Scaffold materials that have been frequently used are homo- or heteropolymers of poly(lactide) (PLA), poly(glycolide) (PGA) and poly(lactide-co-glycolide) (PLGA).
As commercial building materials used in SLS are not biodegradable and biocompatible, SLS application in TE scaffold construction remains limited.

Combined with the gray fuzzy evaluation method, project post evaluation on the Huaihe River engineering was conducted in this paper.
As the increasing investment in Irrigation works, especially the Huaihe River engineering, more attention has been paid to by the government.
Which kind of indicators to choose and whether the indicator is accord with the actual engineering, will matters not only the credibility, but also the workload.
It depends on the reliability of the material, the compatibility of the evaluation methods.
But it should emphasize the key, concluding the feasible and specific Suggestions.

Electrospinning is an important method for preparing nanofibers, which are highly promising for applications in a wide range of fields such as purification/filtration, photoelectric devices, battery separators, catalysis and tissue engineering.
These applications often use composite materials and have specific requirements for mechanical properties.
Those composite modes include changing the interlacing of fiber thickness, multi-layer composite of different materials, etc[7-9].
Both the MSM film and the MNSSM film are completely mixed spinning of two materials.

Biomaterials have a hierarchical structure with outstanding mechanical properties that are far beyond those additional engineering materials.
Mechanics theories on the stiffness, hardness, strength and toughness of biomaterials can be expected to play a key role in developing bio-inspired multi-functional and hierarchical materials in future.
Generally, adopting some light alloy and composite materials as well as the light structure, such as honeycomb, rumple and foam, is a key approach to implement high performance material and structural efficiency.
The mechanical properties of these raw materials are common.
Traditional methods for testing the mechanical properties of macro-scale engineering materials are unreachable until the nano indentation techniques were developed [20].

This report on physical limit attainment has challenged R&D engineers to develop innovative solutions to tackle the shortcomings of these traditional materials and thus emerging ECU thermal concerns.
Nonetheless, the key challenge for engineers remains developing improved materials that are cost competitive with traditional thermal management materials.
Conclusion A review of traditional materials and key issues in R&D of novel materials for thermal management of automotive ECU has been presented in the paper.

The landslide has been in good condition since this controlling engineering was completed several years ago.
However, due to the complexity of geotechnical engineering, it is still necessary to carry out further research on these problems.
Similar materials According to certain similarity ratios and physical and mechanical parameters of rock-layers, the similar materials are made through appropriate mixture ratio of barite powder, iron powder, sand, and water, and the physical and mechanical parameters of similar materials for relevant rock-layers can be obtained.
Comparing theoretical value with test one, we can find that the selected similar materials basically meet the requirements of similar design intent, which provides assurance for the reliability of final research results.
Conclusions With stable condition and desired repeatability, 6 types of similar materials have approximate theoretical and actual values for key physic-mechanical parameters, which is beneficial to the simulation of key lithologic characters and geological structure of sliding mass under consideration.
