The grain shape of Co change to equaxial fine grain and refined by adding of Al2O3 powder.

SEM的表面型态中，未添加Al2O3皆发现等轴状细晶，在添加Al2O3后，成核点数目变多，晶粒会随著添加量增加而减小。

UHMWPE has regular molecule chain and lower shear strength, so it improved the tribological property of PA66. When the amount of the transferring layer reached a certain value, severe plastic distortion and adhesion wear occurred, and wear resistance of the blends was related to the mechanical property of the blends. Worn microstructure changes with addition of compatibilizer. Soft UHMWPE produced from friction heating has low shear strength, and it improves the tribological property of PA66 during the friction course.

结果表明：加入MAH-g-HDPE相容剂可以使共混体系的相容性得到改善，提高共混物的机械性能；具有平整分子结构的UHMWPE有利于改善PA66的摩擦磨损性能，当摩擦偶件的转移层达到饱和状态后，共混物的耐磨性与其力学性能相关；共混物在摩擦过程中表现出严重的塑性变形和粘着磨损，但在共混体系的摩擦过程中，对摩擦磨损性能起主要作用的是受热软化的UHMWPE在磨损表面形成低剪切强度的界面层，从而使得PA66的摩擦磨损性能明显改善。

Reynolds number of impingement, inclined jet angle, the ratio of the jet distance to the diameter of the jet hole and the relative curvature (the ratio of the diameter of jet hole to the diameter of concave surface) were changed to study the rules of flow structures varying with these parameters. At the same time, the developing and disappearing phenomena of the induced vortex were analyzed.

通过改变冲击雷诺数、冲击角度、相对冲击间距（冲击间距和冲击孔直径之比）以及相对曲率（冲击孔直径同凹面靶板直径之比）等参数，分析了受限空间中，斜向冲击曲率表面后产生的涡系结构及其发展和变化规律。

It is revealed from the analysis that the distribution, composition, lithofacies changes, and the formation mechanism and age of the relict sand are not consistent with the present depositional environment of this area.

它是在晚大理冰期最低海面后海平面不断上升过程中不同阶段的滨海相沉积，从冰后期海平面大规模上升以来，沉积作用在这些地区是微不足道的或者竟完全缺失，从而使砂质沉积直接裸露在海底表面，未被现代沉积所覆

Remeasure and record the distance from the face of the test block to the reference point on the lever handle.

静止后，再次测量并记录治具内表面到手柄内侧距转轴50 mm 处的距离。

To improve the resistance to abrasion for surface of cast iron,the wear resistibility of grey cast iron HT200 is increased by employing inert gas tungsten arc remelt and fast solidified.

为了提高铸铁表面的耐磨性，以HT200为试验材料，用钨极氩弧对其进行了局部重熔强化的系统研究，得出了相关工艺参数对重熔处理后表层组织和性能的影响规律。

Mean epi-esophageal pressure after retractor opening was 76.3 mm Hg, and mean endo-esophageal pressure was 16.3 mm Hg.

结果：肌肉收缩后的平均食管表面压力为76.3mmHg，而平均食管内压力为16.3mmHg。

Brown rhizomorph and hyphae can be seen on the seedlings'rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.

子实体单生或丛生，出菇至成熟3 d~4 d，单个子实体重20.0 g~62.0 g；小粒咖啡苗的根茎、主根及侧根被茶褐色的菌索和菌膜包裹，而根尖及靠近根尖的侧根上没有菌丝和菌索生长或生长很少；盆栽小粒咖啡苗，在接种90 d后其根系表面的菌索死亡。

The surface temperature of the cooled rods was only 300 degrees Centigrade, there would be no danger immediately.

冷却后的燃料棒表面温度只有摄氏300度，不会有立即的危险。

These surfaces sweep along the roofline all along the upper sidewall boundary down to the back-end.
