“operator”的概念、定义、翻译、参考文献-科学参考

operator

Physics

A mathematical symbol indicating that a specified operation should be carried out. For example, the operator √ in √x indicates that the square root of x should be taken; the operator d/dx in dy/dx indicates that y should be differentiated with respect to x, etc.

Mathematics

A term variously used in mathematics and which is typically synonymous with function. The terms ‘linear operator’ and ‘differential operator’ are common, where the elements of the domain are themselves functions.

Chemistry

A mathematical entity that performs a specific operation on a function to transform the function into another function. For example, the square root sign √ and the differentiation symbol d/dx are operators.

Chemical Engineering

1. A trained person who has responsibility for carrying out the day-to-day operation of a process or plant.

2. An industrial company that is a member of a joint venture and appointed to carry out all the activities and operations for a particular process plant, or for activities such as exploration and drilling for oil.

3. A mathematical entity used to perform a specific operation such as ∫ (the integral operator) or Δ (the differential operator).

Computer

1. A person responsible for the immediate supervision of the hardware of a computer system.
2. A function that can be applied to one or more operands so as to yield a result. It is (usually) a symbol representing an operation to be carried out, as opposed to a variable, which represents a data value. See also arithmetic operator, logic operation, relational operator, precedence.

Philosophy

A term that signifies an operation. An operation is a function, so operators include expressions like ‘square root’ or ‘&’. The quantifiers are also known as operators, as are expressions like (ix)…, or (µx)…, taking us from a predicate Fx to the only thing that is F, or the least thing that is F, respectively.
