Traditional building materials, such as cement, clay brick production etc, consume too much energy and cause great pollution.
And because these materials are heavy, floors and concrete beams are often the direct cause of the casualties when an earthquake comes.
Therefore, at this stage it is urgent to develop environment-friendly building materials and low-carbon, light seismic building structures[1,2].
The composite bearing wall of the structural system has a cavity to ensure good thermal insulation properties, and on this basis it can be filled in the wall cavity or covered outside with thermal insulation materials.
Steel-bamboo composite wall has functions of maintenance and separating and can be filled with all kinds of heat preservation, thermal insulation, and waterproof materials.

Eutectic alloys are important to materials engineering, causing extensive theoretical and experimental study of the relationship between microstructure and solidification conditions.
Tin-lead solder for metal interconnects were widely used until the early 2000s when policies restricting the use of toxic materials in electrical and electronic equipment began [8].

In this paper, with fatty alcohol polyoxyethylene (AEO9), succinic anhydride (SA) and sodium hydroxide as raw materials, a new type of fatty alcohol polyoxyethylene carboxylate surfactants (SAE9C-Na) was obtained by esterification and neutralizing effect.
The main materials and instruments 1) Materials The AEO9 used in our study was commercial grade and obtained from Jiangsu Haian petrochemical plant e-commerce department.
In other words, molar ratio of alcohol to acid was too low to increase the yield, but when it reached too high, it would cause serious waste of materials, raise product cost and the difficulty for purification treatments.

The state of the art technology to cut these parts within a high volume production is a progressive punching process using metal strips from coils as semi-finished materials.
As a result, material thicknesses from 0.05 up to 0.5 mm for many metal materials used in industry can be remote cut by means of single mode fiber laser with final velocities between 50 and 1000 m/min.
