摘要： A method for manufacturing an at least partially porous, hollow silicon body, including the steps of vertical, anisotropic etching, porosifying, and electropolishing. Hollow silicon bodies manufactured using this method; the body wall including an inner layer, an intermediate layer, and an outer layer, and the porosity of the intermediate layer being greater than those of the inner and outer layers. The use of the hollow silicon bodies.

摘要： The invention relates to an economical pressure measuring device as well as to a favorable method for pressure determination, with which a pressure measurement can be performed from outside the high-pressure container. To that end, the device comprises an ultrasound transmitter mounted outside the pressure container and an ultrasound receiver by means of which transmitter and receiver the transit time of an ultrasonic pulse traveling through the liquid contained in the high-pressure container can be ascertained, and the method comprises generating an ultrasonic pulse outside the high-pressure container measuring the time that the ultrasonic pulse requires to traverse a defined distance calculating the pulse speed of the pulse in the liquid; and from that determining the pressure in the liquid.
