Diffuse Reflector

The reflective properties and illumination uniformity of the polymer can be improved effectively with microstructure on the surface and scattering particles with high refractive index inside. The paper is based on the early research of the author. The reflector cup is processed by injection molding using the polymer of high reflective properties, which can achieve high efficiency of the light energy utilization and the uniform emergent ray.

Critical Timing

When daily energy budgets were calculated by two methods for tautog, Tautoga onitis, from fertilization to complete yolk absorption at three temperatures (16, 19, and 22 C), neither method indicated a deficiency of yolk energy for growth and metabolism prior to exogenous feeding capability. Deficits were indicated on the day of feeding capability at all temperatures by the oxygen consumption method, the more precise but less inclusive of the two. The dry weight method, which gave the more conservative estimates, indicated no deficit for the entire period of yolk absorption at 16 C, a deficit one day after feeding capability at 19 C, and a deficit on the day of feeding capability at 22 C.Regression analysis of oxygen consumption indicated that 22 C may be in the upper temperature limits for normal metabolism by embryonic and prolarval tautog. Yolk utilization efficiencies and postlarval size at complete yolk absorption tended to be inversely related to temperature. The ecological implications and the effects of temperature on the critical timing involved in the interactions of feeding capability, availability of prey and occurrence of energy deficits are discussed.

Hull Design

To solve the problem of rapid development of domestic water tourism and water pollution in scenic waters, windsurfing technology and solar photovoltaic technology are applied to small and medium-sized sightseeing cruise ships. While optimizing the hull design and component coordination, the application of automatic control technology further improves the utilization efficiency of wind and light energy, and achieves the adaptation of the sail angle of attack and the efficient coupling of the two energies. The ship mainly uses the natural resources of solar energy and wind energy. It will not burn fossil fuels during the ship’s travel, thus reducing the emission of toxic and harmful substances, which has positive significance for environmental protection. In short, the solar wind-assisted power generation ship studied in this project has remarkable features such as zero emission, high degree of intelligence, significant wind-assisted effect, high efficiency of light energy utilization, and low hull space occupation. Compared with the ordinary lake area cruise ship, the energy-saving and emission reduction effect of the power generation ship is very obvious[1].
