Nickel (hydr)oxide (NiOH) is known to be good co-catalyst for the photoelectrochemical oxidation of water,and for the photocatalytic oxidation of organics on different semiconductors.Herein we report a greatly improved activity of Bi_(2)MoO_(6)(BMO) by nickel hexammine perchlorate (NiNH).Under visible light,phenol oxidation on BMO was slow.After NiNH,NiOH,and Ni^(2+)loading,a maximum rate of phenol oxidation increased by factors of approximately 16,8.8,and 4.7,respectively.With a BMO electrode,all catalysts inhibited O_(2)reduction,enhanced water (photo-)oxidation,and facilitated the charge transfer at solidliquid interface,respectively,the degree of which was always NiNH>NiOH>Ni^(2+).Solid emission spectra indicated that all catalysts improved the charge separation of BMO,the degree of which also varied as NiNH>NiOH>Ni^(2+).Furthermore,after a phenol-free aqueous suspension of NiNH/BMO was irradiated,there was a considerable Ni(Ⅲ) species,but a negligible NH_(2)radical.Accordingly,a plausible mechanism is proposed,involving the hole oxidation of Ni(Ⅱ) into Ni(Ⅳ),which is reactive to phenol oxidation,and hence promotes O_(2)reduction.Because NH_(3)is a stronger ligand than H_(2)O,the Ni(Ⅱ) oxidation is easier for Ni(NH_(3))6+than for Ni(H_(2)O)6+.This work shows a simple route how to improve BMO photocatalysis through a co-catalyst.

核数据的不确定度已成为反应堆物理计算结果不确定度的主要来源,而不确定度计算需要的核截面协方差数据处理软件强烈依赖于国外相关计算软件,目前国内对核数据协方差信息处理软件鲜有报道,且对其处理方法和理论研究不多,为此,本文深入研究多群协方差信息处理理论,在自主开发的先进核截面处理程序AXSP中开发了多群协方差处理模块CovarXS,基于ENDF/B-Ⅶ.1评价核数据库制作了33群协方差数据库,通过与NJOY2016中的ERRORR模块计算结果对比,产生的相对协方差数据的相对误差小于1.0%,验证了CovarXS模块开发的正确性。在此基础上,利用制作的33群协方差矩阵对MOX燃料钠冷快堆BN-600基准题进行了分析,对影响系统keff的不确定性最大的核素及其截面进行了分析。基于CovarXS模块和ERRORR计算得到的不同核素对keff的不确定度贡献的相对误差小于0.893%,由此说明CovarXS模块处理得到的多群协方差数据库精度与ERRORR模块生成的多群协方差数据库的精度相当。

兼具热和光稳定性的稀土稳定剂,对降低聚氯乙烯(PVC)加工成本,提高PVC的生产效率和打开稀土稳定剂的应用领域具有重要的意义,因此,通过人工加速紫外老化实验和户外自然光老化实验,研究了2,4-二羟基二苯甲酮镧(LBP)、2-苯甲酰苯甲酸镧(LBA)及三元复合稳定剂对PVC光稳定性能的影响。结果表明:添加含LBP和含LBA的两种三元复合稳定剂(LBP∶ZnSt_(2)∶PE=2∶1∶2,LBA∶ZnSt_(2)∶PE=1∶1∶3)的PVC片材,人工紫外老化10 d后,失重率分别为2.7%和6.2%,自然光老化35 d后,拉伸强度保留率分别为87.6%和81.8%,复合稳定剂提高PVC的光稳定性能最佳。稀土稳定剂可以吸收PVC降解产生的氯化氢,降低氯化氢的浓度,从而减弱氯化氢对PVC降解的催化作用,抑制PVC脱去HCl形成双键,防止双键在氧作用下,形成过氧化物生成羰基化合物。

用水热法制备了钙镧类水滑石(Ca-La-LDHs),研究了阳离子配比、水热时间和水热温度对Ca-La-LDHs的结构及PVC热稳定性能的影响,得到最佳的合成条件为:n(Ca^(2+)):n(La^(3+))=3:1,水热温度170℃,水热时间8h,并对最佳条件产物进行了XRD及红外光谱、热分析、SEM表征。通过刚果红实验、高温老化实验、转矩流变实验、拉伸实验和电导率实验,研究了Ca-La-LDHs对PVC的热稳定性能、塑化性能及力学性能的影响,结果表明,钙镧类水滑石能显著提升PVC的热稳定性能,其静态热稳定时间为87min。Ca-La-LDHs样品降低了平衡转矩,提升了动态热稳定时间,显著延缓了PVC释放HCl的速率,从而提升了动态热稳定性。Ca-La-LDHs提升了PVC板材的抗拉强度和断裂伸长率。Ca-La-LDHs热稳定剂阻碍了PVC中的C-Cl和C-H键的断裂,抑制HCl和C=C键的生成,减少了HCl对PVC降解的进一步催化。

The Jurassic oceanic crust is the oldest existing oceanic crust on earth,and although distributed sparsely,carries essential information about the earth's evolution.The area around the Pigafetta Basin in the west Pacific Ocean(also known as the Jurassic Quiet Zone,JQZ)is one of a few areas where the Jurassic oceanic crust is present.This study takes full advantage of high-resolution multichannel seismic reflection profiles in combination with bathymetry,magnetic,and gravity data from the JQZ to examine the structure,deformation,and morphology of the Jurassic oceanic crust.Our results show the following insights:1)The Moho lies at 2–3 s in two-way travel time beneath the seafloor with the segmented feature.The gaps between the Moho segments well correspond to the seamounts on the seafloor,suggesting the upward migration of magma from the mantle has interrupted the pre-existing Moho.2)The oceanic crust is predominantly deformed by crustal-scale thrust faults,normal faults cutting through the top of basement,and vertical seismic disturbance zones in association with migration of thermal fluids.The thrust faults are locally found and interpreted as the results of tectonic inversion.3)Seafloor morphology in the JQZ is characterized by fault scarps,fold scarps,seamounts,and small hills,indicating the occurrence of active faults.4)The oceanic crust in the JQZ and East Pacific Rise has many structural and geometrical variations,such as the thickness of sediments,seafloor topography,basement morphology,fault size and type.

OBJECTIVES:To analyze the distribution characteristics of Traditional Chinese Medicine(TCM)syndromes in patients with oxaliplatin-induced peripheral neuropathy(OIPN)and observe the clinical efficacy of Bushen Yiqi formula(补肾益气方,BSYQF)in treating patients with OIPN.METHODS:A total of 89 patients with OIPN were enrolled in this study.The TCM syndrome characteristics were investigated by frequency analysis methodology after collecting and analyzing the TCM syndrome elements of the patients with the OIPN TCM syndrome element scale.Further,62 cases of cold-dampness obstruction syndrome and kidney-Qi deficiency and cold syndrome were selected and randomly divided into the control group(n=31)and the treatment group(n=31).The patients in the treatment group were treated with modified BSYQF,while those in the control group were treated with mecobalamin tablets for 3 weeks.The Levi sensory neurotoxicity score and the neuro-electrophysiological changes were observed before and after the treatment in both groups.RESULTS:The distribution of TCM syndrome types in 89 patients with OIPN were in order of kidney-Qi deficiency and cold syndrome(44 cases),cold-dampness obstruction syndrome(18 cases),Yin deficiency of liver and kidney syndrome(11 cases),blood stasis obstruction syndrome(7 cases),and dampness-heat obstruction syndrome(5 cases).Improvement in Levi sensory neurotoxicity score:After 3-week treatment,the total effective rate in the treatment group was higher than that in the control group(P<0.05).The subgroup analysis showed that the total effective rate in the treatment group of patients with kidney-Qi deficiency and cold syndrome was higher than that in the control group before and after treatment(P<0.05).Improvement in nerve conduction velocity:The sensory nerve conduction velocity of bilateral ulnar nerves improved in the control group after treatment compared with that before treatment(P<0.05).The sensory and motor nerve conduction velocities of the bilateral ulnar and bilateral peroneal nerves improved in the treatm

To explore the clinicopathological features of abound mitosis of the hepatocytes in intrahepatic cholelithiasis.The clinicopathological data of one case diagnosed as intrahepatic cholelithiasis was collected from Yantai Yuhuangding Hospital and the clinicopathological characters were discussed.A 68-year-old man suffered from the pain in the right upper quadrant and radiology showed multiple stones in the gallbladder and left liver.The images suggested intrahepatic cholelithiasis.The patient received gallbladder and partial hepatectomy.A large number of mitosis was observed and twelve nuclear fissions were found under high magnification,even in some area pathological nuclear fission could be observed in morphology.On the basis of detection in laboratory,the diagnosis of intrahepatic cholelithiasis was made.The patient did not receive any therapy after surgery.The patient was in a good condition after 18 months follow-up.Increased number of hepatic mitosis might be due to the stimulation from stones,hepatic biliary or secondary inflammatory.High index of proliferation should be prevented from the potential misdiagnosis of hepatic tumor.

针对低压配电网拓扑结构人工校验成本高、效率低等问题,提出了一种基于GIS和电压波形相关性分析的低压配电网拓扑识别方法。首先根据GIS平台里台区配变和用户的地理信息,结合户变关系空间约束,筛选出重叠区域和非重叠区域,初步确定非重叠区域的户变关系。其次分析重叠区域用户和相邻台区配变的电压序列相关性,分别采用欧氏距离、DDTW、皮尔逊相关系数3种指标进行评估,以确定重叠区域的户变关系。最后持续动态监控重叠区域的电压相关性趋势,当用户和台区配变的电压相关性发生剧烈变化时,重新计算用户和相邻台区配变的电压相关性,判断用户所属台区,向运维人员推送告警信息以待人工校核确认。算例验证了本文方法的有效性和可行性。
