摘要： Disclosed is a method for controlling power supplied to an electric drive system of an electric bicycle. The method includes determining a pedal assist power level for the electric drive system, determining a first current to be applied to the electric drive system based on the pedal assist power level, detecting a user selected boost assist at a first input while the first current is being applied to the electric drive system, and determining a second current to be applied to the electric drive system based at least in part on both the user selected boost assist and a boost trigger, the boost trigger being received via a second input.

摘要： Lenses of DNAPL suspended on clay strata in a sandy aquifer are treated with potassium permanganate. The solution is injected out into the aquifer from a port, and forms a horizontal disc of treatment liquid. The (heavy) liquid then gradually percolates down onto the DNAPL lens.
