0 INTRODUCTION To relieve the short supply of suitable land for residing,cultivating,and commerce,it is accepted to reclaim land from lakes,river estuaries,and coastal regions in many countries(Mancini et al.,2020).The large-scale reclamation activities have an irreversible effect on the mico-geomorphology and hydrodynamic system of seasonally flooded areas(Zhang et al.,2019;Yu et al.,2018).For example,coastal regions reclaimed extended the groundwater flow paths,as well as created groundwater level rise,resulting in water-logging in the reclaimed area(Hu et al.,2008).Similar changes in groundwater flow systems may alter groundwater-lake water interactions,and it can ultimately affect the water cycle in the lake ***,such detailed studies are presently *** addition,natural exchanges between the lake and groundwater systems can be strongly affected by physical hydrological processes(Javadzadeh et al.,2020),chemical properties(Kamtchueng et al.,2015),and bioto behavior(Hancock et al.,2005).

选取陈皮、柠檬和金桔这三种柑橘类植物为原料,利用超临界CO_(2)萃取法高效提取精油。采用GC-MS分析样品成分,进而探究三种精油对金黄色葡萄球菌和烟曲霉菌的抑菌活性。研究表明:柠檬精油中的醇类(3.41%)、醛类(2.55%)、酮类(2.03%)、酯类(7.17%)和除柠檬烯以外的萜烯类化合物(34.06%)含量较高,D-柠檬烯含量是这三种精油中最低的(46.52%);陈皮精油中的萜烯类(86.34%)、酚类化合物(1.82%)含量较高;金桔精油中的酸类化合物(12.71%)和D-柠檬烯(72.69%)含量较高。精油对金黄色葡萄球菌和烟曲霉菌的抑菌活性均为柠檬精油>陈皮精油>金桔精油。在这三种柑橘类精油中D-柠檬烯并非是唯一的抑菌成分,精油的抑菌活性也与除D-柠檬烯以外的抑菌成分密切相关。其中柠檬精油中含量丰富的γ-松油烯和β-蒎烯等其他抑菌成分可与D-柠檬烯协同起到有效提高精油抑菌活性的作用。该方法所提取的精油可为相关天然抑菌产品研发提供一定帮助。

A common view on meridional deflection of eddy propagation is poleward for cyclones and equatorward for anticyclones. This widely accepted polarity-sensitive pattern has been increasingly undermined given that it is systematically violated on both zonal and regional scales as recently reported. Here, we approach the problem by exploring these violations in terms of eddy effects of spatiotemporal geostrophy, thermal fading, and flow dragging, yielding the following main conclusions.(1) The polarity-dependent deflection discrepancy is a pseudo feature resulting from a biased fit to the normalized eddy tracks which are spatially asymmetric(though azimuthally symmetric) between the two signs;Instead, the primary pattern of eddy deflection appears to be geographically correlated and polarity independent.(2) Geostrophic adjustment plays a critical role in defining the meridional movement of an eddy. Specifically, a consistent poleward(equatorward) trajectory bending of spatially(temporally) ageostrophic eddies is observed irrespective of their polarity.(3) The mechanism of eddy deflection is also determined by its zonal propagation direction. Westward propagating eddies are substantially affected by thermal fading, while opposite ones by flow dragging. A realistic and comprehensive understanding of eddy deflection mechanisms serves as a significant contribution to the prediction of eddy trajectory, and the protection of ocean environment.

以菇娘为试验材料,采用4、8、12℃及室温(均温28℃)贮藏的方法,研究了不同温度对菇娘贮藏品质(维生素C、可滴定酸、可溶性固形物含量)及采后生理(相对电导率、丙二醛含量、超氧化物歧化酶(SOD)活性)的影响。结果表明:不同贮藏温度对菇娘果实品质和采后生理影响不同,在室温下品质和生理变化最快,其次是12℃,变化最小的是4℃。贮藏温度对菇娘维生素C和可滴定酸含量有显著影响,低温有利于减缓菇娘品质的下降速率;随着贮藏时间的延长,菇娘的相对电导率和丙二醛含量不断增加,SOD活性不断降低,低温贮藏有利于抑制电导率和丙二醛含量的增加,同时保持较高的SOD活性。4℃和8℃贮藏均能提高菇娘的贮藏品质和生理活性,以4℃表现最佳。
