Abstract: Particles size grading method was employed to fabricate aluminum matrix composites reinforced with 75% volume fraction B4C particles by squeeze casting.
Therefore, dynamic behaviors of the composites should be taken into consideration in engineering design, meanwhile, related mechanism needs to be comprehensively understood.
This may bring about applied limitation of this kind of composite and the disadvantage should be taken into consideration in engineering design.
Each compression stress-strain curve was verified by using at least three samples for each material.

Abstract.
From the data in Table 1, it can be seen that the deck slabs have little function to resist bending moment and torsion but great function to resist axial force; this kind of structure makes full use of the material characteristics of steel and concrete to effectively solve the problem of “deck slab cracking when a composite girder is used in a cable-stayed bridge”.

Abstract: The Carbon emission trading mechanism is an important tool to tackle climate change, promote low-carbon economic development, and facilitate ecological civilization construction.
For the causes of environmental problems, economists maintain that external diseconomy is a key factor.
Multiple emission rights can co-exist at the same time on a material carrier of environmental capacity resources.
