高职工科专业大学物理开设现状及意义研究

大学物理是理工科专业的一门基础课程，主要内容是自然界中的科学规律及基本定理，其目的在于传授学生的科学知识，提高科学素养，培养创新能力。这一课程在本科理工科专业普遍开设，但在高职工科专业中开设率并不高，使得高职学生缺乏基础物理知识，对学生的后续学习和职业发展造成一定的困难，也对职业教育的质量产生影响。因此，分析这一课程在高职开设率不足的原因尤为重要。同时，探究这一课程在高职工科专业中开设所能取得的预期效果及影响，有利于解决这一课程是否应该在高职开设的问题，改革和完善当前高职课程体系，从而提升职业教育质量和培养高技能人才。

《三度学及其测量》课程建设的探索与实践

辐射度学、光度学和色度学(以下简称"三度学")是现代光电信息转换、传输、存储、显示、测量和计量的基础,随着光电信息技术、图像技术的发展和应用的扩展,"三度学"及其测量技术已成为光电工程领域科研和应用人员必备的专业基础知识和技术,在国内还没有完全类似的教材和课程设置。以往教学中仅在某些课程中部分涉及辐射度学和光度学的概念,难以使学生全面地掌握和应用相关的知识,至于色度学则更少涉及,系统讲授的课程大多安排在研究生阶段,但也较少涉及相关的实验仪器和技术的讲授。从光电信息科学与工程类专业知识体系结构的角度出发,总结了多年教学科研的经验,探索了以"三度学"作为教学内容,通过配合相关测量的实验,开展了"三度学"课程建设的探索。     

我们的"非线性物理"课

Pressure-driven "molecular metal" to "atomic metal" transition in crystalline Ga

We present the ultrasonic study of gallium (Ga I) under high pressure up to 1.7 GPa, including the measurements of the density and elastic properties during phase transitions to Ga II and to a liquid state. The observed large drop of both bulk and shear moduli (by 30% and 55%, correspondingly) during the phase transition to Ga II, as well as the increase of the Poisson's ratio from typically "covalent" ( approximately 0.22) to "metallic" ( approximately 0.32) values, experimentally testifies to the coexistence of a molecular and metallic behavior in Ga I and to the disappearance of the "covalency" during the transition to Ga II. A high value of the pressure derivative of the bulk modulus for Ga I and the increase in the Poisson's ratio can be associated with the weakening of the covalency in compressed Ga I and considered as a precursor of the transition to normal metal.     

Observation of "Stick" and "Handle" intermediates along the fullerene road

The hypothesis that fullerenes grow in a carbon plasma by the addition of C2 units (the "fullerene road") has been widely acclaimed as the most plausible mechanism for formation of larger fullerenes including C60 and C70. Calculations suggest that the association of C2 with fullerenes proceeds through two classes of intermediates, "sticks" and "handles." Here we report the observation of these species using high-resolution ion-mobility measurements for C(n) cations generated by laser vaporization of graphite and laser desorption of C60. Sticks with up to eight-atom chains have also been found.     

Model basis states for photons and "empty waves"

From the perspective of physical realism (PR), a photon is a localized entity that carries energy and momentum, and which is surrounded by a wave packet (anempty wave) that is devoid of observable energy or momentum. In creating quantized PR basis states for a photon wave packet, three requirements must be met:(1) The basis states must each carry the frequency of the wave;(2) They must closely resemble the photon, so that e.g. they scatter in the same manner from an optical mirror;(3) They must have infinitesimal energy, linear momentum, and angular momentum. An essentially zero-energy "empty wave" quantum-a "zeron"-is defined which meets these requirements. It is created as an asymmetric single-particle (or single-antiparticle) excitation of the vacuum state, with the "particle" (or "antiparticle") and its associated "hole" (or "antihole") forming a rotational bound state. The photon is reproduced as a symmetric particle-antiparticle excitation of the vacuum state, with the "particle" and "antiparticle" also forming a rotational bound state. The relativistic transformation problem is discussed. A key point in this development is the deduction of the correct equation of motion for a "hole" state in an external electrostatic field.     

Dissociation of perceptual judgments of "what" and "where" in an ambiguous auditory scene

Whenever an acoustic scene contains a mixture of sources, listeners must segregate the mixture in order to compute source content and/or location. Some past studies have explored whether perceived location depends on which sound elements are perceived within a source. However, no direct comparisons have been made of "what" and "where" judgments for the same sound mixtures using the same listeners. The current study tested if the sound elements making up an auditory object predict that object's perceived location. Listeners were presented with an auditory scene containing competing "target" and "captor" sources, each of which could logically contain a "promiscuous" tone complex. In separate blocks, the same listeners matched the perceived spectro-temporal content ("what") and location ("where") of the target. Generally, as the captor intensity decreased, the promiscuous complex contributed more to both what and where judgments of the target. However judgments did not agree either quantitatively or qualitatively. For some subjects, the promiscuous complex consistently contributed more to the spectro-temporal content of the target than to its location while for some it consistently contributed more to target location. These results show a dissociation between the perceived spectro-temporal content of an auditory object and where that object is perceived.
