Bulk density formula is given as: {eq}\gamma =\frac{m_d}{v_t} {/eq} where m_d is the mass of the dry soil and v_t is the total volume of the sample. Gamma is the bulk density that can be measured by many units, such as The SI unit: kg/m^3 pcf or pound per cubi...
摘要: 1.1本试验方法包括在压实或松散条件下测定骨料的体积密度("单位重量"),以及基于相同测定的细骨料,粗骨料或混合骨料的计算空隙率.本试验方法适用于不超过6英寸的骨料.(150 mm)标称最大尺寸. 注1-单位重量是用于描述本试验方法确定的特性的传统术语,即单位体积重量(更准确地说,是单位体积质量或密度). 1.2以...
Correction of Bulk Density and Sampling Method Biases Using Soil Mass per Unit Area 来自 国家科技图书文献中心 喜欢 0 阅读量: 68 作者: SB Wuest 摘要: This study compared the linear depth from the soil surface vs. equivalent sample mass for interpreting soil water content and concentration ...
For the first-principles calculations, crystal structural relaxations and prop- erty calculations were performed using density functional theory within both generalized gradient approximation (GGA) and local density approximation (LDA) as implemented in the CASTEP code56. Both ultrasoft (U) and norm- ...
The use of Mg-based metallic glasses is not just limited to the biomedical field; owing to the low-density feature, it can also be used as a lightweight component in defense, aerospace and automotive industries as well[14]. Yet, one thing that limits its extensive use in these industries...
a. Density plot of 42,010 tumor epithelial cells from 5 cohorts in iCMS metagene space. The mode at the bottom right of the scatterplot corresponds to iCMS2 cells, while the opposite mode corresponds to iCMS3. b. UMAP visualization of 42,010 tumor epithelial cells from 5 cohorts in trans...
Bulk density and tapped density of powders — pronounced preferred orientation effects ; — the phase has not been filed in the database used ; — formation of solid solutions ; — presence of disordered structures that alter the unit cell ; — the specimen comprises too many phases ; — ...
