The objective function of model is to minimize time delay meeting material need, and the constraints include vehicle balance constraints, traffic constraints, road capacity constraints, constraints of rescue materials supply point, demand constraints, and so on.
Therefore, the determination of temporary rescue path , rush repair and arrangement of damaged transportation routes and the facilities, timely rescue and transfer of afflicted personnel, timely allocation and service of disaster relief personnel, layout optimization of emergency logistics facilities, reserves control of emergency rescue materials, optimization scheduling of emergency rescue materials, and collaboration transportation plans of various transportation way are the eight key problems in optimization of emergency transportation and logistics system, and they are interdependence and interaction.

Nano CT with synchrotron radiation has a high spatial resolution up to nano scale which provides an approach to the 3D inter-structure of sample of tiny size in the research of biology, materials and so on.
All the outstanding aspect of this technique shows its great potential in the study of life science, biological science, materials science and environment science [1-3].
So this proposed method has great potential applications in nano CT for life science, material science and many other research fields.

It was found that the Mott-Grady theory provides reasonably good predictions of the fragment sizes for ductile materials.
Introduction Materials usually break into many fragments under very high strain-rate loadings.
With this method, Hoggatt and Recht[2] obtained the dynamic uniaxial tensile stress-strain data for several ductile materials.
The Mott-Grady theory can provide reasonably close predictions of the fragment size for the ductile materials being tested.
