1.引言
新课改实施整整十个年头了,我们不妨深入教学一线看一看,题海战术、填鸭式教学、科学探究流于形式、学生学习积极性不高依然屡见不鲜.笔者认为这是由于大家不重视对物理美学的研究、忽视物理美学的作用所造成的.在此,笔者想就物理美学的研究现状与发展趋势谈谈自己的看法.
2.物理美学的研究现状
对此问题,笔者试从国外和国内对物理美学的研究现状进行阐述. 相似文献

根据国家对民族院校少数民族类学生人数占总人数的比例规定,民族院校在招生时的两个分数线,导致在一个班内学生之间成绩、水平相差较大。为了解决上述学习成绩之间得矛盾和实验仪器的短缺问题,培养学生学习兴趣,开发学生创新思维,让学生更有效的学好大学物理实验这门课程,我们提出民族院校大学物理多层次教学模式。 相似文献

The principle of an a priori use of symmetries is proposed as a new approach to solving nonlinear problems on the basis of a reasonable complication of mathematical models. Such a complication often causes an additional symmetry and, hence, opens up possibilities for finding new analytical solutions. The application of group analysis to the problems of nonlinear acoustics is outlined. The potentialities of the proposed approach are illustrated by exact solutions, which are of interest for wave theory. 相似文献

The Superconducting Radio Frequency(SRF) system of the upgrade project of the Beijing Electron Positron Collider(BEPCII) has been in operation for almost 8 years.During operation,many problems have been encountered,such as excessive heating of the power couplers,frequent beam trips during high intensity colliding,false arc interlock trigger and so on.Among them,some has been solved successfully,some have been alleviated.This paper will describe some experiences with BEPCII SRF system operation,including the symptoms,causes and solutions of problems. 相似文献

基于改进布谷鸟算法反演瞬态热传导问题随温度变化的导热系数.采用Kirchhoff变换将非线性热传导问题转换为线性热传导问题,使用边界元法求解瞬态热传导正问题.将导热系数的反演转化为函数表达式中未知参数的反演,使用改进布谷鸟算法求解未知参数.与共轭梯度法相比,改进布谷鸟算法对迭代初值不敏感;与布谷鸟算法相比,改进布谷鸟算法迭代次数大大减少.数值算例表明对改进布谷鸟算法,增加测点数量迭代次数增加;增加鸟巢数量迭代次数减少;减小测量误差计算结果更精确,同时迭代次数更少.数值算例验证了改进布谷鸟算法反演导热系数的准确性和有效性. 相似文献

Prevalence of voice problems in teachers 总被引:1,自引:0,他引:1
Teachers are frequently cited as experiencing a high rate of vocal dysfunction (1–7). Despite considerable research in the area of voice problems in teachers, the prevalence of voice disorders in this group is unknown. This study investigated the prevalence of self-reported voice problems in teachers using a mail survey of a simple random sample of 1168 state school teachers (preschool-Grade 12) in South Australia. As part of the survey, teachers were asked to report voice problems for the day of the survey, during the current teaching year, and during their careers. The response rate was 75%, with 16% of teachers reporting voice problems on the day of the survey, 20% reporting problems during the current teaching year, and 19% reporting problems at some time during their career. Females were twice as likely as males to report voice problems. These findings clearly indicate a need for further investigation of the causes of vocal dysfunction in teachers and for the development of educational programs aimed at preventing voice problems in this group of professional voice users. 相似文献
