此外，还对反弯曲线曲率和等曲率区长度的选取作了说明，指出在等曲率弯曲区只能使曲率均匀化，而真正实现矫正是在后部的非等曲率弯曲区，这是对矫正理论的深入和完善，并且这一研究方法也可推广到棒材矫正机。

Based on the analyses of the observation data and numerical model of ocean circulation, the variations of the Kuroshio in Luzon strait (included Bashi strait and Balintang strait) have been studied by using the theories of potential vorticity conservation and oceanic Rossby wave; It was first discovered that the climatologic mean state of the Kuroshio exhibits a westward bending through the Luzon strait. The location of the Kuroshio bending is limited to the east of 119E and frequently flanked by a cold eddy to southwest of the Kuroshio; This bending of the Kuroshio favors the formation of the anticycle eddy in the east of the Luzon strait.

依据对海洋观测资料的分析，运用位涡守恒，海洋Rossby波动理论和数值模式，研究了黑潮在吕宋海峡（包括巴士海峡和巴林塘海峡）的形变特征；首次确定了在吕宋海峡黑潮的形变的平均状态是黑潮向南海的弯曲，该弯曲西端位置一般不超过119E，该弯曲的西南侧常常出现冷涡；该弯曲有利于吕宋海峡东侧形成一个反气旋涡旋。
