    • The invention relates to a method for producing the thin film made of lead zirconate titanate in a 111-oriented perovskite structure, comprising the following steps: providing a substrate having a substrate temperature above 450° C. and a lead target, a zirconium target, and a titanium target; applying the thin film by sputtering lead, zirconium, and titanium from the respective targets onto the substrate, wherein the total deposition rate of lead, zirconium, and titanium is greater than 10 nm/min, the deposition rate of zirconium is selected in such a way that the atomic concentration of zirconium with respect to the atomic concentration of zirconium together with titanium in the thin film is between 0.2 and 0.3, and the deposition rate of lead is selected to be sufficiently low, depending on the substrate temperature and the total deposition rate of lead, zirconium, and titanium, for an X-ray diffractometer graph of the 111-oriented lead zirconate titanate to have a significant peak value (19) in a diffraction angle range from 33 to 35.5°; and completing the thin film.
    • 本发明涉及一种在111取向的钙钛矿结构中制造由锆钛酸铅制成的薄膜的方法,包括以下步骤:提供基片温度高于450℃的基片和引线靶,锆靶, 和钛靶; 通过将铅,锆和钛从各个靶溅射到衬底上来施加薄膜,其中铅,锆和钛的总沉积速率大于10nm / min,锆的沉积速率选择在 锆的原子浓度相对于锆的原子浓度与钛一起在薄膜中的原子浓度在0.2和0.3之间的方式,并且根据衬底温度和总沉积选择铅的沉积速率足够低 对于111取向铅锆钛酸铅的X射线衍射仪图,在33〜35.5°的衍射角范围内具有显着的峰值(19)的铅,锆和钛的比率; 并完成薄膜。

    • A streaming database management system may provide support for creating a new continuous query operator for on-the-fly addition of a new query, e.g., a new SQL query and/or new continuous query operator, into a shared continuous query plan. Alternatively, the streaming database management system may associate the new query on-the-fly with an existing continuous query operator, such as a relational operator and expression evaluator, to reuse the existing continuous query operator. In some embodiments, multiple operators are grouped for on-the-fly addition to the shared continuous query plan. Alternatively, the streaming database management system may identify a group of multiple operators in the shared continuous query plan for reuse by the new query.
    • 流数据库管理系统可以为创建新的连续查询运算符提供支持,以便将新查询(例如,新的SQL查询和/或新的连续查询运算符)新增到共享的连续查询计划中。 或者,流数据库管理系统可以将新查询与现有的连续查询运算符(例如关系运算符和表达式求值器)进行即时关联,以重用现有的连续查询运算符。 在一些实施例中,多个运算符被分组以用于共享连续查询计划的即时添加。 或者,流数据库管理系统可以在共享连续查询计划中识别一组多个运算符,以供新查询重新使用。
