We establish the existence of travelling wave solutions for delayed cooperative recursions that are allowed to have more than two equilibria. define an important extended real number is used determine speeds solutions. The results can be applied a large class reaction–diffusion models. show Lotka–Volterra competition model, there exists finite positive characterized as slowest speed connecting mono-culture equilibria or with coexistence equilibrium.
This paper considers a generalized Nicholson’s blowflies system with nonlinear density-dependent mortality terms and patch structure. Under appropriate conditions, we establish some criteria to ensure that the solutions of this exist converge globally exponentially positive almost periodic solution. The results complement another case in Chen Wang [5].
High temperature depleted gas reservoir has the huge potential of heat mining. In this article, method geothermal energy exploitation in high by injection supercritical CO2 was proposed based on analysis thermal properties and conventional transmission fluid-H2O. Meanwhile, numerical simulations were conducted to analyze mining capacity related influence factors reservoir. The results show that not only can exploit energy, but also enhance ultimate recovery achieve geological storage....
Many demonstration projects conducted in recent years have proved that CO2 capture and geological storage (CCS) can be an effective technology to reduce the emission of greenhouse gases. The prospective sites under investigation mainly include deep saline aquifers, depleted oil gas reservoirs unminable coal seams, which should huge capacity sequestrate safely permanently. Technically, CCS method is feasible acceptable public, but safety economics are main concerns. There three types leakage...
Evaluating the correlation between changes in design rainstorms and extreme rainstorm events under climate change facilitates flood control disaster reduction. Based on daily rainfall data of 609 stations during 1958–2017, Pearson-III curve, least square method, F-test, other methods were adopted to study response over nearly 60 years China, explore capacity engineering change. The conclusions are as follows. (1) There is a general increasing trend China. Most indices present upward trends...
Abstract The development and evolution of atmospheric long waves have an impact on predictability, are very important to improve weather forecast climate prediction. In addition wave‐wave nonlinear interaction, basic flow is also a significant factor for adjustment waves. Based equation the Rossby wave in non‐uniform flow, numerical solution calculated study effects field initial linear wave. result indicates that presents zonal flow. Therefore, another mechanism not sensitive amplitude...
Abstract Elucidating the mechanism of soil erosion caused by extreme rainstorms could improve agroecosystems' resilience to climate. However, less attention has been paid regional difference during through multiple field investigations. Using six surveys rainstorms, and its driving were investigated on farmland in Loess area Rocky mountain area. Conclusions are as follows: (1) Farmland was severely eroded comparison with abandoned land forest–grass land. The modulus (51 606.51 t/km 2 )...
