This mechanical behavior and seismic characters of the steel cable ladder frames under three-dimension earthquake load and other loads are analyzed by finite element software ANSYS.

[n]Ferrocenophanes are the ferrocene derivatives of intramolecularly bridged, and strained [n]ferrocenophanes are potential monomers for ring-opening polymerization.

The purpose is to feed cooked rice by inequable velocity twin screw feeding machine for single screw extruder, also to solve the problem of "bridge" when it feeds materiel to the single screw extruder.

The construction of the bridge across Taiwan Strait has been studied for a long time andthe feasibility study that has attracted attention among scientists and engineers on both sides of the Taiwan Strait.

Mechanical improvement of the second PVA crusher against bridging accident;

The bridging construction technology at the condition of large longitudinal slope and falling slope

By analysing and researching the function of the feeding system and the structure feature, the method for solving the bridging problem of the feeding funnel is discussed, so as to seek the way for increasing the adaptability between the feeding screw and material based on the summary of various feeding device.
