With the help of regional forces, the Western literature is described as a "otherness", with super tempo-spatial abstractness and idealism, which provides a transcendental and critical dimension, and thus special aesthetic styles and artistic works. Due to the overemphasis to spirituality and idealism, with more or less the away-from-the-reality complexity, the Western literature plunges into the crisis of fixness, typicality and formularization in creation.

Instead of using a single term vector as event representation, the terms into four semantic classes are split(names, temporal expressions, spatial terms and contents) according to the semantic diffirence of them, form four vector spaces, and process and weigh the classes separately.

該方法沒(méi)有使用傳統(tǒng)向量空間模型中的單個(gè)向量丁香花高清在线观看，而是按照語(yǔ)義將特征詞劃分為4個(gè)組（人物，時(shí)間美女艹网站免费，地點(diǎn)日本三级片网黄色，內(nèi)容）并形成4個(gè)向量空間，每個(gè)空間進(jìn)行獨(dú)立的權(quán)重計(jì)算和相似度計(jì)算欧美pAAAA片。

In the device, a four-post frame was adopted, two synchronously rotating grip holders were used to realize rigidity rotation of the specimen, and the axial movement of the upper grip holder implemented the tension/compression loading. Positioning accuracy in the axis, radial and circumferential directions were achieved by adopting many advanced and delicate technologies. Measurement on the device indicated that the actual positioning accuracy of the device was better than the kinematic positioning accuracy. Evaluation test on the system indicated that the spatial resolution is better than the pixel size without considering the noise.
