Firstly, some basic concepts about ECC are introduced;then the scalar multiplication under affine coordinate is discussed, we make a research and analysis of the side channel attack of scalar multiplication used in portable device, give out a new scalar multiplication algorithm which has the advantage of efficiency over other protected algorithm; and an improvement of the standard scalar multiplication algorithm proposed by IEEE1363 is made with the efficiency increasing by about 10%; at last, we deal with the using of complex multiplication in scalar multiplication algorithm, we generalize the methods and deduce a complete computing procedure, with proposing a new method which used several different fast endomorphism ,we give out an approach to boost the scalar multiplication with fast endomorphism.

本文首先介绍了椭圆曲线密码的有关基本概念；其次介绍了椭圆曲线上点的标量乘法在仿射坐标下的计算，对一般便携设备上的椭圆曲线点的标量乘法的边信道攻击做了研究与分析，给出了一种在效率上优于其它可抵抗边信道攻击的标量乘法的新算法，并对IEEE P1363 标准给出的标量乘法做了改进，使得标量乘法的运算效率提高了近10%；最后介绍了利用复乘计算标量乘法的方法，对已有的方法进行总结归纳，得出完整的计算过程，并针对两类超奇异椭圆曲线给出了一种利用多个可快速计算的复乘的标量乘法，得出一类普遍的结果，并给出了进一步用复乘加快标量乘法的思路。

Music is a bridge of communication between human souls is the crystallization of love and friendship is through feelings of autumn is the leaves on the root of the complex is a birdie on the blue sky of the longing, the pursuit of a stream of the sea ...... music to the people's happiness and well-being of life, so that the soul can make a good and healthy emotional up moisture.

音乐是人与人心灵沟通的桥梁，是爱与友谊的结晶，是走过秋季的感情，是绿叶对根的情意，是小鸟对蓝天的向往，是小溪对大海的追求……音乐给了人一生的快乐和幸福，这样，使人的心灵可以因得到美好情感的滋润而健康起来。

Methods of measuring the input components, their prices and output elements are given. We put forward some new methods in measuring components, including composite depreciation rate, equality working hours, and proxy of input resources. Using the mature methods of efficiency measurement and decomposition available, we make a detailed investigation into 4 listing companies of oil industry with a span of 12 periods. Basic conclusions we draw include: labor inputs affects oil field output mostly in China; China oil fields operates in a low technical efficiency level average of 0.61; Increasing difficulties with expanding output has the greatest influence on cost; Cost efficiency of China oil fields averages at 1.47; Total factor productivity of China oil fields averages at 10%, accounting for 79% of the total output growth rate of 12.6%; Frontier technology progress contributes the most to TFP of China oil fields with 17 percentage points.

本文沿用了已有文献中关于效率计量与分解的成熟方法，对我国三家油田上市公司与一家上市石油公司12个时期的技术效率与成本效率进行了详细的计量、分解与分析，得到的基本结论有：劳动力投入是影响我国油田上市公司产出的最重要的影响因素；油田的平均技术效率仅为0.61；产出项是影响成本的显著因素，这说明随着产出增加而出现的开采难度增加是导致开采成本增加的重要因素；油田的平均成本效率为1.47；全要素生产率的增长平均在10％左右，占到了产出平均增长率12.6％的79％，表明我国油田的生产率的提高主要是依靠全要素生产率的提高而实现的，只有21％左右的产出增长是依靠要素投入而实现的；前沿技术进步是油田全要素生产率增长的主要源泉，在2001～2004年期间，前沿技术进步对油田生产率的贡献高达17个百分点。

On the other hand utterances of Severus which make Christ's sufferings voluntarily permitted, rather than naturally necessitated by the treatment inflicted on His Body, might perhaps be defended by the consideration that from the union and consequent Beatific Vision in the Soul of Christ, would congruously ensue a beatification of the Soul and a spiritualizing of the Body, as was actually the case after the Resurrection; from this point of view it is true that the possibility of the Humanity is voluntary (that is, decreed by the Divine will) and not due to it in the state which is connatural to it after the union; although the Human Nature is of its own nature passible apart from the union St.

另一方面言论的塞维鲁，使基督的苦难允许自愿，而不是自然所必需的治疗对他的身体，或许可以捍卫的审议，从工会和由此幸福的远景在基督的灵魂，将随之congruously 1宣福灵魂和spiritualizing的机构，如实际情况后复活，从这个角度看这是事实的可能性人性是自愿的，而不是由於它在该州是它固有的工会后，虽然人的本质是其本身的性质passible除了工会（圣托马斯岛，三，问：十四，字母a。
