特里·伊格尔顿从文学哲学的视角探索＂文学本质＂的运作机制,认为文学作品的结构可以实现文学自身的意义,在阅读行动中的自我实现即事件,读者的阅读行为是不断重构文学事件的＂结构化＂过程。本文将《金色笔记》作为＂事件＂探寻＂文学本质＂的运作机制、文本形式的＂结构化策略＂及作品的道德空间,最后从文本、读者、作者之间的戏剧性对话中操演性解读《金色笔记》中的＂文学事件＂。

　　Ferrocene is a compound with excellent stability. In addition, it has very favourable electrochemical properties. So the synthesis, structure, electrochemistry and coordination behaviors of ferrocene-derivatives have attracted considerable attention in recent years.[1,2] Electrondonating atoms such as N, S, O in the derivatives are known for their coordination particularly with transition metals. [3] Two new bis-ferrocene-containing acyl thiourea derivatives are synthesized. The derivatives are confirmed by IR spectrum, 1H NMR and elemental analysis. These compoundshave many electrondonating atoms and two ferrocenes. The structure of one compound is shown below. The study onelectrochemistry and coordination behaviors is in the progress.……

提出了对基于扫描激光器的光纤布拉格光栅(FBG)传感系统进行掺铒光纤(EDF)/双波拉曼混合放大的方法,大幅度提高了该光纤布拉格光栅传感系统的传输距离。该方法以高功率扫描激光器作为光源,采用双波长拉曼放大的方法对信号进行低噪声双向放大,再利用系统中间的两段掺铒光纤,将剩余的拉曼抽运功率用来产生自发辐射光和放大传感信号,使得整个系统能在超长的传感距离上获得良好的信噪比(SNR)。实验表明使用一台扫描激光传感分析仪、一只170mW的拉曼抽运和一只2W的拉曼抽运,可以使传感距离达到100km以上,并且传感系统的光纤布拉格光栅反射信号均能获得超过7dB的良好信噪比,从而实现在超长距离上的光纤布拉格光栅传感。

To prepare and characterize the ferromagnetic fluid of Fe304 modified by carboxyl PEG （FF/carboxyl PEG） for hyperthermia of tumor, the magnetic nanoparticles （NPs） of Fe304 were prepared by chemical co-precipitation method, and then modified with carboxyl PEG. The iron content of FFs was determined by spectrophotometric method using o-phenanthroline. The stability of FF/carboxyl PEG was assessed by the sedimentation method. FF/carboxyl PEG was characterized by X-ray diffraction （XRD）, transmission electron microscopy （TEM）, infrared spectrometry （IR） and vibrating sample magnetometer （VSM）. Heating effect of FF/carboxyl PEG was measured in an alternating magnetic field in vitro. The stability of FF/carboxyl PEG was much better than that of unmodified ferromagnetic fluid. FF/carboxyl PEG was proved to be composed of Fe304 by both XRD and IR. TEM showed that the ferromagnetic particles were well-dispersed. The average particle size was calculated as 5 nm by XRD. The saturation magnetization and residual magnetization of FF/carboxyl PEG were 47.01 and 3.41 emu/g, respectively. The coercive force was 6.70e. The specific absorption rate （SAR） of the FF/carboxyl PEG was 63.0 W/g[Fe]. The FF/carboxyl PEG shows the promise for hyperthermia of tumor.
