Crack reasons for this are: the heating temperature is too high as a result of quenching or cooling in a hurry, the quality of thermal stress and metal volume changes in the organization of the anti-stress than the breaking strength of steel; the work of the original surface defects (such as surface micro-cracks or scratches) or the internal defect of steel (such as slag, serious non-metallic inclusions, white point, the residual cavity, etc.) formed in the quenching stress concentration; serious Decarburization and carbide surface segregation; parts after quenching Back lack of timely or tempering fire; processes in front of the stress caused by excessive cold red, forging folding, turning deep marks, sharp edges and corners, such as the oil groove.

造成这种裂纹的原因有：由于淬火加热温度过高或冷却太急，热应力和金属质量体积变化时的组织应力大于钢材的抗断裂强度；工作表面的原有缺陷或是钢材内部缺陷（如夹渣、严重的非金属夹杂物、白点、缩孔残余等）在淬火时形成应力集中；严重的表面脱碳和碳化物偏析；零件淬火后回火不足或未及时回火；前面工序造成的冷冲应力过大、锻造折叠、深的车削刀痕、油沟尖锐棱角等。

The results indicated that most students were dependent on the problem's surface structure for their sortings. Futhermore, an interaction effect was found between the student's grade and their achievement. As the grade level increase, instesad of using surface structure, high achievement students tended to sort problems according to their semantic structure. On the contrary, low achievement students became relied more and more on the surface structure of the problems while sorting.

另外，学童之年级及其数学成就对他们采用何种策略解题有交互影响；随年级的提升，高数学成就组学童倾向放弃弃表面特徵，而改较高层次的语意结构作为分类的基础；反之，五年级低成就组学童则变得更依赖问题的表面特徵作为分类的依据。

The results show that, the chloride concentrations and diffusion coefficients are both a one-humped function of elevations (can also be the time scale of seawater infiltration), they increase with the increase of elevation until they get to the peak value, and then decrease with the increase of elevation; an evident relationship is being between the surface chloride concentrations and the wave forces acted on the concrete surface, while there is no much difference among the diffusion coefficients; the diffusion coefficients get to bigger as the depth from the concrete surface increase in the influence of the capillary structures evolution and chloride concentration, but this tendency of change was alleviated with the increase of depth.

研究结果表明：氯离子侵蚀混凝土设施的竖向分布规律为氯离子浓度、扩散系数与标高之间同为单峰函数分布，先随高程变大而变大，达到峰值后，随高程变大而减小；氯离子侵蚀混凝土设施的环向分布规律为混凝土构件表面氯离子浓度、氯离子通量与波浪力之间有明显的对应关系，波浪力越大，则表面氯离子浓度和氯离子通量越高，而扩散系数在各方位角差别不明显；由于混凝土长期服役过程中内部毛细孔隙结构演化以及氯离子浓度的影响，氯离子扩散系数随混凝土深度变大而变大，但这种变化趋势随深度逐渐趋缓。

Firstly, the mechanism of heat transfer enhancement by oscillation heat surface is discussed in natural convection scene. For different oscillation amplitude and Rayleigh number, the frequency that the heat transfer rate of oscillation heat surface is higher than non-oscillation condition is found and called critical oscillation frequency. The limitation enhancement of similar physical model is still researched by this study in mixed and forced convection scenes for different amplitude and Grashof number. Generally, that a heat surface subject to a oscillation motion is advantageous to convective heat transfer is a well-known tuition.
