In order to further the investigate influence of a secondary lateral stopping block on the dynamic performance of a vehicle and to supply a reference and guidance for bogie design,the effects of parameters of a stopping block,including stop gap and stop stiffness,on comfort and safety indices of running were probed into by taking the curve negotiation of vehicle as an example.

This paper reviews for and comments on the current advance of overseas research on neotectonics in terms of four aspects: interaction between tectonics, surface erosion processes, and climate in orogens, interaction between rift segments in continental rift zones, transverse drainages, and planation surfaces.
