This is because they used a small laser spot in the process; it was less than 500 micrometers in diameter — about half the diameter of laser spots used in traditional material deposition.
因为在沉积过程中，他们使用的是直径小于500微米的激光斑点，这大概是传统材料沉积中使用的激光斑点直径的一半左右。
The numerical model is set up on the basis of the action and mechanization generated by laser and material in laser melting process.
激光熔凝处理的数学模型是以激光与材料相互作用的过程及其此后发生的物理规律为基础建立的。
Precoated sand made of mixing this kind of resin and sand can serve as laser sintering material which suits laser rapid molding process much more.
这种烧结剂是一种改性酚醛树脂，它和作为耐火骨料的原砂混合制成覆膜砂作为激光烧结材料更加适用于激光快速成型过程。
The laser welding is a fast and uneven heat cyclical process. Because of complexity of the interactive between laser and material, it is very difficult to guarantee the quality of the laser welding.
激光焊接过程是一个快速不均匀的热传导过程，由于激光与材料相互作用的复杂性，使得激光焊接质量难以保证。
