By using quantum mechanical wave impedance matching, we study the ballistic propagation of a quasionedimensional noninteractingelectron gas through quantum box, in which the electrons are free except for their interaction with the boundaries. The ballistic conductance of a box is calculated as a function of its width and length. When the length is shorter, the conductance showes certain quantized step with some regular pulse oscillations. However, as the length is increasing, it becomes as the pattern...

The material with electromagnetic wave absorption function is an important military stealth material. Its physical mechanism is that it interacts with electromagnetic wave and the wave energy is changed into heat or other energy as much as possible. The important parameters for the wave absorption effects are electromagnetic loss factor, complex dielectric constant, complex magnetic conductivity. From simple equivalent electric circuit, the absorption mechanism of the material is analyzed ,the physical meaning of these parameters is explained and the design direction of the material is put forward qualitatively.It is illustrated from the results that the electromagnetic wave loss mechanisms are divided into resistance loss, dielectric loss, and magnetic loss. Both this losses and wave impedance matching are considered for design of the material. A good way to realize the goal of light weight, strong absorption, wide frequency band, absorbing microwave and infrared ray compatibly and other fine properties for the material is that it is made by more components composite especially nanoparticle polymer composite, combing three types′ losses and impedance matching. It is necessary that the absorption property is studied in microcosmic with solid state quantum mechanics to solve the problem of material design in theory.

Transmitting from one material to another, wave will reflect and refract in the interface due to different wave impedance matching. Wave energy will reflect and refract, too. The energy along with reflected wave into the primary material is called reflected energy, and the energy along with refracted wave into another material is called refracted energy. Based on the theory of the transmission of reflected wave and retracted wave at interface, the transmission (including reflection...

Transmitting from one material to another, wave will reflect and refract in the interface due to different wave impedance matching. Wave energy will reflect and refract, too. The energy along with reflected wave into the primary material is called reflected energy, and the energy along with refracted wave into another material is called refracted energy. Based on the theory of the transmission of reflected wave and retracted wave at interface, the transmission (including reflection and refraction) of explosion energy is analyzed and the calculating method on the rate of reflection and refraction of explosion energy and the relationship of the best impedance matching between rock and explosive are established. In addition, the influence of different kinds of charging structure(coupling charge, decoupling charge with air and decoupling charge with water) on explosion energy transmission is discussed, so that different kinds of charging structure can be applied for different engineering blasting.

波从一种介质向另一种介质传播时,由于波阻抗不同,将在界面处发生折射和反射,彼所传递的能量也会随之发生相应变化,随反射波反射到原介质中的能量称为反射能量,随折射波折射到另一介质中的能量称为折射能量。首先,根据波的界面折射和反射理论,分析爆炸能量的折射和反射规律,建立爆炸能量折射率和反射率的计算公式以及岩石和炸药的最佳阻抗匹配关系;然后,据此探讨不同炮孔装药结构(耦合装药、空气不耦合装药、水不耦合装药)对爆炸能量传递的影响,以期提出适用于不同爆破要求的合理装药方式。
