the cylinder -- 这个圆柱体，圆筒，汽缸, 柱面 ...curved surface -- 曲面 area -- 面积 这个圆柱体的曲面部分的面积。即圆柱体侧面的面积。它等于 圆柱体直径 乘 圆周率 乘 圆柱体的长度。如果 立着放，则是 圆柱体直径 乘 圆周率 乘 圆柱体的高度。
The line joining the two circular bases at the center is the axis of the cylinder. Height (h) as seen in the figure is the perpendicular distance between the two bases. Each base has a radius (r). The measurement of height and radius help us calculate the surface area and volume of ...
The criterion b/D1 = 0.4 allows for larger rotor inlet area (cylinder) than the fan inlet area (circle) to compensate for the separation vortex. This would possibly change in the optimization process for a lower value to bring the ratio of fan inlet area to rotor inlet area closer to ...
These systems represent 2D or one-dimensional vector fields defined on a hollow cylinder that can be determined from one set of projections recorded around a single rotation axis coinciding with the symmetry axis of the tube. Such structures can be fabricated by different synthesis approaches. Tubes...

One end of a long, naturally curved elastic sheet is clamped onto an inclined plane. The other end is acted on by a constant vertical force which tends to open the curved sheet. This nonlinear large deflection problem is studied by series perturbation, numerical integration and exact analytic ...
A type of resonator that may be used in filters is the split ring, consisting of a rectangular plate bent to form a hollow cylinder with a gap running from the top to the bottom of the cylinder at the ends of the bent plate. Thus while the sides of the cylinder or ring will be cu...
