The Comprehensive Management Study Of Enteromorpha Prolifera By Experiments

There are so many Green tides of marine pollution caused by Enteromorpha prolifera in northern seas in China in recent years. The pollution not only damages the environment but also affects the coastal landscape. The comprehensive management research of Enteromorpha prolifera has become a hot topic.In the year of 2008, there is a large-scale disaster of Enteromorpha prolifera flaring up in Qingdao, China. The moving line of it is forecasted by satellite, and a special machine like whale is manufactured to stop Enteromorpha prolifera from floating toward to the venues for sailing competition of the Olympic Games. The experiment of spot offshore is successful on the basis of the Lake Test. The result indicates that this machine could clear up the pollution of Enteromorpha prolifera in time and achieve the desired goals.Along with the quickly development of construction, environment noise and sound quality of auditorium control engineering, the new kind of low-cost, high-performance sound absorbing material is increasingly demanded. So the feasibility of applying it for new kind of sound absorbing material is investigated. Different thickness and structure of Enteromorpha prolifera is tested in standing wave tube for its sound absorbing property, which is compared with other fiber materials. Results of the experiments show that Enteromorpha prolifera has good absorption property, and the microtubule structure of it mainly contributes to its absorption property. The structure of Enteromorpha prolifera is not found in the man-made sound absorbing fiber so far. This discovery not only reveals the good characteristics of sound absorption in its fiber, but also provides the theoretical basis for utilizing it as a new kind of architecture sound-absorbing material. At last, computer simulation experiment for Enteromorpha prolifera applied for a sound absorbing material is made on the platform of the architectural acoustics software ODEON.In summary, in the processing of the comprehensive research, many kinds of technologies such as locating, forewarning and detection, salvage, development and utilization are systemic researched by combination simulation in lab with spot experiment, a number of stages of scientific research are accessed.
