Optical Density or commonly called ink density is a value of optical density in printed materials as a form of ink interaction with printing materials, especially paper.
High opacity in coated paper is achieved through materials that enhance light scattering, such as precipitated calcium carbonate (PCC) and titanium dioxide.
The CIE Lab color space* is used to describe the color of printed materials in three dimensions.

Coke is the unique role of supporting material column in blast furnace high temperature region.
After exceeding certain limits, coke will rupture badly, sizes become smaller, which makes the material column air permeability deterioration[4], blast furnace direct motion will be compromised finally.
This is the main reason that coke can support the charge as the best material for blast furnace.
The unique role of coke is to support material column in high temperature region, so the most important nature is the high temperature compressive strength after reaction.

The values of Jc and Jt of (n)GaN/(p)4H-SiC, (n)GaN/(p)6H-SiC diodes are higher than those of (n)4H-SiC/(p)GaN, (n)6H-SiC/(p)GaN devices respectively, which is due to much wider avalanche zones of the formers, although the values of GAmax, GAn, GAp of materials in the formers close to those of the latters showed in table 2 and figure 1(b).

For crankshaft main bearing abnormal sound, it is mainly due to oversize of tolerance clearance between crankshaft main bearing and its journal where the oversize is led by excessive wear between them.
It worked as follows: The materials under test were transformed into atomic vapor under high temperature; hollow cathode lamp made of the same elements radiated certain wavelength of characteristic radiation, after heated up by graphite oven, some of the radiations were absorbed by ground state atom.
Experimental part 1.1 Instruments: FAS 240 atomic absorbance spectrometry (Varian Inc, America); Copper (Cu), and Lead (Pb) hollow cathode lamps (Hitachi Inc, Japan). 1.2 Reagents and Materials: Cu and Pb standard solution, National Research Center for Certified Reference Material (NRCCRMS); Nitric Acid: Guaranteed reagent GR; Tween 80 is analytically reagent AR; Water is ultrapure water.
Subsequently, the engine demolition showed that the tolerance clearance was too large between crankshaft main bearing and its journal.

Several surveys have indicated an increase in the frequency of accidents in the transportation of hazardous materials.
When dangerous goods, such as flammable liquids, radioactive material or chemical waste are transported by ship, safety and security are matters of fundamental importance.
Extra caution against fire must be taken in the engine room, where the temperature is high and inflammable materials abound.
