In this thesis, the research and the development of electromagnetic safety materials have been reviewed. On the basis of the theory of the electromagnetic field, the electromagnetic wave and the interaction between the materials and the electromagnetic wave, several kinds of new composites have been prepared by adopting new methods, electroless plating and a kind of method of Fe replacement chemical aggradation, and studied by advanced measuring and analyzing components.

对电磁防护材料的国内外研究现状进行了研究，从电磁场与电磁波理论及电磁波与材料之间的交互作用出发，采用新的思路和方法，采用化学镀和一种Fe置换化学沉积法制备了新型的电磁防护材料，并采用先进的测试分析手段研究了材料在2～18GHz电磁波频段范围的电磁波吸收性能和在100KHz～1.5GHz电磁波频段范围的电磁波屏蔽性能。

In contrast with plasma exchange, IAS — or IgG apheresis — uses columns that bind human IgG.

Stumvoll指出，SLE治疗与免疫抑制疗法一样，最后的目标皆希望能够对自体抗体的形成作干扰；相对於血浆的置换，IAS或IgG的消除皆是使用层析管柱来吸附人体的IgG；如此即可几乎全部清除掉循环IgG及免疫复合物，不同於血浆蛋白的去除，如此即不须以新鲜冷冻的血浆或蛋白素作替换。

Based on the physical meaning of each term in the linear parameter log I (a constant correlating the affinity of solut e t o stationary phase) of stoichiometric displacement model for retention o f solute, the thermodynamic characteristics of log I of solute in revers ed-phase liquid chromatography were investigated theoretically. This poi nt was tested by experimental data with two linear relationships:(1) plot of log I vs 1/T with apolar, polar small solut es and proteins;(2) plot of log I vs log Po/w (partition co effi cient of solute between n-octanol and water) with apolar and polar smal l solutes.

依据液相色谱中溶质计量置换保留模型及线性参数log I(与1 mol溶质对固定相的亲和势大小有关的常数)，通过作图得知非极性和极性小分子溶质及生物大分子的log I与绝对温度的倒数1/T，以及小分子溶质的log I与其在正辛醇-水中分配系数的对数log Po/w呈线性关系，从两方面进一步证明了log I具有热力学平衡常数的性质。

Chapter two elaborates on the basic characteristic transformation of domestic entertainment culture since 1990 from a culture study perspective. As the most typical form of contemporary culture, the entertainment culture has displayed its conversional characteristics as the replacement of stereotypes by the reality, the deconstruction of elitism by the commonality, the subversion of sublimity by the cannibalization and the transcendence of spirit-oriented by physical-oriented.

第二部分：从文化学角度阐释20世纪90年代以来国内娱乐文化表现出与传统迥异的根本性变化与特征转换，尤其表现在平民化对精英化的解构，狂欢化对庄重化的颠覆，身体化对人格化的悬搁，以及模式化对个性化的置换；转型期的娱乐文化因此呈现出不同的文化表征。
