By using 3s technology, the dynamic crop information system can be developed to meet the needs of sharing the agriculture information in Shaanxi Province. The dynamic crop information system can realize the query of crop information attribute and space, and the automatic acquirement, dynamic distribution and classification analysis of crop information. In this way, the whole process of real-time management of agricultural product with information and visualization can be carried out, which is to improve the level of agriculture information management automation in Shaanxi Province. 展开更多

Shuangtaizi estuary wetland, the largest natural conservation district in China, and one of the best preserved, largest ecological lands with the most complete vegetation types in the world, is located in Panjin city, Liaoning Province. In recent years, the degradation of Shuangtaizi estuary wetland is very serious. In order to rescue lives in the wetland and protect valuable natural resources, the information system of Shuangtaizi estuary wetland was built with '3S' technology, and the minimum, optimum, and maximum eco-environmental water requirements were calculated respectively. Furthermore, for restoring the ecological functions of wetland and preventing wetland degradation, the balance between supply and demand of water resource was analyzed , and an optimal allocation scheme of water resources was proposed based on three kinds of equilibrium. 展开更多

We construct the integrable deformations of the Heisenberg supermagnet model with the quadratic constraints (i) S2=3S - 2I, for S ∈ USPL(2/1)/S(U(2)×U(1)) and (ii) S2=S, for S ∈ USPL(2/1)/S(L(1/... We construct the integrable deformations of the Heisenberg supermagnet model with the quadratic constraints (i) S2=3S - 2I, for S ∈ USPL(2/1)/S(U(2)×U(1)) and (ii) S2=S, for S ∈ USPL(2/1)/S(L(1/1)×U(1)). Under the gauge transformation, their corresponding gauge equivalent counterparts are derived. They are the Grassman odd and super mixed derivative nonlinear Schrodinger equation, respectively. 展开更多

As a sister work of[Phys. Rev. D 79 (2009) 094004], we incorporate the color-screening effect due to light quark pair creation into the heavy quark-antiquark potential, and investigate the effects of screened potential on the spectrum of bottomonimn. We calculate the masses, electromagnetic decays, and E1 transitions of bottomonium states. We find that the fine splittings between χbJ (J = 0, 1, 2) states are in good agreement with experimental data, and the E1 transition rates of γ(2S) → γχbJ(1P) and γ(3S) →γχbJ(2P) (J = 0, 1, 2) all agree with data within experimental errors. In particular, the mass of γ(6S) is lowered down to match that of the γ(11020), which is smaller than the predictions of the linear potential models by more than 100 MeV. Comparison between charmonium and bottomonium in some related problems is also discussed. 展开更多
