In this paper, we introduce the algorithm of Schoof-Elkies-Atkin to compute the order of elliptic curves over finite fields. We give out a fast algorithm to compute the division polynomial f〓 and a primitive point of order 2〓. This paper also gives an improved algorithm in computing elliptic curve scalar multiplication. Using the method of complex multiplication, we find good elliptic curves for use in cryptosystems, and implemented ElGamal public-key scheme based on elliptic curves. As a co-product, we also realized the algorithm to determine primes using Goldwasser-Kilian's theorem. Lastly, the elliptic curve method of integer factorization is discussed. By making some improvement and through properly selected parameters, we successfully factored an integer of 55 digits, which is the product of two 28-digit primes.

本文介绍了计算有限域上椭圆曲线群的阶的Schoof-Elkies-Atkin算法，在具体处理算法过程中，我们给出了计算除多项式f〓的快速算法和寻找2〓阶本原点的快速算法；标量乘法是有关椭圆曲线算法中的最基本运算，本文对[Koe96]中的椭圆曲线标量乘法作了改进，提高了其运算速度；椭圆曲线的参数的选择直接影向到椭圆曲线密码体的安全性，文中利用复乘方法构造了具有良好密码特性的椭圆曲线，并实现了椭圆曲线上ElGamal公钥体制；文中还给出了利用Goldwasser-Kilian定理和椭圆曲线的复乘方法进行素数的确定判别算法；最后讨论了利用椭圆曲线分解整数的方法并进行了某些改进，在PC机上分解了两个28位素数之积的55位整数。

Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。

现代信息技术以建构主义理论为基础，以丰富的表现力、快速的信息传递、交互性强、充分的资源共享性等优势进入课堂，打破了传统的数学课堂教学模式的束缚，使教育的内容、手段和方法发生了根本性的变革。

The result verifies that the discrete model with power series direct discretization method requires 100 memory length to obtain the better approximation, while one with continued fraction direct discretization method requires only 10 order. Thus the continued fraction direct discretization method is preferable to digital realization of fractional order control algorithms in engineering applications.

研究结果表明，幂级数直接离散法得到近似离散模型需要记忆长度为100方可获得较好的近似，而连分式直接离散法近似离散模型为10阶时就可以获得较好的近似，因此连分式直接离散法比较适合于分数阶控制算法的实际工程应用。
