The key findings specify the informal closure strategies used by the high-status group in relation to the low-status group.

The study shows that the pressure transient curve of fractured wells in closed circular formation can be divided into six different flow regimes. In condition of the same fracture opening width and fracture length, compared to rectangular fracture, the pressure drop with tapered fracture is bigger, and the dimensionless pressure and pressure derivative curves are higher. In condition of the same fracture opening permeability, compared to linear declining and constant conductivity fractures, the pressure drop with exponential declining conductivity fracture is the biggest, and the dimensionless pressure and pressure derivative curves are the highest.

研究结果表明：圆形封闭地层压裂井的压力动态曲线可以划分为6个流动阶段；在相同裂缝开口宽度和相同裂缝长度的条件下，与矩形裂缝相比，楔形裂缝压力消耗大，表现为无因次压力及压力导数曲线越高；在相同裂缝开口渗透率的条件下，与导流能力呈线性降低的裂缝以及常导流能力裂缝相比，导流能力呈幂指数降低的裂缝压力消耗最大，表现为无因次压力及压力导数曲线最高。

As mathematicians say,"Every simply connected closed 3-manifold is homeomorphic to a 3-sphere."

用数学语言表达就是"每个单连通3重（3-manifold）封闭体与一个三维球体同胚。"

The sticker rivals that of the Bugatti Veyron, but there's one twist: Maserati has no plans to homologate the MC12 Corsa for road use or motorsports.
