Along with the advance of economy and marketization of books and owing to the vicious competition, numerous bookshops and book merchants spring up, some of whom try to gain orders from library by great amount of commission while sell pirated books from informal channels as qualified ones from formal channels, which greatly influences the quality of books and materials and the rate of collections booking.

The ink thickness and saturation experiments were tested in printing materials lab which is the Beijing key laboratory of packaging and printing technologies and belongs to China Academy of Printing Technology.
Summary This paper based on the ink thickness experiments, try to use complex spectrum chroma to analysis the experimental data, and the conclusion is consistent with the conclusions of the CIE color science.

Step 6: Remove the photo resist on the substrate, and using screen printing method to put plastic or polymer material around the accelerometer as dam bar, then put the cap on the dam bar for curing, before sealing it one can fill it with carbon dioxide or Xe gas.
This is a new idea to use plastic material as substrate, the thermal isolation capability is better than the traditional silicon, thus the power dissipation and cost is lower for the new design. 3.

Because model is axis symmetrical, 1/4 model is taken when modeling for minishing calculate work, which is shown as Figure 2. 1-hull 2-explosive 3-combined cover 4-air 5-water Fig 2 Sketch map of simulation model In model, the material of explosive is B explosive, that of combined cover is copper, that of shell is steel. [4] 2.2　Gridding plotting Explosive, cover, shell, water and air are plotting gridding respectively by using SOLID164 hexahedron cell in ANSYS LS-DYNA.
（4）Johnson-Cook construct equation is used to describe cover and shell, the formula is shown as follow: (5) Among them, is stress of material；A, B, C, N, l, m is materail constant；is effective elasticity strain. 2.4 Calculation result According to the foregoing defined physical model and gridding plotting, the simulation results of this model are got by ANSYS LS-DYNA, which are shown as Figure 3 and Figure 4.
