智能的体操 教育的手段     

Η.Β.克罗言乌斯  Ε.С.格尔逊斯基  周可福 《教育学术月刊》1988,(1)

文化发展的历史有力地证明,人类对象棋的兴趣不断提高。近几个世纪以来它吸引了成千上万的爱好者。有关象棋的书有上万种,各国出版的杂志也不下千种。世界各地这种古老娱乐的爱好者们都以浓厚的兴趣注视着每场比赛。许多杰出的政治家、军事统帅、作家、音乐家、学者认为下象棋不仅是休息和消遣,而且是一种独特的智能体操,也是培养性格的有效方法。苏联学校利用象棋的大量实践,对其他国家的教育家和体育教练工作经验的分析,充分证实了利用象棋来培养、教育各种年龄的学生,开发他们的智力的巨大可能性。因此,毫无  相似文献   

职业教育——哲学和理论的阐述     

M.H.弗朗斯  张伟远 《教育与职业》1986,(5)

引言 职业教育理论只是最近才发展为一门学科,它正如人们所称的处于类似青春期的阶段(Crites,1981)。然而,最近几年已经有了不少进展。如果我们要在学校中推行一种有效的职业教育计划,就必须对职业教育理论有所了解。 在考察职业教育理论中,我们必须考虑到某些限制因素。首先,不同理论的许多假设是试验性的;第二,现存的研究中许多是依据对中层男性白人的研究资料(Herr,1970);第三,职业发展理论不能作为所有职业教育和咨询计划的一般发展理论之基础(Tolbert,1980)。  相似文献   

Hybrid heuristic and mathematical programming in oil pipelines networks： Use of immigrants     

DELACRUZJ.M. HERRAN-GONZALEZA. RISCO-MARTINJ.L. ANDRES-TOROB. 《浙江大学学报(A卷英文版)》2005,6(1):9-19

We solve the problem of petroleum products distribution through oil pipelines networks. This problem is modelled and solved using two techniques: A heuristic method like a multiobjective evolutionary algorithm and Mathematical Programming. In the multiobjective evolutionary algorithm, several objective functions are defined to express the goals of the solutions as well as the preferences among them. Some constraints are included as hard objective functions and some are evaluated through a …  相似文献   

基于红外图像的绝缘子高温区域特征研究     

宫政  西日艾力.吾斯曼  罗俊  尹迪晖  闫书佳 《教育教学论坛》2019,(1):104-105

绝缘子故障会引起表面温度的上升,造成局部区域高温。因此,准确识别绝缘子的高温区域是故障检测的有效途径。本文提出了基于灰度共生矩阵的绝缘子高温特征提取方法。红外图像经过图像分割后,提取纹理特征,选取能量、熵、惯性矩和相关性作为特征值。试验结果验证该方法准确性高,可为绝缘子高温区域的识别提供参考。  相似文献

Effect of boundary conditions and convection on thermally induced motion of beams subjected to internal heating     

MALIK Pravin KADOLI Ravikiran GANESAN N. 《浙江大学学报(A卷英文版)》2007,8(7):1044-1052

Numerical exercises are presented on the thermally induced motion of internally heated beams under various heat transfer and structural boundary conditions. The dynamic displacement and dynamic thermal moment of the beam are analyzed taking into consideration that the temperature gradient is independent as well as dependent on the beam displacement. The effect of length to thickness ratio of the beam on the thermally induced vibration is also investigated. The type of boundary conditions has its influence on the magnitude of dynamic displacement and dynamic thermal moment. A sustained thermally induced motion is observed with progress of time when the temperature gradient being evaluated is dependent on the forced convection generated due to beam motion. A finite element method (FEM) is used to solve the structural equation of motion as well as the heat transfer equation.  相似文献
