There is a need to simultaneously preserve evidence of interactions between the biological community and soil structural properties of a soil in as near an intact （natural） state as possible. Three dehydration techniques were implemented and assessed for their ability to minimise disruption of both biological and physical properties of the same arable soil sample. Dehydration techniques applied until samples were at constant weight were i） air-drying at 20℃ （AD）; ii） -80 ℃ freeze for 24 h, followed by freeze-drying （-80FD）; and iii） liquid nitrogen snap freeze, followed by freeze-drying （LNPD） and were compared to a moist control. Physical structure was determined and quantified in three dimensions using X-ray computed tomography and microbial phenotypic community composition was assessed using phospholipid fatty acid （PLPA） profiling. This study confirms that any form of dehydration, when preparing soil for simultaneous biological and physical analysis, will alter the soil physical properties, and cause some change in apparent community structure. Freeze-drying （both the LNFD and -80FD treatments） was found to minimise disruption （when compared to the moist control soil） to both the soil physical properties and the community structure and is a preferable technique to air-drying which markedly alters the size and character of the pore network, as well as the phenotypic profile. The LNFD was the preferred treatment over the -80FD treatment as samples show low variability between replicates and a fast turn-around time between samples. Therefore snap freezing in liquid nitrogen, followed by freeze drying is the most appropriate form of dehydration when two sets of data, both physical and biological, need to be preserved simultaneously from a soil core.

人们已经精确地讨论了现行的按比例放大公式,并且改进和推广了最近导入公式的一个概念,即介质旋转质量流和矿石轴向质量流的比率。对比矿石与介质的碰撞次数和具有比能常数的平均冲击能。可以说明按比例放大的磨机的相似破碎。进一步的结果是,在单元矿石停留于磨机的期间,磨机的平均转数和矿流路经的弯曲度都将显著地减少,而轴向流却随磨机直径的增加而非常剧烈地增加。当磨机直径达到临界范围时,特别对某些给矿较粗的矿石这些因素可导致磨机生产能力受限制。由于自磨机的大部分有效体积完全地或大部分地由矿石所占据,因而它们可以在相当大的直径时工作。此时额定的停留时间较长,矿流流径弯曲度较大。
