Polyglycols
| Oil glossary |
Polymers of ethylene or propylene oxides used as a synthetic lubricant base. properties include very good hydrolytic stability, high viscosity index (vi), and low volatility. used particularly in water emulsion fluids.

Properties, английский
- A dockable window that displays the properties that are set on the selected object. in most cases, the property values can be edited in the window.
- A ui element that users can click to display information about a selected object.
Volatility, английский
- The degree of price fluctuation for a given asset, rate, or index; usually expressed as a variance or standard deviation.
- A statistical measure of the tendency of a market price or yield to vary over time.
- Волатильность, относительная скорость, с которой цена перемещается вверх и вниз; мера степени изменений рыночной стоимости ценных бумаг, определяемая за период в 52 недели (12 месяцев) и измеряемая в процентах. для того чтобы измерить волатильность, нужно
- This property describes the degree and rate at which a liquid will vaporize under given conditions of temperature and pressure. when liquid stability changes, this property is often reduced in value.
- Относительная скорость, с которой цена перемещается вверх и вниз. вычисляется годовое среднеквадратичное отклонение ежедневного изменения цены.
- Property of having a low boiling point or temperature of sublimation at normal pressure. likewise, having a high vapor pressure at ambient conditions.
- A measure of risk based on the standard deviation of the asset return. volatility is a variable that appears in option pricing formulas, where it denotes the volatility of the underlying asset return from now to the expiration of the option. there are volatility indexes. such as a scale of 1-9; a higher rating means higher risk.
- Нестабильность
- Describes how easily a substance will vaporize (turn into a gas or vapor).
- The property of a liquid that defines its evaporation characteristics. of two liquids, the more volatile will boil at a lower temperature and will evaporate faster when both liquids are at the same temperature. the volatility of petroleum products can be evaluated by tests for flash point, vapor pressure, distillation and evaporation rate.
Particularly, английский
Particular, английский
A частный; конкретный grammar partitioned a разделённый на части sequence 1 одна из базовых операций компьютерной обработки текстов; в каче- стве данных берутся текст либо сегмент текста, грамматика и цель разбора, а на выходе получается удовлетворяющее цели множество значений категориальной отнесённости сегментов в виде, например, дерева разбора. 2 применяется запоминание также и гипотез, выдвигаемых при разбо- ре, и результатов их проверки – м. кэй. 3 используется, в частности, для разбора арифметических выражений. partitioning n членение sentence ~ членение предложений (напр., при переводе )

Polymerization, английский
- The chemical combination of similar-type molecules to form larger molecules.
- A chemical reaction in which the molecules
- A chemical reaction in which the molecular weight of the molecules formed is a multiple of that of the original substances. polymer-modified stucco a stucco containing a small amount of acrylic resin to increase its workability.
- A chemical reaction wherein small molecules combine to form much larger molecules. (also see addition polymerization and condensation polymerization.)
- The chemical reaction in which a monomer combines with itself to form a long-chained molecule called a polymer.
- The chemical combination and recombination of the same unsaturated hydrocarbon with itself to form an extensive chain; the chemical process of combining similar molecules to form larger molecules.
Polyalkylene glycol, английский
Mixtures of condensation polymers of ethylene oxide and water. they are any of a family of colorless liquids with high molecular weight that are soluble in water and in many organic solvents. they are used in detergents and as emulsifiers and plasticizers. pag-based lubricants are used in diverse applications where petroleum oil-based products do not provide the desired performance – and because they are fire-resistant and will not harm workers or the environment.
