查询词典 parallel axis theorem

The precision of a new project for measuring the wheelset geometric parameters is studied once again in this paper. First, the wheelset is fixed and rotated by the device used in vehicle depot as usual. Second, the center line of wheelset axis is determined by a device called axis-center probe. Last, the acting device for sensor can draw a whole felloe profile, which is made up of parallel-pole device and rotating-probe.

Analyzing the relation between earthquake and structure distortion, main fault belt, crust, upper mantle, ground fracture, hotspring, geotherm, conductance frame, stress state in Guanzhong area is analyzed with earthquake mechanism, isoseismal line, crustal stress measure, fault displacement measure, and simulating test results. Earthquake formation mechanism is discussed with dynamics mechanism in Guanzhong base. There are 3 forces and a good medium environment, which are main reasons caused earthquake happened in Guanzhong area. The first force is NE and NEE level extrusion one which is parallel with long axis of Guanzhong base. The second one is level strain which is vertical with long axis of the base.
