捻发音的

Diffuse crepitus of the arm, extending to the left chest wall, was noted.

弥漫性的捻发音从胳膊延伸至左侧胸壁。

Many people have some degree of crepitus, a crackling or grinding sound made when uneven cartilage surfaces rub against each other. It usually occurs in large joints, like the knee or shoulder.

很多人都有不同程度的捻发音，凹凸不平的软骨组织表面互相摩擦的时候会发出的一种噼啪声或者研磨声，通常发生在膝盖或者肩膀这样的大关节。

Crepitus is different from the loud snap you hear when you crack a knuckle: That's caused by nitrogen bubbles inside the joints popping under pressure, says Raymond Rocco Monto, M.D., an orthopedic surgeon and spokesman for the American Academy of Orthopaedic Surgeons.

矫形外科医生，同时也是美国骨科医学院的发言人，雷蒙德·洛克·蒙托医学博士指出，捻发音和你猛按指关节时发出的脆响有所不同：后者是由关节中的氮气泡在压力下破裂造成的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
