Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

The nitrogen(N) and phosphorus(P) budget and the ecological efficiency of a polyculture system of sea cucumber(Apostichopus japonicus), jellyfish(Rhopilema esculenta) and shrimp(Fenneropenaeus chinensis) were studied in a cofferdam, 120.2 ha in size. The nutrients were supplied by spring tide inflow. In total, 139600 kg N yr-1 and 9730 kg P yr-1 input to the system; while 118900 kg N yr-1 and 2840 kg P yr-1 outflowed from the system concurrently, thus the outflow was 85.7%(N) and 29.2%(P) of inflow. The production of N and P was 889.5 kg yr-1 and 49.28 kg yr-1(sea cucumber) and 204 kg yr-1 and 18.03 kg yr-1(jellyfish and shrimp), respectively. The utilization rate of N and P by polycultured animals was 7.8‰ and 6.9‰, respectively, 21.9% and 38% higher than that of monocultured sea cucumber. Our results indicated that the polyculture system was an efficient culture system of animals and a remediation system of coastal environment as well; it scavenged 14.3% and 70.8% of N and P, respectively. Such an ecological efficiency may be improved further by increasing either the stocking density or the size of sea cucumber or both.

新时代以来,东北文学呈现出繁荣发展的景象,综合考察其内涵与外延,是认识其价值较为客观的途径。如果将“铁西三剑客”等东北青年作家创作定义为狭义的“新东北文学”,那么本文讨论的则是新时代以来反映东北区域社会人生的广义的“新东北文学”。新东北文学作为新时代中国文学的一部分,具有其局部性和特殊性,将东北作为方法,可以使新东北文学获得超乎其本来存在范围的意义,承载思想交流的使命,从而理解新时代中国文学的发展脉络。通过对东北老工业基地的衰落与振兴,新世纪以来的城乡互动、地方与世界的关系等问题的分析,能够发现新东北文学超越区域限制的诸多想象,以及认识和解释世界的尝试。

In this paper,we obtain some asy mptotic behav ior results for solutions to the prescribed Gaussian curvature ***,we prove that under a con-formal metric in R^(2),if the total Gaussian curvature is 4π,the conformal area of R^(2)is finite and the Gaussian curvature is bounded,then R^(2)is a compact C^(l,α)surface after completion at∞,for anya∈(0,1).If the Gaussian curvature has a Holder decay at in-finity,then the completed surface is C^(2).For radial solutions,the same regularity holds if the Gaussian curvature has a limit at infinity.

为了提高木瓜的干燥均匀性与干燥速率,优化干燥工艺,对木瓜热泵干燥的干燥特性进行了研究。进行了单因素木瓜热泵烘干试验,并根据试验条件,抽象出数值模型进行仿真研究。通过调整模型中来流温度、湿度、速度和木瓜切片厚度等参数,得到了木瓜切片在不同参数下的干燥均匀性与温升曲线。对比试验与仿真结果得到了提高木瓜干燥工艺中均匀性与速率的优化方案。当来流温度55~70℃,湿度15%~30%,速度0.2~0.8 m/s时,提高风速可以有效提高木瓜切片烘干的均匀性和速率;试验中干燥不均匀性系数ε与模型预测值之间的最大误差为0.218,平均误差为0.064,极大值与仿真结果相比偏大36.75%;干燥前期拟合效果较好,试验中后期木瓜不均匀性系数对比模拟结果相对较高。
