Introduction With the improvement of material life and spiritual pursuit, people need more in living condition.
An ecologic residential quarter needs to reduce the pavement area of the ground and increase the use of materials which have good water permeability.
The key of roof material is selection of the upper soil and the plant.
Upper soil should choose clean natural or artificial material with high porosity, small density and available for plant growth.

The structure design of the mini underwater robot Yufeng Wei1,a, Fang Liu2,b, Fei Hu3,c, Fanrang Kong4,d 1,2,3,4School of Engineering Science, University of Science and Technology of China, Hefei Anhui 230027, China awyf1541@mail.ustc.edu.cn, bliufang1@mail.ustc.edu.cn, cfeihu@mail.ustc.edu.cn, dkongfr@ustc.edu.cn Keywords: Underwater robot; Structure design; Resistance calculation.
Nevertheless, the shape and material adopted depends on two main factors: the first one is designed depth of the underwater robot, the other one is the payload of the underwater robot.
Through considering comprehensively, we selected 5454-aluminum alloy as the main material of the main cabin, and PC (polycarbonate) engineering plastic as the material the half-ball shell. 3.3 Stress calculation of the main cabin The robot will deform when squeezed by the seawater.
Although when water pressure increased to a certain value which still within the strength of material, the main cabin lost symmetry due to the overlarge deformation.

Additionally, it is interesting to note that, although originally the development of the SrTiO3/Si heterostructure was mainly motivated by the potential use of SrTiO3 as a high-k material, the present research has actually shown the SrTiO3/Si structure can be a good reference for integration of other perovskite oxide devices on Si.[9] The heterostructure of BST/high-R silicon for tunable microwave devices is one good example.

Currently, the achievement of a super mirror finish still relies largely on the experience and skills of the machine operators through an expensive trial-and-error approach when new materials, new design of surfaces or new machine tools are used [4] .
Although some attempts have been made in the development of machining models to simulate surface topography of a machined surface [5] , most of them do not take into account the effect of the cutting strategy, machining kinematics, cutting theories, material science, machine tool wear, 3D slide axis errors and temperature and thus fails to achieve optimization of the surface quality.

Introduction In recent years, the research of nature biofiber used as filler or reinforced materials caused the interests of people[1].
It’s necessary to take some measures to treat the biofiber or polymer matrix, in order to make the heterostructure materials easily dispersed and integrated in the process of compounding, which further to form a stable, firm and uniform interfacial layer.
