Rare Metals 2013年第5期32卷 532-536页

The technology that silicic acid was pressurized under high temperature in order to dehydrate and transform was investigated in the paper. The effects, such as the ratio of liquid to solid, pressure, temperature, and reaction time on the dehydration rate and volume shrinkage rate, were researched. The experimental results show that the dehy- dration rate of silicic acid is up to 41.20 %, accompanying with the volume shrinkage rate of 40.37 % after silicic acid is pressurized under high temperature in the high-pressure kettle. The results of silicic acid tested by SEM indicate that the metasilicate acid molecules and water molecules are closely arranged, and there.are.almost no gaps before pressure reaction. There.are many gaps accompanying with formatting lamellar structure.after pressure reaction. The experimental results indicate the effect that silicic acid is dehydrated and transformation is obvious under high temperature.and pressure.

A bandpass negative group delay(NGD)passive circuit based on defect ground structure(DGS)and substrate integrated waveguide(SIW)-matched is developed in the paper. The NGD DGS topology is originally built with notched cells associated with self-matched substrate waveguide elements. The DGS design method is introduced as a function of the geometrical notched and SIW via elements. Then, parametric analyses based on full wave 3-D electromagnetic S-parameter simulations were considered to investigate the influence of DGS physical size effects. The design method feasibility study is validated with fully distributed microstrip circuit prototype. Significant bandpass NGD function performances were validated with 3-D simulations and measurements with-1.69 ns negative group delay value around 2 GHz center frequency over 33.7 MHz NGD bandwidth. Insertion loss is 4.37 d B, and reflection loss reaches 41.5 d B.

Dams and Floods

Engineering 2017年第1期3卷 144-149页

作者： F. Lempérière HydroCoop Paris 92190 France

The possible mitigation of floods by dams and the risk to dams from floods are key problems. The People's republic of China is now leading world dam construction with great success and efficiency. This paper is devoted to relevant experiences from other countries, with a particular focus on lessons from accidents over the past two centuries and on new solutions. Accidents from floods are.analyzed according to the dam's height, storage, dam material, and spillway data. Most of the huge accidents that have been reported occurred for embankments storing over 10 hm3. new solutions appear promising for both dam safety and flood mitigation.

Gate Oxide Short (GOS) defects are becoming predominant as technology is scaling down. Boolean and IDDQ testing of this defect has been widely studied but there is no paper dedicated to delay testing of this defect. So, this paper studies the delay behavior of Gate Oxide Short faults due to pinhole in the gate oxide. The objective of this paper is to give a detailed analysis of the behavior of the GOS defect taking into account the random parameter of the defect such as the GOS resistance and the GOS location. Because an accurate analysis is desired, the bi-dimensional array will be *** a complete analysis is desired, we derive the dynamic characteristic of the GOS as a function of the GOS resistance and location. It is demonstrated that i) GOS has a significant impact on gate delay, ii) GOS located close to the source of the transistor and with small resistance has very high impact.

The formation and the thermal stability of a connected hard skeleton structure(CHSS) in the matrix of Mg-5Al-2Sn-5Ca(ATX525) alloy were investigated by using X-ray diffractometer, scanning electron microscopy, differential scanning calorimeter, creep tester and isothermal treatment method. The results indicated that the CHSS composed of Mg2(Al,Ca) and Al2 Ca intermetallics was formed into a typical eutectic structure.and no obvious change occurred when the samples were isothermally treated at 250 °C for 96 h and 350 °C for 72 h, respectively. It became a chained structure when isothermally treated at 450 °C for 48 h. The dissolution and reconstruction processes, however, were observed for the CHSS when the processing temperature was up to 550 °C. The creep life at the stress-temperature condition of 50MPa/200°C for the alloy treated at 450 °C for 48 h was as high as 510 h, and the strain at creep time of 100 h was as low as 0.03%, which indicated that the present alloy has not only a good thermal stability, but also a better heat resistance.
