| 释义 | vector noun[ C ] specializeduk /ˈvek.tər/ us /ˈvek.tɚ/ vectornoun[C] (QUANTITY)mathematics, physics (alsovector quantity) a quantity that has both size and direction: We use vectors to, for example, describe the velocity of moving objects. In graphical representation, a vector is drawn as an arrow, with the arrow having both a magnitude (how long it is) and a direction (the direction in which it points). Momentum is a vector quantity but inertia is not. Compare scalar In navigation the vectors representing each ship's course and speed are plotted, to determine if the ships are likely to collide. Vector quantities include velocity and direction. He used arrowed lines to represent each vector quantity. Physics: energy, force & power animal magnetism anti-gravity attract attraction ballistic entropic entropically equilibrant erg excited geothermal inertia jet propulsion preatomic propulsive radiant energy self-propulsion sine curve the sound barrier thermodynamics vectornoun[C] (OF DISEASE)biology an insect or animal that carries a disease from one animal or plant to another: （在动物或植物之间传播疾病的）昆虫媒介，传病媒介 vector ofMosquitoes are the vectors of malaria.蚊子是疟疾的传播媒介。 Passing on illness & causing disease aerosolize avirulent communicability community transmission contact tracer contagion contagious epidemic fester infect infestation interepidemic interpandemic mediastinum non-communicable skin to skinidiom spreader super-spreader transferable transmissibility vector adjective[ before noun ] specializeduk /ˈvek.tər/ us /ˈvek.tɚ/ computing A vector image is one that can be made into any size without its quality being affected: You can export a map either as a bitmap or as a vector file. Vector images can be enlarged or shrunk. The image is editable as long as it remains in a vector format. Compare If you are using a stock vector image, it is probably also being used by someone somewhere else in the world. The software converted both text and graphics into vector files, when instructed to do so. Graphics files that are saved in vector formats are stored as points, lines, and mathematical formulae describing the shapes that make up a drawing. Computer concepts 2FA 2SV 3-D printing adaptive learning additive manufacturing haptics HCI hex hexadecimal hill climbing infection stack tebibyte telematic telematics telerobotics teraflop texture wan word processing vector | American Dictionaryvector noun[ C ] us/ˈvek·tər/ physics a representation of something that has both direction and size, usually an arrow whose direction represents direction and length represents size vector quantityphysics A vector quantity is something that can be represented by a vector. Examples of vectorvector If it is to take the eye with it, the line becomes a series of vectors. Obvious potential concerns are the immune and inflammatory responses to viral vectors. We hypothesized that such viral vectors, immobilized on a solid surface, could infect cells only at the contact site between the solid surface and cells. They construct upon that set of states the results of observations that may be represented as vectors in a suitable space. The main vectors of introduction were, in decreasing order, host plants (accounting for nearly half of the introductions), stored products and wood material. The mean vectors were then calculated for each of the nine releases, that is, with pooled recapture data from the first and second recapture period. Scientists would like to suppress the ability of insects to serve as vectors of human and animal pathogens. In some areas, multiple malaria vectors occur sympatrically. Probability models to facilitate declaration of pest-free status that are vectors of disease. The articles in this volume represent an introduction to those systems, their vectors, actors and structures. What is the probability that these vectors do not form a d-simplex? Each of the following ten row vectors represents a facet of our polytope. However, this basis may be quite large, or may contain vectors with large components. Birds are obviously seed-dispersal vectors, but the multi-seeded infructescences frequently entangle birds, often fatally. Obviously for r2 close to 1, the two vectors will be highly correlated, and y will be small. See all examples of vector These examples are from corpora and from sources on the web.
