Lunar regolith simulations with discrete element method based on Chang'E-5 mission's lunar soil particle morphology WANG Siyuan, JIANG Mingjing Graphical Abstract Abstract To align with the current strategic planning of "survey, mining, and development" in China's lunar exploration mission, and ...
In one such study, focused on the beneficiation of ilmenite from a synthetic lunar soil, ilmenite was found to report to both positive and negative electrodes in binary mixture separations depending on the gangue mineral chosen for the feed mixture (Li et al., 1999). When the full synthetic ...
Provenance of KREEP and the exotic component - Elemental and isotopic studies of grain size fractions in lunar soils Sieve fraction analyses of lunar soils reveal the presence of a fine-grained exotic component enriched in K, Rb, Sr, Ba, and in radiogenic Sr in all soils... NM Evensen,VR...
The last part of this series on particle characterization deals predominately with the measurement of external or internal surface areas of, and the pore size distributions in, solids and compacts by permeametry, diffusional flow, physical adsorption and mercury infiltration methods. 年份: 1977 收藏...
Abstract The morphology of granular materials, such as sands, is of significant importance due to the effect of grain shape on their physical, mechanical, and hydraulic behavior. As technology has progressed from visual identification to modern computer-based techniques, numerous methods have been deve...
We have measured the particle size distribution of lunar soil 10084,2005 in water, using a Microtrac(TradeMark) laser diffraction instrument. Details of our own sieving technique and protocol (also used in [11]). are given in [4]. While sieving usually produces accurate and reproducible results...
The size distribution of the lunar particles has been determined on Apollo 11 soil sample 10084, 1998. Scanning electron microscopy (SEM) was utilized to photograph areas of particle dispersion, and to measure the areas and diameters of the particles. The specific process for the SEM sample ...
From the late 1960s until now, lunar soil particle size distributions have typically been determined by sieving sometimes dry, and at other times with fluids such as water or Freon. Laser diffraction instruments allow rapid assessment of particle size distribution, and eventually may replace sieve ...
Based on the analysis results of components and the particle diameter distribution of lunar soil, some basalt particles with different diameters are mixed into homogeneous soil to simulate the drilling process and particles conveying condition. Lunar soil containing basalt particles with different diameters...
