“lag”的概念、定义、翻译、参考文献-科学参考

lag

Physics

See phase angle.

Mathematics

The time difference between the pairs of observations used in calculating the autocorrelation of a sequence. For a monthly time series the important lags are likely to be 1 (the most recent performance), 3, 6, and 12, reflecting the performance at corresponding points in the business cycle.

Statistics

See autocorrelation.

Internet

A period of time during which nothing happens; for example, the time that it takes for a file to be downloaded. It is also called a hang.

Electronics and Electrical Engineering

1. The amount, measured as a time interval or a proportion of the a.c. cycle, by which one periodically varying wave is delayed in phase with respect to the similar phase in another wave. Compare lead¹.
2. The time interval between the transmission of a signal and its detection by a receiver.
3. The delay between a correcting signal of a control system and the response to it.
4. The persistence of the electrical image in a television camera tube; it may be several frames in duration.

Geology and Earth Sciences

A normal, dip-slip fault, dipping less than 45°, on which there has been a relative downward displacement of the hanging wall. See also fault.
