On the basis of the material balance equation, this paper develops a method to predict the formation pressure using cumulative production data for normal pressure confined gas reservoir.
以正常压力系统封闭气藏的物质平衡方程序为基础，建立一种利用累积产气量计算气藏地层压力的方法。

The current general electronic balance also has peeled (net) weighing, cumulative weighing, piece weighing functions.
目前一般电子天平还具有去皮(净重)称量、累加称量、计件称量等功能。

Mr. WEHSER also introduces that in order to balance IPR and standards, FRAND is normally used, but FRAND is far from perfect and cumulative royalty can be high.
