Under coaction of endogenic geological processes and water and heat conditions, the drainage development, and water formation and transformation in the inland watershed. were indicated hydrological characteristics of periglacial zone. The hydrological process is mainly related with to changes in mountain areas. It by 41% of precipitation in mountain areas as surface discharge flows into middle and lower reaches, which makes up a main physical basis of the quantitative and qualitative relationship for various functional units in the eco-system in mountain front plain.

Fist, mode analysis is accomplished, and stiffness influence of the structure by the member parameter and the accessional columns are analysed. Then the numerical value of the pulsoting wind load was used, the time history contrastable analysis between mega-sub controlled structure and general megaframe structure has been accomplished. Finaly, the influence of vibration-controlled efficiency under the different member parameter of vibration-absorption megaframe structure is analysed.

How the conformity resources, does the solution modern city allocation development question, enable the allocation industry to become well promotes the urban development the drainless power, is the urban allocation industry research main topic.

如何更好地整合资源，解决现代城市配送发展问题，使得配送业成为推动城市发展的不竭动力，是城市配送业研究的主要话题。摘要：近年来，配送业的发展与城市规划之间的矛盾已成为城市发展的主要问题。

Induction of apoptosis by Etoposide was associated with upregulation of mRNAs for the BH3 only proteins Noxa, and to a lesser extent, Bim. In contrast, the expression levels of mRNAs for PUMA remained unchanged before and after treatment with Etoposide.

Noxa和PUMA主要受p53调节，细胞DNA损伤后通过p53可以上调Noxa和PUMA的表达［1］； Bim主要结合在微管动力蛋白上，受到细胞因子去除、Ca2+流出、紫外线照射、微管动摇和紫杉醇等刺激后可以转移到线粒体膜上［2］，从而发挥促凋亡活性。

To analyze the dynamic performance of hydraulic hybrid vehicles and to optimize the main design parameters of the hydraulic system, the mathematical models of the hydraulic system are established, which includes bidirectional variable-displacement motor, hydraulic accumulator and other components. The relation between polytropic exponent of bladder accumulator and variation rate of gas volume is defined.

为了分析液驱混合动力车辆的动态特性并优化液压系统的主要设计参数，建立了液压系统双向变量马达、液压蓄能器及其它主要元件的数学模型，定义了气囊式液压蓄能器的多变指数和气体体积变化率之间的关系。

The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

本文尝试一种新型液力泵的设计和开发，它的设计思想是结合有杆泵和无杆泵各自的优点，取消抽油杆，依靠地面液压系统提供动力，本文从抽油泵抽汲原理出发，设计了抽油泵主要部件的结构和尺寸，对上下冲程柱塞的运动规律和泵阀启闭过程进行分析和计算，使用有限元法对主要零件进行了受力分析和强度校核，并设计与之配套使用的地面液压控制系统，考虑深井开采的需要，一并设计了打捞装置，为理论上实现了这种新型液力抽油泵井下开采的可行性和可靠性做了一些基础的工作，本文的设计思路对今后无杆泵采油等类似问题的研究做了有益的尝试。

The result shows that the clay minerals are mainly chlorite, with many years' average quantity being 40%, subordinately kaolinite and illite, and minor smectite.
