關聯規則挖掘作為數據挖掘的核心任務之一，由於其任務本身的復雜性通常需要多次整個掃描數據庫才能完成挖掘任務且頻繁模式可能產生組合爆炸，使得從原始的大規模數據集上抽取一部分樣本，在其上尋找用戶感興趣的近似規則成為目前提高演算法效率和可擴展性的一種簡單有效的現實可行方法之一。Research on mechanical sensor for measuring explosive damage in the near field
機械傳感器測量炸藥近爆區爆炸破壞作用實驗研究Two - order enhanced un - split finite volume euler method for multi - fluid flow, which combines the roe approximate riemann solver, is developed to simulate the multi - fluid interactions, such as the fluid described by polynomial eos, stiffen gas eos, jones - wilkins - lee ( jwl ) gaseous explosive eos, cochran - chan ( cc ) solid explosive eos and hom shock wave eos, etc. numerical results of the id, 2d and 3d multi - fluid interaction examples show that the high - resolution method and interface capturing equations can resolve the multi - fluid flow correctly and successfully. a simple fluid - mixture type ppm algorithm for multi - fluid flow, which is based on vof interface capturing method and resolved by langange / remap two steps, is developed to simulate the high density or high pressure ratio flow at both sides of the interface
本文提出了實用於多介質流體的增強型二階精度有限體積歐拉數值計算方法，採用roe方法近似求解riemann問題，可以適用於多項式狀態方程、 「 stiffengas 」狀態方程、 jones - wilkins - lee爆轟產物狀態方程、 cochran - chan固體炸藥狀態方程以及hom狀態方程等，並對多介質流體相互作用的一維、二維、三維問題進行數值計算，數值驗證了本文給出的高精度差分格式和界面捕捉方法的正確性，兩種方法耦合形成的多介質流體數值計算方法是成功的。Data mining is a field developing rapidly in recent years. today, with exploding information, it even displays the huge function and powers
數據挖掘是近年來蓬勃發展的一個研究領域，在信息爆炸的今天，它更顯示出巨大的作用和威力。The modern terrorism form, was different with the ancient times terrorism assassination, poisoning, and also different from modern terrorism state terrorism, but full of the bloody explosions, hijacking, murder, etc. terrorism has been the development of modern forms of violence no longer a simple, cyber - terrorism as a new form of terrorism on the stage of history, and its activities to take full advantage of the network as a tool and weapon, with high intelligence and uncontrollable characteristics
現代恐怖主義的形式，不同於古代恐怖主義的刺殺、投毒，也不同於近代恐怖主義典型的國家恐怖主義，而是充滿血腥地爆炸、劫機、屠殺等。近代恐怖主義發展至今已經不再是單純的暴力形式，網路恐怖主義作為一種新的恐怖主義形式登上了歷史舞臺，其活動充分利用網路作為工具和武器，具有高智能化和不可控制的特點。Conducting electrostatic coating, a new kind of functional coating, has been rapidly developed in the past two decades. it is mainly used in the petroleum storage facilities and can prevent the fire hazard and explosion caused by electrostatic charge
