The invention belongs to the technical field of ballastless track interface mechanics, and particularly discloses an assembly type test device and test method for measuring normal mechanical parameters of an interlayer interface of a ballastless track. The center of the measuring platform is provided with a left side fixing device and a right side fixing device which are used for fixing the pushing test piece, the pushing test piece comprises an upper concrete test piece and a lower concrete test piece, the lower concrete test piece is provided with a reserved fixing hole for fixing the pushing test piece, and the reserved fixing hole is rigidly matched with a positioning screw rod, so that the pushing test piece can be fixed. The self-alignment assembly is realized; a simple and reliable measurement and calculation method is developed in a matched mode and used for obtaining a normal force-displacement relation curve and key normal cohesion parameters of the ballastless track interlayer interface, and a theoretical basis and data support are provided for numerical simulation and damage analysis of ballastless track interlayer interface behaviors.

The invention relates to a method for determining the additive content (vol-% or wt-%) in a tobacco paper for an electronic cigarette, which is produced from a pulp-like mass of additives, water, aroma substances and tobacco, wherein the pulp-like mass is dried into a single-layered tobacco paper, wherein the tobacco paper is measured in at least one microwave resonator, which has two resonance modes with two resonance frequencies, the smaller of the two resonance frequencies being in a frequency range of less than 1 GHz and the larger of the two resonance frequencies being in a microwave range of more than 2 GHz, for each of the two resonance modes a density-independent moisture value is calculated and from the two density-independent moisture values the additive content is determined.
