According to the feature of SLS, the parameters of interest are layer thickness, hatch spacing, laser power, scan speed, work surroundings temperature, interval time and scanning mode.
根据SLS加工工艺的特点，研究的工艺参数包括：层厚、扫描间距、激光功率、扫描速度、环境温度、层与层之间的加工时间间隔和扫描方式。
The layer with the largest spacing to one of its neighbours also possesses the maximum surface atomic density.
面间距最大的一对原子面也具有最大的面原子密度。
With decreasing the film thickness, both the dislocation spacing and the ratio of the dead layer to film total thickness increase.
随着薄膜厚度的减小，位错间距增大，“死层”厚度与薄膜总厚度之比增加。
