The kings prblems in semicomplete digraphs without vertices whose in-degree are zero and locally semicomplete digraph under some conditions are discussed chiefly in the paper.

Analysis of internal length scales and strain localization for the four order rate dependent and gradient-dependent model;

A discussion on internal length scales and strain localization for rate dependent and gradient-dependent model with second and fourth order;

In this paper it is again discussed that the influence of extension or contraction deformation of honeycomb wallboard on in-plane stiffness.

The results indicate that the maximal indoor temperature difference between test hot-box(with PV-Trombe wall) and the reference hot-box(without PV-Trombe wall) can reach to 6 ℃,the maximal difference between the indoor temperature of test-hot box and the ambient can reach to 18 ℃.

The control process of indoor temperature by thermostat and the important concepts concerned in the design are introduced.

Through the analysis of the equation,it is found that the elastic instability is relevant to the radius,intrinsic scale and instable wavelength of the cylinder.

The second order parameters 〈P_2〉_λ and the values of introrse intensity Q in different shells of the droplets on 2DR boundary conditions at different reduced temperatures were calculated.
