    摘要: A dielectric element for positioning on an examination subject for locally influencing the B1 field distribution during magnetic resonance data acquisition contains a relaxation agent bound to mutually separated particles. The relaxation agent incorporates a paramagnetic substance. In a corresponding method for acquiring magnetic resonance data from an examination subject, such a dielectric element is positioned on the examination subject for locally influencing the B1 field distribution, by homogenizing the B1 field of a magnetic resonance apparatus.

    摘要: Prepregs can be prepared by impregnating reinforcement materials such as glass, carbon or plastic (in the form of fibers or nonwoven or woven materials) with a solution of a polyepoxy resin and a polyamine as a hardener and subsequent drying. For the manufacture of storage-stable prepregs based on polyepoxy resins, 1,3,5-tris(3-amino-4-alkylphenyl-2,4,6-trioxo-hexahydrotriazine with a C.sub.1 - to C.sub.4 alkyl radical is used as the hardener. The new method leads to storage-stable prepregs and assures that composite materials, especially circuit boards, manufactured therefrom meet the requirements for these materials.
