We investigate the influence of the initial mixture of qubits and the dissipation on the entanglement transferfrom three-qubit Greenberger-Horne-Zeilinger (GHZ) and W state fields to three matter qubits,which are trapped inthree spatially separated *** find that at gt≈11.07,the entanglement transfer can be almost complete nomatter what state the qubits are initially prepared *** the dissipation is taken into account,we tind that thespontaneous emission plays the similar role to the cavity damping in the entanglement transfer,and the decay rate ofthe GHZ state is larger than that of the W state.

本研究搭建以黄铁矿-生物炭为基质的人工湿地,分析了溶氧浓度对海水养殖尾水处理效果的影响。当进水溶氧浓度为3~5 mg/L和6~8 mg/L时,人工湿地对TN的去除率为20%~30%;当进水溶氧浓度为0~2 mg/L时,TN去除率在40%以上,但生成的NO_(2)-N浓度达到5.07 mg/L,危害生物健康。高溶氧浓度更有利于磷酸盐的去除(PO_(4)-P),当进水PO_(4)-P浓度为33.10 mg/L时,进水溶氧为6~8 mg/L的人工湿地对PO_(4)-P的去除率在37%以上。SEM-EDS扫描显示,处理过养殖尾水的黄铁矿表面存在铁磷配合物,这进一步证明了该系统对尾水中的磷有一定去除能力。微生物群落组成分析表明,适当提高进水溶氧浓度有利于黄铁矿-生物炭基人工湿地微生物富集。结果表明,本研究所构建的人工湿地系统对高溶氧养殖尾水有较好的处理能力,为海水养殖尾水的处理提供了理论依据。

利用水化学分析和多同位素联合技术(δ^(18)O-H_(2)O、δ^(15)N-NO_(3)^(-)和δ^(18)O-NO_(3)^(-)),研究大同盆地地下水硝酸盐来源及转化过程,借助MixSIAR模型定量解析各污染源的贡献率.结果表明,地下水中NO_(3)^(-)-N、NO_(2)^(-)-N和NH_(4)^(+)-N平均浓度分别为32.07,0.96,0.61mg/L,以NO_(3)^(-)-N为主,最高浓度达538.61mg/L,超过地下水质量(GB/T 14848-2017)Ⅲ类标准(20mg/L)27倍,超标率达39.13%;垂向上,地下水NO_(3)^(-)-N浓度随井深增加而降低,即浅层地下水(均值34.26mg/L)>中层地下水(22.05mg/L)>深层地下水(13.07mg/L).硝化作用是地下水氮转化的主要机制,反硝化作用不明显.污水粪肥、土壤氮和化学肥料是造成地下水硝酸盐污染的主要原因,其平均贡献率分别为浅层地下水:污水粪肥(33.6%)>土壤氮(33.5%)>化学肥料(21.5%),中层地下水:污水粪肥(43.3%)>土壤氮(34.4%)>化学肥料(18.1%),深层地下水:土壤氮(54.4%)>化学肥料(25.1%)>污水粪肥(18.5%),不确定性分析表明化学肥料和土壤氮的不确定性指数UI90值较高,对硝酸盐污染的贡献率表现出较大的不确定性.研究成果为地下水氮转化和污染来源解析提供参考依据.

Permanganate was used as an oxidant to control estrone in the present study. Kinetics was determined at pH 2.5-9.4 and temperature 15–40°C for the reaction of estrone with potassium permanganate. It was found that the reaction is second-order overall and first-order with respect to both estrone and permanganate. The second-order rate constant for the reaction at pH 5.8 and 25°C is 44.45 L mol-1 s-1. The reaction rate first decreased with the increase of pH in the range of 2.5-6.6 and then increased greatly with the increase of pH in the range of 6.6-9.4. In addition, the rate constant exponentially increased with the increase of reaction temperature. Removal of estrogenicity was also investigated during the degradation of estrone using yeast estrogen screen (YES). Results show that the estrogenicity increased in the initial 15 min of reaction and then decreased fast, with a removal rate of 73.8% within the 30 min of reaction. Results also demonstrate that the reaction rate between estrone and permanganate is faster in natural water background than in the ultra-pure water system. Permanganate oxidation is therefore a feasible option for removal of estrone in drinking water treatment processes. However, the contact time must be enough in order to remove estrone without causing the increase of estrogenicity.

The thermal lensing effect generated in an end-pumped lightly doped Nd:GdVO4 crystal was found to be considerably weaker than that in Nd:YVO4 having the same Nd3+ concentration. Consequently, the laser performance of Nd:GdVO4 at high pump powers over 20 W was found to be superior to that of Nd:YVO4. TEM00 mode cw radiation of 14.3 W at 1.06μm was achieved with an optical conversion efficiency of 55%, and average slope efficiency of 62%.

A novel micromechanical bridge-shaped voltage-controlled oscillator with high Q value was fabricated. The core of this kind of oscillators is an electrothermally excited and piezoresistively detected micromechanical bridge resonator. Its resonance frequency can be adjusted by changing the DC voltage applied to the Wheatstone bridge. Theoretical analysis and experimental data show that its resonance frequency is linear with the square of the DC voltage. The linearity is better than 0.16% and the adjustable frequency range excels 17.15%.
