黄铜的

I picked some different sizes of aerofoil tube at the hobby store today when getting more brass rod and tube.

我挑选了一些不同规模的翼型管在嗜好商店今天，当越来越黄铜棒和管。

Additionally, I have decided to manufacture two (2) more brass tubing guides; forward and aft.

此外，我已决定制造2（ 2 ）更多的黄铜油管指南；弘扬和尾部。

The wear debris of three semi-metallic friction materials reinforced by low carbon steel fiber, brass fiber and pure copper fiber respectively, and grey cast iron couple woren at different temperatures were studied by XRD and EDAX. Wear properties were analyzed together with the surface images got by scanning electron microscope.

摘 要：采用X射线衍射和X射线能谱分析对分别使用低炭钢纤维、黄铜纤维和紫铜纤维增强的3种半金属摩擦材料与灰铸铁在不同温度下滑动摩擦形成的磨屑进行分析，并结合扫描电子显微镜观察摩擦材料表面形貌，分析材料的磨损特性，并对黄铜纤维和紫铜纤维增强的摩擦材料磨屑成分进行对比分析。

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。
