    • Methods of reducing the permeability of a subterranean formation to aqueous-based fluids using a water-soluble relative permeability modifier that comprises a hydrophobically modified polymer, wherein the hydrophobically modified polymer is a reaction product of: a hydrophilic polymer that comprises a polymer selected from the group consisting of a polyvinylamine, a poly(vinylamine/vinyl alcohol), and an alkyl acrylate polymer; and, a hydrophobic compound comprising at least one alkyl chain having a carbon chain length between about 4 and about 22 carbons. The water-soluble relative permeability modifier may be placed within a subterranean drilling operation such that the water-soluble relative permeability modifier attaches onto surfaces within the subterranean formation to effect permeability of aqueous fluids.
    • 使用包含疏水改性聚合物的水溶性相对渗透性改性剂降低地层对水基流体的渗透性的方法,其中所述疏水改性的聚合物是以下物质的反应产物:亲水性聚合物,其包含选自 由聚乙烯胺,聚(乙烯胺/乙烯醇)和丙烯酸烷基酯聚合物组成的组; 以及包含至少一个碳链长度在约4至约22个碳之间的烷基链的疏水化合物。 水溶性相对渗透性改性剂可以放置在地下钻井操作中,使得水溶性相对渗透性改性剂附着在地层内的表面上以实现含水流体的渗透性。

    • A cinema structure (1) comprises an auditorium (3) having a flat planar screen (10) onto which images of a motion picture is projected by a projector (12) located adjacent a rear wall (5) of the auditorium (3). Seating (14) comprising rows (15) of seats (16) are supported on tiered plinths (18) which are tiered at an angle α of approximately 25°. A front row (15a) of the seats (16) is formed in two parts, namely, a left-hand part (44a) and a right-hand part (44b) on a front plinth (18a), which is also formed in two parts, namely, a left-hand part (42a) and a right-hand part (42b). The left and right-hand parts of the front row (15a) and the front plinth (18) define central gaps (45,43, respectively) in order to accommodate the projected beam of the motion picture uninterrupted from the projector (12) to the screen (10). The rows (15) of seats (16) are pitched at a horizontal pitch (P1) of 1,300 mm, and each plinth (18) is at a vertical height (h1) of approximately 600 mm above its adjacent plinth (18). The front plinth (18a) is at a height of approximately 1,200 mm above a floor (8) of the auditorium (3). The screen (10) extends substantially the width of a front end wall (4) between opposite side walls (6) of the auditorium (3), and extends substantially the full height of the front end wall (4) between the floor (8) and the ceiling (9) of the auditorium (3).
    • 电影院结构(1)包括具有平面平面屏幕(10)的礼堂(3),运动图像的图像通过位于礼堂(3)的后壁(5)附近的投影仪(12)投影到其上。 包括座位(16)的排(15)的座位(14)被支撑在分层的底座(18)上,分层的角度α约为25°。 座(16)的前排(15a)形成在前底座(18a)上的左侧部分(44a)和右侧部分(44b)两部分中,该左侧部分(44a)和右侧部分(44b)也形成在 两部分,即左手部分(42a)和右手部分(42b)。 前排(15a)和前底座(18)的左右部分分别形成中心间隙(45,43),以便将投影机(12)不间断的运动图像的投影光束适应到 屏幕(10)。 座(16)的排(15)以1,300mm的水平间距(P1)倾斜,并且每个底座(18)处于其相邻底座(18)上方大约600mm的垂直高度(h1)。 前底座(18a)在礼堂(3)的地板(8)上方大约1200mm的高度。 屏幕(10)基本上延伸在礼堂(3)的相对侧壁(6)之间的前端壁(4)的宽度,并且基本上延伸到前壁(4)的底板(8)的整个高度 )和礼堂上限(9)(3)。
