In order to investigate the crack propagation in quasi-brittle materials like rock, ceramic and concrete, Hillerborg and his co-researchers abstracted the fracture process zone in front of a stress free crack in terms of a “fictitious crack zone”. On the fictitious crack zone, cohesive stresses distribute following a given softening relationship of stress vs. crack opening. Based on the polynomial or power series expression of cohesive crack opening displacement, the relationship of the cohesive stress vs. the crack opening displacement is established using elastic theory and integral equation, and some unknown physics variables are obtained using variation approach. The calculation results gained in this paper are close to the experimentally test ones.

关键词： cohesive crack, softening, dissipation work, variation approach.

Efficient sensor node localization is a crucial part of many location-dependent applications that utilize wireless sensor networks (WSNs). To cope with the problem of insufficient bea-con node for localization,we design a beacon discovery protocol in this paper that helps the blind node to find beacons nearby and present an energy efficient scheme for the beacon that receives the request from a blind node to adjust its radio range. We obtain the relationship between the mean energy consumption with adjust-ment number by the mathematical analysis. Numerical results show that great energy saving is achieved when the optimal ad-justment number is adopted.

After the new 1︰1000000 aero magnetic data were processed and the three-dimensional inversion work was carried out, a vast high magnetic body northwestward was discovered. The magnetic body is located at the depth of about 20 km on the west side of Tanlu fault and at about 25 km on the east side of Tanlu fault beneath the Sulu area. There is a difference of vertical distance of 3.5 km in depth between both sides. We think that the magnetic body is an Archean metamorphic plate and belongs to the North china block. The discovery of the magnetic body is significant for us to reconstruct the structure model of the Sulu orogenic belt, delineate the suture of collision between the North china block and the Yangtze block, and estimate the depth of slipping surface when the eastside of Tanlu fault moved northward.

目的观察电针夹脊穴对腰椎间盘（IVD）退变（IDD）模型兔髓核细胞沉默信息调节因子1(SIRT1)表达的影响。方法选用25只雄性新西兰兔随机均分为正常组、模型组、假手术组、模型+电针组、模型+假电针组，每组5只。除正常组外，各组通过造模器对L4～L5 IVD轴向加压28天制备IDD模型，其中假手术组仅安装造模器而不轴向加压；造模完成后，正常组、模型组、假手术组正常饲养，模型+电针组行L4、L5双侧夹脊穴电针干预，模型+假电针组仅针刺干预。观察并记录各组兔一般情况、步态功能评分，行磁共振成像（MRI）平扫观察IVD信号并进行Pfirrmann分级，分别采用Western Blot法和免疫组织化学方法检测髓核细胞SIRT1的表达。结果正常组一般情况良好，步态功能正常，磁共振成像呈均匀明亮的高信号，SIRT1蛋白表达丰富，SIRT1阳性细胞较高，假手术组情况与正常组接近（P>0.05）；与正常组比较，模型组一般情况不佳，步态评分显著降低（P<0.05）,IVD信号消失，Pfirrmann分级显著升高（P<0.05）,SIRT1蛋白表达降低（P<0.05）,SIRT1阳性细胞降低（P<0.05）；与模型组比较，模型组+电针组一般情况出现好转，兔精神状态更佳，步态评分显著增加（P<0.05）,IVD信号强度明显增强，Pfirrmann分级降低（P<0.05）,SIRT1蛋白表达升高（P<0.05）,SIRT1阳性细胞增多（P<0.05）；模型+假电针组有一定程度改善，但改善程度水平较低。结论轴向压力可诱导兔腰椎间盘发生退变，而电针能够促进兔髓核细胞SIRT1因子表达，一定程度上延缓细胞衰老，从而抑制腰椎间盘退变。

The geochemical simulation of the formation of brine and salt minerals based on Pitzer model was made in Caka Salt Lake. The evolution of the mixed surface-water and the mineral sequences were calculated and compared with the hydrochemical compositions of the brine and the salt minerals of the deposit in Caka Salt Lake. The results show that the formation temperature of the lake is between 0°C and 5°C, which is well identical with other studies. The mixing of salt-karst water with the surface waters, neglected by the former researchers, is very important to the formation of the lake, indicating that the initial waters resulting in the formation of the lake are multi-source. It is the first time to use Pitzer model in china for making geochemical simulation of the formation and evolution of inland salt lake and satisfactory results have been achieved.

Web search engines are very useful information service tools in the Internet. The current web search engines produce search results relating to the search terms and the actual information collected by them. Since the selections of the search results cannot affect the future ones, they may not cover most people’s interests. In this paper, feedback information produced by the user’s accessing lists will be represented by the rough set and can reconstruct the query string and influence the search results. And thus the search engines can provide self-adaptability.

Nanocapsules with triethylene glycol dimethacrylate （TEGDMA） as core material and polyurethane as wall material used for self-healing bonding resin were prepared by interfacial polycondensation in miniemulsion. The influence of surfactant and costabilizer concentration on nanocapsules size and stability of nanocapsules was investigated. The size and its polydispersity of the nanocapsules were measured by light-scattering particle size analyzer. When the concentration of SDS were increased from 2.5wt% to 10wt%,the size decreases from 3.0.5 nm to 258.3.nm, PDI decreased from 0.210 to 0.111. As the concentration of HD increased, the size and PDI were both decreased, When reaching 10wt%,the size was 258.0 nm,PDI was 0.13.. SDS and HD play important effect in synthesis of Nanocapsules containing *** changing the surfactant and costabilizer concentration it was possible to synthesize a wide variety of nanocapsules sizes. The performance and technical parameters of nanocapsules had been researched preliminarily, which built the solid foundation for the application to the self-repairing bonding resin.

With industrial grade Al（OH）3.as raw materials, the self dispersion nanosized AlOOH crystal powder were prepared by the sol-hydrothermal method. The results of XRD and TEM show that the nanosized AlOOH could automatically disperse to a single-dispersing state in water without surface modification, dispersant, additive and accessional conditions （ultrasonic wave dispersing, ball-mill dispersing）. The application results of the product indicate that the nanosized AlOOH can be composed into a toughened nanocomposites without surface modification. Accordingly, the self dispersion characteristic and mechanism of hydrothermal crystallization and charging composite dispersion of nanosized AIOOH are found, and a new technique of preparing polymer/inorganic nanocomposites is proposed, which is called blending compositing new techniques of sol even dispersing at auasi-homogeneous phase.
