Advanced ,-Theory: Supplementary Sections,The previous chapter treated the main concepts of the .-theory of the parametric excitation of waves in terms of spatially homogeneous pumping. Yet, a variety of interesting situations has not been treated.Vital-Signs 发表于 2025-3-27 05:12:35

Stationary Nonlinear Behavior of Parametrically Excited Waves. Basic ,-Theory,ted waves) results in a great number of waves simultaneously excited and intensively interacting. The state of the waves is determined mostly by some particular factors: the dispersion law of the waves and the nonlinear and dissipative properties of the medium. These factors can vary considerably in different cases.Prologue 发表于 2025-3-28 12:40:35
r Schwangere und Ungeborenes.Praxisorientierte Handlungsempf.Bis zu 25% aller Schwangerschaften gelten heutzutage als Risikoschwangerschaft. Deshalb sind bei Frauen mit speziellen Grunderkrankungen wie z.B. bei Diabetes mellitus, früheren Fehlgeburten, Herzerkrankungen schon bei der Planung und spät
