以...为中心旋转

Moreover, we used the rotation tripod to locate the lens at the center of rotation in order to avoid the dead angle at the center of the rotation position.

而且，使用了以镜头为旋转中心的定位云台就可以避开旋转中心位置的拍摄死角。

In order to folding a door body to revolve radius small, the door can make use of well after opening with door hole for center before behind space, so fold door applicably in the mansion hallway, industrial factory premises, warehouse, etc.

由于折叠门门体的旋转半径小，门开启后可充分利用以门洞为中心之前后空间，因此折叠门可适用于大楼走廊、工业厂房、仓库、等需要较大有效宽度的地方。

The invention contains following apparatus: display main body; base setting a combination groove thereon; a frame for connecting the display main body and base; rotating apparatus setting under the frame and connecting on the combination groove of the frame for making the frame left-and-right rotate relative to the base; an inclination preventing element for prevent the frame up-and-down inclination with the rotatable gemel as center.

本发明包含下述装置：显示器主体；在其上面设置了结合槽的底座；用于连接上述显示器主体和底座的支架；设置在上述支架的下侧，结合在上述支架的结合槽上，使支架能够相对上述底座进行左右转动的旋转装置；用于防止上述支架以旋转铰链为中心上下倾斜的倾斜防止元件。

A latchet has an engagement piece for operation and rotatable about a pulley shaft for the pulley is supported on the base.

在基座上支承有棘轮，该棘轮设置有工作用卡合件，并且该棘轮能以绳轮的绳轮轴为中心旋转。

In summary, we used the following tools during this study: 183 degree fish-eye lens, the rotation tripod which takes the lens as the center of rotation and the self-developed software which can transform the fish eye image to the spherical panorama images. The whole spherical panorama images can then be created seamlessly and conveniently for the real estate usage on the Internet and some case studies are shown in this thesis.

总而言之，使用183度鱼眼广角镜头、以镜头为旋转中心的定位云台和将广角影像转换成球形全景影像的制作软体，就可以方便地将某空间各角度的影像撷取至球形全景影像，完整的制作过程可以变得相当简易及平顺，并且基於本研究所制作的房地产实例也证实了本研究的实用性。

By incorporating all these seeting on the aswirl board with the optimal gantry angle, the patient will final accumulate compensated dosages on whole body surface.

结论与讨论：结果显示以在等中心旋转点处照野为40cm×40cm，当加速器的机头水平往上及水平往下各155。

By focusing on the coupling of water and fertilizer and using all-purpose regression design with four factors and five levels, and based on pot experiments and quantitative analysis, the coupling effect of water and fertilizer on Casuarina equsetifolia biomass was studied in order to solve the inconsistency problem of water and fertilizer supply on coastal sandy land.

针对滨海沙地因水肥不协调而形成大面积低效林分的问题，以水肥耦合为中心，以1年生木麻黄幼苗为研究对象，采用四因子五水平二次通用旋转组合设计，利用盆栽试验和定量分析的方法，研究探讨了在不同水肥条件下，水、N、P、K四因子对木麻黄生物量的影响。

The dynamo runs at rull speed to drive main shaft,then the main shaft makes the emulsifying wings in emulsification grove rotate,which absorbs the liquid in its brand groove into ring groove through guide vanes on upper and lower side s of the groove.The v

由电动机全速运转带动主轴，经主轴转动乳化框槽内之乳化翼片，使其将桶槽内之液体经框槽上、下两侧之导流叶片吸入环状框槽内，经以主轴为中心高速圆周旋转叶片；连续使乳化翼端刀面与乳化框间极小之间系高频率之强力切割剪断、粉碎，再借叶片高速离心旋转排挤，持续循环混合，以极短之时间即可完成均质乳化之处理。

One: It must be orbited the sun.
