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) 公式では, P—- carton compressive strength, N W—- Carton weight after loading, N N —- Number of stacking layers K—- [...]

色の基礎知識 — ラボ, Lchカラー3次元空間

1.1. The definition of “L, A, NS”During 1950s and 1960s, Hunter Lab established color space, which was represented by THREE-DIMENSIONAL coordinates of L, A and B The “L” represents the brightness of the object: 0-100 represents the range from black to white “A” represents the object’s red-green color: positive values represent red, and negative values represent green “NS” represents the object’s yellow and blue color: positive values represent yellow, and negative values represent blue 1.2.Establish the meaning of “L A B” color space The [...]

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.の:8 Diffuse illumination, 8° receiving, including specular reflection component.The sample [...]
