It is also discussed that the Ag powder was added into the electrode by utilizing the decomposition of AgNO_3, but the result is not so good. Scanning by SEM, the active material is broken with long time mixture or temperature is insufficient to decompose completely. The mixed conductive additive was put into the active material LiFePO_4 to improve the conductivity.

本论文还试探性的利用AgNO_3的高温分解性在电极中添加Ag粉，但结果却不令人满意，通过对机械球磨后的电池材料进行SEM扫描分析，发现电池容量衰减的原因是长时间的机械球磨使得活性物质的晶体破裂，还有一点可能是因为温度不够高，AgNO_3分解的不彻底，使得电池中还存在着AgNO_3，影响了电池的性能。

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.

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。
