Porosity, английский
- Porosité
- The ratio of pore volume to total volume of a filter medium expressed as a percent.
- A ratio, usually expressed as a percentage, of the volume of voids in a material to the total volume of the material, including the voids. the voids permit gases or liquids to pass through the material.
- The ratio of the pore volume of a rock to its bulk volume, usually expressed in percent of the bulk volume.
- Пористость, пустотность
- The ratio of the volume of air or void contained within the boundaries of a material to the total volume (solid matter plus air or void) expressed as a percentage.
- The ratio of the volume of voids in a rock or soil to its total
- The ratio of the aggregate volume of pore spaces in rock or soil to its total volume, usually stated as a percent.
- Random pits or holes in the object.
- Discontinuity in metal resulting from the creation or coalescence of gas. very small pores open to the surface are called pinholes.2,5
- Discontinuity in metal resulting from the creation or coalescence of gas. very small pores open to the surface are called pinholes.
- The condition of being porous (such as a rock formation).
Porosity, английский
Porosity coefficient, английский
Porosity sample, английский
A sample for which the porosity or ratio of the volume of all pore space to the total bulk volume of the sample may be determined.
Porosity [rock], английский
The ratio between the volume of pores in a rock and the total volume of the rock, i.e., the capacity of rock to contain a fluid. it is expressed as a percent of rock volume.
Shrinkage, английский
- Contraction
- Decrease in wood dimensions due to loss of water in the wood cell walls. shrinkage across the grain of wood occurs when the moisture content falls below 30 percent, the fiber saturation point. below the fiber saturation point, shrinkage is generally propo
- The reduction in dimension or volume which takes place in timber when the moisture content is reduced below fibre saturation point, expressed as a percentage of the original dimensions or volume. linear shrinkage occurs in three directions radial, tangent
- The settling or reduction in volume of earthen fills, cement slurries, or concrete on setting.
- A synonym for outage.
- In bitmaking by the powder-metal processes, the difference between the dimensions of the finished bit crown and those of the bit mold.

- Укорочение от усадки
- Усадка
- Widthwise or lengthwise contraction of a fiber, yarn, or fabric, usually after wetting a redrying or on exposure to elevated temperature.
- Discrepancy between a firm`s actual inventory and its recorded inventory due to theft, deterioration, loss, or clerical problems.
Shrinkage -, английский
- Допуск на усадку
- Модуль усадки
Shrinkage cavities, английский

Shrinkage cavity, английский
Shrinkage cavity (on radiograph), английский
A small bubble in metal that appears as a dendritic, filamentary, or jagged darkened area on a radiograph film. shrinkage cracks
Shrinkage crack, английский
A crack due to restraint of shrinkage.
Shrinkage crack (bending), английский
Shrinkage cracking, английский
Cracking of a concrete structure or member owing to failure in tension caused by external or internal restraints as reduction in moisture content develops, or as carbonation in the concrete occurs, or both.
Shrinkage cracking., английский
Shrinkage cracks, английский
Shrinkage distortion (of a weldment), английский
Shrinkage force, английский
The force generated by thermoplastic materials when they are subjected to elevated temperatures.
Shrinkage index, английский
Shrinkage is voluminous, английский
