实验结果表明：在超临界压力区域，倾斜光管内可能由于受到热加速度和浮力的综合作用，倾斜光管传热特性沿周向是不均匀分布状态，通常管内顶部的壁面温度比底部高，在大比热区发生传热恶化和传热强化的现象，低质量流速和高热负荷条件下会发生传热恶化现象，高质量流速下会发生传热强化，避免壁温发生飞升；内螺纹管内的传热特性在不同焓值区域表现不同，在远离拟临界焓值的低焓值区域和高焓值区域，呈现出相似的规律，而在接近拟临界焓值区域时，传热得到强化。

By using grand canonical ensemble Monte Carlo method, machanism for the adsorption of methane in single wall carbon nanotubes at 74.05 K has been investigated. It is found that the adsorption of methane in smaller SWNTs, whose diameters are 1.22nm and 1.632nm, exhibits "pore filling" behavior. In contrast, for the SWNTs of diameter larger than 2.04nm, capillary condesation takes place.

The central angle of the impingement fluid separated from the target surface became larger with the increase of jet Reynolds. And the separating angle also increased with the increasing ratio of the jet distance to the diameter of the jet hole, while the range of induced vortex became smaller.

试验中发现随着冲击雷诺数的增加，冲击气流与壁面分离处对应的圆心角增大，分离推迟；随着相对冲击间距值的增加，气流与壁面分离处对应的圆心角越来越大，相对于受限空间的大小，诱导涡的范围越来越小。

Such observation resulted from the special shape of the conical column, in which the composition of forces near the conical column wall was different from that near the cylindrical column wall owing to the existence of the inclined plane.

这是由台锥形柱特殊的结构造成的。由于台锥形柱斜面的存在使流体在管壁区的受力情况不同于圆柱的管壁区

It was shown that 1%Eu-PZT films have the highest Rayleigh constant, which indicates the minimal interaction of defect-domain walls and high contributions to dielectric and polarization. The high mobility of domain walls, combined with the obvious improved crystallization of 1%Eu-PZT results in the increase of dielectric constant and remanent polarization.

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.
