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。

Results show that the zonal method combined with the conjugate gradient method can solve the equivalent gray absorption coefficient well in the non-gray gases system.
数值模拟结果表明，段法与共轭梯度法结合可以较好地反演非灰系统的当量灰吸收系数。
