固态能带理论用来计算半导体介质的吸收与增益。 - Physics of solids i provides an introduction to the basic concepts of the quantum theory of solids . this website features comprehensive problem sets
固态物理提供一个固态量子理论的基本观念的简介。本网页提供了相当深入的作业习题。 - The photo - induced phase transition of the different light intensities , photo - energies and directions of the polarized light is investigated . it suggested that the photo excites the down spin eg electrons and destroys the spin order system of the thin films . the relation between the he - ne laser reflectivity of the thin film , applied current and resistance was analyzed by the optics theory of solid state physics
光子通过激发e _ g向下电子的跃迁，从而改变材料自旋极化方向，影响体系的输运行为；首次研究了cmr薄膜的激光反射率和偏置电流的关系，并用固体光学理论对其定性分析，表明反射率的变化是由于电场引起材料的晶格畸变，改变了极化率，从而导致材料的折射率和反射率发生改变。 - The following results are achieved : ( 1 ) in accordance with the empirical electron theory of solids and molecules , considering the number of covalent bond pairs on the strongest bond in a segregation structure na , the elements for matrix - strengthening can be chosen . ( 2 ) on the basis of the available phase - equilibrium thermodynamics calculation of alloy system and phase diagrams , which have been worked out , the contents of alloy elements can be identified with reference to the types , quantity and phase - transformation of carbides . ( 3 ) both the values relating to toughness ( including bending strength , yield strength , impact value of unnotched samples ) and hardness of new dm9 die steel are higher than those of crl2mov die steel
结果得出： ( 1 )根据固体与分子经验电子理论，利用偏聚结构单元的最强共价键上的共用电子对数n _ a ，可以选择工模具钢基体相的强化元素； ( 2 )根据合金系相平衡热力学计算及已有的相图，可以碳化物类型、数量及其相变确定合金元素含量； ( 3 )新型dm9钢在强韧性(抗弯强度、屈服强度、无缺口冲击值)和硬度方面均高于cr12mov钢； ( 4 )以dm9钢与6crw2si 、 7cr2wmovsi ( dm7 ) 、 h13和cr12mov四种模具钢的实验比较，进一步验证了上述冷作模具钢合金设计方案是合适的。
