素质教育的重点内容之一是创新教育,即培养学生的创新素质.创新素质除了包括创新思维能力,创新实践能力等智能素质外,还包括创新活动中表现出来的自觉性、坚韧性、果断性、自制力等良好的个性心理品质.如何培养学生的创新素质是当前教学研究的重要课题.物理学是一门以实验为基础的科学,如何在物理实验中培养学生的创新素质,也成为广大物理教育工作者关心和研究的热点.对中学物理实验的创新研究,由低到高大致可以分为三个层次:一是实验局部改进;二是实验思想更新;三是实验内容创新. 相似文献

中科院院长路甬祥认为:“21世纪将是人类依靠知识创新和高技术创新持续发展的时代”,不少国家对高等教育发展趋势的研究也表明,在人才培养上要更加注重能力、素质的培养,特别是创新能力的培养。现在提倡的素质教育,其核心内容就是创新人才的培养。要求创新人才要有创新的意识、创新性的思维和创新的能力。要培养大学生的创新能力,作为老师,教学思想、教学内容和教学方法也要创新。近年来,我们结合物理学和电子学专业的特点,通过教学实践,围绕创新教育作了一些探索。 相似文献

创造思维是创新人才的基础素质,培养创新人才的核心就是要培养学生的创造思维,而实验教学则是培养学生创造思维的最佳载体.但初中物理实验教学的现状不利于创新人才的培养,故急切呼唤实验教学的改革.让学生在改革中培养发散思维,解决思维的方向问题;培养辩证思维和纵横思维,解决思维的策略问题;培养直觉思维、形象思维和逻辑思维,解决思维的主体问题.从而在学生的头脑中形成一个优化的创造思维结构,为创新人才的脱颖而出营造一个良好的科学环境. 相似文献

在信息技术和知识经济的今天,创新已成为民族振兴的关键,国家兴旺的基石。创新教育是现代教育的灵魂,要培养勇于创新的综合型人才,在现代教育中实施创新教育已成为人们的共识。而创新能力的培养,教育起着举足轻重的作用。物理作为一门实验科学,在教学中应有意识加强学生的创新意识和创新能力的培养。一、激发学生创造动机,唤起强烈的创新意识消除创新的神秘感,明确物理学本身发展即创新过程创新意识是指学生具有引起某种创造动机所表现的创作意向和愿望的意识。创新意识是创造性思维和活动的基本前提和条件。一个人如果没有创新欲望和动机,就不可能去进行创新性思维和创新活动。 相似文献

A spherical compact matched load, for high vacuum operation suited for short pulses (2 MW, 0.1 s) precise measurement has
been designed to test high power gyrotrons Bruschi, Gandini, Muzzini, Spinicchia, Cirant, Gittini, Granucci, Mellera, Nardone,

for high power millimeter-wave Beams, 23rd Symposium on Fusion Technology, September 20–24, 2004, Venice, Italy). In order
to enhance the power handling capability of the load and to reduce the operation problems that may arise from an excessive
reflection from the load, a ray tracing code has been written to model the power distribution on the inner surface and the
pattern of the reflected radiation. The outcome of this code has been used to select a more convenient profile for the spreading
mirror of the load and to optimize a pre-load specially conceived to minimize the power reflected fraction. 相似文献

A method of the atomic-emission spectrum analysis of soil has been developed for control of the accumulation of technogenic
impurities in environmental objects. A sample, after calcination at 550°C, is evaporated in an arc discharge. Spectra are
recorded by a DFS-8 spectrograph. Simultaneously, determination is made of Li, Ba, Sr, Cu, Zn, Cr, Ni, Co, Pb, Bi, Mo, V,
Ge, Ga, Y, Nb, Sn, Cd. For the majority of the elements the detection limits are lower than their percent abundance in the
crust and their maximum permissible concentrations.

Due to the drawbacks in Support Vector Machine(SVM)parameter optimization,an Improved Shuffled Frog Leaping Algorithm(Im-SFLA)was proposed,and the learning ability in practical speech emotion recognition was improved.Firstly,we introduced Simulated Annealing(SA),Immune Vaccination(Iv),Gaussian mutation and chaotic disturbance into the basic SFLA,which bManced the search efficiency and population diversity effectively.Secondly,Im-SFLA Was applied to the optimization of SVM parameters,and an Im-SFLA-SVM method Was proposed.Thirdly,the acoustic features of practical speech emotion,such aS ridgetiness,were analyzed.The pitch frequency,short-term energy,formant frequency and chaotic characteristics were analyzed corresponding to different emotion categories,and we constructed a 144-dimensional emotion feature vector for recognition and reduced to 4-dimension by adopting Linear Discriminant Analysis(LDA) Finally,the Im-SFLA-SVM method Was tested on the practical speech emotion database,and the recognition results were compared with Shuffled Frog Leaping Algorithm optimization-SVM(SFLA-SVM)method,Particle Swarm Optimization algorithm optimization-SVM(PSo-SVM) method,basic SVM,Gaussian Mixture Model(GMM)method and Back Propagation(BP)neural network method.The experimentM resuits showed that the average recognition rate of Im-SFLA-SVM method was 77.8%,which had improved 1.7%,2.7%,3.4%,4.7%and 7.8%respectively,compared with the other methods.The recognition of fidgetiness was significantly improve,thus verifying that Im-SFLA was an effective SVM parameter selection method,and the Im-SFLA-SVM method may significantly improve the practical speech emotion recognition. 相似文献
