In Chapter 4, the pricing of Asian geometric average option under stochastic interest rates is studied, assuming CIR model for the interest rates. Asian option is strongly dependent with path, usually have a long duration, the movement of interest rates becomes more important in pricing such long-dated options. The CIR interest rate model not only considered the interest rate behavior has mean-reverting but also take into account that the fluctuation rate is direct proportion with the square root of its interest rate. Finally, the method of finite difference for the Asian geometric average option under CIR interest rate model is given.

第四章在利率满足CIR利率模型的假设下，研究了几何亚式期权的定价公式，亚式期权是强路经依赖性期权，通常有效期较长，在进行较长时期的投资时，利率的变化是非常重要的，CIR利率模型不仅考虑了利率行为具有均数回归的现象，而且还考虑其波动性的大小与利率大小的平方根成正比，最后给出了CIR利率模型下的几何亚式期权定价的有限差分法。

Methods The data of 152 patients with colorectal carcinoma of Bultrasound, airbarium double contrast examination, colonoscope and spiral CT were retrospectively analyzed. The detective rate, the diagnose accordance rate, detection rate located coincident rate and absorbent gland metabasis rate were compared.

回顾性分析152例结直肠癌患者的B超、气钡双对比造影、结肠镜、螺旋CT扫描等四种检查资料，统计四种影像学检查的病灶发现率、肠癌诊断符合率、肿瘤部位检查符合率、淋巴结转移检出率。

The detective rate, the diagnose accordance rate, detection rate located coincident rate and absorbent gland metabasis rate were compared.

结果 B超、气钡双对比造影、结肠镜、螺旋CT扫描对病灶的发现率分别为64.5%、92.6%、94.1%、88.9%，诊断符合率分别为50.6%、83.6%、89.6%、80.2%，B超与另三种检查比较，病灶发现率、肠癌诊断符合率有显著性差异；肿瘤部位检查符合率四种检查无差异；B超和螺旋CT的淋巴结转移检出率有显著差异。

The results showed that the grain yield of winter wheat with two-irrigation was higher than that with one-irrigation with the same nitrogen application rate and method. Compared to one-irrigation,the grain number per spike in two-irrigation was higher,the 1000-grain weight was lower, the water wastage was higher, but the WUE was lower. The yield was not affected significantly by nitrogen rates and the methods. Within the nitrogen rate of 157.5-295.5kg/hm2, the lower NUPE and Nitrogen Productivity declined with nitrogen rate increasing. NHI was not lower than the others at the lowest nitrogen rate of 157.5kg/hm2. The accumulation of NO3--N in soil was significantly and positively correlated with the nitrogen application rate. NO3--N in one-irrigation was distributed mainly in the top layer (0-80cm), but it was inverse in two-irrigation.

结果表明，施氮量和施氮方式相同时春浇二水冬小麦的产量高于春浇一水，二水穗粒数较一水高，千粒重则低于一水，一水耗水量较少，水分利用效率明显高于二水；同一水分下不同施肥量及施肥方式对产量的影响差异不显著，同一施肥方式下在157.5-295.5kg/hm2范围内，施肥量越大，氮素生理效率和氮肥生产力越低，施氮157.5kg/hm2时，氮收获指数均处在最高或较高水平；土壤硝态氮残留量与施氮量呈显著正相关，成熟期一水条件下土壤中硝态氮主要集中在上层(0~80cm)，二水条件下则主要分布在中下层。

By using a fracture simulation unit,the regularity that temperature,flow rate and fracture width influence on HCl/dolomite reaction rate is investigated.The sequence of temperature,flow rate,acid concentration and fracture width influence to the acidic rock reaction rate is also studied in a four factors and four levels orthonormal test,and the sequence that acid concentration＞flow rate＞temperature＞fracture width is found.At the last,the possible HCl/dolomite reaction mechanism model which can explain the influence factors is derived.
