因此，尽管事实上没有变动齿轮，使用可调节滑杆调节扭矩以提供加速和减速时的震动，就像有个真实的变速箱似的。

So, even though no actual gears are being changed, using the paddle-shift modulates the torque to provide the jolts of acceleration and deceleration that would happen if there were a real gearbox.

各种的齿轮和枢纽都是必须的；有了它们，才可以使你的机器活动。

Many separate wheels and joints are required to make the piece of machinery.

但是要感谢更轻的齿轮和由很轻的材料制作的结构，像碳纤维，最新的型号重量接近1磅的发电机有希望在明年或者某些时候上市。

But thanks to lighter gears and a framework made of lightweight materials such as carbon fiber, the latest model, which is expected in the next year or so, should weigh closer to one pound.
