摘要：
An experimental model for electronic chip cooling was designed to investigate the cooling performances of an air-cooled thermoelectric cooler (TEC). The effect on the cold side temperature was experimented on the variation of heat emission intensity of TEC hot side and operating current. It was found that the mean temperature of the TEC cold side will decrease with enhanced the fan power, and the cooling performance would be better. The cold side temperature of TEC appeared a low valley with operating current variation. Optimizing the heat emission and the operating current properly is necessary to make the TEC work at perfect cooling performance.
摘要：
In this paper, modal characteristics of self-compacting concrete (SCC) beams were studied through experiment. 3 self-compacting concrete beams were gradually damaged and then subjected to vibration test in free-free boundary conditions after each load step. From analysis, eigenfrequencies could indicate the existence of damage but it could not represent the damage locations. Modal Assurance Criterion (MAC) is lesser reliable to indicate crack damage compare to eigenfrequencies. Next to these, capacity for damage detection and localization of Coordinate Modal Assurance Criterion (COMAC) and the flexibility matrix method are also examined and compared. This paper introduces in detail the dynamic properties and damage localization methods in SCC, which provide basal databases of damage diagnosis for SCC structures and promote the popularization of SCC in civil infrastructures.

摘要：
3-D dynamical response analysis of concrete-faced rockfill dam is presented. Using equivalent-linear model, based on different dam heights and different shapes of river valley, the responses of dam subjected to different seismic intensity inputs have been studied. Especially the systematic analysis about the influence of the valley width on the distribution of the acceleration at the central points the bank slope is conducted. The results show that, the distribution of the horizontal acceleration along the dam heights at the central points on the central section of concrete-faced rockfill dam performs that the acceleration magnification which increases remarkably over 0.8H is a little smaller during 0 similar to 0.8H. For high concrete-faced rockfill dam, with the base acceleration excitations unchanged and the bank slope becoming steep (a gradient of 0.4), the valley width has a great impact on the magnification of the horizontal acceleration. The narrower the river valley is, the bigger the acceleration magnification is. With the slowing of the valley slope, the distribution of the acceleration magnification remains unchanged but the maximum reduces a little.

The results show that, the distribution of the horizontal acceleration along the dam heights at the central points on the central section of concrete-faced rockfill dam performs that the acceleration magnification which increases remarkably over 0.8H is a little smaller during 0~0.8H. For high concrete-faced rockfill dam, with the base acceleration excitations unchanged and the bank slope becoming gentle, the maximum acceleration on the top of the dam reduces. Under various seismic intensities, for non-high dams in the broad river valley the slope has almost no impact on the magnification of the horizontal acceleration.

摘要：
With the example of the water supply engineering planning of small towns in southern china, the effects of town water consumption forecast, water resource selection, water site choice, pipe network planning on the present engineering planning of water supply were investigated. The analyses show that the water consumption forecast should adopt many kinds of methods to check each other, and finally determine a proper value. To ensure water yield of source water reliable and water quality to meet the requirements are the first principle of the water resource selection. The location of water plant should be determined according to the characteristics of the water source and the hydrological and hydrogeological conditions, in accordance with the relevant requirements specification. The basic requirements of the pipe network layout are as follows: the security of water quality; the reliability of the water volume and water pressure; the operation reliability and the least investment. As a part of the overall planning, the water supply engineering planning should proceed from reality to deal with the relationship of the recent construction and long-term development in order to push small towns economy to a rapid growth.

摘要：
Soil around the cylindrical pore is divided into elastic and plastic regions. In the elastic region, the small deformation theory is applied while in the plastic region, the large deformation theory and unified strength criterion are applied. According to the stress equilibrium equation and the boundary condition of continuous stress and deformation, the theoretical solution to plastic region radius, limit expansion pore pressure excess pore pressure and excess pore water pressure of the cylindrical cavity expansion can be derived when considering large deformation and non-drainage problems. Compared to the theoretical results of Cao L.F., the theoretical calculation results are closer to the field test results which show that the theory has a certain value in engineering application. Through calculations and analysis, it is also derived that expansion pore pressure increase is non-linear with the increase of b value, while the excess pore water pressure is just the opposite.
