The surface and cross-section of the pock flaws which appeared on the hot-dip galvanized coating were observed and analyzed by using SEM and energy spectroscopy.
通过扫描电子显微镜对热镀锌钢板镀层表面麻点缺陷的表面和断面形貌进行了观察，并对其进行了能谱分析。
Therefore, selecting the water temperature properly the hot water processing of big cross section machine parts of 45 steel can replace modified treatment.
这样，适当选择水温，45钢制较大截面工件的热水处理可代调质处理。
Cold-formed steel cross section on the residual stress distribution is curved, and hot rolling steel or steel section on welding residual stress distribution is a thin film type.
冷弯薄壁型钢截面上的残余应力分布是弯曲型的，而热扎型钢或焊接型钢截面上残余应力分布是薄膜型。
While vortex in the cross-section promotes the mixing of cold and hot air near the wall with an enhancement in heat transfer.
而横向截面的涡团则促进冷气与壁面热气的掺混，提升了换热效果。
