Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Space-based 100-m light condensing reflectors can undergo considerable structural deformations. The simple and accurate analysis of a concentrator system is important, especially when the system has large deformation errors. Further, slope error measurement of large reflectors is challenging. Gaussian distribution and other calculation models cannot accurately characterize the continuous changes of the actual model. Moreover, the analysis of fully fitted deformed surfaces is complicated. Therefore, this paper proposes a method for approximating surfaces by planers. The side lengths of the planes affect the speed and accuracy of modeling. Therefore, this paper analyzes the influence of the side length of the modeling plane and derives the allowable maximum side length of the plane. The model is also analyzed to ensure that its slope error does not change compared to the actual model during the modeling process. Spherical concentrators have great advantages in spatial concentrating owing to their rotational symmetry. Herein, the error model of a spherical low-ratio concentrator is calculated. Finally, an experiment is designed to verify the correctness of the calculations.
