crystals

Определение crystals в Английский Язык Английский Язык словарь: This refers to a type of electronic passive component which provides an accurate oscillation frequency with superior temperature characteristics to the circuit It is widely used in cordless telephones, quartz watches as well as other electronic equipment; Crystals are tuned to resonate at an exact frequency so that the transmitter (Tx) and receiver (Rx) operate on the same frequency Crystals may be purchased separately and in many different channels; Crystals are materials which has its molecules arranged in a specific, highly ordered internal pattern This pattern is reflected in the crystal's external structure which typically has symmetrical planar surfaces Many common substances, from salt to sugar, from diamonds to quartz form crystals They can be shaped so that they will vibrate at a specific frequency and are widely used in radio communications and computing devices New Agers believe that crystals posses healing energy See New Age; tartrate crystals can appear in red and white wine Tartaric acid is the principle acid in wine and it gradually precipitates as tartrate crystals as the wine matures Sometimes they can be seen clinging to the bottom of the cork The presence or tartrates is a sign of quality However, most uninformed people object to their presence and modern winemaking practise is to refrigerate white wines to hasten this precipitation so that the bottled wine will remain free of them; Crystals are tuned to resonate at an exact frequency so that the transmitter and receiver operate on the same frequency Crystals may be purchased separately and in many different channels; plural of crystal; Crystal-based technologies such as electronic circuitry, computers, and laser beams, now used in medical diagnostic equipment and surgical techniques, have revolutionized conventional medicine CAT scans, magnetic resonance imaging, mammograms, laser surgery, and microsurgery are commonplace today Newer applications are in development, including Kirlian photography to capture subtle energy emanating from the physical body (the aura), and sonic imagers to graphically display the vibrational tones emitted by the body in illness and health; particular crystals have different energies, if you dream of a particular crystal then check out the crystal page and see what its area of influence is, maybe you need to work with that particular stone; These are considered to have certain healing properties which relieve ailments of the body, mind, and heart For example, quartz crystals, worn on the body, are said by the Health and Fitness Arcade, to enhance the crystalline properties in the body, within the cells, circulatory system, fat tissue, lymph and nervous system; a homogenous solid formed by a repeating three-dimensional pattern of atoms, ions, or molecules and having fixed distances between constituent parts; a mineral, especially a transparent form of quartz - BACK>>; Attractive rock formations of natural or psychological power that should on no account be buried at ancient sites People who advocate this do not know the problems they cause archaeologically and otherwise, and are advocating wilful vandalism on a par to lighting fires, writing graffiti, etc , within a sacred area

Any solid material whose atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Each of a crystal's millions of individual structural units (unit cells) contains all the substance's atoms, molecules, or ions in the same proportions as in its chemical formula (see formula weight). The cells are repeated in all directions to form a geometric pattern, manifested by the number and orientation of external planes (crystal faces). Crystals are classified into seven crystallographic systems based on their symmetry: isometric, trigonal, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic. Crystals are generally formed when a liquid solidifies, a vapour becomes supersaturated (see saturation), or a liquid solution can no longer retain dissolved material, which is then precipitated. Metals, alloys, minerals, and semiconductors are all crystalline, at least microscopically. (A noncrystalline solid is called amorphous.) Under special conditions, a single crystal can grow to a substantial size; examples include gemstones and some artificial crystals. Few crystals are perfect; defects affect the material's electrical behaviour and may weaken or strengthen it. See also liquid crystal.

crystal: In biology refers to large, regular assembly of macromolecules such as proteins and nucleic acids It is possible to isolate and purify proteins or DNA in large quantity and let them crystallize in saturated solution These protein or DNA crystals contain millions of regularly aligned units that allow the determination of the electron distribution from X-ray diffraction studies Since atoms are distinguished by their specific numbers of electrons, their distribution allows an analysis of the atomic composition of proteins or DNA This electron distribution is then used to calculate the so called high resolution structure of molecules
crystal: A crystal is the solid form of a substance in which the atoms or molecules are arranged in a definite, repeating pattern The formation results in one of three ways: a liquid may cool or freeze into a solid; dissolved matter may precipitate out of a solution; or gases may condense into a solid form The external shape of the crystal -- smooth, symmetrically arranged, flat surfaces -- reflects its atomic structure
