由螺旋器控制可以精确地确定自由端的位移量；
Displacement can be accurately confirmed by controlling the screw.
另外，通过静态模式下的有限元计算，发现各种梁自由端的偏移量相同，表明它们的静态灵敏度与形状无关。
The deflection of each type of cantilever beams in the static mode keeps constant, which demonstratest.
缺乏数据库级别的安全模型使得充分利用 ZEO 存储服务器变得非常困难，因为客户端或多或少地拥有对数据库的自由访问，因此客户端必须受信任。
The lack of a database-level security model makes it difficult to fully leverage ZEO storage servers as clients have more or less unfettered access to the database and must therefore be trusted.
