Experimental results indicate that the B/A value greatly affects the internal Nusselt number and friction factor of the twisted tube because the parameters decrease with the increase of B/A and S/d values, more rapidly with the former, and that the Nusselt number and friction factor of the twisted oblate tube increase respectively by 30%~150% and 20%~50%, as compared with those of the smooth tube at the same Reynolds number and Prandtl number.
实验结果表明:高扭曲比螺旋扁管的管内努塞尔数和阻力系数均随B/A值和S/d值的增大而减小,但随B/A值的增加而减小得更快,B/A值对高扭曲比螺旋扁管的管内传热与流阻性能影响更大;在相同雷诺数和普朗特数下,高扭曲比螺旋扁管管内的努塞尔数为光滑管的1.3~2.5倍;阻力系数为光滑管的1.2~1.5倍。

The oscillation performance of jet, as oscillation frequency, is the essential data for designing the fluidic device, which is also the key factor that influence the coupling effect of fluidic device and receiving tube. This paper does experiment on the oscillation availability and frequency of feedback jet-oscillation gas wave refrigeration. As a conclusion, the jet oscillates only in a certain range of geometrical sizes and operating conditions. Under the condition of high pressure ratio, the frequency of the jet"s oscillation is only affected by the feedback tube"s length and chamber remarkably. Under the condition of low pressure ratio, the frequency descends with rise of the pressure ratio.
本文将跨音速正反馈射流振荡器与接受管耦合,对耦合后的射流振荡气波制冷机的可振性、振荡频率以及它们的影响因素作了实验研究,得出如下结论:射流只在一定的操作条件和几何结构尺寸范围内才能稳定振荡;射流的振荡频率在较高压比下只受反馈管长和反馈管容腔大小的显著影响,在小压比下随压比的增大而增加;其它结构尺寸和操作条件只影响可振性。

The energy exchange analysis indicates that gliding energy efficiency is dependant on the lift drag ratio of the wings and gliding angle of the hull. Through the calculation in this thesis, it can be concluded that enhancing the lift drag ratio can largely improve the energy efficiency when the gliding angle is in the range of 10to 40 degree, and when lift drag ratio is fixed, there exists a special gliding angle for the maximum of the efficiency, which provide theoretical basis for the design of operating parameters.
通过能量转换分析,得出滑翔机航行效率由机翼升阻比和机身航行角决定,航行角在10~40度范围内,增大机翼升阻比可显著提高航行效率;并由计算得出,在升阻比一定的情况下,总存在一个使滑翔机航行效率达到最大的航行角度,为样机工作参数设计提供了理论依据。

Ordinarily the reaction rate of amino acids is faster than that of glycols, but the carbon chain of ethylene glycol is very short, the reaction rate of L-aspartic acid was longer than that of ethylene glycol.
另外,丁二醇比乙二醇碳链长,位阻大,反应慢;通常氨基酸的反应速度要比醇快,但由于乙二醇的碳链很短,导致其比天冬氨酸的反应速度还快。
