Sichuan has completed the industrialization for a series of high - performance new materials and modified materials such as pps , high - end rare earth permanent magnet , lanthanum glass , high purity tellurium , fluoro rubber , organic silicon , high performance processing for general - purpose plastic , nano materials and wisker materials 已完成聚苯硫醚、高档稀土永磁材料、稀土镧系玻璃、高纯碲、氟橡胶、有机硅、通用型塑料高性能化、纳米材料、晶须材料等一批高性能新材料和改性材料的产业化。
Using the methods of fluoro - gold ( fg ) retrograde tracing combined with immuno - fluorescence histochemistry , cb - immunoreactive neurons expressed immunoreactivity for fos protein in nts which send their axons to bst were investigated . after injecting fg into bst mainly in lateral part , the fg retrogradely labeled neurons were found in the mid - caudal part of nts bilaterally with ipsilateral side predominance . cb - and fos - immunoreactive neurons were distributed equally in both sides of nts 结果显示：将荧光金（ fg ）注入一侧终纹床核外侧部（ bstl ）后，中尾段nts内双侧出现fg逆行标记神经元，注射区同侧占优势； nts的相同平面可观察到双侧等量分布的兔疫反应阳性的cb和fos神经元：三种神经元的分布有明显的重叠现象。
New trends in main high - tech fibers both in abroad and home are illustrated through a lot of facts recently , the development of high strength high modulus fibers and functional fibers are the fastest among the high - tech fibers , heat - resistant fibers and flame - resistant fibers are the second two , and the fluoro - containing fibers are relative low , the main reasons are also analyzed briefly 摘要通过大量事例论述了近期国内外主要高科技纤维的新发展动向，指出高强高模纤维和功能纤维是当前和未来发展最快的品种，耐高温纤维和抗燃纤维次之，含氟类纤维相对发展较慢，简要地分析其原因。
In the case of the unsaturated alcohols , such as hydroxyethyl acrylate ( hea ) , the paes showed the photo - alignment property to the nematic liquid crystals with the pretilt angle of 0 . 60 ? secondly , three kinds of fluoro - containing diamine monomers were prepared via the reduction reactions of the corresponding dinitro compounds , which were synthesized via the nitro nucleophilic displacement reactions of 3 , 5 - dinitro - 5 - trifluoromethyl benzene with diphenol compounds 此外，本论文还设计并通过3 ， 5 -二硝基三氟甲苯与二酚化合物的硝基亲核取代反应制备了二硝基化合物，将其还原最终合成了三种间位取代的含氟二胺单体tfpda 、 tfbpda与tfmda ，并对其聚合行为进行了研究。
In the thesis , we proposed a random lattice model of mea the lattice model randomly occupied by three kinds of particles , pt / c , nafion and ptfe ( poly - tetra - fluoro - ethylene ) , was generated on a computer by the means of monte carlo method . it was supposed that current was only produced on those catalysts which have not only channels of electrons via carbon but also have channels of proton via nafion . the purpose of the work , in a word , is to find how many catalysts , pt / c , with such a two - types channels 本文首先建立了质子交换膜燃料电池的膜电极的随机方格子模型，在电极模型各格点位置用montecarlo方法生成随机分布的电极粒子、 nafion粒子和聚四氟乙烯团粒，认为只有那些既有质子传输通道，又有连续的电子通道和气体扩散通道的胞元才产生有效的电流，而其余胞元不产生电流，把电极的输出电流转化成一个概率事件。
