Salinity stress greatly impacts rice grain yield and quality, as well as the 2-acetyl-1-pyrroline(2-AP) content in grains. The present study was conducted with Nanjing 9108(NJ9108, conventional japonica rice) and Wenliangyou 669(WLY669, indica hybrid rice) in the fields with non-salinity(NS), low salinity(LS), and high salinity(HS) stresses in 2021 and 2022.

The dual argument is well known for recoving the optimal L2-error of the finite element method in elliptic context. This argument, however, will lose efficacy in hyperbolic case. An expansion argument and an approximation argument are presented in this paper to recover the optimal L2-error of finite element methods for hyperbolic problems. In particular, a second order error estimate in L2-norm for the standard linear finite element method of hyperbolic problems is obtained if the exact solution is smooth and the finite element mesh is almost uniform, and some superconvergence estimates are also established for less smooth solution.

Consider -△u=f in rectangle Ω, u=0 on Ω. Let u_h∈S_h be bilinear Galerkin projection of u. We proved the following: 1) superconvergence D_(xy)~2(u-u_h)=0(h^2Inh)|u|_(4,∞) at center Z_j of each rectangle element τ_j holds; 2) we can construct a piecewise linear contitnuous function w^h by D_(xy)~2u_h and define q_h∈S_h satisfying(▽q_h,▽v)=-1/3(h^2+k^2)(w^h,D_(xy)~2v),v∈S_h;3) correction _h=u_h+q_h are of high accuracy u-_h=0(h^4|Inh|~2)‖u‖_(4,∞);4) by _h the correction derivatives can be got such that Du-=0(h^3 |In h|~2)‖u‖^(4,∞).

In this paper the authors discuss the additional conditions under which a Hungarian semigroup is possessed of the fundamental Delphic properties. It is proved that both the positive generalized renewal sequence semigroup and the tame semi-p-function semigroup are Hungarian semigroups and possessed of the fundamental Delphic properties. Then the arithmetic properties of these two classes of the special semigroups are studied respectively.
