声学.施工现场路面对噪声吸收性能的测量.扩大表面法 - Acoustics - measurement of sound absorption properties of road surfaces in situ - part 1 : extended surface method iso 13472 - 1 : 2002
声学.现场路面吸声特性的测量.第1部分:扩展表面法 - The effects of various structure parameters and fins arrangement of the three dimensional extended surface on heat transfer performance in the 3 - d ift have not been studied systematically
特别是在三维内肋管肋形结构尺寸，肋排列形式等影响管内对流换热特性因素的系统研究工作还有待于进一步的完善。 - Compares the 3 - d ift with smooth tube , the result shows that heat transfer augments , volume decreases , metallic material reduces and energy saves . so the tube with three dimensional internally extended surface have very wide engineering application background
使用结果表明：使用了三维内肋管的换热器同未使用前相比，换热强度提高，体积减少，金属材料耗量减小，能耗降低，具有十分广阔的应用前景。 - Abstract : in this article , the optimization of surface crack detection of speed reducer gear was made using fuzzy set theory , the result show that the rotation magnetic field is the best way of surface crack detection and lots of extending surface fatigue cracks were found in practice
文摘:采用模糊集的贴近度计算对齿轮表面探伤方法进行了优化选择，表明旋转磁场探伤是齿轮表面探伤的最佳方法，在实用中检测出大量的正在延伸扩展的表面疲劳裂纹。
