查询词典 on the beam

We haveour own intelligent property rights. Among them our spotlight is one of our typical products. It's the first time that the image illumination technology is used on the spotlight in the world. The reachable distance is raised 2-3 times, its beam of light angle is raised 5-6 times, and much power and energyis saved and illumination well-distributed. There is little color difference, comet difference and color difference for a point. Our spotlight can represent the latest technology of the same products in contemporary age and is granted national invention patent and national new practical patent.

According to the property of EBB, scanning electron beam was considered as plane heat source instead of spot heat source in this paper. Aiming at the problems to measure the real-time temperature and residual stress of radiator difficultly at high temperature, the two-dimensional finite element models were established. Based on the thermal elastic-plasticity, the temperature fields and stress fields of EBB 6139T and 6204T radiator by two kinds of process were simulated by the software of ANSYS. It is of great value and significance to guide actual production.

Under the excitation of 488 nm light beam of argon ion laser source, single suprahelical species could be observed with the aid of a common microscope due to the strong scattered light emitted by the suprahelical species. By capturing the RLS images of the single suprahelical species with a cooled charge coupled device camera, and analyzing the RLS data, herein an RLS imaging method of DNA was proposed based on the linear relationship between the counts of suprahelical species in the detection focus plane and the concentration of DNA in nanograms.
