面具下的荒诞——《路的尽头》之真相

约翰·巴思是当代美国最有影响力的后现代主义小说家之一,他的第二部作品《路的尽头》充分讨论了＂面具＂的深刻含义。人格面具是一把双刃剑：它是人适应社会的重要条件,但在整个人格中也会产生负面影响。运用面具理论,分析小说中主人公雅各布·霍纳错综复杂的思想,探讨人格面具对他生活所造成的影响;分析导致霍纳人格面具膨胀和人格分裂的深层社会原因。可以发现,巴思正是试图通过借助霍纳所戴的面具,嘲讽当时虚无、荒诞和存在焦虑的社会思潮。     

Continuity of solution mappings for parametric generalized set-valued weak vector equilibrium problems

This paper obtains some stability results for parametric generalized set-valued weak vector equilibrium problem. Under new assumptions, which do not contain any information about solution mappings, the authors establish the continuity of the solution mapping to a parametric generalized set-valued weak vector equilibrium problem without monotonicity. These results extend and improve some results in the literature. Some examples are given to illustrate the results.

Design of the signal processor for an ionospheric sounding system

On the basis of the analysis of the system sounding principle, this paper introduced a new type of ionospheric oblique backscattering sound system, which is based on the pseudo- random noise phase modulated pulse compression. According to the high requirements of real-time and a large amount of computation and echo characteristics, a high-speed real-time signal processing system was established and the design of system hardware and software was focused on. The sounding results indicate that the system is equipped to handle the data fast and has a high degree of software features. It is of great significance for the realization of fast, real-time ionospheric sounding means.

K148与K149对黑曲霉NRRL3135植酸酶A与植酸结合机制的影响

为了研究黑曲霉NRRL3135植酸酶A K148与K149对底物与酶的结合反应的影响,构建了一个单位点突变体(K148E)和一个双位点突变体(K148E和K149E),由于带电的氨基酸残基发生变化,造成这2个突变体的酶活性都有不同程度的减少,利用InsightII软件模拟了2种突变体酶的3-D结构,发现酶分子突变位置的表面电势有明显的改变.这2个α-螺旋(141～160)位点的改变可能降低了活性中心附近的底物浓度,减缓了底物与活性中心的反应速度.     

薄板冷轧过程中宽展的变化规律及其影响因素

基于金属流动原理,采用显式动力学有限元软件ANSYS/LS-DYNA模拟薄板轧制过程,研究轧制力、摩擦系数、压下率对轧件宽展变化的影响。结果表明,摩擦系数越大,轧件宽展也越大;轧件的最大宽展随着轧制力的增加而增大,轧制力对轧件后端部分宽展影响程度较大;压下率增大,轧件宽展随之增大,轧件各部分宽展的不均匀程度也在增加。     

氧化镍掺杂酚醛树脂热解炭的结构及抗氧化性研究

在酚醛树脂中直接掺杂三氧化镍粉末,研究氧化镍掺杂量、炭化温度对氧化镍改性树脂热解炭结构和氧化温度的影响。用X射线衍射、拉曼光谱、扫描电镜和综合热分析等手段对氧化镍改性树脂热解炭的石墨化度、显微结构及氧化温度进行表征。结果表明,埋炭条件下掺杂三氧化二镍,450～750℃温度下被逐级还原成一氧化镍和单质镍,其催化热解炭形成晶须、片状或块状结构;氧化镍改性树脂热解炭石墨化度随炭化温度升高和氧化镍掺杂量增加而增高,其氧化温度高于酚醛树脂氧化温度;氧化镍的最佳掺杂量为3%～5%。     

Sequence similarity analysis of non-self CTL epitopes and mouse proteins using sequence alignment

This research analyzed amino acid sequence similarity between non-self T cell epitopes recognized by mouse antibodies and mouse proteins. Using sequence alignment,we found that only 8 of 1 108 epitopes are highly similar to mouse protein sequences. The result shows that non-self T cell epitopes are not similar or have little similarity to mouse protein sequences. Furthermore,reviewing the related literature,we also found that the eight epitopes would trigger immune responses in some particular environment,which are ignored by T cells in normal condition. The result suggests that no or low-similarity peptide vaccines can reduce the chance of collateral cross-reactions and enhance the antigen-specific immune response to vaccine.
