    摘要： The invention relates to a higher-strength steel strip or steel sheet comprising a predominantly ferritic-martensitic microstructure with a martensite content of between 4 and 20%, wherein the steel strip or steel sheet, apart from Fe and impurities due to smelting, comprises (in % by weight) 0.05-0.2% C, ≦1.0% Si, 0.8-2.0% Mn, ≦0.1% P, ≦0.015% S, 0.02-0.4% Al, ≦0.005% N, 0.25-1.0% Cr, 0.002-0.01% B. Preferably the martensite content is approximately 5% to 20% of the predominantly martensitic-ferritic microstructure. Such a higher-strength steel strip or steel sheet made from a dual phase steel comprises good mechanical/technological properties even after being subjected to an annealing process which includes an overageing treatment. Furthermore, the invention relates to a method for producing steel strip or steel sheet according to the invention.

    摘要： A capacitive measuring device with a measuring electrode (3) arranged some distance from a counter-electrode (8), a dielectric material for analysis is arranged between the electrodes (3, 8), and a measuring current (IC) is supplied to the measuring electrode (3) and the capacitance-dependent capacitor voltage (UC) is measured and evaluated. The measuring electrode (3) is surrounded by a plurality of guard ring and/or auxiliary electrodes (13, 6N, 6NA) spaced apart therefrom in a staggered arrangement and at least partly covering the side walls (18), and each of which is constantly being corrected via a potential-controlling circuit (17) to the potential of the measuring electrode (3), so as to thereby largely eliminates leakage currents to the guard electrodes (13, 6N, 6NA), in the region of the measurement zone the side wall (18) being virtually completely covered with additional guard electrodes (61-6N; 61A-6NA), divided in a ribbon shape parallel to the measuring electrode (3) or divided in a two-dimensional grid, and each of the guard electrodes is wired to its potential-controlling circuit (17) in a manner that minimizes any flow of current into the guard electrodes (61-6N; 61A-6NA).
