因而控制送粉量的稳定性、连续性极其重要。

So it's important in controlling the powder delivery amount.

采用激光堆焊技术及自动送粉工艺进行了轴件修复实验。

In this paper we tried to repair the abraded shafts using laser overlaying welding technology.

显然这是很有实际意义的，因为同轴送粉比预置粉末更易于实现自动化和大面积激光熔覆。

Obviously, this is very significant because the coaxial powder feeding laser cladding is easy to realize automation and big area cladding.
