The complex [Cu2L2(Py)2] (H2L=2-aminobenzoic alcohol condensation salicylaldehyde) was obtained. A single-crystal X-ray study shows that the complex is a binuclear compound (Cu2C38H32N4O4). The coordination geometry about each copper atom is best described as a distorted square pyramid. The compound [Cu2L2(Py)2] belongs to monoclinic system with space group P21, lattice constants: a = 10.3881(1), b = 17.9724(1), c = 17.5800(2) ? b =90.4880(1), V= 3282.05(5) 3, Z= 4, Mr =735.75, Dc=1.489 g/cm3, m= 1.344mm-1, F(000) = 1512, R=0.0519, wR=0.1092 for 6725 reflections with I >2s(I). The distances between Cu(II) and O atoms are range from 1.898(6) to1.976(5)? between Cu(II) and N atoms are range from 1.990(6) to 2.369(7)? The Cu(1)Cu(2) bond length is 3.024(4) ?

传统的肺功能检测仪是基于测量呼气和吸气期间的气流和压力变化来评估受测者的呼吸功能.这些技术主要基于机械式压差传感器或涡轮传感器,通过测量受测者口腔吹气和吸气的能力来评估其肺功能.其所测得的肺功能参数包括峰值呼气流量(peak expiratory flow,PEF)和用力肺活量(forced vital capacity,FVC)等.本文报道了基于动态湿度传感技术发展而来的穿戴式呼吸功能检测系统(穿戴式呼吸波谱仪).基于湿度传感器的特点,对呼吸检测原理与设备的定量设计与模拟潮气实验进行了全面的探索.根据达西定律,通过穿戴式呼吸波谱仪的气体流量与其内外压差成正比关系,该系统符合压差式传感原理.以此为基础,根据其结构特点,建立PEF和FVC与传感器电信号变化的定量关系.实验结果验证了波谱仪内相对湿度的最大变化率与PEF呈线性正相关的关系.波谱仪的模拟潮气实验结果表明,测试范围为180—840 L/min条件下,PEF的示值误差小于10%,相邻测试误差小于5%,频率响应测试误差小于12%,符合呼气峰值流量计行业标准的要求.此外,将传统便携式肺功能检测仪作为对照,进行不同PEF(300—720 L/min)和FVC(3—6 L)条件下的模拟潮气实验.结果表明,波谱仪所测PEF和FVC的平均示值误差分别约为0.35%和0.23%,均远远小于便携式肺功能检测仪,充分验证了该系统对肺功能实时评估的准确性和可靠性.更重要的是,在模拟自由呼吸条件(PEF为12—24 L/min,FVC为0.5—0.7 L)下,波谱仪的电信号变化与自由呼吸体积仍呈线性关系.因此,穿戴式呼吸波谱仪可对人体自然、微弱的鼻呼吸,进行自由、动态、定量的长期监测.所测量人们的自由呼吸波谱在人体肺功能实时监测以及呼吸系统疾病远程监测方面,具有巨大的应用潜力.

Soil erosion gradation is a robust and objective quantitative indicator of soil erosion intensity. Recent applications of soil erosion gradation have focused on monitoring soil erosion with models or simulation of soil erosion through gradation trends. However, soil erosion simulation accuracy is generally being reduced due to the rare consideration of the relationship between soil erosion gradation and erosion evolution. In this study, we investigated different soil erosion intensity grades to demonstrate their sensitivity to types and rates of erosion. Specifically, the objective was to define the relationship between soil erosion gradation and soil erosion evolution in Changting, an undeveloped area in Fujian Province, China, for four time intervals (1975, 1990, 1999, and 2006). The time series of erosion gradation were developed by modeling analysis with integration of several erosion indicators, and the relationships between the erosion grades and evolution types and rates were quantified. Comparison of the collapsing forces with natural and restoring forces based on human activity demonstrated that there existed an obvious spatial uncertainty in the erosion evolution types, both positive and negative succession coexisted, and the evolution rates were mostly influenced by the force of policy orientation. The impacts of these driving forces were eventually reflected in the erosion intensity gradation and erosion evolution. The correlation between the negative succession rate and erosion intensity gradation was weak and showed a poor contribution to the average succession rate, while the negative correlation between the positive succession rate and erosion intensity gradation would be increasingly clear as time passed.

在系统化全域推进海绵城市建设的背景下,低影响开发设施布设对城市雨洪过程具有重要影响。以江苏省宜兴市区为研究对象基于暴雨洪水管理模型SWMM建立研究区雨洪模型,考虑以径流总量削减率、悬浮物负荷削减率、生命周期成本、低影响开发设施占地面积建立综合目标函数,通过权重调整目标参数的优先级,运用遗传算法求解得到不同情景下低影响开发设施的最佳布设方案。结果表明:①在同等权重条件下,生命周期成本对优化计算的影响远大于面积,径流总量削减率与悬浮物负荷削减率影响较小;②位于管道上游的小面积汇水区内低影响开发设施的优化布设易受降雨重现期影响。研究成果可为海绵城市建设中低影响开发设施的优化布设及城市内涝防治研究提供参考。
