The paper investigated NO. 6308 bearing in the areas of manufacturing, measuring, selective assembly and quality control. It put forward the concept of upgrade.

For the company adopting the selective assembly method, design and control of the production system will have an impact on the deployment of the resources, operation efficiency and the total revenue.

From behavior of block copolymers in selective solvent, we knew that self-assembly of supramolecular was influenced by kind and concentration of solvent.
