    • A method for verifying scan precision of a laser measurement machine includes the steps of: preparing a standardized BGA model; measuring Z coordinates values of each solder ball peak of the BGA model for certain times; determining a Z coordinates conventional true value of each solder ball peak; measuring X, Y coordinates values of each solder ball centre of the BGA model; determining a coplanarity conventional true value of a seating-plane; determining an optimum scanning mode; determining optimum scanning parameters under the optimum scanning mode; scanning the BGA model under the optimum scanning parameters and the optimum scanning mode; obtaining X, Y, Z coordinates values of each solder ball peak; evaluating the veracity of Z coordinates of each solder ball peak; evaluating the veracity and repetitiveness of coplanarity; and evaluating scan precision of the laser measurement machine.

    • An expandable downhole tool comprises a tubular body having an axial flowbore extending therethrough, at least one moveable arm, and a selectively actuatable sleeve that prevents or allows the at least one moveable arm to translate between a collapsed position and an expanded position. A method of expanding a downhole tool comprises disposing the downhole tool comprising at least one moveable arm within the wellbore, biasing the at least one moveable arm to a collapsed position corresponding to an initial diameter of the downhole tool, flowing a fluid through an axial flowbore extending through the downhole tool while preventing the fluid from communicating with a different flowpath of the downhole tool, allowing the fluid to communicate with the different flowpath by introducing an actuator into the wellbore, and causing the at least one moveable arm to translate to an expanded position corresponding to an expanded diameter of the downhole tool.
    • 可扩展井下工具包括具有延伸穿过其中的轴向流孔的管状体,至少一个可移动臂和可选择性致动的套筒,其防止或允许至少一个可移动臂在折叠位置和膨胀位置之间平移。 膨胀井下工具的方法包括将井下工具设置成在井孔内包括至少一个可移动的臂,将至少一个可动臂偏压到对应于井下工具的初始直径的折叠位置,使流体流过轴流孔 延伸穿过井下工具,同时防止流体与井下工具的不同流路连通,允许流体通过将致动器引入井筒中而与不同的流动路径连通,并且使得至少一个可移动臂平移到膨胀的 对应于井下工具的扩大直径的位置。

    • A two component catalyst activator comprises: 1) a Lewis acidic organoboron (or an orgonoaluminum) component; and 2) a component defined by the formula AOSO2R wherein A is a pseudo cationic group and R is a hydrocarbyl or substituted hydrocarbyl. The catalyst activator is used in combination with a transition metal catalyst for the polymerization of olefins. The catalyst activator provides improved catalyst activities. It is especially useful in solution polymerizations because of desirable solubility characteristics in comparison to the borate salts used in prior activators.
    • 双组分催化剂活化剂包括:1)路易斯酸性有机硼(或羟基铝)组分; 和2)由式AOSO2R定义的组分,其中A是假阳离子基团,R是烃基或取代的烃基。 催化剂活化剂与用于烯烃聚合的过渡金属催化剂组合使用。 催化剂活化剂提供改进的催化剂活性。 与在现有的活化剂中使用的硼酸盐相比,由于具有理想的溶解度特性,因此在溶液聚合中特别有用。
