With intense anthropogenic perturbations in the Changjiang (Yangtze) River basin, riverine loads and compositions of materials into Estuary have greatly changed, resulting dramatic deterioration adjacent sea environments. Based on a long-term data set material Estuary, changing trends associated impacted factors were presented. The results showed downward concentrations dissolved silicate (DSi) over past 50 years due to dam constructions River. However, nitrogen (DIN) inorganic phosphate...
Abstract The biogenic elements concentrations in a coastal bay/estuary are strongly influenced not only by riverine input but also submarine groundwater discharge (SGD) which has been identified as typical process of land/ocean interactions zones. To assess the role SGD nutrient fluxes Southern Yellow Sea (SYS), 228 Ra activities were measured seawater collected May 2014. Analyzing sources and sinks Ra, flux excess through was estimated to be (2.2 ± 1.0) ×10 15 dpm yr −1 . Based on mass...
Abstract Although rare earth element (REE) has been widely applied for provenance study and paleoenvironmental reconstruction, its mobility fractionation during surface processes from weathering to sediment deposition remain more clarification. We investigated the REE fractionations chemical river transport based on systematic observations a granodiorite‐weathering profile Mulanxi River sediments in southeast China. Two phases (leachates residues) were separated by 1 N HCl leaching leachates...
Resonator micro-optic gyro (RMOG) is a promising candidate for the next generation inertial rotation sensor based on Sagnac effect. A current modulation technique used in an external cavity laser diode proposed to construct gyroscope system first time. The resonance curves before and after eliminating accompanying amplitude are theoretically analyzed, calculated, simulated; demodulation with different currents formulated theoretically; optimum corresponding maximum sensitivity obtained....
In the field of microscale energy storage, fabrication micro-supercapacitors (MSCs) with high power density and has always been a focus research. this work, laser-induced porous graphene chemically deposited manganese dioxide nanoparticles are used as electrode materials, switchable MSC two storage principles is obtained by designing symmetric interdigitated square structures. The aim to overcome preparation challenge supercapacitors switching between modes. MSC, mode (5.89 μW h cm-2) 3.36...
Based on the Sagnac effect, a resonator micro-optic gyro (RMOG) is novel optical sensor used for measuring rotation velocity. Due to advantages of small volume, narrow linewidth, and tunable wavelength, an external cavity laser diode (ECLD) adopted. By analyzing working mechanism ECLD, new scheme constant temperature driving current tuning control determined. First, theoretical resonance curve calculated. Then frequency successfully tracked in RMOG. Finally, bias stability 1.6 deg/s over 600...
