The design idea and design flow of the simulation software on the complex reaction kinetics are introduced in this article. Firstly, the total framework of the software was determined by the goal and function of the software; Secondly, the manuscript was written, the multimedia material was made and the computational programs were designed, the examples of making multimedia material by Photoshop and Flash are introduced, moreover, the thinking and method of program is introduced; Finally, The material such as text, images, sounds, animation is integrated by Authorware. The simulation software has friendly interface and simple operation, it can be used as a computational tool in studying chemical kinetics, in addition, the software can be assisted in the teaching such as physical chemistry and reaction engineering.
To meet the demands of different high bandwidth services, we demonstrated a hybrid access network simultaneously transmitting wired and wireless signals. In the downstream, wireless signals are modulated and transmitted in phase modulation format at the optical carrier and wired signals are re-modulated in intensity modulation format, different de-modulation schemes are used at optical network unit (ONU) side; In the upstream, carrier reuse technology are adopted to re-modulate and transmit uplink signals to the optical line terminal (OLT). Simulation results show user ends could get acceptable performance of the wirless and wired signals.
The method to analysis the rheological property of the crosslinked polymer microspheres is presented in this paper. The flow curves and hysteresis loop areas of different swelling time and different mass concentrations of microspheres gotten. Through the above experimental data, the flow pattern and the time-dependent property are judged. Combined with the environmental scanning electron microscope images of microspheres, we can draw the conclusion that the concentration has obvious effects on the rheological property of the microspheres.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
