| Terms for subject Environment (6187 entries) |
| fizikai kémia | physical chemistry (A science dealing with the effects of physical phenomena on chemical properties) | |
| fizikai kezelés | physical treatment (Processes that separate components of a waste stream or change the physical form of the waste without altering the chemical structure of the constituent materials. Physical treatment techniques are often used to separate the materials within the waste stream so that they can be reused or detoxified by chemical or biological treatment or destroyed by high-temperature incineration) | |
| fizikai környezet | physical environment (The material surroundings of a system, process or organism) | |
| fizikai oceanográfia | physical oceanography (The study of the physical aspects of the ocean, the movements of the sea, and the variability of these factors in relationship to the atmosphere and the ocean bottom) | |
| fizikai szennyezés | physical pollution (The introduction or presence of harmful substances or forces in the environment that cause damage to the environment and its processes due to their material actions, as through vibration, thermal alteration or electromagnetic radiation) | |
| fizikai szennyezőanyag | physical pollutant (A pollutant characterized by its influence on environmental conditions caused by forces and operations of physics, such as noise, microwave radiation, vibration, etc.) | |
| fizikai tulajdonság | physical property (Property of a compound that can change without involving a change in chemical composition) | |
| fizikai változás | physical alteration (Any change in a body or substance that does not involve an alteration in its chemical composition) | |
| fizikai-kémiai elemzés | physicochemical analysis (Analysis based on the physical changes associated with chemical reactions) | |
| fizikai-kémiai folyamat | physicochemical process (Processes involving changes in the physical properties and chemical structure of substances) | |
| fizikai-kémiai kezelés | physicochemical treatment (Any processing of wastewater, toxic substances or other materials involving a combination of physical and chemical methods, such as physical processes including air-stripping or filtration and chemical processes including coagulation, chlorination or ozonation) | |
| fizikai-kémiai tisztítás | physicochemical purification (Used to concentrate waste brines and to remove solid organics and ammonia from aqueous solutions. Physical treatment consists of reverse osmosis, dialysis, electrodialysis, evaporation, carbon, adsorption, ammonia stripping, filtration, sedimentation, and flocculation. Chemical treatment consists of ion exchange, neutralization, oxidation, reduction, precipitation, and calcination) | |
| fizikatudomány | physical science (The sciences concerned with nonliving matter, energy, and the physical properties of the universe, such as physics, chemistry, astronomy, and geology) | |
| fiziológia | physiology (The biological study of the functions of living organisms and their parts) | |
| flokkuláció | flocculation (A process of contact and adhesion whereby the particles of a dispersed substance form large clusters or the aggregation of particles in a colloid to form small lumps, which then settle out) | |
| flotáció/úsztatás | flotation (A process used to separate particulate solids by causing one group of particles to float; utilizes differences in surface chemical properties of the particles, some of which are entirely wetted by water, others are not) | |
| fluidágy | fluidised bed (1. A system for burning solid carbonaceous fuel efficiently and at a relatively low temperature, thus minimizing the emission of pollutants. The fuel is crushed to very small particles or a powder and mixed with particles of an inert material. The mixture is fed into a bed through which air is pumped vertically upwards, agitating the particles so they behave like a fluid. The forced circulation of air and the small size and separation of fuel particles ensures efficient burning. 2. A bed of finely divided solid through which air or a gas is blown in a controlled manner so that it behaves as a liquid) | |
| fluidika | fluidics (A control technology that employs fluid dynamic phenomena to perform sensing, control, information, processing, and actuation functions without the use of moving mechanical parts) | |
| fluidizálás | fluidization (A roasting process in which finely divided solids are suspended in a rising current of air (or other fluid), producing a fluidized bed; used in the calcination of various materials, in the coal industry, etc.) | |
| fluor | fluorine (A gaseous or liquid chemical element; a member of the halide family, it is the most electronegative element and the most chemically energetic of the nonmetallic elements; highly toxic, corrosive, and flammable; used in rocket fuels and as a chemical intermediate) |
