At present, domestic steel is facing severe challenges. As the country's investment declines, the real estate industry enters a period of adjustment, and the overall growth of the Chinese economy slows down, steel companies continue to struggle.
If the cancellation of the ratio requires the introduction of foreign investment, it is mainly to adjust the indicators and optimize the structure, and promote foreign investment in the use of new technologies, new processes, new materials, new equipment, and further improve the quality of foreign investment. For steel, it is beneficial to introduce foreign advanced technology to improve the quality of long-term low-value-added products in the country. This method can also increase the competitive advantage and thus forcefully enhance the competitiveness of enterprises. This will help companies accelerate the elimination of backward production capacity.
To promote the development of green building materials from the national level is not only a major test for the building materials industry, but also a rare opportunity. It can be foreseen that green building materials will become a huge market in the future, and foresighted building materials companies that have embarked on the road to green development earlier will seize the opportunity under this major government decision. The use of new building materials will not only greatly improve the function of houses, but also make the interior and exterior of buildings more modern and satisfy people's aesthetic requirements.
Relevant statistics show that the country’s total energy consumption for building energy consumption is more than 28%. Of the existing 40 billion square meters of buildings, 99% are high energy-consuming buildings. According to international experience and China's current development forecast for building energy use, by 2020, China's building energy consumption will account for about 35% of the total energy consumption of the entire society, and it will surpass industrial energy to become the first field of energy use.
Optical Microscopy
In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.
