The difference between yellow ray laser pointer and blue

The difference between yellow ray laser pointer and blue ray laser pointer will be contained.
The majority of the low level of industrialization, small-scale, high-performance materials to be imported. Electronic ceramic materials production to meet domestic demand, but the quality of products, especially electronic ceramic components, the chip level and international level gap. Domestic battery materials in terms of uniformity, consistency, electrical / chemical properties than the capacity of foreign products, there is a gap. Magnetic materials focus on developing high-performance soft ferrite, ferrite, anisotropic bonded permanent magnet, microwave ferrite nanocrystalline magnetic material and talent recording material (high-performance fine metal magnetic particle, high-performance metal heads materials, magnetoresistance and magnetoresistive materials and giant magnetoresistance materials, etc.). This kind of red ray laser pointer  have three functions.The past five years the team commitment to scientific research "973" project, a project of "863" 4, 4 National Outstanding Youth Foundation, the National Natural Science Foundation of two major research of national and provincial ministries or international cooperation projects number. A National Natural Science Award, Zhejiang Science and Technology 2 first prize, second prize 3. More than 400 articles published in core journals at home and abroad, in which SCI more than 200 articles. laser pointer is more expensive.
Silicon Materials of Zhejiang University State Key Laboratory deputy director of Cheung Kong Scholars, National Outstanding Youth Fund winners. Long been engaged in semiconductor silicon materials and photovoltaic materials, silicon-based optoelectronic materials and nano-semiconductor materials. In the silicon crystal growth and defect engineering (in particular, to achieve significant results in defects in basic research of China's intellectual property in Nitrogen Czochralski Silicon) to obtain a State Natural Science Award, Zhejiang Science and Technology a prize, a second prize of Science and Technology in Zhejiang Province. Published more than 220 SCI papers and has 23 national invention patents. Ancient mythology, has spread the story of the "telescope" and "ears". People fantasy to see the landscape thousands of miles away.  To solve this typical problem, education industry has attached great importance on the close combination of teachers experience, habits and the modern teaching equipments including laser pointer .
