization,thereby resulting in an ultrahigh evaporation rate of 9.05 kg m^(-2) h^(-1)6 in 25 wt%brine under 1-sun illumina-tion for 48 h ***,the directional salt crystallization on its outer surface not only enlarges the evaporation area but also achieves an ultrahigh salt collection rate of 2.92 kg m^(-2) h^(-1),thus enabling ZLD ***,3GSR exhibits a record-high water production rate of 3.14 kg m^(-2) h^(-1) in an outdoor *** innovative solution offers a highly efficient and continuous solar desalination method for water production and ZLD brine treatment,which has great implications for addressing global water scarcity and environmental issues arising from brine disposal.

轮缘推进器(RDT)作为一款新式高性能推进器,其桨叶设计还没有统一的规范。文章基于计算流体力学(CFD)求解器STAR-CCM+比较了常规Ka4-70的反厚度桨型(AT-Ka4-70)和NACA66(mod)+a=0.8拱高的翼型的反厚度桨型(RIM4-70)的轮缘推进的水动力性能。通过对其压力分布、流场分布以及涡量分布的计算分析,以及盘面比0.7约束下,分析了不同桨叶数和螺距比参数对轮缘桨型的影响,得到其敞水性能K-J图。结果表明,RIM4-70的NACA66(mod)+a=0.8拱高翼型的压力在弦长上的分布,除了导边小部分有较大的突起,其他大部分分布较AT-Ka4-70桨缓和饱满。经过空化系数对压力系数的约束分析,得到RDT RIM4-70整体抗空化能力更强,能量耗散较少。同时,RIM4-70桨型的推进效率在低进速系数的情况下较AT-Ka4-70桨较高,特别是在进速系数为0.1时,两者效率相差11.1%。研究结果为轮缘推进器螺旋桨的翼型参数设计提供参考及应用价值。
