The study confirms the coordinates measurement for gear profile and longitudinal and the absolute measurement for pitch on the base of the new type complete loop-locked CNC form gear grinding machine YK73125 and the working principle of side-type tester.

本研究以新型全闭环数控成形砂轮磨齿机YK73125为基础，依据旁置式仪器的工作原理，确定了齿轮的齿形、齿向的坐标测量法及周节的绝对测量法，并在此基础上开发了专用的随机测量系统。

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。
