Transfer models were developed with overall wetting condition and part overall wetting and some water droplets larding in air condition. The relative errors of efficiency prediction are small than 2 percent because Lewis factor is equal to 1.The method to determine the mean saturated line slope of moist air was presented, which can apply to hot water and air. The wall wetting rate has remarkable effect on cooling efficiency. But water droplets in air effects are small and can be ignored in engineering calculations.

Since the installation of fire safety is not a part of a building structure and the seismic building design code does not include fire water pipings, the design of them in Taiwan does usually not consider the seismic effect. This study first collected and summarized the relevant seismic design codes and fire control standards from U.S., Japan, China and Taiwan to understand the internationally adopted methods for seismic from designs of fire water pipings. This study also gathered engineering cases and photographs of the installation of the shock resistance hangers of fire water pipings in high technology factory buildings. Then, this study presented a proposal for seismic design principles. we hope this can attract attentions from government authorities and the fire safety business sector and to rise concerns of the seismic design of fire safety installation; and therefore set up a clear and practical criterion for the engineers and finally reduce the damage of post earthquake fires.

Based on the test of practical measure of laser water-level gauge, the error is less than 0.6mm in the measure range less than 5 meters. Compared with other field water-level measure apparatuses in common use, the precision of laser water-level gauge has obvious improvement. And this gauge can also be applied to physical modeling experiment in river engineering.
