Oxyhydrogen isotope relationship curve in the region indicates that the samples basically distribute in the upper left of local rainwater line and an obvious phenomenon of reverse "Oxygen drifting" exists. This kind of isotope distribution is the only one in the most karst groundwater in northern karat spring area that the authors have ever studied.

Upon to Ljapunov's concept of motion stability, the dynamic instability should be understood as the existence of at least one perturbed motion, which is initially in the small neighbourhood of the undisturbed motion and which starts at t =t〓, when is singular for the first time, depart monotonically from the neighbourhood, this phenomenon is proposed to be referred to as the quasi-bifurcation phenomenon.

According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.
