Since the thermal conductivity is low, this method is not suitable for high-power LED drivers; b) encapsulating thermal conductive materials for the interior of the drivers' power supply.
The shrinkage of thermal conductive materials will produce stress to the pins of electric components, and the power supply is non-repairable once damaged.

To resolve this problem, civil engineer technicians and researchers in scientific research units have carried out long-term exploration in the aspects of construction technique, concrete additive, mix proportion of concrete, and the unprocessed materials of concrete, reaching great achievement and gaining invaluable experience[1].
Due to the continued hydration of unhydrated cementitious materials needs water, when anhydrous or hydration water consumption rate is greater than the outside water migration rate, inside the concrete occurs moisture migration, and thus the internal pore will form a concave surface, then the formation of this concave surface will produce tension within the concrete, resulting in contraction, and this contraction is the autogenous shrinkage.
The factors include designs, materials, procedures of construction and other aspects.

The large amount of organic materials among ship wastes is a valuable resource.
Therefore, vessels are adopting the treatment method of metal cans recycling, which means firstly separate aluminum cans and steel cans, then enable the separated materials to be put into recycling again.

Convective boundary condition corresponds to the existence of convection (heating/cooling) at the surface, which assumes that heat conduction at the surface of the material is equal to the heat convection at the surface in the same direction.
