作者 姚雪理 《丽水学院学报》 2005年第5期101-103,共3页
通过对高中生数学应试心理归因的调查,探讨高中生数学应试的心理归因方式。从被调查的340名学生中选出两组进行比较:甲组是数学平时成绩较好者68人,乙组为数学平时成绩较差者75人。通过对21个项目的调查结果显示:(1)学生在数学应试这一... 通过对高中生数学应试心理归因的调查,探讨高中生数学应试的心理归因方式。从被调查的340名学生中选出两组进行比较:甲组是数学平时成绩较好者68人,乙组为数学平时成绩较差者75人。通过对21个项目的调查结果显示:(1)学生在数学应试这一无法改变的事实面前大都作否定的、自身的、消极的、持久的归因;(2)对应试结果大都作封闭的、回避的、视角转换进行自我保护的归因。 展开更多

In this paper, many factors restricting and affecting the actual effectiveness of course ethnic theory and policy are summarized, among which student factors mainly include unavailable major foundation, new strange course, and having no idea about how to learn in the short term, narrow knowledge scope because of the examination-oriented education, poor self-control ability and attitude toward learning, and difference among the students of different minorities in the preparatory education, so that the actual teaching effectiveness is different. The teaching contents provided by teachers are not enough scientific, and the teaching pertinence is not strong; all parts of teaching and especially the effectiveness of processing the key and difficult points are not good enough, so that students are guided not very well to actively participate in classroom teaching activities, etc. Subsequently, an analysis is made around integrating and excavating teaching materials, understanding teaching contents, valuing the teaching process, and helping the students of preparatory education change from passively learning knowledge to initiatively accepting knowledge in a targeted way, and then some approaches, methods, and strategies of improving the actual teaching effectiveness of the course are explored. 展开更多

In order to compensate for limitations of microscopic study on loess triaxial tests, taking the loess in Longxi area as an example, the authors established the loess triaxial test model by using PFC3D software and simulating tfiaxial shear test under the different confining pressures in 0 kPa, 50 kPa and 300 kPa. Compared with laboratory triaxial shear test, the numerical simulation test has a guiding role in loess mechanical strength analysis. 展开更多

In order to achieve greater pressure ratios, compressor designers have the opportunity to use transonic configurations. In the supersonic part of the incoming flow, shock waves appear in the front part of the blades and propagate in the upstream direction. In case of multiple blade rows, steady simulations have to impose an azimuthal averaging (mixing plane) which prevents these shock waves to extend upstream. In the present paper, several mixing plane locations are numerically tested and compared in a supersonic configuration. An analytical method is used to describe the shock pattern. It enables to take a critical look at the CFD (computational fluid dynamics) steady results. Based on this method, the shock losses are also evaluated. The good agreement between analytical and numerical values shows that this method can be useful to wisely forecast the mixing plane location and to evaluate the shift in performances due to the presence of the mixing plane. 展开更多
