The present work was carried out to evaluate the safety of shrimp(Solenocera crassicornis)treated with different concentrations of sodium metabisulfite(SMB)by soaking or spraying during frozen *** soaked in higher concentrations of SMB showed higher sensory scores,lower total color differences,and better anti-melanosis effects than shrimps in the control and other treatment groups throughout frozen storage(−18℃).Lower total volatile basic nitrogen and thiobarbituric acid reactive substances and higher salt soluble protein contents were detected in shrimp soaked with high doses of SMB compared with other *** addition,lower counts of total aerobic plates and psychrotrophic bacteria were observed in shrimp treated by soaking with higher doses of SMB than those in control shrimp and shrimp treated with other methods during frozen storage(−18℃).However,the SO2 content of 5%SMB-soaked samples exceeded the maximum allowable limit of 100mgkg−***,the use of 1.5%SMB soaking to treat shrimp results in good antioxidant and antimicrobial effects and,thus,may be suggested to preserve *** under frozen *** results of this study present important guidance on the use of SMB to maintain the quality of marine-trawling shrimp from manufacturing to consumption.

根据光波导短程透镜母线曲率半径与光传输损耗的关系,利用数值计算的方法,通过计算不同母线参数条件下,四种解析解设计的短程透镜母线曲率半径,研究比较了短程透镜卷边对其损耗的影响,得出了短程透镜损耗与其有效区半径关系的曲线图,发现透镜凹面半径一定时,有效区半径越小,即卷边越大时,光传输损耗越小;短程透镜的解析改进解和最优解设计的透镜卷边存在曲率奇点。并由此得出了四种解析解设计的短程透镜有效区半径选取原则及其满足低损耗条件的取值范围。

Optical skyrmions formed by photonic spin–orbit(SO)coupling are of significant interest in high-dimensional optical information *** report the formation mechanism and non-Hermitian properties of skyrmionlike states in a circular confinement potential with photonic SO coupling,which is preferably realized in a concave-planar microcavity *** show that the effective photonic gauge field leads to two split manifolds of degenerate skyrmions whose spin textures can be controlled via the non-Hermitian properties by introducing circularly polarized gain and loss,exhibiting dramatically discrepant evolutions at the two sides of the exceptional point(EP).Furthermore,the lifetime degeneracy can be lifted by spatially inhomogeneous pumping according to the non-Hermitian mechanism,enabling the possibility for the skyrmion *** introducing shape asymmetry of the confinement potential,a double EP evolution can be achieved,which allows non-Hermitian control of the SO coupled states with higher degrees of *** results open the way for the non-Hermitian control of photonic spin in confined systems,which would be of great significance for the fundamentals of advanced optical information processing.

采用SBR(序批式活性污泥法)以及在SBR反应器中投加天然沸石的方式对Fenton法预处理后的7-氨基头孢烯酸(7-ACA)废水进行处理,考察了驯化污泥、未驯化污泥及投加天然沸石后驯化污泥对废水中CODCr值降低和NH3-N的去除效果。结果表明,采用逐渐增加进水中7-ACA原水在混合废水中的比例可实现对污泥的驯化,经39d驯化后SBR对CODCr值降低率保持在71.8%-76.5%;驯化污泥对Fenton法预处理废水中CODCr值平均降低率为79.9%,NH3-N平均去除率为74.9%,明显好于未驯化污泥;SBR反应器中投加天然沸石后,其对废水中NH3-N的平均去除率为81.9%,可有效提升驯化污泥对废水中NH3-N的去除效果。
