In general, large-span cable-stayed and suspension bridges require bridge towers with a length of more than tens or hundreds of meters. Due to the unproportionate slenderness ratio, the bridge tower becomes vulnerable to air and thus easy to be distorted or to vibrate, which will affect the stability of the entire bridge structure. Therefore, it is of great significance to carry out an in-depth research on the force feature of the bridge tower in a flow field.

大跨度的斜拉与悬索桥，往往都需要建造数十米甚至上百米的桥塔，过大的长细比，使得桥塔在流场中受到气体的作用容易发生变形或振动，从而影响了整个桥梁结构的稳定性，因此，深入细致地研究桥塔在流场中的受力特性非常有必要。

The Ni and Zn-doped spiculate α-FeOOH were prepared by the coprecipitation method and citric acid method using FeCl2、Zn(NO3)2、Ni(NO3)2 and NaOH as raw material and spiculate α-FeOOH as intermediate.
