The outside sea wave streams into near the shore and shallow water area, being subjected to a submarine friction function, the wave 锋 becomes abrupt, the trough of wave become slowly, the fluid matter orders sport track to present back and forth fluxion, and to shore enter the current velocity degree is usually bigger than offshore reflux speed, causing bottom sediment clean to shore porterage, and is aroused a shore wave of ascend the blunt water current take to the seashore on-line pile up.

外海波浪传入近岸浅水区，受到海底的摩擦作用，波锋变陡、波谷变缓，水质点运动轨迹呈现往复流动，而且向岸进流速度通常大于离岸回流速度，导致底部泥沙净向岸搬运，并被激岸浪的上冲水流带至海滨线上堆积。

Studied pumping well system in this article, the intermediate power transmission parts uesed flexible rod, the downhole assembled rod pump, the ground driving device would transform up and down reciprocating motion into rotating motion. With own mechanism rounded trip for the downhole flexible rod and pump. Wellhead polished rod changed common stell for flexible polished rod. It was a innovation in theory study and craftwork method. It was a remarkable feature in this article, because these innovations were not studied and attempted for prehuman.

本文所研究的抽油系统，中间动力传动部件采用柔性抽油杆，井下配套杆式抽油泵，其地面驱动装置将传统抽油机驴头的上下往复运动变为旋转运动，并且能够利用自身结构对井下柔性抽油杆及泵体实现起下作业，井口光杆也由普通钢质光杆变为柔性光杆，这是理论研究和工艺方法的创新，这些创新都是前人所没有研究和尝试的，是本文的一大显著特点。
