    摘要: The invention relates to modified SiO.sub.2 gels (xerogels), the preparation thereof and the use thereof as thermal insulators. The xerogels are prepared by acidifying an aqueous waterglass solution, polycondensing the silicic acid produced thereby, by adding a base, to an SiO.sub.2 gel, removing the water from the resulting gel by extractive distillation with an organic solvent which forms with water an azeotrope which separates on cooling into two phases, reacting the gel with a silylating agent, and then drying at pressures and temperatures which are below the critical pressure and/or the critical temperature of the organic solvent used for removing the water.

    摘要: The invention relates to a method of determining a replacement distance when taking aim on a target (2) with a target distance D (6) and an elevation angle α (5) between a line of sight (4) to the target (2) and a horizontal plane (3) with a weapon (9) in order to fire projectiles with an approximately flat trajectory. The replacement distance is determined from the target distance D (6) by means of a correction function, and the correction function is determined exclusively from non-ballistic characteristic values and at least as a function of the target distance D (6) and the difference in angle between the elevation angle α (5) and the shooting angle.
