An empirical formula of electronic Stopping Cross Section, Se, for low energy ions, such as Li+, Be+, B+, C+, N+, O+, F+, and Ne+, in solid materials is established according to the experimental electronic stopping power data in solid media.
Comparison between experiment results and the data in literature demonstrates that it is a non-contact, nondestructive, rapid and exact approach to measure the thermal diffusivity of opaque solid materials.
The PSSCR performance is influenced by the content of ZnO in the Cu/ZnO-TiO2 solid materials. The solid material, 1%Cu/20%Zn-TiO2, has the best PSSCR performance and the products are crylic acid, aldehyde and CO.
A low temperature photoluminescence (PL) measurement facility connected with an IBM-PC microcomputer is set up for PL measurement of solid state materials especially for Ⅲ-Ⅴ and ,Ⅱ-Ⅴ semiconductor compounds. It is named as PL-PC and as shown in Fig. 1. The system is interfaced with a data acquisition system (DAS) , the series 500 of Keithley Company of the United States.
低温光致发光微计算机测试系统(PL-PC)是应用IBM-PC微计算机和先进的具有软件的数据采集系统(Keithley DAS Series 500)等配接到低温光致发光测量设备上,对固体材料的光致发光进行测试.
These flows are due to the effect of the heat-release source, the propagation of perturbations induced by elements of the rigid wall, and the dynamics of conductive heat transfer in the solid material.
This model includes the heat- and mass-transfer and kinetic-gasdynamic processes in the gas phase above the surface of burning solid propellant, as well as the heat-transfer processes in solid material.
Distribution of macro-and microelements, found in precipitation in dissolved and suspended forms (solid material) is considered.
In VIB theory, the solid material is considered to consist of random-distributed material particles in microscale.
The tensile slrength of the bond between water and solid material is the predominant parameter.
The distribution of strongly magnetic nodules in soils and the absence of correlation between the content of magnetite and the magnetic parameters of the enclosing soil material indicate that the nodule magnetite is of soil origin.
In the case of 3D pile model the moment or couple developed by the side shear around the perimeter can be taken into account, where this moment can be significant especially in strong soil material or in the case of large diameter pile/shafts.
The result shows that many different distributions (uniform distribution, concentrated distribution and random distribution) of fractures in rock and soil material are the essential reasons of the daedal constitutive relations.
On account of α-ray emission from rocks and other soil material the ionization within the first 10 cm above ground is more intense than further up.
The examples are taken from the index sections "atomic absorption spectrometry" (method), "phenols" (substance) and "soil" (material).
