Unfortunately, an error occurred in the author affiliations. The corrected authoraffiliations are given here:

1. The number of the affiliation of the first author “Wen-zheng Xu” is NOT “5” but “1, 2”. Because “Wen-zheng Xu” is the first author, the number of the affiliation should be “1, 2”. Thus, the authors and the corresponding affiliations should be corrected as following:

2. Due to my incaution and negligence, in the affiliation of the first author “Wen-zheng Xu”, the zip code is NOT “10083” but “100191”. Thus, the correct affiliation is “1. School of Automation Science and Electrical Engineering, Beijing University of Aeronautics and Astronautics, Beijing100191, China; 2. College of Chemical Engineering and environment, North University of China, Taiyuan 030051, China”, as is corrected above.
