How to calculate the compressive strength of cartons?

Cartons are required to have a certain compressive strength, because after packing goods in the process of storage and transportation, the cartons stacked in the lower layer are under the pressure of the upper cartons. In order to avoid collapse, they must have appropriate compressive strength. The compressive strength of cartons is calculated by the following formula: P = KW (n – 1) 공식에서, NS—- carton compressive strength, N W—- Carton weight after loading, N N —- Number of stacking layers K—- [...]

Knowledge of colour measurement – about the illumination and observation geometry of chromatic aberration instruments

Knowledge of colour measurement About the illumination and observation geometry of chromatic aberration instrumentsThe human eye cannot quantify color correctly, but we can use chromatic aberration instruments and spectrometers to measure color, which is quite simple.And the position relation among the lighting source, the measured sample and the sensor is the illumination observation geometric condition in the color measurement, referred to as geometric condition.Cie15:2004 recommends ten types of reflective sample measurement geometry:1.di:8 Diffuse illumination, 8° receiving, including specular reflection component.The sample [...]
