    • A method for the detection of a specific material in an object (1), especially in a piece of luggage, using electromagnetic beams, whereby the intensities of non-absorbed beams from at least three beam planes (5.1–5.2) in corresponding detector arrays (4.1–4.5) are measured and evaluated, using the following steps according to the invention:1. generating an at least two-dimensional picture of the object (1) from the measured intensity values;2. selecting one of the spatial regions displayed in the picture as a basis of the value of a material value, which is determined from intensity measurements, for examination;3. determining at least one spatial-geometric value in the region to the examined from positional data of a two-dimensional picture and from intensity values using a stored value of a specific, absorption-influenced value of a suspected material.4. determining, in addition, the corresponding spatial-geometric value solely from three-dimensional geometric values, which are determined from measured intensity values; and5. comparing, directly or indirectly, values of the spatial-geometric values determined in steps 3 and 4, or values derived therefrom, in order to determine if the suspected material is actually present.
    • 一种用于使用电磁束检测物体(1)中特定材料(特别是一件行李)中的特定材料的方法,由此在相应的检测器阵列中来自至少三个光束平面(5.1-5.2)的未吸收光束的强度 (4.1-4.5),根据本发明使用以下步骤进行测量和评估:1.从测量的强度值生成对象(1)的至少二维图像; 2.选择图像中显示的空间区域中的一个作为从强度测量确定的材料值的值的基础进行检查; 3.使用可疑材料的特定吸收影响值的存储值,从二维图像的位置数据和强度值确定区域中至少一个空间几何值。 另外确定相应的空间几何值,仅由三维几何值,其由测量的强度值确定; 以及5.直接或间接地比较步骤3和4中确定的空间 - 几何值的值或由其导出的值,以便确定疑似材料是否实际存在。

    • The invention relates to metal foam bodies having an open-porous structure as well as a method for producing thereof wherein according to the set task such metal foam bodies are to be provided which achieve an increased oxidation resistance and/or an increased corrosion resistance. With the metal foam bodies having an open-porous structure according to the invention, for such metal foam bodies within the webs of the open-porous structure there are channel shaped cavities formed as being determined by the production. At the same time, the webs and cavities will be provided with a metallic protective layer made of a material differing from the metallic starting material of the foam body or the channel shaped cavities will be filled with this material. For this, an adequate metal powder or an alloy component being included in the powder will be used which becomes liquid and forms a liquid phase respectively during thermal treatment below a temperature at which the metal of the base foam body is melting. Due to the capillary action wetting the surfaces of channel shaped cavities within the webs can be achieved such that after cooling down a metallic protective layer is forming or the channel shaped cavities are filled.
    • 本发明涉及具有开孔结构的金属泡沫体及其制造方法,其中根据设定的任务,将提供这样的金属泡沫体,其实现增加的抗氧化性和/或增加的耐腐蚀性。 对于根据本发明的具有开孔结构的金属泡沫体,对于在开孔结构的腹板内的这种金属泡沫体,存在通过生产确定的通道形空腔。 同时,纤维网和空腔将设置有由与泡沫体的金属起始材料不同的材料制成的金属保护层,或者通道形状的空腔将被该材料填充。 为此,将使用在粉末中包含的足够的金属粉末或合金成分,它们在基体泡沫体的金属熔化的温度以下的热处理期间分别成为液体并形成液相。 由于毛细作用润湿,纤维网内的通道形状空腔的表面可以实现,使得在冷却之后,形成金属保护层或填充通道形状的空腔。
