However, after the continuous box girder bridge\'s massive uses, the prevalence of box-girder web cracks becomes the outstanding obstacle to their development and has become a focus of concern in engineering academic.
但是,在连续刚构桥箱梁大量的使用以后,普遍存在的箱梁腹板裂缝问题成为了阻碍其发展的突出问题,也成为学术界、工程界关注的一个焦点。
This article takes the flange nut as an example,discusses the technique of cold extruding seamless pipe to make large flange nut and the feasibility of the technique.

A new seamless integrated navigation algorithm was proposed on the basis of ANFIS in order to enhance the performance of GPS/INS integrated navigation system during GPS outages.
针对GPS卫星信号失锁条件下GPS/INS组合导航性能大幅度下降的缺点,设计了一种基于ANFIS的无缝组合导航方法,当卫星数目不低于4颗时采用伪距/伪距率的卡尔曼滤波算法,一旦卫星数目少于4颗时采用ANFIS系统估计导航误差,抑制INS的误差积累,从而实现无缝导航。
