In the tunnel project, the main uncertainty factors with various project backgrounds include geographic size uncertainties, initial conditions uncertainties, boundary uncertainties, materials parameter uncertainties, load uncertainties and calculation model uncertainties.
The others (e.g. surrounding and lining materials parameters) have minimal impact, called non-sensitive factors.

If all of the non-value stream in drop-parts in Surface Mounted Technology (SMT), scrap material, repeatedly testing, waiting for raw material, unnecessary transporting, unnecessary stock, and every defective in usage are removed, everything is done well in the first time, then the value stream flows from raw material to customer.
The top one is related to the assembly in production line, and then PCB printing file issue, testing failure, packing failure, purchasing material and raw material issue.

These materials have the zincblende structure.
One takes a direct band material with a small energy band gap and an indirect band material to make a material that have a wide direct band gap value [16].
Such materials are important for solar cell applications.

And these element material parameters are set to the real material parameters and only their topological variables are set to ),2,1( 1 L=jt jm at the first iteration step after applying the operations of Eq. (6) .
The modified values of fjqC , qa and qb for all real material elements are substituted into Eq.(10).

Introduction Materials with a core/shell heterostructure are of particular interest because of their potential applications [1-4].
Among these structures, noble nanocables has been focused on recent years with metal core and amorphous carbon or polymer shell, which often exhibits different chemical and physical properties from those the sole core or shell materials as potential building blocks in various nanodevices.

The supply chain of large aircraft The supply chain of large aircraft includes raw material supply and parts supply.
So, engines and new materials, especially the composites, will be the largest technical barriers of large aircraft project development in China.
Science and technology affect the long-term real output, so, we must choose a longer time frame to study.
