The film or movie is the most popular and common video resource. In this paper we use the film video as an example, aims to implement real-time retrieve of explosion and shot scenes, has carried on the following research mainly: first, we proposed a method of real-time recognition of explosions based on dominate-color and audio information and improved the accuracy the retrieve;second, we proposed a method of real-time retrieve of shots scenes based on audio information and differences between frames when the shot occurs;third,a whole video abstraction system is proposed, it can cut off the clips which have been retrieved and merge them into a independent video abstraction in the same time edit the information of the it ;forth, it offers two-level retrieval structure of"key frame-highlights"and can play segmentation result and the whole video just like a video player.

Some Thinking of Quantitative Study on Interaction between Explosive Charge and Rock: Because of the non-linear property and the variety of rock, the instantaneity of chemical action of explosive, the complexity of the dynamic process of the interaction between explosive and rock and the limitations of the observation measurements, the former research results mainly focused on the explanation and description to the apparent phenomena, and difficult to obtain the accurate and quantitative answers.

爆炸荷载与岩体相互作用定量化研究的几点思考：由于岩体自身的非均质性及各向异性和地质构造的多样性、炸药爆炸本身的化学反应的多变性和瞬时性、炸药与岩体相互作用的复杂性，加之爆破测试方法和仪器的局限性，使得以往的研究多沿用经典理论集中于表面现象的描述与解释，难以获得完整的、准确的和定量的解答，必须从一个全新的角度研究探索爆炸荷载与岩体相互作用的本质。

I feel a mere explosion which topples others is not quite the best way to show the death of a unique monster.There is already tons of explosions in the game, I feel they should be set apart some other way insted of making it bigger.

不过我感觉爆炸效果并不是最理想的表现方式，因为游戏中已经有很多的爆炸特效了，我觉得应该换一种表现形式，而不是把爆炸做的更猛烈。
