Secondly, relations between the structuralism and physics teaching illustrate that the physics history can play the role of "advanced organizer" in improving the transfer ability. Moreover, the theory of recapitulation of physics announces the inherent similarity between the process of physics research and the process of physics conception learning. According to constructivist learning theories, the dissertation explains the process of students' learning the scientific concepts.

首先论文通过分析比较皮亚杰认知发展论和库恩科学发展论得出教育实践应与科学发展规律保持一致，应重视物理学史在物理教学中的应用，对于不同认知水平的学生和不同类型的知识应采用不同的教学方法：其次从结构主义与物理教学的关系说明物理学史在提高迁移能力上可以扮演"先行组织者"的角色；再次，通过物理文化重演理论揭示人类研究物理学的过程与学生学习物理概念的过程的内在相似性，并根据建构主义学习理论解释学生学习科学概念的过程。

Also this paper gives a definition of quantum conditional entropy of entanglement E_ A｜Band proves that it satisfies the four fundamental conditions of a entanglement measure for a kind of mixed state of 2×2 quantum system by this negative quantum conditional entropy Using conditional entropy of entanglement,this paper investigates the quantum entanglement between the two identical two-level atoms simultaneously interacting with vacuum cavity field as an application.

Magnetic properties of a series of Cd1-xMnxSe quantum dots with different sizes and Mn concentrations were measured by using superconducting quantum interference device magnetometer. The field dependent magnetization of the Cd1-xMnxSe quantum dots at 2 K was obtained and it was identified not to be dominated by CdSe quantum dots but Mn ions.

我们利用超导量子干涉仪量测不同尺度(D = 5 nm， 8 nm)及不同Mn浓度(x = 0.375%， 0.75%， 1.5%)的Cd1-xMnxSe奈米颗粒磁性；我们推测在温度2 K下，所量测的磁化强度是由Mn原子贡献而非来自奈米颗粒，拟合其磁化强度对磁场曲线图而得出样品中Mn原子个数，同时假设Mn离子的磁性行为高达室温仍满足Brillouin function和Curie顺磁定律，所以可从高温的数据扣除Mn的顺磁贡献。

The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.
