In this paper, an idea is presented about a larger pressure of percolation flow existed in a part of rock by a high-pressure jet, and the pressure has great effect on the rock fragmentation with jet. A model of calculating the pressure is established.

本文提出了射流作用下岩石局部范围具有较高渗流压力的思想，并认为该渗流压力大小对射流破岩有重要影响，建立了该渗流压力的计算模型。

The numerical results of water jet breaking rock agree with the experimental conclusion. A valid approach to the process of water jet breaking rock sh...

数值计算的结果较真实地反映了水射流破岩过程中岩石的动态响应以及水射流动力学特性的演化过程，并与相关试验规律吻合良好，这表明该分析方法是有效的，可用来指导高压水射流破岩理论的进一步研究及应用。

The high-pressure jet is applied widely to the fragmentation of the rock in drilling engineering, but the mechanism of rock fragmentation with jet is not very clear by now.

高压射流辅助破岩在油气井钻井工程中得到广泛应用，其破岩机理还很不明了。

The rock damage model and the damage-coupling model suited to analyze the whole process of water jet breaking rock were established with continuum damage mechanics and micro damage mechanics.

运用连续损伤力学和细观损伤力学理论，建立了适用于水射流破岩全过程分析的岩石损伤模型以及宏细观损伤的耦合模式。

The influences of nozzle structural parameters、standoff distance and jet pressure on rock erosion effect were researched by rock breaking experiment.

该文实验研究了叶轮中心孔直径、混合段长度、扩展腔扩展角、喷距和压力5 个主要参数对直旋混合射流破岩效果的影响规律。

Just as Liam Gallagher remarked that BRMC deserved their early Oasis support slots because they 'dared to look like a rock'n'roll band' so Jet see rock music with a clarity only available to those who grew up five thousand miles away in Australia.

正如Liam Gallagher评论BRMC乐队是值得他们Oasis支持的，因为他们是真正看起来象支摇滚乐队。所以Jet对于摇滚乐有着清醒的认识。在澳大利亚，他们只接受那些5000英里远来的人的采访。

The advantage of the swirling water jet breaking rock is the heavy breaking efficiency, large breaking area and less energy used to break rock per unite volume, so the swirling water jet can drill in a hole of a large diameter.

旋转射流破岩的优势在于破碎面积大、效率高、破岩比能低，因而旋转水射流能够钻出大直径的岩石孔眼。

Vishnu entered a dark fourth dimensional dream that did not support his field or continued life.

毗瑟挐进入了一个第四密度的黑暗梦想，那里并不支持他的能量场或继续生命。
