冲蚀

Effect of silicon dioxide and alumina filler with different contents on the wear-resistance properties of polyurethane elastomer was studied.

研究了不同质量分数的白碳黑与Al2O3填料对聚氨酯弹性体耐冲蚀磨损性能的影响。

The stress states of the ceramic nozzles with different entrance angle in the sand blasting process are analyzed with finite element method .

运用有限元法分析了不同入口锥角的陶瓷喷砂嘴冲蚀过程中的应力状态。

Memories are like stones, time and distance erode them like acid.

记忆中的东西就像岩石，时间和距离像酸一样冲蚀它们。

Erosion is the work of wind, water and time.

冲蚀是风，水和时间所造成的结果

About 12,300 years ago, the water plunged over the edge of the Niagara Escarpment, a cliff at what is now Lewiston, New York. The force of the water wore away the rock layers, eventually reaching its present location.

大约在1.23万年以前，大量的水涌入到尼亚加拉悬崖的边缘地区，这座悬崖就座落于现在的纽约州刘易斯顿市，水流的强大力量冲蚀着岩石层，最终形成了今天的形状。

For high-speed flow of medium, the gate to open in local conditions can cause the vibration of the gate, and the vibration may damage the gate and the valve seat sealing surface, and cutting medium will suffer erosion flashboard.

对于高速流动的介质，闸板在局部开启状况下可以引起闸门的振动，而振动又可能损伤闸板和阀座的密封面，而节流会使闸板遭受介质的冲蚀。

Some innovative approaches were presented to resolve the problem existing in the first generation of boost compressor by increasing the flow area of fluidics nozzle to decrease pressure drop and erosion attack, adding a new flow path in order to improve boosting effect of the second piston bore, connecting a bypass valve in parallel with throttle valve to set a partial flow and regulate pressure drop.

针对第一代样机存在的问题，提出了改进措施：①增加射流元件喷嘴过流面积来降低压耗和冲蚀破坏；②在射流元件输出道与二级活塞缸之间增加新流道，提高二级活塞缸增压效果；③在节流阀位置并联旁通阀进行分流稳压。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

综合岩相观察结果，建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式；其中，基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积，以及块状冷泉碳酸盐岩的出露，可能均为区域地质构造活动时期所造成；至於与含化石泥岩同时沉积的砾岩相，可能均为基底泥岩在快速浅化的过程中所沉积，标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

Time and weather have worn off the name on the gravestone.

天长日久的风雨冲蚀了墓碑上的名字。

The running water from the mountain top eroded a gulley along the slope.

从山顶上流下的水在山坡上冲蚀出一条沟渠。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
