与解析方法的对比表明，本文的扰动边界元方法计算精度很高，适用于任意形状非均质油藏的不稳定压力动态分析。
Lastly, the perturbation boundary element method is verified against the analytical solution and is applicable to transient pressure analysis of arbitrarily shaped reservoirs.
除了明显的泵问题(例如确保泵在设定压力下输送水)之外，其它问题也会影响工件精度。
Except for the obvious pump problems (such as make sure that the pump can feed water under the setting pressure); other problems also will affect the work piece precision.
