针对长庆低渗透气藏进行修正等时试井过程中出现试采瞬时测试产量大于绝对无阻流量的异常现象，在明确气井瞬时测试产量与其绝对无阻流量概念的基础上，通过对气井绝对无阻流量获得过程及气井绝对无阻流量计算结果影响因素的分析，在理论上证实了气井瞬时测试产量大于其绝对无阻流量的可能性，从而解释了现场测试过程中出现的特殊现象。

Using augmented Dickey-Fuller test, the result shows that BDI logarithm series is nonstationary but the first difference is stationary, i. e. it is integrated of order one. High-level ARCH effect was certification in the BDI logarithm series by ARCH LM test, and GARCH (1, 1) model was used to eliminate the conditional heteroscedasticity. Through variance ratio test, the result shows, that the random walk hypothesis of BDI logarithm series can be rejected and international dry bulk shipping market is inefficient.

运用ADF检验方法对BDI的对数序列进行平稳性和单整检验，结果证明BDI对数序列是一个非平稳过程，经一阶差分后是平稳过程，即BDI对数序列是一阶单整过程；通过ARCH LM检验认为BDI对数序列存在高阶ARCH效应，并用GARCH(1，1)模型消除了残差序列的条件异方差性；通过方差比检验法对国际干散货航运市场的收益率序列进行了检验，结果显示BDI的对数序列的随机游走假设被拒绝，国际干散货航运市场不是一个有效的市场。

Methods 80 cases were divided into control group and test group with 40 cases respectively. Epidural catheter was left in test group, connected with "Tuoren" patient-controlled epidural analgetic pump with dicaine 100 mg+morphine 10～15 mg+droperidol 5 mg,which were dissolved into NS to 100 ml. LCP model was as follows:morphine 2～3 mg, background dosage: 2 ml/h, PCA 0.5 ml each time; The control group injected morphine 3 mg through epidural conduit each time to relieve spasm and pain according to the symptoms to observe and record the effects and side effects. Results Test group:39 cases were with remarkable effect, 1 cases was common.
