objective to compare four postoperative nasal packing materials.methods total 136 patients,80 cases with chronic sinus it is and under went endoscopic sinussurgery,were randomly packed using four different hae mostasis materials.in which,paraffin gauze group was 40 cases,rapid sorbalgon group 27 cases,merocel group 36 cases and gel knit group 31 cases.the packing materials wereemoved after left for 24 hours to 48 hours.the efficacy of nasal packing materials was asassessed interm of the levels of nasal pain or headache in the leaving period and nasal bleeding after removal of nasal packing.results the in cidence rate of nasal pain or headache respectively was 82.5% in paraffin gauze group,44.4% in merocel,11.1% in sorbalgon and 3.2% in gel knit.the significant statistical difference was observedbetween the four groups (χ2=70.21,p.01).the incidence rate of nasal bleeding after removed was 85%,11.1%,41.7% and 9.7% respectively.the statistical difference was also significant (χ2=54.28,p.01).conclusions the choosing of postoperative na sal packing after functional endoscopic sinus sur gey depends on various factors,gel knit has much advantages and can be used as routine packs after fess.

摘 要］目的：比较四种鼻腔填塞材料的疗效，指导临床选择合适的术后鼻内填塞物。方法：对134例慢性鼻窦炎分别采用凡士林纱条(40例)、藻酸钙纤维(sorbalgon，27例)、膨胀海绵(merocel，36例)和瑞纳凝胶快速止血材料(gel knit，31例)四种材料填塞鼻腔，24 h～48 h取出填塞物，根据填塞后鼻腔胀痛、头痛程度，取出填塞物后鼻腔出血程度等评价疗效。结果：凡士林纱条填塞组，82.5%有鼻腔胀痛或头痛；sorbalgon藻酸钙纤维组11.1%；merocel组44.4%；gel knit组3.2%，四组比较差异非常显著(χ2=70.21，p.01)。取出填塞物后鼻腔再出血分别为85%，11.1%，41.7%和9.7%，四组比较差异非常显著(χ2=54.28，p.01)。结论：鼻内镜手术时，应综合考虑诸方面因素合理选用术后填塞物。瑞纳优势较为全面，可作为鼻内镜手术的常规填塞材料。

Due to the inveracity of statistical probability with little sample of disasters, the mutation progression was used to calculate the probability instead of the statistical probability and fuzzy degree instead of brittle events' value.

鉴于小样本灾害事件统计概率的不准确性，用突变级数法计算的脆性因子突变概率代替脆性风险熵计算中的统计概率，模糊数代替脆性事件结果价值。

Kinetic theory of gases is the Gibbs statistical mechanics on the material before the advent of thermal motion of the micro-theory, which later became part of statistical mechanics, and contributed to its development .1658 year, Jia Sangdi proposed substance is formed by a molecular hypothesis.

气体动理论是吉布斯统计力学出现之前的关于物质热运动的微观理论，后来成为统计力学的一部分，并促进了它的发展。1658年，伽桑迪提出物质是由分子构成的假说。

Based on the method of restoring the image by estimating the camera shake trace which is proposed by Fergus in 2006 as reference, we find the difference of statistical characteristics between blurred images and latent images by exploiting the natural image statistical characteristics more deeply, i.e. the precise components of natural clear images obey the Laplace distribution in their wavelet domain, but blurred images dont have this kind of characteristic.

本文参考了2006年Fergus提出的估计相机抖动轨迹进行复原的方法，通过进一步对自然图像统计特性的研究，寻找出模糊图像和清晰图像在统计特性上的差异，即清晰图像的小波域细节分量服从拉普拉斯分布，而模糊图像则不具有这种特性。

This paper has carried on the discussions about some key questions of multivariate statistical modeling, such as choice of statistical variable, the system linear approximation and the noise influence and so on.

We obtain the risk process involved in this model,the statistical properties of the surplus process,and statistical features of the claim numbers and the probability distribution of the total amount of compensation.The three types of business of the risk model is given when the number of claims obey Poisson distribution and negative binomial distribution.We make a comparison between the risk model built in the thesis and the classic risk models with independent claim numbers when the amount of claims obey Weillbull distribution and Exponential distribution.The results have a good practical significance.

其次，考虑不同险种间的相互关系，建立了一种含有主副理赔的风险分析模型；借助随机过程和经典风险理论，对该风险模型所涉及的风险过程、盈余过程的统计特性以及理赔总额的概率分布、数字特征和矩母函数进行解析研究，给出了主理赔次数服从泊松分布和负二项分布的这种风险模型的具体实例，并在理赔额变量服从Weillbul分布和Exponential分布的情况下，把文中所建风险模型和理赔次数相互独立的风险模型作了比较，所得结果有很好的现实意义。
