摘要： The disclosure relates to adjacently mounted circumferentially distributed turbo machine airfoils with a vibration damping system. Each adjacent pair of airfoils includes a fixing and receiving portion, extending between the paired adjacent airfoils, each with a face that are proximal (e.g., in contact with) each other. Vibration can be suppressed by the fixing and receiving portions each having a received magnet fixingly installed therein and a non-magnetic conducting plate therebetween. Each magnet has a pole that faces the pole of the other magnet in between which the non-magnetic conducting plate is located and in which eddy currents can be induced by the relative movement of the magnets due to vibration.

摘要： The invention relates to a method of determining the qualitative composition of soil organic matter (SOM) of mineral soils using thermogravimetry, i.e., by subjecting a soil sample of constant weight to thermogravimetric analysis in the usual way and forming the quotient of the overall weight loss of the sample during heating from 200° C. to 450° C. and the overall weight loss of the sample during heating from 95° C. to 190° C. The method is straightforward and cost-effective, providing reliable figures for all mineral soils, regardless of region, climatic zone, or type of utilization.
