“dynamic”的概念、定义、翻译、参考文献-科学参考

dynamic

Computer

Capable of changing or of being changed. With reference to operating systems, the implication is that the system is capable of changing while it continues to run. As an example, the total amount of memory available may be defined by the contents of a word within the operating system. If this word can be altered without stopping the system and reloading a fresh copy of the operating system, then it is possible to alter dynamically the total amount of memory on the system.
With reference to programming, the adjective is applied to operations that take place while a program is running, as compared with those that take place during the compilation phase. For example, dynamic arrays are allocated space while the program is running.
Compare static.

Electronics and Electrical Engineering

Denoting any electrical device, circuit, or apparatus in which the electrical parameters are constantly changing. The term can be applied to those devices that operate with alternating currents and voltages, especially those with a marked frequency dependence. It is also used to describe components, such as varactors, in which an electrical property varies with the operating conditions, e.g. if the reactance is a function of the applied voltage. Any device or circuit in which the signals decay over a period of time unless regenerated, is also termed dynamic. Dynamic memory is an example of this type of device. Any component, circuit, or device that is not dynamic or that is operated with essentially constant electrical conditions is described as static.
