The radiation shielding properties of materials are reported with the mass attenuation coefficient parameter.
The radiation shielding properties of the material depend on the type of radiation itself, the physical of the material, thickness and partial interactions of that material.
In most cases, high-density materials are more effective than low-density alternatives for blocking or reducing the intensity of radiation.
It has radiation protection similar to lead shielding, while being lightweight, transportable, permitting safe viewing and price competitive with other shielding materials.

Generally the microporosity is necessary to achieve excellent osteoinductivity for the MCP materials and also promoted the material resorption and bone substitute in vivo [7].
This MCP believe will prove to be promising for bone repair materials.

Screw press has been used in oil extraction with a long history, both for cold and hot pressing of vegetable oil materials.
In the squeezing chamber, the pressing screw roller is a key working part, it will push and extrude the oil materials while working, leading to the volume change in the chamber and the increase of extrusion force, thus squeezing oil from materials [7].
The pressing screw roller is an assembly part, of which the pressing screw is the most essential element, working under the condition of the friction force from oil materials and various kinds of resistance forces, with its surface wear and screw tooth fracture as the main failure forms [6,7].
It can be solved effectively by optimizing structure design, choosing different materials, improving processing methods or using different heat treatment methods, thus making the whole system more secure and reliable. 2.
