伸缩轴

The program developed with the formula enable the coordinates for points and the parametric formula for curves in the orthographic projection to be transferred into ones in the axonometric projection, which can be directly displayed on the screen. In addition, except for assigned different values to elastic coefficient of the axial direction and the angles of the axes, it is generally adapted in drawing any of the axonometric projections.

用它编程，可以把正投影中点的坐标或曲线的参数方程，转换成屏幕上能够直接显示点的轴测投影的坐标或曲线的轴测投影的参数方程，而且除了赋轴向伸缩系数和轴间角的大小、正负不同的参数值外，对绘任一种轴测投影和相应正投影都具有通用性。

When the axonometry projection plane is parallel to a coordinate axis, and the coefficient of axial deformation of two axes that parallel to the coordinate plane are equal, the cabinet axonometry is produced.

轴测投影面平行于一个坐标轴，且平行于坐标平面的那两个轴的轴向伸缩系数相等的斜轴测投影称为斜二等轴测图。

The PZT plates were polarized in thickness direction. By using the deformation in the plane perpendicular to the direction of polarization, the rotation around Z axis was generated when the torsional vibration around Z axis mode was excited. And the rotation around X axis or Y axis was generated by combining the longitudinal vibration mode and the bending vibtration mode.

The effect of the expansion and the anti-thrust ring on the stress and deformation of the spiral case structure are analyzed respectively. It is found that the presence of expansion reduces in large extent the stiffness of the spiral case as a supporting structure of the turbine. It affects the safe stability of the hydro generator.
