A system comprised of the nonlinear Schrodinger equation coupled to the Boussinesq equation (S-B equations) which dealing with the stationary propagation of coupled non-linear upper-hybrid and magnetosonic waves in magnetized plasma is proposed. To examine its solitary wave solutions, a reduced set of ordinary differential equations are considered by a simple traveling wave transformation. It is then shown that several new solutions (either functional or parametrical) can be obtained systematically, in addition to rederiving all known ones by means of our simple and direct algebra method with the help of the computer algebra system Maple.

Using the forms of Newton iterative function, the iterative function of Newton’s method to handle the problem of multiple roots and the Halley iterative function, we give a class of iterative formulae for solving equations in one variable in this paper and show that their convergence order is at least quadratic. At last we employ our methods to solve some non-linear equations and compare them with Newton’s method and Halley’s method. Numerical results show that our iteration schemes are convergent if we choose two suitable parametric functions λ（x） and μ（x）. Therefore, our iteration schemes are feasible and effective.

Microwave Resonator Sensors for Grains Moisture Measurements

第一届国际测量仪器与测试自动化学术会议

＜正＞This paper introduces the recent research and progress of microstrip and cavity sensors to measure grain moisture content. A miniaturized micro-strip ring resonator （MRR） 1 in.× 1 in. resonating at fro=10.2.GHz, was used as a nondestructive moisture sensor for chickpea kernels and wheat grains for ease in loading and unloading. The change in the resonant frequency（ △fr） of the MRR is a measure of the amount of moisture in the overlaid kernel. The development of microwave techniques and a separate gas displacement method to measure the wet-mass, moisture content of single wheat grain kernels are described. The perturbation of the circularly symmetric TM010, mode inside a cylindrical cavity is used with a linear model to determine the single grain moisture content and wet-mass. Finally the analysis and the discussion for measurement results is introduced respectively.
