1. What I mean when I say excentric, guess.

2. This paper analyses the influence of excentric shaft connection on force case of drill tool, and discusses the causes of drill tool failure.

3. In this paper influence of geometric excentric ball track of rolling bearing of spindle of machine tool on machining accuracy of workpiece is discussed.

4. By the action of high rotary speed, excentric shaft connection intensifies the fatigue failure of tool.

5. In drill operation , excentric shaft connection has certain inclining prevention function.

6. Based on the non-linear kinematic wave method, a technique using the four point, excentric, implicit, finite-difference numerical scheme to simulate the urban storm sewer system is introduced.
