A preliminary study on the degradation kinetics of phosphorus exchange in the process of large Experiments were used three different large algae ulva, kelp, AGAR weed ()All algae in October 2012, collected from weihai international bathing Washing, drying, weighing, algae it into a 500 ml conical flask, after using the filtered water and Each algal set three parallel samples and set up the three sea blank In temperature 20 ℃, 5000 Lux light intensity, light cycle: L D = 12: h under cultivation, respectively in five days, ten days, fifteen days after In 882 nm wavelength measuring absorbance value of samples, the phosphate concentration in the samples by phosphate standard curve calculation, and then take the dead algae body degradation process in different periods of the release quantity of phosphate and evaluation of large algae contribution to nutrient load of water Results show that: in the primary stages of decay, three kinds of seaweed are phosphates, release a large amount at this point, the algal death body is one of the sources of phosphate water Later, the degradation of the algae body speed gradually slow down, phosphate release a quantity to reduce, at the same time into colloidal substances adsorbed phosphate in the Due to the decomposition from the combined impact of release and adsorption dead algae body to a certain extent have played an important role in regulating the concentration of phosphate in 我的可以吗?
The system is an application software based on B/S(Browser/Server),it achieves communication between processes by using sockets,including network programming technology like TCP,UDP communication programming,thereby achieving the goal of LAN communication,functions like the managgement of friends and private chat This system mainly apply to the communication within small units' LAN( lntranet) like schools and companies to solve information communication between different users in same LAN and realize resource-sharing between users better at the same 希望对你有帮助!
Abstract: The system is based on B / S (browser / server) applications, including TCP and UDP communication programming, network programming using sockets to achieve inter-process communication, so as to achieve LAN communication, including friends such as management and private chat Including friends such as management and private chat The system is mainly used in schools, companies and other communications within a small unit within the LAN in order to solve the communication of information between different users within the same LAN, but also better able to achieve resource sharing between
