Target tracking is to establish the target relation between image sequences and verify movement of target such as appearance, disappearance, occlusions and speed of target.

运动目标跟踪是指在整个视频序列中建立运动目标序列间的对应关系，判断目标的运动情况例如目标的出现、消失、遮挡，目标的速度等。

The favorable conditions for petroleum accumulation due to volcanic activity and igneous rocks formed during the activity show in two aspects. A The contact surface of igneous rocks and the surrounding sedimentary rocks, like a vertical unconformity surface, formed the conduit of petroleum migration.Petroleum would accumulate once it encountered a trap in which the reservoir had fine porosity and permeability. B It formed a trap barriered by igneous rocks, or changed or cut the original trap.

火山活动以及由此形成的火成岩体对油气聚集的有利条件主要体现在两个方面：一是沿火成岩与围岩的接触面构成油气运移的通道，火成岩与围岩接触，似一直立的不整合面，与孔渗性好的岩层组合不仅能使油气运移而且遇有圈闭油气还会聚集成藏；二是构成火山岩遮挡的圈闭，或是对原有圈闭进行改造、分割。

At this time, the table in front of your board down, one hand holding a pretend flight magazine, the actual role played shelter.
