These existing synthetic materials are not suitable for coronary bypass or for small calibre (<5mm) arteries where the occlusion rates are highest.
POSS incorporated PCU polymer synthesis has been described in detail. [22] POSS based polymer materials have shown to be biostable and the bypass grafts designed using the polymer have a greater degree of compliance match to natural arteries compared to PTFE and Dacron, the conventional less-compliant materials currently in use.[23] We have established a technique for the production of porous grafts[24] and the rheology of the POSS biopolymer [25] is a key parameter in the preparation of the scaffolds in this way.

Sandwich structure is an attractive structural design concept by a proper choice of material; it can produce strong and light materials.
Skin must be selected from high strength materials and core from low strength materials, but its higher thickness provides strong and light materials will be produced [10].

Some large forest areas generally adopts 3S to conduct forest fire control: to do fire monitoring via RS technology; as an information conduction platform, GIS makes material collection, storage, conduction, space analysis and statistics, and inquiring, and then on this basis, it provides relevant information of aid decision making; GPS make contribution to the firemen to get accurate positions and guiding.

Mixed failure patterns were observed for all materials.
Until the 1980s, bracket which could be bonded directly to a tooth using of the acid-etch bonding systems was developed and reduced requirement of banding.1 This evolution has improved the overall treatment results because it improves esthetics, offers easier plaque removal and easier detection and treatment of dental caries by the practitioner.2 Many materials have been used in orthodontic bonding; however, light-cured systems offer a number of significant advantages in comparison with self-cured materials.

Theoretical basis and target of the system design Theoretical basis of the system design.Groundwater flows in rock and soil pore,fissure and solution fissure,its movement and exchange of materials are in form of seepage,seepage field is closely related to the underground engineering,especially the coal floor water inrush accident occurred in the process of mining[2-4].The forms of the coal floor water inrush are unexpected,but the process of water inrush is gradual,which is the process of seepage field continuously migrating upward through turning up fissures.Therefore,through embedding distributed electrode devices,using high density electric instrument to measure the laws of the characteristics of electric field of the groundwater and its existing space,real-time monitoring of the seepage electric field,one can get the changes of the apparent resistivity intuitively,which inevitably inverses the process of the seepage of the groundwater.One Sends the data collected by the electric instrument
