保守路径
尽管如此，普兰提坚信通往权利的最佳途径便是高举保守派旗帜。
And, basically, we say that these properties are equivalent being a gradient field or being path independent or being conservative.根本上说，以下性质是等价的，一个向量场是梯度场，等价于积分与路径无关，也等价于向量场是保守的。
Whenever the work that is done - by a force is independent of its path — it's only determined by the starting point - and the end point — that force is called a "conservative force."不管何时一个力做功，与轨迹无关-，只取决于开始点，和结束点-，这个力被称为，守恒力。
