A new zinc polymer, {Zn（O2CC12H8CO2）（H2O）}, or {Zn（DPHA）（H2O）}n （O2CC12H8CO2, DPHA = 1,1′ -biphenyl-2,2′-dicarboxylate dianion） has been synthesized under hydrothermal conditions. The crystal is of monoclinic, space group P21/c with a = 12.8418（5）, b = 5.9505（2）, c = 17.2989（5） A, β = 104.020（2）°, V = 1282.52（8） A^3, C14H10O5Zn, Mr= 323.61, Z = 4, Dc = 1.676 g/cm^3,μ = 1.930 mm^-1, F（000） = 656, R = 0.0766 and wR = 0.1871 for 1775 observed reflections （I 〉 2σ（I））. It consists of Zn2（DPHA）2（H2O）2 units, which are further extended into a one-dimensional double helical-chain polymer via Zn-O bonding. The hydrogen bonding interactions extend the helical chains into a two-dimensional layer structure.

The title compound, [Co（C7N2H7O2）2]n·nH2O 1, was synthesized via the hydrothermal reaction of Co（OAc）2 with 3,5-diaminobenzoic acid and characterized by elemental analysis and infrared spectra. The crystal crystallizes in the monoclinic system, space group P21/c with a = 7.456（3）, b = 9.972（3）, c = 10.391（3）A, β= 106.435（2）°, V = 741.0（4） A^3, Z = 2, C14H16CoN4O5, Mr = 379.24, Dc = 1.700 g/cm^3, F（000） = 390 and μ（MoKa） = 1.194 mm^-l. The final R = 0.0324 and wR = 0.0886 for 1516 observed reflections with I 〉 2σ（I） and R = 0.0337 and wR = 0.0899 for all data. X-ray diffraction studies reveal that the title compound has an interesting 3D microporous architecture with guest water molecules inside the channel. Each Co atom, adopting a distorted octahedral geometry, is coordinated by two O atoms from two 3,5-diaminobenzoate ligands and four N atoms from four symmetry-related 3,5-diaminobenzoate ligands.

为考虑孔隙介质对波浪传播变形带来的衰减效应,在渗透介质流体的控制方程中引入线性阻力、非线性阻力和惯性力。自由表面采用精确的运动学和动力学边界条件,水底边界条件采用精确的动力学边界条件,自由水体和渗透介质水体之间满足垂向速度连续、水平速度满足动量相等条件。首先推导最高空间导数为3的以两组计算速度表达的适合单层渗透海床波浪运动的三维Boussinesq型水波方程。其次,对新给出的方程进行傅里叶分析,并将方程的相速度及衰减率与Stokes线性波的解析解进行比较。在1%误差下,相对水深h_(2)/h_(1)=0.1~10,方程的解析解在无因次水深h_(1)/L<1.0(深水波长L=gT^(2)(/2π))范围内与Stokes线性波的解析解都有较好的吻合,这超过了历史文献中任一个Boussinesq型水波方程的适用范围。进而建立立面二维水槽数值模型,并利用预报-校正-迭代的有限差分方法对数值模型进行求解,在变量对时间的导数求解中选择混合四阶AdamsBashforth-Moulton格式。最后,利用数值模拟再现波浪在渗透地形上的传播变形,并与相关试验结果进行比较,二者吻合程度较高。

对于光伏发电系统的保护,低压直流断路器具有举足轻重的地位。文章对光伏低压直流断路器电磁脱扣器的静态特性进行了分析,在有限元分析软件ANSYS中建立了电磁脱扣器的三维模型,并进行加载、求解,从而得到了不同电流、不同气隙下动铁心所受电磁吸力大小的二维静态特性曲线图。之后对有限元分析软件ANSYS进行了二次开发,得到了动铁心所受电磁吸力在不同结构参数下的变化曲线并给出了相应的解释,同时根据结构参数变化对初始位置电磁吸力的影响为各参数提出了相应的公差建议。
