Sometimes, owing to the limitation of specimens or testing conditions, etc., the measurement for the exact travel time of a wave phase is very difficult.

有时，由于样品和试验条件等方面的限制，准确测定波动的走时很困难。

It's going to be positive in terms of its wave function or in terms of its phase anywhere where y is positive.

只要ｙ大于零它的波函数,或者说是相位为正。

That's not a positive and negative charge, that's actually a phase, and that arises from the wave equation.

这不是指正负电荷，它是指相位，这是从波函数中得来的。

Functional-imaging studies of the brain have revealed another tantalizing clue: During the aura phase, a wave of electrical activity sweeps over the outer, furrowed layer of the brain known as the cortex, at a pace of 2 to 3 millimeters per minute.

They discovered that by shifting the "phase" of light so that the peaks of one wave line up with the valleys of an adjacent one, the two cancel each other, creating "shadows" between waves that are smaller than the waves themselves(see diagram, p. 141).
