The author considers a three-species ratio-dependent predator-prey model with time delay in a two-patch environments. This model is of periodic coefficients, which incorporates the periodicity of the environment. By means of the coincidence degree theory, sufficient conditions for the existence of at least one positive periodic solution of this model are established. Moreover, The author shows that the system is uniformly persistent under the conditions.

Sulfonated polyether ether ketone （SPEEK） based composite membranes for direct methanol fuel cell （DMFC） application were prepared by sol-gel reaction of tetraethoxysilane （TEOS） in the SPEEK matrix and the incorporation of phosphotungstic acid （PWA）.The conductivity of the developed membranes was determined by impedance spectroscopy and the methanol permeability through the membranes was obtained from diffuseness *** SEM images show that the addition of SiO2 and the covalent cross-linking structure lead to fine PWA particles and more uniformly *** swelling of composite membranes remains in the range of 5%-8% at 30-90 ℃ and the effusion of PWA reduces *** composite membranes show a good balance in higher proton conductivity and lower methanol *** cell with composite membrane has higher open circuit voltage（0.728 V） and higher peak power density（45 mW/cm2） than that with Nafion117.

As a new direct metal prototyping technology,the hybrid plasma and laser deposition manufacturing (PLDM) is proposed in this paper. In order to figure out the characteristics of plasma arc beam and mould in the PLDM process of high temperature alloy, the high speed CCD camera is used to obtain the picture around the plasma arc. Afterwards the sketch of picture is clearly obtained. And the effect of laser parameter, such as average power, pulse width, pulse repetition frequency and the angle between laser beam and plasma arc beam on the plasma arc appearance, is studied experimentally. The results show that the modality of plasma arc beam is markedly influenced by laser beam. And the improvements of shape precision and surface state of the layer deposited by PLDM are confirmed.
