The oscillatory phase of the electromagnetic wave doesn't even advance such as in a vacuum — this is what we term a zero-phase delay.
电磁波的震荡甚至不像在真空中那样前进了。 这就是我们称之为零相位表现。

Since this example application doesn't have validators associated with the components (I'll introduce this feature in the next article), you'll simply advance to the update model values phase.
