Base on the concept of image pointdiameter, formula was obtained to estimate concentration limit when particle-imaging technique was used for measuring particulate flow.
基于像点直径的概念，推导了颗粒成像法测量颗粒场时的最大极限浓度估算公式。

Point sample and solvent evaporating integration, seven channels can be automatically sampling, spot diameter less than 3 mm.
点样和溶剂挥干一体化，七通道可同时自动点样，斑点直径小于3毫米。

This function can make numerical control system according to the point in the X coordinates, as the diameter of the workpiece calculated value spindle speed, and the cutting speed to be constant.
