At present, the deterioration of the environment is aggravating. The study of non-pollution soil moisture materials can improve the environment to a certain extent. In this paper, the network structure and water absorption molecular scale of hydrogels are studied by means of electron microscope. In this paper, the soil moisture hydrogel was taken as the research object. Firstly, NaOH and acrylic acid...
The real-time measure of network performance is crucial for many network applications. In order to ease the overhead introduced by various host-based network performance measure methods, a router-based hop-by-hop advertise scheme for network state announce service is proposed in this paper. The scheme provide network state announce service for all hosts in a single route-domain with the measure overhead...
Two-section shift-layer DFB lasers are fabricated to realize tunable lasers with high single-mode stability and wavelength converters with reshaping capability. 5.2-nm of wavelength tuning and conversion over 30-THz of input frequencies are demonstrated.
