To the problem that the isotropy and the technological efficiency of the parallel kinematic machine based on Stewart platform are not satisfactory, a novel architecture of 6-DOF 3-dimensional platform parallel kinematic machine (6-DOF 3-D PPKM) based on the 2-2-2-SPS 3-D PPR is presented. The technological efficiency of design of the parallel kinematic machine is analyzed. Its workspace and the effect of design parameters to the workspace volume are studied. By using the submatrices of Jacobian matrix and force Jacobian matrix, the kinematics/mechanics transmission isotropic indices, kinematics transmission indices, load-bearing capacity indices at any configuration of the parallel kinematic machine are proposed, respectively.

The electrostatically actuated membrane is used in this kind of tunable capacitor. Both of two parallel-plate of the new tunable capacitor can deflect when subject to parallel-plate electrostatic actuation, this is different with the novel parallel-plate tunable capacitor which is only one of the two parallel-plate can deflect.

这种可调电容器采用静电驱动金属膜的原理工作，与一般的只有单极板可动的可调电容器相比，这种结构的不同之处在于采用一些复杂的制作工艺，制作出电容两块极板均可动的可调电容器。

Circular and catenary always represent the shapes of minor principal stress soil arch between two parallel walls, but which shape should be used in the calculation of active earth pressure on two parallel walls remains disputed. Considering fully developed wall friction or partially developed wall friction, circular and catenary, the two shapes of minor principal stress soil arch between two parallel walls are theoretically analyzed. According to the shapes of soil arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are obtained, and the formula of active earth pressure on two parallel walls is derived.
