摘要：【中文】本发明提供了一种除草组合物、除草制剂及其应用，属于除草剂技术领域，所述除草组合物，有效成分包括氟烯草酸和苯唑氟草酮；所述氟烯草酸和苯唑氟草酮的质量比为(1～8):(8～1)。本发明提供的除草组合物以及除草制剂的杀草谱广、对作物安全性高、对抗药性杂草防效高等优点。 【EN】The invention provides a weeding composition, a weeding preparation and application thereof, belonging to the technical field of herbicides, wherein the effective components of the weeding composition comprise flumiclorac-flurtamone and topramezone; the mass ratio of the flumiclorac to the benzoxaflutole is (1-8) to (8-1). The weeding composition and the weeding preparation provided by the invention have the advantages of wide weed control spectrum, high safety to crops, high control effect on drug-resistant weeds and the like.

摘要：【中文】本发明提供了一种楔形的预应力筋用低回缩锚固装置及使用方法,该预应力筋用低回缩锚固装置包括低回缩锚板、夹片、楔形垫板、锚垫板、螺旋筋，所述低回缩锚板与锚垫板之间安装有所述楔形垫板。本发明的有益效果是:本发明尤其是解决了扁形锚具无法实现低回缩张拉的问题。且本发明结构简单、合理，可满足各种强度要求，不仅可以达到桥梁设计的高强度要求，并且通过低回缩锚板与锚垫板之间安装的楔形垫板的斜面配合使用，在二次张拉时，通过推动楔形垫板(补偿间隙)，从而使锚具回缩量有效控制在1mm以内；一次推进到位，操作简单、方便。 【EN】The invention provides a low-retraction anchoring device for a wedge-shaped prestressed tendon and a using method thereof. The invention has the beneficial effect that the problem that the flat anchorage device cannot realize low-retraction tensioning is particularly solved. The invention has simple and reasonable structure, can meet various strength requirements, not only can meet the high strength requirement of bridge design, but also can be used by matching the inclined planes of the wedge-shaped backing plates arranged between the low-retraction anchor plate and the anchor backing plate, and can effectively control the retraction amount of the anchorage device within 1mm by pushing the wedge-shaped backing plates (compensating gaps) during secondary tensioning; one-time pushing in place, simple and convenient operation.
