To characterize the distribution of blood pressure, prevalence, and risk factors for hypertension in pediatric chronic kidney disease, we conducted a cross-sectional analysis of baseline BPs in 432 children (mean age 11 years; 60% male; mean glomerular filtration rate 44 mL/min per 1.73 m2) enrolled in the Chronic Kidney Disease in Children cohort study. BPs were obtained using an aneroid sphygmomanometer.

According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。

The poly-culture biomass of silver carp and bighead carp played an important role during biomanipulation in case of no extraneous nutrient addition, which depended on the actual productivity of water body. So it is favorable to improve biomanipualtion of fish to choice the stocking biomass according to productivity of water body.

鱼类的生物量对其生物操纵作用的发挥有重要的影响，水体中鲢、鳙适宜生物量的选择是由水体中生产力水平决定的，根据水体的实际生产力水平来选择鲢、鳙的生物量，有利于其生物操纵作用的发挥。

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

The authors choose the proper regress methodology ac- cording to the characteristics of our panel data.

在根据面板数据本身的特征选择适宜回归技术的基础上，通过研究发现，在通过家族控股上市而形成的民营上市公司中，年度内董事会会议次数对企业的市场价值有显著的正向影响，而在通过兼并重组取得控股地位的民营上市公司中，这种影响并不显著；在考虑控股股东现金流权与投票权分离程度的调节作用后发现，随着控股股东现金流权与投票权分离程度的提高，年度内董事会召开会议次数的增加有利于企业市场价值的增加。

The coordinate transformation and numerical integration was executed on the discretized tetrahedral elements based on which the 3-D MT vector-finite element method was implemented. A whole computation framework for 3-D vector-finite element method with unstructured mesh was given. Based on this some typical models were tested which has demonstrated that our algorithm could distinctively avoid problems caused by the fake solution and both the accuracy and efficiency were enhanced which made our algorithm has a bright future for further application.3. According to theory of Sobolev vector space and the discretization of Helmholtz space, the error estimate which was suitable for 3-D MT vector-finite element modeling was deduced by which the procedure of adaptive technique was guaranteed.4. Based on the fully unstructured tetrahedralization and optical strategy, the 3-D magnetotelluric h-adaptive vector-finite element method was presented through combining the error estimate.

When production costs fluctuate and yet,at the same time,selling price can not be adjusted because it is determined by the equilibrium of the entire market,at the aggregate level,where different players have different cost advantages in different products and processes. We show that the variational inequality approach is suitable for dealing with this differential game.

当产品生产成本大幅波动时，产品的销售价格并不能完全的由单独的生产商随意根据自身成本变动调整，因为在寡头垄断市场中，产品的最终售价须由市场的所有参与者共同确定，而不同的厂商在不同的产品与工艺流程中有不同的竞争成本优势。

A conspiracy theory is the belief and empirical hypothesis that historical or current events are the result of manipulations by one or more secretive powers or conspiracies Because conspiracy theories are frequently difficult to support with evidence, they are used as derogatory words According to Karl Popper's philosophy of science and falsifiability criteria, conspiracy is not a science But in reality, conspiracy theories are not all baseless, irrational and deceptive

阴谋理论是一种信仰，也是一种经验假设，认定某些事件是由一个或几个有势力的秘密组织阴谋操控、秘密实施产生的结果。由于阴谋理论往往很难得到事实的佐证，因此成为一个贬义用语。按照波普的科学哲学观与检验理论科学性的标准，阴谋理论并非科学。但事实上，阴谋理论并非是无根据的、非理性的、虚伪的。
