发现板在两端简支、中点联结松动时，结构首先出现屈曲失稳，而不会发生颤振失稳。
For pined_pined, loosed midpoint support plate, it is found that the plate's buckling instability will happen first while the flutter instability will disappear.

两块板端应该搭接，搭接长度大约为工厂预制槽的一半(搭接时注意当地的常年风向)。
Two boards should end lap, lap length about half the prefabricated groove for the factory.
钢丝绳向新的一层过渡时，对端侧板产生轴向推力，导致侧板弯曲，同时在侧板与筒壁过渡处产生较大应力。
The axial force toward the side board is always produced when the wire rope reaches the new layer. It makes the side board bended and causes very large stress between the side board and the roller.
试验和理论分析表明：梁柱节点分别为焊接连接、端板连接、角钢焊接时，其结构的周期依次增大；
The test and analysis show that the period of frames in- crease in turn for the weld connection's, the end-plate connection's and the angle connection's steel frame respectively.
开关的进线端和出线端是铜垫块时，铜垫块和联接板之间连接有软母线。
If the incoming and outgoing line ends are copper spacers, the soft bus connects the copper pad with the coupling panel.
