The microdosimetric spectrum and radial dose distribution of 16O＋ particles with energy 109 keV generated from small low energy heavy ion accelerator permeating through PET film (C10H8O4) with thickness of 4 μm are measured by the cylindrical tissue-equivalent proportional counter.

用圆柱型流气式组织等效正比计数器测定了K-200 kV低能重离子加速器提供的低能16O＋离子束流在穿过4 μm厚的PET（C10H8O4）薄膜后的微剂量谱和径向剂量分布。

Oxygen was found to depress their fcc-sctransition temperature Tc from the normal value of 260K,as indicated by theminimum in the temperature-dependent permittivity ε′,and also enlarge the drop in ε′at the transition.The magnitudes of the downward shift in Tc and the drop in ε′were roughly proportional to the O2 occupance at octahedral lattice sites,as estimatedfrom the resonance heights distribution.

发现氧的存在降低了以介电常数ε'温度谱极小值为标志的有序无序相变温Tc(正常相变温度为260K)，并且增大了ε'在相变前后的变化幅度，Tc的下降值和ε'的变化量Δε'近似比例于八面体位置氧的占据率，氧的占据率可以从核磁共振峰高的分布获得。

The results show that soil-root complex still comply with Coulombs law; root-soil complex cohesion and the incremen in the unit soil content directly proportional relationship, and the root system anchoring role formula is established based on this; Different distribution methods in root has different impact on the shear strength of composite material.

结果表明，根土复合体仍然符合库伦定律；根土复合体粘聚力的增量与单位土体中根系的含量成正比关系，在此基础上建立了根系锚固作用公式；根系不同的分布方式对根土复合体的抗剪强度有不同影响。

To compare the performance with PN, the trajectory simulation is carried out, and the results show that the new guidance law provides significant performance improvements over the commonly used classical proportional navigation law, the load distribution among the trajectory is reasonable and favorable for the hand-over between the mid-course phase and the terminal phase.

在以上内容的基础上，建立了拦截弹末制导有关的六自由度数学模型和仿真模型，对不同初始条件下拦截飞机和战术弹道导弹进行了数字仿真，分析了拦截高速弹头时弹道的新特点，并采用蒙特卡洛法分析了不同误差因素作用下的制导精度。

Chapter one of this text has recommended the foreign insurance to apply financial economy to the products pricing method of insurance company, but these methods have not explained how to determine the fair premium of the multiple-line insurance company .In order to solve many business line insurance company pricing problem, chapter two introduce an very important model in insurance company capital allocation field - MR capital allocation model, through deriving capital allocation formula and simulation analysis indicate MR model allocate multiple- line insurance company capital scientifically. In order to apply MR model to non-life insurance pricing, chapter three will extend MR model to introduce loss 3 and layer P . Since the premise of MR model is a certain market price of loss, the chapter four will use the risk-neutral probability transformation technique to get the market value of loss. Under lognormal distribution, we will use location parameter shift and proportional PH transformation to illuminate the technique. The final chapter combines the prior sections result to deduce out the fair premium formula, and apply it to price the catastrophe insurance.

本文的第一章介绍了国外保险业将财务经济学应用到保险公司产品定价的方法，但是这些方法都没有说明如何确定多业务线保险公司的公平保费；为了解决多业务线保险公司定价问题，第二章引入保险公司资本配置领域非常重要的一个模型—MR资本配置模型，通过推导资本配置公式及模拟分析表明MR模型科学地配置了多业务线公司的资本；为了将MR模型应用到非寿险公司的定价中去第三章扩展了MR模型，引入了损失β和层β的概念：由于MR模型的前提条件是有一个确定的损失市场价值，第四章利用风险中性转化方法获得损失的市场价值，在损失为对数正态分布的条件下，通过位置参数转化和比例危险转化方法给出了实例说明；第五章结合前几章的结果给出非寿险公司公平保费的定价公式，并运用它给出了巨灾保险价格的模拟分析。

The well-known empirical e-lgσ' relation is introduced into the study on one-dimensional nonlinear consolidation of one-layered soil under cyclic loadings. The corresponding consolidation equation is established with the assumptions that the decrease in permeability of soil is proportional to the decrease in compressibility during the consolidation process and that the distribution of initial effective pressure does not vary with depth.

将孔隙比e与有效应力σ'关系引入循环荷载作用下单层地基的一维非线性固结问题的研究之中，通过假定土体中的初始有效应力沿深度均匀分布和固结过程中上体渗透性的降低与压缩性的减小成正比，建立了低频循环荷载作用下单层地基的一维非线性固结问题的固结方程。
