Swinging fast is not the important thing . even when you swing in slow motion , you ' re grooving a muscle memory that will stay with you . take your racquet with you everywhere 快速地挥拍不是重要的事物。甚至当你在慢动作中挥拍的时候，你将刻凹痕于肌肉记忆,那将与你同在。到处带著你的网拍跟著你。
The scissors shape of concavity on the wall was used to lock the beam to avoid damages from earthquakes and the square cave was dug by cing s army to put posts while constructing their barracks 城壁的上端仍留有剪刀形的壁锁凹痕，是锁梁柱用的，防地震；方形的洞口则是清军筑营房时挖的，用来放柱子。
It is effective to improve the car body shock resistance and prevent indenture which is collided by the stone when the car is running , so it prolongs the service life of a car 采用高强度钢板还可以有效地提高汽车车身的抗冲击性能，防止在行驶中由于路面的砂石飞溅碰撞产生凹痕，延长了汽车的使用寿命。
Lichen eats away at granite and over time can cause cracks and pockmarks . if left for long enough , they could eventually cause the 60 - foot tall （ 18 meter ） statue to crumble 苔藓会侵蚀花岗岩，而且随着时间的推移，这些苔藓会使岩石产生裂缝和凹痕。如果长时间不加清理的话，它们最终会把这座高60英尺（约合18米）的宏伟雕像变成碎片。
4 . the principle of the experiment including the isdg method is introduced . and the effect of shape and distance of the indention on strain measurement is analyzed 4 )介绍试验设备的组成及试验原理，通过理论推导和有限元数值模拟分析了拉伸试样的凹痕标记对应变测量的影响，对isdg ( interferencestrain displacementgauge )方法进行了深入的研究。
The mainland , not so very far off - - you could see clefts in the cliffs , white cottages , smoke going up - - wore an extraordinary look of calm , of sunny peace , as if wisdom and piety had descended upon the dwellers there 内陆，不算太远? ?竟能看到悬崖上的凹痕、白色小屋、炊烟袅袅升起? ?笼罩着一抹奇异的神色，充满沉静而阳光平和，好似智慧与虔敬降临于那里的居民。
The blue - tak tears on bedroom walls , a water - colour sun and stick man hiding behind a fitted wardrobe , a dent in a table , a crack in a mirror , were all passing moments etched into the physical world , like voices pressed into vinyl 卧室墙上的那条裂口，水彩画的太阳和藏在衣柜的握着手仗的男人，桌子上的凹痕，镜子上的裂痕，都是镶在这个有形世界里短暂的瞬间，就如声音被压缩在磁带里。
This paper analyzes the cause of small concaves around the welding seam in the long rail of guangzhou metro line 2 , and presents preventive measures , such as increasing the under layer of the rail , limiting the weld seam , lowering the welding temperature etc 摘要结合广州地铁2号线接触焊焊接长钢轨的实践，分析了产生焊头表面小凹痕的原因，提出改变垫高钢轨的方式、缩小正火范围、降低正火温度、限制接头错牙量等预防措施。
The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment , and at the same time , the gel content had extreme value with the change of the dose rate . the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment , narnely rough degree increasing . their number and deepness increased with increase of dose . and this phenomenon is the most obvious when the dose rate was 8 . 5kgy / s and the dose was 400kgy . at the same time some containing oxygen groups , including hydroxyl group , carbonyl group and carboxyl group , were introduced into the fiber surface which was exposed to the air 研究表明， uhmwpe纤维经电子束辐照处理后，纤维的拉伸断裂强度随剂量率的增加呈下降趋势，凝胶含量随着剂量率的变化存在极值。纤维表面出现了不规则的微裂纹和凹痕，随着剂量的增大，电子束对纤维表面的刻蚀程度增加，在本研究中以剂量为400kgy剂量率为8 . 5kgy s时刻蚀效应最为明显。同时，在空气中进行辐照时，纤维表面被引入了一些含氧基团，包括羟基、羰基和羧基。
