| 摘 要： | 当逸散时间较长时，用直线回归法采取损失气结果偏低，而逸散时间较短取点数少时，结果偏高。曲线拟合法是比较实用的一种方法，但计算工作量较大。经过模拟实验证明，在变围压条件下，甲烷的解吸规律也服从经验方程Ｑ＝ＷＪ［１－ｅｘｐ（１－ｍ＿１￣ｍ２／ｍ＿２］，并推导出迭代法求取损失量的计算公式。 |
| 关 键 词： | 损失量，直线回归法，曲结拟合法，迭代法 |

| Abstract: | When the lost gas time is long, the gas content estimated by the USBM method is lower than it really is.However if lost gas time is too short and less observations are made,the gas content will be over estimated.The curve fitting method is practical,but the calculating job is complicated.Simuiation tests prove that the rules of methane desorption under the condition of changing surround pressure submit to the experience equation as the following Q=WJ[1-exp(1-m_1￣m2/m_2].And iterative calculating equation of lost gas is inferred. |
| Keywords: | lostgas content USBM curve fitting method interation |
