In order to protect sensitive information of the nuclear materials recognition system from leaking, this article combined with the functional requirements of information barriers and design elements, designed neural network verification system solutions and hardware and software.
Its information adopts distributed memory and is not easy to be lost with the robustness[1]. 1.1 Neural network function realization and processes The classification of the type of nuclear material (parts) by the neural network is achieved through two stages: first, according to the selected sample spectroscopy data, neural network could self-learn.

If ductile cast iron is transformed to bainite single-phased structure through austempering treatment, its ductility goes down considerably compared to cast materials composed of ferrite-pearlite.
The tension and strength of each material are presented in Table 2.
In full-ADI, static strength was enhanced considerably compared to the cast material, but ductility decreased a lot.

The crystallization of amorphous alloy can make structure and properties of materials greatly changed.
Therefore, the behavior of crystallization of BMGs is significantly important to determine the forming ability of BMGs and prepare the new materials [10].
XRD pattern of bulk Zr70Cu8Ti7Ni15 metallic glass in as-cast state As shown in Fig. 1, this alloy has the typical characteristic of amorphous materials.
