A child hanged to death by a whole night's cold waves Bare, his body has not been Contaminated or filled by dusts Now wholly frozen One night of waiting Is like a century of chaos and loneliness Waiting for the sun to come out And touch him, touch--- Till he slowly and renewedly Turns into water drop by drop Like a candle burned into ashes Inch by inch The stone's aperture Is his end-result Like my hungry and cold childhood Always under mother's eaves Being fed and warmed And now, my heart Like a piece of hailstone Like pieces of hailstone From the hazy sky Falls directly onto the cemented earth 'cause I have no eaves any more

被一夜寒潮吊死的孩子赤裸着尚未被尘埃污染或塞满的身子整个儿已经僵硬那等待中的一夜像混乱而又孤独的一百年就等着太阳出来抚摩他、抚摩——直到他缓缓地一滴滴地重新化成水像蜡烛一寸寸地被烧成灰石头的缝隙是他的归宿像我饥寒的童年总是在母亲的屋檐下被喂养、被温暖而如今，我的心像一颗冰雹像一颗颗冰雹从烟雾弥漫的空中直直地摔到水泥地上因为我已没有屋檐

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。

The methods of computing holdup, pressure drop and temperature drop were simply introduced and some important formulas were derived.

并简要介绍了段塞流工艺计算中的持液率计算及压降和温降的计算，并对重要的公式进行了推导。
