The result, under favorable conditions, is a dynamic equilibrium in which neither fluid volume nor sodium concentration fluctuates too dramatically.

这样在有利的环境下，液体与其中盐浓度之间形成的动态平衡，两者均不致出现大起大落。

The receiver also includes Audyssey MultiEQ room calibration technology, plus that company's Dynamic Volume and Dynamic EQ processing.

ENGADGET: Onkyo TX-NR807 and TX-SR707 receivers keep the updates rolling

Oh yeah, and the company has thrown in dynamic range control -- think Dolby Volume, but you know, more Burmester-like.

ENGADGET: Burmester's 087 surround processor gives ultra-rich a "more affordable" option

Every three years, when the BIS releases its new foreign-exchange market survey, the WSJ Dollar Index will be reweighted using the bank's latest trading volume figures, making it a dynamic index that evolves with the constantly changing market.
