英语学习策略发展研究的回顾与展望

英语学习策略的发展是动态的过程.策略在一生中不是固定的,通过自然发展和训练而改变.本文从英语策略的自然发展和训练获得两条线索对英语策略的发展进行了一个全面梳理与总结.英语策略在自然发展上存在关键期,认知策略在学习初期,对学习作用十分明显.但随着年级提高,认知策略在学习中的作用越来越让位于其它策略.元认知策略、社会支持策略和情感策略随着年级的升高,作用越来越明显.英语策略的训练对学生成绩提高有效果,尤其对于中下水平学生效果更明显.但在策略训练中,要特别防止学生策略"利用性缺陷"的产生.     

基于有限元强度折减法分析土坡稳定

对有限元强度折减法进行了总结,并将其与ANSYS有限元程序很好的结合,通过算例,验证了这种方法在ANSYS分析土坡稳定问题时的可行性,结果表明:通过平面应变Mohr-Coulomb匹配的D-P准则与Drucker-Prager屈服准则的转化,可以求得更加符合实际的边坡稳定系数,并可以模拟出边坡的渐进破坏过程.

字字痛刻骨,一洗艳与冶—论同光体诗人夏敬观

夏敬观为同光体江西派著名诗人,专学梅尧臣,为同光体之后劲。其诗歌理论重学问,主张学古求变。诗歌抒发了对苦难现实的愤慨,诉写其内心种种错综复杂的矛盾愤慨。其诗学梅一端,格调多类香山,命意之凄苦则类孟郊, 向往“由奇造淡雅”的境界。     

热处理对桑蚕丝纤维结构与性能的影响

文章以普通桑蚕丝纤维和经壳聚糖处理的桑蚕丝纤维为研究对象,对其进行热处理,研究热作用对其结构与性能的影响.研究结果表明,两种真丝纤维经热处理后均产生失重与泛黄现象,且壳聚糖处理真丝纤维较普通桑蚕丝更明显.热处理后,普通桑蚕丝纤维结晶度提高,壳聚糖处理真丝纤维结晶度下降,同时其纤维表面出现皱缩条纹.经壳聚糖处理的真丝纤维更易老化.     

Grading Standards of the Coefficient of Variation in the Electronic Raw Silk Size Testing

In order to shorten the difference between the raw silk size grading standards of the world and that of China, to quicken the step of the electronic raw silk testing process, the distribution of the coefficient of variation （CV50m%） of the raw silk size in the electronic testing and the development of the new standards are studied according to the sampling and grading theory. By the theoretical deduction and the simulating experiments, the distribution of the coefficient of variation of the raw silk size is given, and the grading scheme whose quality index is the coefficient of variation（CV50m%）of the raw silk size and the grading precisions of all grades are proposed. Moreover, the rightness and the feasibility of the grading scheme are testified by the sampling and grading simulation.

我国体育产业投资基金发展的研究

体育产业投资基金主要是针对未上市体育企业进行直接投资的一种金融创新模式,是体育产业领域投融资体制发展过程中出现的一个新鲜产物。研究利用文献资料法、数理统计法、逻辑分析法等对我国体育产业投资基金的基本理论、发展现状和现存问题等进行了研究分析。认为我国体育产业投资基金发展时间尚短,相关立法和运作环境不成熟,与国内其他行业的产业投资基金相比还存在较大的差距。今后,我国的体育产业投资基金发展运作与改革应主要围绕健全法律体系、拓宽资金渠道、给与税收优惠、培养职业人才和完善退出机制等方面进行。     

Influence of Dilative Technology on Thickness and Fullness of Tussah Silk＇s Fiber and Fabric

In this paper, study objects are raw and dilative tussah silk. By means of measuring and analyzing the fiber＇s diameter, linear density, diameter coefficient, thickness and fullness, this paper focuses on the influence of dilative technology on tussah silk＇s fiber and fabric. The results include the following three aspects： the diameter coefficient of dilative tussah silk fiber is increased by 10.35%,dilative tussah heather silk is thicker and fabric fullness is improved by 9%.     

Improved Scheme for Probabilistic Transformation and Teleportation of Multi-Particle Quantum States

In most probabilistic teleportation schemes, if the teleportation fails, the unknown quantum state will be completely ruined. In addition, the frequently proposed high-dimensional unitary operations are very difficult to realize experimentally. To maintain the integrity of the unknown quantum state to be teleported, this analysis does not focus attention on the original multi-particle state but seeks to construct a faithful channel with an ancillary particle and a unified high-dimensional unitary operation. The result shows that if the construction of the multi-group Einstein-Podolsky-Rosen pair succeeds, the original multi-particle state can be used to deterministically teleport the unknown quantum state of the entangled multiple particles which avoids undermining the integrity of the unknown state brought about by failure. This unified high-dimensional operation is appealing due to the obvious experimental convenience.
