中级水平留学生对部件熟悉的陌生形声字的语音提取

本文采用纸笔测验方法探讨了中级水平留学生对部件熟悉的陌生形声字的语音提取特点。结果表明,字的类型、声旁位置和形旁可命名性影响中级水平留学生对部件熟悉的陌生形声字的语音提取,具体表现为:规则字的命名成绩好于不规则字;声旁在右的汉字命名成绩好于声旁在左的汉字,形旁不可命名的汉字命名成绩好于形旁可命名的汉字。当陌生形声字的形旁不可命名时,中级水平留学生对整字的命名更倾向于利用声旁信息;形声字声旁在右时,利用可单独命名的声旁命名整字的可能性更大;当形旁可命名时,声旁的语音线索与形旁的语音线索存在竞争。中级水平留学生对部件熟悉的陌生形声字语音提取主要采用"读声旁"、"读形旁"和"类比"三种策略,尤其以"读声旁"和"读形旁"等"读半边"策略为主。

Deformation mechanism of high-stress and broken-expansion surrounding rock and supporting optimization based on the gray correlation theory

Aiming at the large deformation and support problems of high-stress and broken-expansion surrounding rock, and taking 1 000 m level roadway of Mine II in Jinchuan as the research object, an investigation on the deformation and damage of roadway surrounding rock and an analysis of its mechanism were carried out. The gray correlation theory was used in support scheme optimization design. First, causes and mechanism of deformation of the 1 000 m horizontal transport channel were analyzed through field investigation, laboratory test and data processing methods. We arguued that poor engineering geological conditions and deep pressure increases were the main factors, and the deformation mechanism was mainly the ground deformation pressure. Second, the gray correlation theory was used to construct supporting optimization decision method in the deep roadway. This method more comprehensively considers various factors, including construction, costs, and supporting material functions. The combined support with pre-stressed anchor cables, shotcrete layer, bolt and metal net was put forward according to the actual roadway engineering characteristics. Finally, 4 support schemes were put forward for new roadways. The gray relational theory was applied to optimizing the supporting method, undertaking technical and economic comparison to obtain the correlation degree, and accordingly the schemes were evaluated. It was concluded as follows： the best was the flexible retaining scheme using the steel strand anchor; the second best was the one using plate anchors on the top and rigid common screw steel bolt on the two sides; the ttiird was; the rigid common screw steel bolt in full section of roadway; and the worst is the planished steel rigid support. The optimized scheme was applied to the 1000 m level of new excavation roadway. The results show that the roadway surrounding rock can reach a stable state after 5 to 6 months monitoring, with a convergence rate less than 1 mm/d.
