A number of petroleum products as raw materials such as naphthalene dispersant of coal-water slurry（CWS）[1-3] will face a shortage of raw materials.
Therefore, developing renewable resources as raw materials of CWS dispersants have been profound.
This dispersant have wide source of raw materials, low cost, good performance, and would be use widely.

As an alternative to these methods, recent proposals have emerged on the use of modern lightweight high-strength materials to reinforce reinforced concrete constructions.
The main difficulty is the different deformability of these materials.

With the productivity of β-magnetic chitosan microspheres is above 50%, the magnetic Fe3O4/βCS/HA composite microspheres are expected to become promising multi-functional bone repair materials.
Ltd., Pujiang County, China. βCS made from the skin of maggot has higher viscosity, better activity and lower heavy metal concentration in comparison to that made from shrimp shell and crab shell, so it can be used for material for skeleton repair.
Magnetic composite material is prepared by in situ precipitation method whose matrix is HA and padding is Fe3O4/βCS.

Experimental Materials.
The test materials generated one-shot molding.
After curing time 12 hours at 70 centigrade the test materials were got.
The materials time spectra were tested under cyclic loading at constant temperature.
Considering the materials underwater endures water pressure continually, the test materials were imposed a 5N static stress keeping pressure state.
