This has not only brought great harm to port safety and caused environmental risks, but also increased difficult of rescue for water chemistry accidents.
The ship's structure, equipment, layout, cargo stowage, segregation and other projects targeted on on-site supervision and inspection will be covered.
Avoid risks by emergency plans In accordance with legislative requirements, it is necessary to establish water chemistry relief organizations at different levels, ie., the national professional organization, the regional organization, and the organizations of individual business operators so as to deal with issues of compensation mechanism, fund establishment, emergency response center and the likes.

When the temperature was raised at 650 0C, it can be observed that almost diffraction peaks were assigned as the hexagonal LN structure with some peaks of cubic LiF as impurity.
That result meaned that excellent composition of chemistry of LN powders when calcination temperature was at 650 0C.
The excellent composition of chemistry of LN powders were obtained when the calcination temperature was at 650 0C.

But because of its smooth surface, smaller friction coefficient, closed fiber structure, poor adhesion, poor hygroscopicity, and the lack of polar and functional groups, its use in complex with other materials and filter material is limited.
（a）untreated (b) treated by the plasma(20Pa ,200W,300S) Fig.1 Surface morphology of PPS fiber (amplify 5000 times) XPS analysis The low temperature plasma modification not only caused the change of surface morphology, but also it made the chemistry composition change on the surface of fiber.
