WR nebula,Wolf-Rayet nebula是什么意思

用法例句

The concentration distribution of particles in 90°horizontal bending pipe of WR burner was measured under different conditions with the use of 3 dimensions particles dynamic analytical apparatus(3D-PDA).

利用三维粒子动态分析仪(3D-PDA)在不同工况下对颗粒在WR燃烧器水平90°弯曲圆管内的浓度分布进行测量,同时测定不同工况下的阻力特性,得到较佳的滑块尺寸,并对影响这种弯曲圆管浓淡分离的因素进行理论分析。
