    摘要： A method of protecting a cementitious mixture from freeze damage is provided. The method consists of incorporating an entrainment air composition into the cementitious mixture to form air voids in the concrete, and further adding an effective agent for nucleating ice, preferably, in the air voids, such that upon the freezing of concrete formed from the cementitious mixture, ice is nucleated in the air voids. In one embodiment, the air entrainment composition includes ceramic shells, which could be impregnated with an agent for nucleating ice such as metaldehyde.

    摘要： A piston structure for a toy gun includes a piston body and a detachable toothed member. The piston body has a chute which is axially disposed on an outer surface of the piston body. The detachable toothed member is made of a metallic material and moveably disposed in the chute. The detachable toothed includes a plurality of teeth which are equally spaced in a lengthwise direction. The piston structure of the present invention provides a longer service life. In case the teeth of the detachable toothed member suffer a lot of wear and tear, the detachable toothed member can be detached from the chute and replaced with a new one to save the cost and to provide an environmental protection effect.

    摘要翻译： 用于玩具枪的活塞结构包括活塞体和可拆卸的有齿构件。 活塞体具有轴向设置在活塞体的外表面上的斜槽。 可拆卸的有齿构件由金属材料制成并且可移动地设置在滑槽中。 可拆卸齿包括沿长度方向等间隔的多个齿。 本发明的活塞结构提供更长的使用寿命。 在可拆卸齿形构件的齿受到大量磨损的情况下，可拆卸的齿形构件可以从滑槽上拆下并更换新的，以节省成本并提供环境保护效果。
