A pair of primers was designed according to the coat protein gene of Arabis mosaic viru and used to amplify a 990 bp partial gene of the cp by reverse transcription-polymerase chain reaction, the 990 bp partial gene was cloned into the pEGX-9p-1, a prokaryotic expression vector fused with GST. The recombinant vector was transformed into E. coli BL21. The fusion protein was successfully expressed in E. coli BL21 induced with the IPTG at 37℃.

依据报道的ArMV外壳蛋白基因(coat Protein， Cp)序列设计引物，通过RT-PCR 扩增得到长约990bp的ArMV cp基因亲水基团部分片段，将目的片断克隆到原核表达载体pEGX-6p-1中，构建ArMV cp基因与GST蛋白融合表达载体pEGX-cp，重组载体化大肠杆菌BL21，经IPITG诱导后，融合蛋白GST-cp得到了特异表达。

On the basis of the analysis of the scores, the author makes conclusions about the characteristics of Schubert"s last three piano sonatas as followings: 1 The device of universal development in the movements composed in sonata form and rondo-sonata form is the most distinctive feature in the last three sonatas, which is also decisive in the trend of the whole movement and makes the developments relatively "still". 2 In the device of themes, the method of irregularity is preferred. However, By using extension, abbreviation, repetition and further repetition of periods, Schubert brings those themes to ingenious balance in both architectonics and aesthetics. 3 Chain method is applied in the connection of themes, in which the previous material is taken as basis and then modified together with the variations of new materials. By this way, the theme is continuously developed. 4 The principle of the dominant-subordinate is followed in Schubert"s three-key exposition, and the process of each key is extended.

本文在详尽分析乐谱的基础上，对最后三首奏鸣曲的主要创作特点进行了以下总结： 1、奏鸣曲式和奏鸣回旋曲式乐章中展开的普遍化是最后三首奏鸣曲最为显著的特点，它决定了整个乐章的走向，并使展开部具有相对"静止"的特点； 2、舒伯特的主题写作中更喜欢运用非方整性写法，并通过自身材料的延长、缩减和重复或者更高一级的段落重复使其达到了结构上和审美上的巧妙平衡； 3、舒伯特喜欢用链式的主题贯穿方式，音乐以之前的材料为依据，经过变化后再加入新的材料，用这种方式不间断地发展； 4、舒伯特的三调呈示部遵循从主到属的总体原则，并扩展了调性历程。
