Novel stable high spin molecules possessing three different arranged fashions are designed with - · N-N< as a spin-containing(SC) fragment, phenylene as an end group and various aromatic molecules, such as benzene(1)... 详细信息

Novel stable high spin molecules possessing three different arranged fashions are designed with - · N-Nling(FC) unit. The effects of the different coupling units on the spin multiplicities of the ground states and their stabilities were investigated by means of AM1-CI approach. It has been found that the spin densities on the two atoms of the SC fragment are different from delocalization results in the specific stability of - · N-Nlities of the triplet states decrease when the distance between the atoms of central SC(-N-) increases. It is shown that the heterocycles as the coupling units have influence on the stabilities of the high-spin ground states. That the heteroatom lying in m -phenyl can improve ferromagnetic coupling, while the heteroatom lying in o -phenyl or p -phenyl is not in favor of the ferromagnetic coupling.

在水声通信中,传统的正交频分复用(Orthogonal Frequency Division Multiplexing, OFDM)系统需要大量导频数量和循环前缀以维持系统性能,严重浪费有限的频域资源。因此,利用深度学习辅助OFDM恢复失真的传输数据。具体地讲,利用改进的残差块提取和双向记忆接收信号。将自归一化网络(Self-Normalizing Network, SNN)与注意力机制结合,有效分配信道权重,以便系统更有效地利用信道资源,最小化信号失真。使用深度神经网络(Deep Neural Network, DNN)实现接收信号的分类,以准确地恢复接收信号。提出的ICANet(Improved Residual Network, Convolutional Neural Network and Attention Mechanism Self-Normalizing Network)模型可应用于由Bellhop软件生成的水声环境。仿真结果证明,与传统技术中的最小二乘法(Least Square, LS)以及现有的深度学习模型相比,所提出的模型在循环前缀受限的情况下可达到更低的误码率。

Chinese Journal of Polymer Science 2014年第2期32卷 163-168页

作者：何德良 Fei li San-bao Xia Fu-rong liu Ying Xiong 张泉 College of Chemistry and Chemical Engineering Hunan University College of Civil Engineering Hunan University

A new type of polymerizable ionic liquid （IL） 1-（3-aminobenzyl）-3-methylimidazolium chloride （AMIC） was synthesized to obtain a novel polymer salt poly（1-（3-aminobenzyl）-3-methylimidazolium chloride）（PAMIC）. The AMIC was structurally characterized by mass spectrometry and Fourier transform infrared spectrometry （FTIR）. The structure, morphology and properties of PAMIC were investigated by FTIR, ultraviolet visible absorption spectra （UV-Vis）, scanning electron microscopy （SEM）, energy dispersive X-ray spectroscopy （EDX）, conductivity measurement and thermo- gravimetric analysis （TGA）. The PAMIC was spherulitic with an average diameter of about 50 nm and showed high conductivity and excellent thermal stability.
