The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。

Designers at Inovaxion present the Woodstation:" human-sized French company, INOVAXION, and a high-quality Chinese factory, AEROTIME, When you get close to the WoodStation?, a movement sensor will detect you and will automatically the product's screen through the wood to give you information.… based on coloured luminous icons given through the wood screen and activated by a simple motion of the hand. In lighted mode, this powerful device will track fluctuations of barometric pressure, indoor relative temperature and indoor relative hygrometry data to provide you the weather forecast 12 to 24 hours in advance. The product also manages Hour, Calendar and Alarm clock functions. Big colored icons show sunny - partly cloudy - cloudy - rainy / snowy and stormy. Hour, Calendar, and Alarm clock are shown in red. This practical and useful product is suitable for both A/C Adaptor and batteries, which gives you the option to show it everywhere."

WoodStation有枫木和核桃木两种材质，额头上有一个探头，平时，它那拉长的马脸就像块木头疙瘩(当然，人家本身就是木头疙瘩……)，面无表情，但是，一旦你用手在探头前晃一晃，那张脸马上就活跃了起来，包括时间、日历、温度和湿度等信息会魔法般瞬间浮现在木头上，而且即便是在太阳光直射的情况下，所有读数都清晰可见——根据一些未经证实的第三方资料，这种显示并不是在木头背后埋LED那么没有技术含量，而是某种特别的涂层，相当是马脸的面膜~更赞的是，这些数据不是为显示而显示，它还能分析这些数据，并用直观的图形化方式给出未来24小时的天气预报！

Chapter 1 we introduce the risk process with positive and negative risk sums,show the background of the risk process. Chapter 2 we show the integral and differential equation of birth probability,give the Lundberg inequation that the ruin probability satisfies with martingale approach,then discuss then ruin probability of the risk process with two dependent positive and negative risk sums,study how the dependence impacts on the ruin probability. Chapter 3 we compare the concrete examples by numbers,and makes further comparison between the two results coming out of independency and dependency,with the purpose of narrating their respective impacts on the probability of ruin probability.

本文第一章引入含正、负风险和的风险模型，介绍风险过程的实际背景；第二章给出生存概率Φ所满足的积分-微分方程，利用典型鞅方法给出破产概率Ψ满足的Lundberg不等式，并且讨论两个相关正、负风险和模型的破产概率，研究相关性对破产概率的影响；第三章对具体实例给出数值比较，进一步把相关性和独立性两种情形的结果进行比较，说明对破产概率的影响。

The results for fracture show that the difference between finite and infinitesimal deformation only exists in the vicinity very close to crack tip.

结果显示通过改变材料常数大变形和小变形都可以和微压痕实验结果吻合好，大小变形理论在断裂问题上的区别仅仅存在于非常靠近裂纹尖端处。

In chapter four, we study the second isoperimetric connectivity of line graphs and line digraphs. For line digraphs, we show that the second isoperimetric connectivity of strongly connected line digraphs with δ≥ 2 equals its connectivity. For line graphs, we give a sufficient and necessary condition for the existence of the second isoperimetric connectivity, and we show that under the condition that the second isoperimetric connectivity exists, the second isoperimetric con
