We investigated the properties of strange quark matter in an external strong magnetic field with both confinement and leading-order perturbative interactions considered. It was found that the leading-order perturbative interaction can stiffen the equation of state of magnetized quark matter, while the magnetic field lowers the minimum energy per baryon. By solving the Tolman–Oppenheimer–Volkoff equations, we obtain the internal structure of strange stars. The maximum mass of strange stars can be as large as 2 times the solar mass.

The water requirement pattern for tobacco（Yun 85） was identified based on analysis of data obtained from pot experiments in a canopy at the Xiuwen Irrigation Test Central Station in Guizhou Province, China. The results showed that the tobacco water requirement and the tobacco water requirement intensity throughout the growth period in pot experiments were significantly lower than those in field production. In pot experiments, the tobacco water requirement throughout the growth period ranged from 159.00 to 278.90 mm, with a reduction in the range of241e441 mm, as compared with that in field production. Also, the average water requirement intensity at the vigorous growing stage was1.97 mm/d, and the water requirement and water requirement module were 33.80e72.60 mm and 16.39%e33.09%, respectively, at the group stage, almost equal to their values at the vigorous growing stage. The patterns of the tobacco water requirement and water requirement module in pot experiments were different from those in field production. In pot experiments, the tobacco water requirement and water requirement module ranked the highest at the mature stage, followed by those at the group/vigorous growing and rejuvenation stages, while the water requirement intensity ranked the highest at the vigorous growing stage, followed by those at the mature, group, and rejuvenation stages. The pattern of the water requirement intensity in pot experiments was consistent with that in field production. In addition, the response of the tobacco water requirement to water deficit was also analyzed. Serious water deficit at the vigorous growing stage and continuous water stress at the group,vigorous growing, and mature stages can greatly influence the tobacco water requirement. Water deficit led to reductions in the water requirement and water requirement intensity at each growth stage. The vigorous growing stage exhibited the highest sensitivity to water *** lower limit of moderate soil water stress at

2,2＇-Bisbenzimidazole derivative （L） was designed as a fluorescent chemosensor for Fe3＋. This structurally simple chemosensor displays significant fluorescence quenching with increasing concentrations of Fe3＋. L exhib- ited high selectivity and antidisturbance for Fe3＋ among environmentally relevant metal ions in aqueous media. The method of Job＇s plot indicated the formation of 1 ; 2 complex between L and Fe3＋, and the possible binding mode of the system was also proposed. In addition, further study demonstrates the detection limit on fluorescence response of the sensor to Fe3＋ is down to 10-7 mol·L-1 range. The binding mode was investigated by fluorescence spectra, ESI-MS, IR data, ^1H NMR, ^13C NMR and crystal data.

采用静态箱-气象色谱法对控制灌溉稻田CH4和N2O排放进行了观测,研究控制灌溉模式对稻田CH4和N2O排放的影响,并对其温室效应进行了评估。结果表明,控制灌溉稻田CH4排放通量明显低于淹水灌溉稻田,且主要集中在分蘖前期和中期,全生育期CH4排放量比淹水灌溉稻田减少73.2%～85.0%。控制灌溉稻田N2O排放通量在水稻全生育期大部分时间都要大于淹水灌溉稻田,稻季N2O排放量分别为106.65 mg/m2和96.40 mg/m2,控灌稻田较淹灌稻田增加了10.6%。控制灌溉稻田稻季排放CH4和N2O的全球增温潜势(GWPs)为726 kg/hm2,较淹水灌溉稻田减少了59.1%。控制灌溉模式能显著降低CH4和N2O综合排放的全球增温潜势。

沟塘系统是控制农田面源污染的有效措施,本文通过修整灌区内承泄沟塘、重建其水生植物系统,研究了沟塘湿地对稻田排水的原位削减能力及机理。试验结果表明,通过沟塘底泥、水生植物等的综合净化作用,沟塘出流水中总氮TN和总磷TP平均质量浓度分别较入口减小22.01%和9.59%,实现了对稻田排水中氮磷的原位削减,其中氮磷单峰浓度消减均近似服从指数规律。较小的沟塘入流浓度和较长的沟塘净化时间利于获得更大的消减率,因此,建议利用排水沟系对稻田排水进行先期调蓄,初步净化后再排入沟塘,以提高沟塘净化效果。沟塘拦水坝的修建使得底泥吸附在水体净化过程中作用更加明显,0～40cm深底泥在稻麦轮作年TN截留量达1.559kg·m-2、TP累积量达0.394kg·m-2,吸附量可观;水生植物氮磷吸收是沟塘水质净化的重要途径,收割是实现其净化有效性的关键环节,仅移除芦苇和茭草茎叶,可除去氮193.69kg·hm-2和磷33.49kg·hm-2。芦苇和茭草综合对比表明,茭草更适于当地排水沟塘选用。
