对利用沉积记录来研究海平面变化的重视程度很高，但对海平面变化对沉积盆地的影响注意甚少。建议关注海平面升降变化对盆地充填物的作用，对沉积型矿床的控制和对大陆边缘地壳变形的反弹作用过程的研究及定量模拟是一个重要方向，它可能为大陆边缘动力学研究提供一方面的思路。

The analysis of sequence genesis shows that the eustasy is main factor of the forming sequence, since this is a continental marginal basin with ramp, the incised valley and its fillings in lowstand system tract was absent in most of sequence.

层序成因分析表明海平面变化是控制层序形成的主要因素，盆地古地理背景基本为一缓坡边缘，低水位深切谷及其充填沉积的普遍缺失可能与此有关。

By theoretical analysis and experiment, the productivity of well completion with expansion screen pipe is studied and compared with conventional mechanical sand control completion.

结合理论分析和实验研究了膨胀筛管完井后产能，并对比了一般机械防砂方式，以独立筛管完井和砾石充填完井为例进行了对比计算。

The ignition of the solid rocket motor is a very complex physical and chemistry process, which is composed of three component phases: ignition delay, flame spreading and chamber filling.

固体火箭发动机的点火是一个十分复杂的物理化学过程，包括三个阶段：点火延迟、火焰传播和燃烧室气体充填。
