由于高强度钢材的屈服极限不断地增大，下潜深度的不断增加，弯曲微分方程解的形式将不仅限于复数解。
Increasing the yield limit of high strength steel, and increasing the depth of submergence, the form of the differential equation's result will not only be limited with the complex number.
超远投的距离使我能让饵的下潜深度超出其规定的20英尺（约6米），而线的高感度让我能感觉到饵的姿态以及它所撞到的鱼。
The length of the cast made it possible for me to push the lure beyond its prescribed 20-foot depths, and the sensitive line helped me feel the bait and the fish it was bumping.
