Mr Ewbank says:"A butment BB slides backwards and forward in a stuffing box and is so arranged (by a cam or some other contrivance connected to the axle of the small cylinder on the outside of the case) that it can be pushed into the interior as in the figure, and at the proper time be drawn back to afford passage of the piston" Bramah and Dickenson adopted this configuration in 1790 as steam engine and also a pump.

ewbank先生说："一butment BB心跳幻灯片向后和向前迈进一填料框和是这样安排的（由一个凸轮或其他一些contrivance连接到轴的小圆柱对外面的情况），它可以推进到由于在内部的数字，并在适当时机，订定回负担通过活塞" bramah和狄金森通过此配置在1790年作为蒸汽机，也是泵。

The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis on propulsive performance was examined using three deflexion modes which are respectively, modified Bose mode, cantilever beam with uniformly distributed load and cantilever beam with non-uniformly distributed load.
