The principle of braking is simple: slowing an object by removing kinetic energy from it.

制动原理很简单：通过降低动能使物体减速。

Under normal operation about 60 percent of braking power goes to the front wheels which, because of load transfer under deceleration, take the brunt of the retardation duties.

普遍来说，六成的制动功率分配给前轮，原因前轮是在减速过程中负荷量发生变化，承担降低冲撞力的功能。

The amount of braking power going to the front and rearcircuits can be 'biased' by a control in the cockpit, allowing a driver tostabilise handling or take account of falling fuel load.

驾驶舱内的车手视情况向前面和后面的电路分配不同大小的刹车制动功率，分配方式以使车辆在油量不断减少的情况下稳定行驶为目标。

The Volt also has a regenerative braking system that recovers some of the energy of braking as a charge to the batteries.

This is part of the braking system--a piece of metal put underneath one of the back wheels on extreme slopes.

Actually, the idea of regenerative braking slowing a vehicle down by converting some of its kinetic energy into another form for later use comes originally from locomotive engineering.
