By making use of multi-points backward pressure of one dry gas well, this paper introduces how to confirm dynamic friction coefficient of downhole tubing at the exact moment through stable testing material, gives the productivity and the corresponding bottom hole pressure by using productivity equation, calculates wellhead pressure in combination with dynamic friction coefficient of tubing, establishes the correct wellhead outflow performance equation for this well, draws out wellhead outflow performance curve and discusses how wellhead outflow performance equation or wellhead outflow performance curve changes with the decrease of formation pressure or the change of wellhead outflow performance curve.

借助1口干气井的多点回压法试井资料，介绍了如何利用气井稳定试井资料，确定该气井此时此刻井下油管动态摩阻系数；利用产能方程给出产量和对应的井底压力，结合油管动态摩阻系数计算井口压力，建立该井准确的井口流出动态方程并编绘井口流出动态曲线；讨论了随着地层压力递减和井下油管动态摩阻系数变化规律，井口流出动态方程或井口流出动态曲线的变化规律。

With the decrease of soil water potentials, the grain yield decreased, with the transgenic lines decreased less and untransformed WT decreased more.

与WT相比，土壤水势为0kPa时，4个转基因品系的产量高出5.1％—25.9％；土壤水势为-25kPa时，产量高出为9.16％—30.9％；土壤水势为-50kPa时，产量高出12.94％—29.12％。

The steps are: deciding the analogy objects and their parameters to be analogized,breaking out production composition s based on the whole production data during the past years and the production data of individual wells that are put into production in those years,achieving the quantitative forecasting models.

方法一的回归参数为产量构成法求出的参照对象在历年的措施增油量，从而直接预测项目对象在后几年的措施增油量；方法二则通过两个回归参数(产量构成法求出的参照对象历年的总产量和自然产量)间接预测项目对象在后几年的措施增油量。

And most people can not afford to buy a car, let alone the malnte nance of it.

在于我们糊口在成长中国家，汽车出产量不如发家国家那么多。

Artificial selection has yield food crops with higher yield, cows that give more milk, tree that grow faster, and many different types of dogs and cats.
