    • An automated lance system 1 is installed along the annulus of a nuclear power plant steam generator with a tube array of triangular pattern by means of a slidable guide support rail. The guide support rail 2, which is composed of two parallel circular rods 4 separated vertically with a distance, is tightly fixed inside the hand holes. The guide support rail extends from a hand hole at 0 degree to the other hand hole at 90 or 180 degree. The lance body 3 is slideably held on the guide rail by means of supporting circular holders 26 which are attached both on the bottom and on the upper plates of the lance body. The lance body is comprised of a nozzle block 6 with a nozzle cylinder 7 and a first drive means 9 which makes sweeping motion of the nozzle cylinder, a second drive means 12 which aligns the direction of nozzle jets from the nozzle cylinder by rotating the nozzle block in the horizontal plane, and two side support wheels 23 attached to the outer side plate of the lance body, rolling along the inner wall of the steam generator during lancing. For the transportation of the lance, two control cables 27 which extend outward through the hand holes are attached to both ends of the lance body and are driven by a drive means with a drum 28.
    • 自动喷枪系统1通过可滑动的引导支撑轨道沿着具有三角形图案的管阵列的核电站蒸汽发生器的环形空间安装。 引导支撑轨道2由两个垂直分隔开的平行的圆形杆4组成,紧紧地固定在手孔内。 引导支撑轨从0度的手孔延伸到另一个手孔,90度或180度。 喷枪体3通过支撑在支架本体的底部和上板上的圆形保持器26可滑动地保持在导轨上。 喷枪体包括具有喷嘴筒7的喷嘴块6和使喷嘴筒清扫运动的第一驱动装置9,第二驱动装置12通过旋转喷嘴将喷嘴喷嘴的方向对准喷嘴筒 在水平面上嵌装有两个侧支撑轮23,两个侧支撑轮23附接到喷枪体的外侧板,在穿刺期间沿着蒸汽发生器的内壁滚动。 为了运送喷枪,通过手孔向外延伸的两个控制缆索27附接到喷枪本体的两端,并由具有滚筒28的驱动装置驱动。

    • A composite polyamide reverse osmosis membrane. The membrane includes a microporous support and a polyamide layer disposed over the microporous support, the polyamide layer including iodine atoms covalently bonded thereto. The membrane is preferably prepared by a process that includes the steps of providing a microporous support, forming a polyamide layer over the microporous support, and treating the polyamide layer with an aqueous solution comprising a compound, the compound comprising at least one iodine atom. Examples of the compound comprising at least one iodine atom include molecular iodine, iodine monobromide, iodine monochloride and iodine trichloride. The iodine-containing compound may be added to an aqueous solution and dissolved therein or may be formed in situ in the aqueous solution, for example, by adding to the aqueous solution an iodide salt and an oxidizing agent.
    • 复合聚酰胺反渗透膜。 膜包括微孔载体和布置在微孔载体上的聚酰胺层,聚酰胺层包括与其共价键合的碘原子。 膜优选通过包括以下步骤的方法制备,所述方法包括提供微孔载体,在微孔载体上形成聚酰胺层,以及用包含化合物的水溶液(包含至少一个碘原子的化合物)处理聚酰胺层。 包含至少一个碘原子的化合物的实例包括分子碘,一溴化碘,一氯化碘和三氯化碘。 可以将含碘化合物加入到水溶液中并溶解,或者可以在水溶液中原位形成,例如通过向碘化物盐和氧化剂中加入碘化物。
