    • Described are methods of depositing a metal film by chemical reaction on a substrate. The method comprises: exposing the substrate to flows of a first reactant gas comprising a group 2 metal and a second reactant gas comprising a halide to form a first layer containing a metal halide on the substrate; exposing the substrate to a third reactant gas comprising an oxidant to form a second layer containing a metal peroxide or metal hydroxide on the substrate during; exposing the substrate to heat or a plasma to convert the metal peroxide or metal hydroxide to metal oxide. The method may be repeated to form the metal oxide film absent any metal carbonate impurity.
    • 描述了通过化学反应将金属膜沉积在基底上的方法。 该方法包括:将衬底暴露于包含第2族金属的第一反应气体和包含卤化物的第二反应气体的流动,以在衬底上形成含有金属卤化物的第一层; 将衬底暴露于包含氧化剂的第三反应气体,以在衬底期间在衬底上形成含有金属过氧化物或金属氢氧化物的第二层; 将基底暴露于加热或等离子体以将金属过氧化物或金属氢氧化物转化为金属氧化物。 可以重复该方法以形成没有金属碳酸盐杂质的金属氧化物膜。

    • A multi-piece projectile for a small arms cartridge includes a metal cup that has a bore, a plastic sheath having a through hole and a high-density core. The cup is a cylindrical metal structure having a bore. The sheath is a cylindrical end and a conical end and a through hole. The core is a cylindrical structure having conical end and a blunt end. The projectile is assembled by placing the core in the through hole of the sheath and then pressing the sheath into the bore of the cup. The assembled projectile is attached to the cartridge by crimping the cup to the orifice in the end of the cartridge casing after it is filled with the propellant. When the projectile is fired all of the components remain coupled together but break apart upon impact with a target. Because the core has a higher mass than the other components the components separate very easily, the majority of the kinetic energy remains in the core. Once separated from the other components, the core is able to penetrate through various protective materials.
    • 用于小武器盒的多件式抛射物包括具有孔的金属杯,具有通孔的塑料护套和高密度芯。 杯是具有孔的圆柱形金属结构。 护套是圆柱形端部,锥形端部和通孔。 芯是具有圆锥形端和平端的圆柱形结构。 通过将芯放置在护套的通孔中,然后将护套压入杯的孔中来组装抛射体。 组装好的抛射体在填充推进剂之后,通过将杯子压紧到盒壳体的端部的孔口而连接到盒体上。 当射弹被射击时,所有的部件保持耦合在一起,但与目标撞击时会分离。 由于核心质量高于其他部件,组件分离非常容易,大部分动能仍然保留在核心中。 一旦与其他部件分离,该芯能够穿透各种保护材料。
